The best peace lily fertilizer balances gentle feeding with an application routine you can follow; among these 15 options, Gardenera Liquid Peace Lily Fertilizer Concentrate is my best overall pick for its targeted 3-1-2 formula. For a larger bottle, FOLLOWIN Peace Lily Liquid Fertilizer stands out, while Miracle-Gro Indoor Plant Food suits shoppers who prefer a familiar, ready-to-use liquid. The main tradeoff is between concentrated formulas that need dilution and sprays that are easier to apply but may not replace root feeding. Read on for the full breakdown, how I ranked the options, and how to choose a fertilizer that fits your plant-care habits.

Key Takeaways
- Gardenera Liquid Peace Lily Fertilizer Concentrate leads the roundup because its peace-lily-specific 3-1-2 formula offers a clear starting point for routine feeding.
- FOLLOWIN’s 21-ounce bottle is the standout for shoppers who want a larger supply; bottle size alone does not make a formula stronger, so follow its label dilution directions.
- Liquid concentrates and ready-to-use foods serve different routines: concentrates require measuring and dilution, while ready-to-use options reduce prep but may offer less control over dose.
- Sprays are the convenience-focused group, not automatic substitutes for soil feeding. Choose a mist for surface application and use the product label to guide whether it supports your regular feeding plan.
- Several products share a 3-1-2 label profile, so the comparison often comes down to format, volume, and intended use rather than the ratio alone.

More Details on Our Top Picks
HiThrive Peace Lily Liquid Fertilizer, 16 oz
HiThrive’s main advantage is reach: its 16-ounce concentrate makes up to 96 gallons, so a bottle can serve a collection of peace lilies through many feeding sessions. Its listed nutrients include nitrogen, phosphorus, potassium, calcium, magnesium, and zinc, giving it a broader stated nutrient mix than the TPS Nutrients Peace Lily Fertilizer Spray, which emphasizes convenient misting but provides no coverage details. HiThrive can go into the soil or be used for bottom watering, giving owners more control over application. The tradeoff is that it needs dilution, and its peace-lily-specific formula is less flexible for a mixed houseplant collection than Houseplant Resource Center Indoor Plant Food. I’d choose it when predictable concentration and plant-specific use matter more than a ready-to-use format.
Pros:- One 16-ounce bottle makes up to 96 gallons
- Lists macro- and micronutrients, including calcium, magnesium, and zinc
- Can be applied to soil or used for bottom watering
- Formulated for peace lilies and multiple varieties
Cons:- Must be diluted before application
- Peace-lily-specific formula is less suited to feeding a varied houseplant collection
Best for: Peace lily owners with several plants who want a concentrated formula with stated coverage and multiple watering options
Not ideal for: People seeking a ready-to-use spray or one fertilizer for a broad mix of houseplants, since this concentrate requires dilution and targets peace lilies
- Brand:HiThrive
- Form:Liquid
- Volume:16 fluid ounces
- Coverage:Makes up to 96 gallons
- Mixing ratio:1:10
- Target plant:Peace lily
- Key nutrients:Nitrogen, phosphorus, potassium, calcium, magnesium, zinc
Our verdict“Choose HiThrive if you want a peace-lily-specific concentrate with stated high coverage and flexible watering methods.”
Peace Lily Fertilizer Spray, 16 fl oz
This TPS Nutrients spray is the simplest application option in this group: it is made for indoor peace lilies and applies as a mist, with no mixing instructions or watering-can setup described. That makes it a straightforward fit for someone who prefers a quick, direct routine over measuring concentrate. Compared with HiThrive Peace Lily Liquid Fertilizer, it gives up stated coverage, nutrient details, and the choice of soil or bottom-water application; HiThrive is the more informative pick for buyers who want to plan repeated feedings. The spray’s listing also does not say how much to apply or how often, so I would not choose it if precise dosing guidance is a priority. Its peace-lily focus is useful for a dedicated plant, but less convenient for a home feeding several kinds of houseplants.
Pros:- Spray format avoids mixing fertilizer in a separate container
- Designed specifically for indoor peace lilies
- Intended to support foliage, vitality, and flowering
- Made in the USA
Cons:- No coverage, dilution, or application-frequency details are provided
- Peace-lily-specific positioning limits its usefulness for a varied plant collection
- The supplied information does not list its nutrient analysis
Best for: Indoor peace lily owners who prioritize a quick mist application and do not need a stated dilution ratio or coverage estimate
Not ideal for: Buyers who want transparent nutrient or dosage details, or who need one product for a range of houseplants
- Brand:TPS Nutrients
- Form:Liquid spray
- Application method:Spray
- Target species:Peace lilies
- Volume:16 fluid ounces
- Number of items:1
- Made in:USA
Our verdict“Pick this spray if convenience matters more than detailed dosing information or multi-plant versatility.”
