For steady indoor growth, I would start with Gardenera Peace Lily Liquid Fertilizer Concentrate, 3-1-2, my best overall pick for its targeted formula and measured application. Miracle-Gro Indoor Plant Food suits shoppers who want a familiar, multipurpose option, while Gardenera’s Seaweed & Kelp Concentrate stands out for a plant-food approach centered on kelp. The main tradeoffs are targeted versus general-purpose formulas, ready-to-use sprays versus concentrates, and organic-leaning ingredients versus conventional plant food. Match the product to how often you want to mix and feed, since an easy application routine matters as much as the label. Read on for the full comparison and recommendations by plant-care style.

Key Takeaways
- Targeted 3-1-2 concentrates lead this lineup for shoppers who want a peace-lily-focused formula and are comfortable measuring and diluting fertilizer.
- Ready-to-use sprays and mists reduce mixing, but they may be less appealing to buyers who prefer adding fertilizer to watering routines.
- General indoor plant foods offer wider use for homes with several houseplant types, while dedicated peace lily formulas prioritize a narrower use case.
- Bottle size does not tell the whole value story: concentrated products can make many batches, while ready-to-use options trade dilution work for convenience.
- The lineup includes several similar Gardenera choices; their main differences are application format and formula focus, so buyers should choose by routine rather than brand name alone.

More Details on Our Top Picks
Gardenera Plant Superfood Spray for Peace Lilies, 8 fl oz
Gardenera Plant Superfood Spray stands out for peace lily owners who want a foliage-applied supplement rather than a fertilizer they mix into water. Its blend lists vitamin B-1, glucose, iron, manganese, and zinc, giving it a different emphasis from TPS Nutrients’ liquid food, which is mixed for root-zone feeding and bloom support. The spray can be used on indoor or outdoor peace lilies and fits into a weekly care routine, so it is straightforward to apply without measuring a dilution ratio. That convenience comes with a recurring chore: weekly use is part of the directions, and this spray does not provide a listed NPK ratio or quantified feeding coverage. I’d choose it as a targeted supplement, not as the clearest option for buyers seeking a conventional, measured fertilizer program.
Pros:- Includes iron, manganese, and zinc micronutrients
- Vitamin B-1 is included to support root development
- Spray format avoids measuring a concentrate
- Suitable for indoor and outdoor peace lilies
Cons:- Directions call for weekly application
- No NPK ratio or mixing guidance is provided in the product data
Best for: Peace lily owners who want a weekly foliar spray with listed micronutrients and do not mind recurring applications
Not ideal for: Buyers seeking an NPK-labeled fertilizer, a soil-drench feeding routine, or a product with a stated dilution rate
- Brand:Gardenera
- Model number:PSF-SPRAY-PEACE-LILY-8oz
- Volume:8 fluid ounces
- Form:Spray
- Key ingredients:Vitamin B-1, glucose, iron, manganese, zinc
- Plant use:Indoor and outdoor peace lilies
- Recommended frequency:Weekly
Our verdict“Choose this spray for a simple, micronutrient-focused weekly routine, but pick an NPK-labeled liquid if you want a more defined feeding formula.”
Peace Lily Fertilizer, Liquid Plant Food for Longer Blooms, 8 oz
TPS Nutrients Peace Lily Fertilizer is the bloom-minded pick in this group: its product description centers on longer-lasting flowers alongside green foliage and root development. Unlike Gardenera’s ready-to-use 3-1-2 mist, this is a liquid that requires mixing, with a stated 3:1:2 ratio and a formula described as gentle for sensitive roots. That makes it a better fit for plant owners who prefer feeding through prepared solution rather than spraying leaves. The tradeoff is that the mixing step calls for care; the product data specifically flags precise dilution, but does not give a more detailed volume-based recipe. Its claims about brown tips and yellowing are appealing, though those symptoms can have causes beyond fertilizer. I’d favor it for bloom goals, while Gardenera’s mist is easier for no-measure application.
Pros:- Formulated specifically for peace lilies
- Description emphasizes longer blooms and lush foliage
- Includes a stated 3:1:2 ratio
- Gentle formula is described as suitable for sensitive roots
Cons:- Requires careful mixing to avoid incorrect dilution
- Product data does not provide a volume-based mixing recipe
- Claims about preventing leaf discoloration may not address non-nutrient causes
Best for: Peace lily owners prioritizing flower production who are comfortable measuring and mixing liquid plant food
Not ideal for: Beginners who want a ready-to-use spray or anyone who would rather avoid dilution measurements
- Brand:TPS Nutrients
- Model number:TPS-PEACELILY-8OZ
- Liquid volume:8 fluid ounces
- Pack count:1
- Mixing ratio:3:1:2
- Target species:Peace lily
- Specific use:Plant growth
- Manufacturer:TPS Nutrients
Our verdict“Pick TPS Nutrients if bloom support is your main goal and you are comfortable mixing; choose Gardenera’s mist for simpler application.”