Houseplant Resource Center Indoor Plant Food, Organic Liquid Fertilizer, 8 oz
Houseplant Resource Center is the flexible choice for homes where a peace lily shares space with other indoor plants. Its 3-1-2 NPK ratio and chelated micronutrients are stated alongside a broad target list, so it can fit a feeding routine that includes plants such as pothos, monstera, and peace lilies. Unlike the peace-lily-only Gardenera Liquid Peace Lily Fertilizer Concentrate, this option does not tie its use to one plant type. It can be diluted for a watering can or spray bottle, and its urea-free formula is another specific point of distinction. The cost of that versatility is an 8-ounce bottle that still needs dilution; HiThrive offers much greater stated coverage for peace lily owners focused on a single plant group.
Pros:- 3-1-2 NPK ratio is clearly stated
- Includes chelated micronutrients
- Suitable for a range of houseplants, including peace lilies
- Urea-free and usable with a watering can or spray bottle
Cons:- Requires dilution before use
- The 8-ounce bottle has less stated volume than HiThrive’s 16-ounce bottle
- Broad houseplant positioning may be less appealing to buyers who want a peace-lily-specific formula
Best for: Houseplant owners who want one diluted fertilizer for peace lilies and a varied indoor collection
Not ideal for: People seeking a ready-to-use product or a peace-lily-only formula with a specified per-gallon mixing ratio
- Brand:Houseplant Resource Center
- Form:Liquid
- NPK ratio:3-1-2
- Volume:8 fluid ounces
- Application method:Dilute for use with a watering can or spray bottle
- Target plants:Houseplants, including peace lily, Dracaena, cast iron plant, snake plant, and spider plant
- Formula detail:Urea-free with chelated micronutrients
- Made in:USA
Our verdict“Choose this if your peace lily is part of a mixed houseplant collection and you want a stated 3-1-2 formula.”
Gardenera Liquid Peace Lily Fertilizer Concentrate, 3-1-2, 8 fl oz
Gardenera makes the mixing step easy to plan by specifying one teaspoon per gallon of water, and its 3-1-2 formula is a useful point of comparison for shoppers choosing a peace-lily concentrate. The product is described as organic and formulated for peace lilies, which gives it a more focused role than Houseplant Resource Center Indoor Plant Food, a 3-1-2 option intended for a broader houseplant range. The narrower focus may suit owners who want a dedicated product, while the stated ratio reduces guesswork at preparation time. The tradeoff is that it still requires mixing, and the supplied description presents growth and flowering support as product claims rather than independently verified results. Compared with HiThrive, it has less stated volume and no coverage estimate.
Pros:- Formulated specifically for peace lilies
- States a 3-1-2 formula
- Provides a clear mixing direction of one teaspoon per gallon
- Described as an organic plant food
Cons:- Requires dilution before application
- No coverage estimate is provided
- Growth and flowering benefits are product claims in the supplied description, not independently verified
Best for: Peace lily owners who want a dedicated liquid concentrate with a stated 3-1-2 formula and per-gallon mixing direction
Not ideal for: Buyers who prefer ready-to-use feeding or want a documented coverage estimate and broader nutrient details
- Brand:Gardenera
- Form:Liquid concentrate
- Formula:3-1-2
- Volume:8 fluid ounces
- Target plant:Peace lily
- Mixing ratio:1 teaspoon per gallon of water
- Pack quantity:1
- Product description:Described as organic
Our verdict“Choose Gardenera if you want a peace-lily-specific concentrate with a simple, stated mixing ratio.”
Miracle-Gro Indoor Plant Food, Liquid, 8 oz Bottles, 2-Pack
Miracle-Gro is the broadest-use pick here: it is listed for indoor plants ranging from houseplants and peace lilies to flowers, vegetables, and herbs. Two 8-ounce bottles provide 16 ounces total, matching HiThrive’s bottle volume while serving a much wider range of plants. Its direct-to-soil or diluted application also offers flexibility, and the instructions give a concrete option of four pumps in a quart of water. The tradeoff is a recommended weekly schedule, which calls for more frequent feeding than a buyer may want to manage. Compared with Houseplant Resource Center Indoor Plant Food, Miracle-Gro supplies a two-bottle pack and direct application, while Houseplant Resource Center states a 3-1-2 ratio and urea-free formula. This is the practical choice for mixed indoor planting, not a dedicated peace lily formula.
Pros:- Suitable for peace lilies and a wide range of indoor plants
- Can be applied directly to soil or diluted in water
- Provides a dilution direction of four pumps per quart
- Two 8-ounce bottles provide 16 ounces total
Cons:- The listed feeding schedule calls for weekly use
- Intended for indoor container plants rather than a peace-lily-specific feeding program
- No NPK ratio or coverage estimate is provided in the supplied product details
Best for: Households feeding several kinds of indoor plants who want both direct-to-soil and diluted application options
Not ideal for: Peace lily owners seeking a plant-specific formula or a less frequent routine than the listed weekly application
- Brand:Miracle-Gro
- Form:Liquid
- Bottle size:8 fluid ounces
- Pack quantity:2
- Total volume:16 fluid ounces
- Application frequency:Once a week
- Application:Apply to soil or dilute four pumps in one quart of water
- Suitable for:Indoor plants, including peace lilies, flowers, vegetables, and herbs
Our verdict“Choose Miracle-Gro if you feed a variety of indoor plants and value flexible application over peace-lily-specific formulation.”
Gardenera Organic Liquid Kelp Fertilizer for Peace Lilies, 8 oz
For peace lily owners drawn to a seaweed-based formula, this concentrated liquid uses Ascophyllum nodosum and is described as supporting foliage, roots, and blooms. Its standout practical advantage is yield: one 8-ounce bottle makes up to 45 gallons of nutrient solution, which can suit a collection of plants or a long-term feeding routine. Compared with GARDENWISE Peace Lily Liquid Fertilizer, which specifies a 3-1-2 ratio and micronutrients, Gardenera emphasizes kelp rather than a stated NPK balance. That makes the two options difficult to compare by nutrient numbers alone. The tradeoff is narrow stated use: it is formulated for peace lilies, so it is less versatile than Leaves and Soul’s concentrate for peace lilies and other indoor plants. Buyers should also follow the label for dilution and feeding frequency.
Pros:- Ascophyllum nodosum seaweed formula
- An 8-ounce bottle makes up to 45 gallons of solution
- Intended to support foliage, roots, and blooms
- Suitable for indoor and outdoor peace lilies
Cons:- Stated use is limited to peace lilies rather than a broad range of houseplants
- No NPK ratio is provided in the product data for straightforward nutrient comparison
Best for: Peace lily owners who prefer a seaweed-based concentrate and want a high dilution yield for repeated feeding.
Not ideal for: People seeking one fertilizer for a mixed houseplant collection, since the stated formulation is specifically for peace lilies.
- Brand:Gardenera
- Volume:8 fluid ounces
- Plant type:Peace lilies (Spathiphyllum)
- Key ingredient:Ascophyllum nodosum seaweed
- Dilution yield:Makes up to 45 gallons
- Use:Indoor and outdoor plants
- Made in:USA
Our verdict“Choose this if a kelp-based peace lily concentrate and high dilution yield matter more to you than a stated NPK ratio or broader plant compatibility.”
Gardenera Plant Superfood Spray for Peace Lilies, 8 fl oz
This is the lineup’s spray-first option, suited to peace lily owners who want to apply plant food directly over leaves and stems instead of mixing a concentrate into watering. Its listed ingredients include vitamin B-1, glucose, iron, manganese, and zinc, and the directions call for weekly application year-round. Compared with Gardenera Organic Liquid Kelp Fertilizer, this spray gives more detail about its vitamins and micronutrients, while the kelp concentrate offers a stated yield of up to 45 gallons and is mixed for watering. The tradeoff is that a spray routine adds a separate step, and the directions also recommend watering after sunset, which may not fit every household’s schedule. It is not a direct substitute for a measured liquid feed if you prefer fertilizer mixed into your regular watering routine.
Pros:- Spray application goes over leaves and stems
- Lists vitamin B-1, glucose, iron, manganese, and zinc
- Suitable for indoor and outdoor peace lilies
- Weekly, year-round directions are provided
Cons:- Requires a separate weekly spraying step
- The recommendation to water after sunset may not suit every routine
- Does not provide a dilution yield for comparison with concentrated liquid feeds
Best for: Peace lily owners who prefer a weekly leaf-and-stem spray and want a routine with listed vitamins and micronutrients.
Not ideal for: People who want to add fertilizer only through watering or cannot accommodate the product’s recommendation to water after sunset.
- Brand:Gardenera
- Product type:Plant food spray
- Volume:8 fluid ounces
- Key ingredients:Vitamin B-1, glucose, iron, manganese, and zinc
- Suitable for:Indoor and outdoor peace lilies
- Directions:Spray over leaves and stems weekly
Our verdict“Pick this for a weekly foliar-feeding routine; choose the Gardenera kelp concentrate instead if you prefer mixing fertilizer into water.”
GARDENWISE Peace Lily Liquid Fertilizer, 3-1-2, 8 fl oz
GARDENWISE makes nutrient comparison easier by stating a 3-1-2 fertilizer ratio and including essential micronutrients. It can be diluted at 1:128 for watering or foliar application, giving peace lily keepers a choice between feeding through the root zone and spraying. Compared with Leaves and Soul Peace Lily Liquid Fertilizer Concentrate, which also lists a 3-1-2 formula, GARDENWISE specifies its 1:128 dilution and two application methods; Leaves and Soul lists a 1:4 mixing ratio and broader use for indoor plants. These ratios should be followed as each product directs rather than treated as interchangeable. GARDENWISE’s main compromise is specialization: its stated design is for peace lilies, so it is less appealing for a mixed collection. The concentrated format also requires careful measuring and dilution before use.
Pros:- States a 3-1-2 fertilizer ratio
- Includes essential micronutrients
- Can be used for watering or foliar application
- Concentrated 1:128 dilution
Cons:- Designed specifically for peace lilies, limiting its stated use for other plants
- Requires accurate measuring and dilution before application
Best for: Peace lily owners who want a stated 3-1-2 ratio, micronutrients, and the option to apply fertilizer through watering or as a foliar solution.
Not ideal for: Houseplant owners looking for one clearly broadly marketed fertilizer for several plant types, or anyone who would rather not measure and dilute concentrate.
- Brand:GARDENWISE
- Fertilizer ratio:3-1-2
- Form:Liquid
- Dilution ratio:1:128
- Volume:8 fluid ounces
- Designed for:Peace lilies (Spathiphyllum)
- Application methods:Watering or foliar application
- Manufacturer:Summit Sales Company LLC
Our verdict“Choose GARDENWISE if a stated nutrient ratio and two application methods are priorities for your peace lily care routine.”
Leaves and Soul Peace Lily Liquid Fertilizer Concentrate, 3-1-2, 8 fl oz
Leaves and Soul is the more flexible 3-1-2 choice for buyers who care for peace lilies alongside other indoor plants. Its concentrated formula is intended for dilution, and the product data lists both peace lilies and indoor plants as suitable targets. That wider stated scope gives it an advantage over GARDENWISE Peace Lily Liquid Fertilizer, which is designed specifically for peace lilies and supplies a detailed 1:128 dilution instruction. Both products state a 3-1-2 formula, but Leaves and Soul lists a 1:4 mixing ratio; follow its own directions rather than assuming its mixing instructions match another concentrate. The main drawback is the extra preparation before each use, and the available details do not specify application frequency or a dilution yield. Its USA-made designation may appeal to some buyers, but it does not remove the need to measure carefully.
Pros:- 3-1-2 formula designed for peace lilies and indoor plants
- Concentrated liquid format
- Made in the USA
- Water-based mixing allows diluted application
Cons:- Must be diluted before use
- The stated 1:4 mixing ratio requires measuring
- Product data does not specify a dilution yield or application frequency
Best for: Indoor gardeners who grow peace lilies along with other houseplants and want a concentrated 3-1-2 fertilizer marketed for both.
Not ideal for: Buyers who want ready-to-use plant food or detailed application-frequency instructions in the supplied product information.
- Brand:Leaves and Soul
- Formula:3-1-2
- Form:Liquid concentrate
- Volume:8 fluid ounces
- Item weight:8 ounces
- Mixing ratio:1:4
- Target species:Peace lily
- Made in:USA
Our verdict“Pick Leaves and Soul if you want a concentrated 3-1-2 feed for peace lilies and other indoor plants, and do not mind mixing it before use.”
Cute Farms Organic Liquid Plant Food for Indoor Houseplants, 8 fl oz
Cute Farms suits indoor growers who want fertilizer built into every watering, with directions to use seven pumps in 16 ounces of water. The organic, urea-free, vegan formula is described as gentle enough for that frequent schedule, while the locking dispensing pump helps measure each dose without pouring from the bottle. Compared with Leaves and Soul Peace Lily Liquid Fertilizer Concentrate, Cute Farms offers a pump and an every-watering routine, but it does not state a 3-1-2 ratio or target peace lilies specifically. Its broader indoor-houseplant positioning may work for a mixed collection, though peace lily owners seeking a clearly tailored formula may prefer GARDENWISE’s stated 3-1-2 blend. The tradeoff is ongoing measuring and mixing, plus a routine that depends on how often you water; it is not a ready-to-use spray.
Pros:- Organic, urea-free, and vegan formula
- Dispensing pump helps measure each dose
- Described as gentle enough for use with every watering
- Suitable for indoor houseplants
Cons:- Requires dilution at seven pumps per 16 ounces of water
- Does not state a peace lily-specific formula or NPK ratio
- Every-watering use may not suit buyers seeking a less frequent feeding routine
Best for: Indoor plant owners who want an organic, vegan liquid feed with a pump-measured dose for use at every watering.
Not ideal for: Peace lily keepers who want a fertilizer explicitly formulated for Spathiphyllum or who prefer a stated NPK ratio and less frequent feeding directions.
- Brand:Cute Farms
- Form:Liquid concentrate
- Volume:8 fluid ounces
- Target plants:Indoor houseplants
- Mixing ratio:7 pumps per 16 ounces of water
- Application frequency:Every watering
- Ingredients:Organic, urea-free, and vegan
- Included component:Locking dispensing pump
- Country of manufacture:United States
Our verdict“Choose Cute Farms for pump-measured, every-watering feeding across indoor plants; choose GARDENWISE if a peace lily-specific 3-1-2 formula matters more.”
FOLLOWIN Peace Lily Liquid Fertilizer, 3-1-2 NPK, 21 fl oz
FOLLOWIN’s 3-1-2 blend pairs a balanced nutrient ratio with EDTA-chelated micronutrients, including iron, magnesium, and calcium. For a peace lily grower who also feeds other houseplants, that broader target range is more flexible than TPS Nutrients Peace Lily Liquid Fertilizer, which is formulated specifically for peace lilies. Its stated yield of up to 48 gallons makes this bottle a practical fit for a collection, while the measuring cap helps with routine mixing.
The tradeoff is that this is a concentrate, not a ready-to-use option: you need to dilute it before each application and follow the stated ratio. The bottle offers plenty of yield, but that advantage matters less if you care for only one plant and feed infrequently. I’d choose it for a multi-plant household seeking a general-purpose formula with a defined peace lily-friendly ratio.
Pros:- 3-1-2 NPK ratio suits foliage-focused feeding
- EDTA-chelated micronutrients include calcium, magnesium, iron, and zinc
- Stated yield of up to 48 gallons when diluted as directed
- Measuring cap supports portioning the concentrate
Cons:- Must be diluted before application
- Mixing requires measuring 10 ml per 0.8 gallon of water
- Its broad houseplant target may be less appealing to buyers seeking a peace-lily-only formula
Best for: Houseplant owners who feed several indoor species and want a concentrated 3-1-2 fertilizer with listed micronutrients.
Not ideal for: People who want a ready-to-use spray or who prefer a fertilizer formulated only for peace lilies; this product needs dilution and is positioned for multiple houseplants.
- Brand:FOLLOWIN
- NPK ratio:3-1-2
- Form:Liquid concentrate
- Volume:21 fl oz
- Mixing ratio:1 cap (10 ml) per 0.8 gal of water
- Stated yield:Up to 48 gallons when diluted as directed
- Micronutrients:EDTA-chelated calcium, magnesium, iron, zinc, copper, manganese, and boron
- Target plants:Houseplants, including peace lilies
Our verdict“Choose FOLLOWIN if you feed a wider houseplant collection and value a high-yield concentrate over a ready-to-use formula.”
TPS Nutrients Peace Lily Liquid Fertilizer, 8 fl oz
TPS Nutrients is formulated specifically for potted peace lilies, making it a more focused pick than the broad tropical-plant food from Miracle-Gro. Its 3:1:2 mixing ratio is presented as gentle feeding for sensitive roots, with the stated aim of supporting flowers, green leaves, and root development. That focused positioning suits owners who want a product selected for their plant rather than a general houseplant formula.
The narrower scope is also its main limitation: it is intended for peace lilies, so it is less convenient if you want one fertilizer for a mixed collection. It also needs to be mixed before use, unlike Gardenera Peace Lily Spray Fertilizer Mist, which arrives ready to apply. I’d pick TPS for a peace-lily-focused routine, but not for someone who values a spray bottle or a single feed for many tropical plants.
Pros:- Formulated specifically for potted peace lilies
- 3:1:2 ratio is stated in the product data
- Designed for gentle feeding of sensitive roots
- Targets flowering, foliage, and root development
Cons:- Limited to peace lilies rather than a broad houseplant range
- Requires mixing before use
- Product data does not specify a dilution volume or feeding frequency
Best for: Peace lily owners who want a fertilizer marketed specifically for the plant and prefer a measured liquid feeding routine.
Not ideal for: Growers with a varied tropical-plant collection or anyone who wants a ready-to-use mist instead of mixing fertilizer.
- Brand:TPS Nutrients
- Form:Liquid
- Target plant:Peace lily
- Volume:8 fl oz
- Mixing ratio:3:1:2
- Country of manufacture:USA
Our verdict“Choose TPS Nutrients if peace lilies are your focus and you are comfortable mixing a dedicated liquid fertilizer.”
Miracle-Gro Tropical Houseplant Food – Liquid Fertilizer, 8 fl. oz., 2-Pack
Miracle-Gro Tropical Houseplant Food makes the most sense for peace lilies that share a shelf with other tropical houseplants. Its listed micronutrients include magnesium, manganese, copper, iron, and zinc, and it is designed to start feeding instantly when applied. Compared with the peace-lily-only TPS Nutrients, this two-bottle set offers a broader use case for growers who want one product across several tropical plants.
That convenience comes with a more frequent routine: the stated schedule is weekly feeding in spring and summer. This is not a ready-to-use mist like Gardenera’s spray, and the product data does not give a mixing ratio, so buyers should follow the label directions rather than assume a dose. I’d rank it for mixed collections, but a grower seeking a peace-lily-specific formula or fewer feeding sessions may prefer another option.
Pros:- Formulated for a wide range of tropical houseplants
- Contains listed micronutrients including magnesium, manganese, copper, iron, and zinc
- Designed to start feeding instantly when applied
- Two 8 fl oz bottles provide a combined 16 fl oz
Cons:- Calls for weekly application during spring and summer
- Liquid feeding may be less convenient than a spray or other ready-to-apply format
- Product data does not state a dilution ratio
Best for: Owners of several tropical houseplants, including peace lilies, who are comfortable following a weekly spring-and-summer feeding schedule.
Not ideal for: Peace lily owners seeking a plant-specific formula, a ready-to-use spray, or a less frequent feeding routine.
- Brand:Miracle-Gro
- Form:Liquid fertilizer
- Pack quantity:2 bottles
- Volume:8 fl oz per bottle
- Key ingredients:Magnesium, manganese, copper, iron, and zinc
- Application frequency:Once per week in spring and summer
- Target plants:Tropical houseplants
Our verdict“Choose Miracle-Gro if you want one liquid food for a tropical plant collection and can keep up with weekly seasonal feeding.”
Gardenera Peace Lily Spray Fertilizer Mist, 3-1-2, 8 oz
Gardenera’s ready-to-use mist stands out for avoiding the measuring and mixing required by concentrated liquids such as FOLLOWIN Peace Lily Liquid Fertilizer. The 3-1-2 formula is made for peace lilies and is described as supporting foliage, blooms, and root growth. For someone with one or two plants who wants a straightforward spray-bottle format, that simplicity can matter more than high concentrate yield.
Its specific focus also limits its usefulness: unlike Miracle-Gro Tropical Houseplant Food, it is not positioned as a fertilizer for a broad collection of tropical species. The directions call for weekly or watering-time use and warn against overwatering, so adding liquid care needs to fit into a sensible watering routine. I’d choose this for convenience, not for multi-plant versatility or maximum dilution flexibility.
Pros:- Ready-to-use mist avoids preparing a diluted solution
- 3-1-2 NPK ratio
- Formulated for peace lilies
- Intended to support foliage, blooms, and root growth
Cons:- Targeted to peace lilies rather than a general houseplant collection
- Weekly or watering-time use requires attention to the plant’s watering routine
- Product data does not state a yield or a measured dose per plant
Best for: Peace lily owners who want to skip mixing and prefer a ready-to-use bottle for a small number of plants.
Not ideal for: People feeding many different houseplants or those who want a concentrate with a stated high dilution yield.
- Brand:Gardenera
- NPK ratio:3-1-2
- Form:Ready-to-use liquid mist
- Volume:8 oz
- Pack count:1
- Use:Peace lilies, indoor or outdoor
- Suggested timing:Weekly or at watering time
Our verdict“Choose Gardenera’s mist if ease of application matters more than broad use or concentrate-style yield.”
GrowThrive Organic Peace Lily Liquid Fertilizer, 10 oz
GrowThrive takes a microbial approach rather than highlighting a standard NPK ratio: its product data lists more than 5.9 billion CFUs per fluid ounce and describes the formula as supporting root health and plant growth. It is formulated for all peace lily varieties, from miniature to giant plants, so its scope is broader within the peace lily category than the single-use mist from Gardenera. A 1:400 dilution ratio also gives buyers a clear starting point for preparing a soil application.
This is still a concentrate, so it requires mixing, and its cap has no graduated markings. That makes accurate measuring less straightforward than with FOLLOWIN’s measuring-cap approach. The product data also does not provide an NPK ratio, which may matter to growers who want a conventional nutrient profile for comparison. I’d choose it for its microbial focus, not for the simplest measuring routine.
Pros:- Microbial formula lists over 5.9 billion CFUs per fluid ounce
- Formulated for all peace lily varieties
- Clear 1:400 dilution instruction
- Measuring cap is included
Cons:- Requires dilution before soil application
- Cap has no graduated markings, making measurement less precise
- Product data does not list an NPK ratio
Best for: Peace lily collectors who want a microbial-formula fertilizer suited to different peace lily varieties and are comfortable measuring a concentrate.
Not ideal for: Growers who want a ready-to-use spray, a listed NPK ratio, or clearly graduated measuring marks on the cap.
- Brand:GrowThrive
- Form:Liquid concentrate
- Volume:300 ml (10 oz)
- Mixing ratio:1:400
- Application method:Dilute with water and apply to soil
- Target plants:All peace lily varieties
- Bacterial count:Over 5.9 billion CFUs per fluid ounce
- Pack size:1
Our verdict“Choose GrowThrive if you value a peace-lily-specific microbial formula and can measure the concentrate carefully.”
How We Picked
I compared the 15 listed products on factors that shape a peace lily owner’s day-to-day results: whether the formula is marketed for peace lilies or indoor plants generally, the stated nutrient profile when provided, application format, bottle size, and the amount of measuring or preparation involved. I also looked at how clearly each option communicates its intended use. A fertilizer label and directions matter more than a broad claim of being “organic” or “plant food,” since feeding frequency and dilution can vary by formula.
The ranking favors products with a clear fit for peace lilies and a practical feeding format, then weighs ease of use and flexibility. That puts Gardenera’s 3-1-2 concentrate first as a targeted, legible choice; larger-volume and general-purpose liquids follow for shoppers who prioritize supply or familiarity. Sprays and kelp-based options have distinct use cases, but rank below straightforward root-feeding liquids for buyers seeking a main fertilizer. I do not treat bottle size, a product name, or an organic label as proof of greater strength or better results.

Factors to Consider When Choosing Best Peace Lily Fertilizers
Before choosing a bottle, match the fertilizer to your plant’s condition and your own routine. A peace lily in fresh potting mix or struggling with watering problems may not need added nutrients right away. These broader checks can help prevent overfeeding and clarify when a specialized formula is worth choosing.
Match the fertilizer to the actual problem
Slow growth does not always mean a peace lily needs fertilizer. Check light, watering, drainage, and root health first, since nutrient additions cannot correct soggy soil or poor growing conditions. Feeding a stressed plant can add another source of strain rather than solve the cause. If the plant is actively growing and its care conditions are stable, a measured feeding may make sense. This distinction matters because a targeted product name can make fertilizer feel like the answer even when the underlying issue is elsewhere.
Choose a format you can dose consistently
Concentrates give you control over dilution, but they ask you to measure carefully each time. Ready-to-use liquids reduce preparation, which can be helpful if you tend to skip tasks that require mixing. Sprays may fit a quick application routine, though you should check whether the label positions the product as a complete fertilizer or a supplementary treatment. Avoid combining formats just because each seems mild; overlapping applications can raise the total nutrient dose. The most useful format is one you can apply according to its directions without guessing.
Read the nutrient label, not just the front of the bottle
A stated NPK ratio gives more information than a general phrase such as plant food, but it does not tell the whole story. Products in this roundup include several labeled 3-1-2 formulas, yet that shared ratio does not make their instructions interchangeable. Concentration, dilution rate, and feeding schedule still matter. Check the label for the amount per volume of water and any guidance on frequency before you buy. If a product does not make its use instructions clear, choose an option whose directions are easier to follow.
Treat bottle size as convenience, not potency
A larger container can reduce how often you need to restock, but it does not necessarily provide a stronger or more economical feeding without knowing the dilution rate. Compare how much finished solution the product makes, not just the ounces printed on the bottle. A small concentrate may last longer than a bigger ready-to-use product, depending on its directions. Also think about storage: a bottle you can use before its stated shelf life is more practical than a bulk size that sits unused. This is why FOLLOWIN’s larger format suits frequent users, while a smaller bottle may fit a single-plant home better.
Know when to pay for a peace-lily-specific formula
A peace-lily-specific fertilizer can make shopping simpler when you want a product labeled for your plant, especially if its instructions are clear. A general indoor-plant food may still be a reasonable fit if its label supports use on foliage houseplants and gives a suitable dilution schedule. Specialized wording is not a guarantee of better performance, so compare directions and nutrient information rather than relying on the name alone. Pay more attention to dose control if your peace lily is small, recently repotted, or sensitive to accumulated fertilizer salts. For most buyers, clarity of use is a stronger reason to choose a product than niche branding by itself.
Adjust feeding to growth and care conditions
Indoor plants do not use nutrients at the same pace all year, and peace lilies often grow more slowly when light and seasonal conditions limit growth. Follow the product label rather than applying a fixed schedule copied from another fertilizer. If you are unsure how your plant responds, begin conservatively within the label directions and watch for changes in leaf condition and growth. Do not add extra fertilizer to compensate for missed applications. A steady, measured routine is easier to evaluate than frequent changes between products.
Frequently Asked Questions
Is a 3-1-2 fertilizer automatically the right choice for my peace lily?
A 3-1-2 ratio is a useful point of comparison, and several products in this roundup use that label profile. It does not by itself confirm that a product suits every plant or feeding routine. The concentration and dilution directions determine how much fertilizer reaches the pot. Compare the full label, including frequency and application method, rather than choosing by ratio alone. If your plant is not actively growing or has care-related stress, address those conditions before adding nutrients.
Can I use a fertilizer spray instead of a liquid added to the soil?
That depends on what the spray label says it is intended to do. A mist is easy to apply, but ease of use does not show whether it supplies the same kind of feeding as a liquid used according to soil directions. Check whether the product is described as a complete fertilizer or as a supplementary spray, and follow its application instructions. Avoid stacking a spray with a regular liquid feeding unless the labels support that routine. If you want one primary fertilizer, choose a product with clear directions for the feeding method you plan to use.
Should I fertilize a peace lily that has brown leaf tips?
Brown tips alone are not a reliable sign that a peace lily needs fertilizer. Water quality, inconsistent moisture, low humidity, and excess fertilizer can all contribute to leaf-tip damage. Review your watering habits and check for a buildup of fertilizer salts before adding more nutrients. If you recently fed the plant, pause additional feeding while you investigate the cause. Resume only when the plant’s care conditions are stable and the fertilizer label supports doing so.
Is the larger FOLLOWIN bottle a better buy for one peace lily?
The 21-ounce bottle offers more product on hand, but that does not automatically make it the better fit for a single plant. The amount of finished solution depends on the product’s dilution directions, and a large bottle is only useful if you can store and use it as directed. Compare the dose and feeding schedule with how often you plan to fertilize. A smaller bottle may be more practical for occasional feeding or a limited plant collection. Choose the larger format when its supply matches your routine, not simply because it contains more ounces.
Can I use general indoor plant food instead of a peace-lily-specific fertilizer?
Often, a general indoor plant food can be suitable if its label lists foliage houseplants or otherwise supports use on peace lilies. The product’s directions and concentration matter more than whether “peace lily” appears in its name. A specialized formula may make selection easier, but it is not a reason to ignore dosing guidance. Avoid assuming that two liquids with similar NPK ratios should be mixed or applied at the same frequency. When the label is unclear about use on houseplants, choose a product with more direct instructions.
Conclusion
For most readers, I recommend Gardenera Liquid Peace Lily Fertilizer Concentrate as the best overall choice because its peace-lily focus and 3-1-2 label make its purpose easy to judge. FOLLOWIN Peace Lily Liquid Fertilizer is my best value-style pick for buyers who want a larger supply, provided its dilution directions suit their routine. For beginners, Miracle-Gro Indoor Plant Food is a straightforward general-purpose option when clear label directions and familiar liquid application matter more than a peace-lily-specific name. Shoppers seeking a premium or more plant-targeted option can start with a dedicated concentrate such as Leaves and Soul or Gardenera, while buyers focused on spraying should compare the Gardenera mist and spray products carefully with their intended use in mind. Whichever you choose, let the label, your plant’s growth, and your feeding habits guide the dose—not the bottle size or product name alone.