Gardenera Peace Lily Fertilizer Mist, 3-1-2 Blend, 8 oz
Gardenera Peace Lily Fertilizer Mist makes feeding less of a measuring task: it is a ready-to-use 3-1-2 spray intended for weekly or watering-time application. Compared with Gardenera’s Plant Superfood Spray, this mist supplies a stated NPK ratio, while the Superfood version highlights vitamin B-1 and specific micronutrients. It also avoids adding fertilizer to the soil, a practical distinction for owners who prefer foliar application. The convenience is not a reason to spray indiscriminately: the product instructions caution against overwatering, and the supplied information does not quantify nutrient coverage or independent evidence for its growth and disease-resistance claims. I’d put it ahead of concentrates for ease of use, but behind a measured liquid feed for buyers who want a clearly described soil-watering routine.
Pros:- Ready-to-use spray requires no dilution
- Lists a 3-1-2 NPK ratio
- Formulated for peace lilies
- Can be applied without disturbing the soil
Cons:- Weekly use may add a recurring care task
- Instructions caution against overwatering
- Product data does not specify coverage or independently substantiate performance claims
Best for: Peace lily owners who want a pre-mixed fertilizer mist and prefer not to handle concentrate or measuring tools
Not ideal for: Buyers who want feeding by soil drench, a stated coverage amount, or detailed evidence behind growth and disease-resistance claims
- Brand:Gardenera
- NPK ratio:3-1-2
- Volume:8 ounces
- Form:Ready-to-use liquid mist
- Pack size:1
- Recommended use:Peace lilies
- Application:Weekly or at watering time
Our verdict“Choose this mist for convenient, no-mix foliar feeding, but use a liquid concentrate such as Gardenera’s 3-1-2 formula if you prefer a measured water-based feed.”
Gardenera Peace Lily Liquid Fertilizer Concentrate, 3-1-2, 8 fl oz
Gardenera Peace Lily Liquid Fertilizer Concentrate suits owners who want a defined recipe instead of a ready-to-use spray. Its 3-1-2 formula is diluted at one teaspoon per gallon, a practical reference point when preparing a watering can for a peace lily. Compared with Gardenera’s ready-to-use fertilizer mist, this concentrate takes more setup but is designed for mixing into water rather than spraying directly. The product is described as organic and intended to support growth, roots, and flowering, though the supplied details do not specify how often to feed. That missing schedule leaves buyers to follow any additional label directions and their plant-care routine rather than relying on the product summary alone. I’d rank it above the mist for measured feeding, but below products with clearer application-frequency guidance.
Pros:- Formulated specifically for peace lilies
- Lists a 3-1-2 formula
- Provides a specific dilution rate of one teaspoon per gallon
- Described as an organic liquid concentrate
Cons:- Must be diluted before application
- Product data does not state application frequency
- Requires preparation for each feeding rather than direct spray use
Best for: Peace lily owners who regularly prepare diluted plant food and want a stated 3-1-2 concentrate mixing rate
Not ideal for: People who want a ready-to-spray product or need a clearly stated feeding schedule in the product details
- Brand:Gardenera
- Formula:3-1-2
- Form:Liquid concentrate
- Volume:8 fluid ounces
- Target plant:Peace lily
- Mixing ratio:1 teaspoon per gallon of water
- Number of items:1
- Formula description:Organic
Our verdict“Choose this concentrate if a measured water-dilution recipe matters more than convenience, and prefer Gardenera’s mist for a no-mix option.”
HiThrive Peace Lily Fertilizer, 16 oz
HiThrive Peace Lily Fertilizer is the high-coverage choice here: its 16-ounce bottle is listed as making up to 96 gallons of feeding solution. That scale suits households with several peace lilies or owners who feed often; it is less compelling for someone with one small plant. The formula supplies nitrogen, phosphorus, potassium, and micronutrients, while its 1:10 mixing ratio is presented for use at every watering. Compared with the 8-ounce Gardenera concentrate, HiThrive offers a larger stated solution yield, but its every-watering routine means users need to measure consistently and avoid overfeeding. It is a liquid rather than a spray, so preparation is part of the job. I’d choose it for repeat feeding across multiple plants, not for occasional, minimal-input care.
Pros:- 16-ounce bottle is listed as making up to 96 gallons of solution
- Provides nitrogen, phosphorus, potassium, and micronutrients
- Designed for peace lilies
- Uses a stated 1:10 mixing ratio
Cons:- Must be mixed before use
- Directions describe use at every watering, which may not suit every routine
- Large stated coverage may be excessive for a small collection and requires careful measuring
Best for: Indoor gardeners caring for several peace lilies who want a larger bottle and routinely prepare liquid feed
Not ideal for: Owners with one or two plants who prefer occasional feeding, a ready-to-use spray, or less frequent mixing
- Brand:HiThrive
- Liquid volume:16 fluid ounces
- Form:Liquid
- Target species:Peace lily
- Mixing ratio:1:10
- Listed coverage:Up to 96 gallons of feeding solution
- Nutrients:Nitrogen, phosphorus, potassium, and micronutrients
- Recommended use:At every watering
Our verdict“HiThrive makes the most sense for multi-plant owners who want high stated coverage and can measure each feeding consistently.”
Gardenera Premium Organic Seaweed & Kelp Superfood for Peace Lily – 8 oz Liquid Fertilizer Concentrate (Makes 45 Gallons)
Kelp-based support sets this peace lily-specific concentrate apart from the balanced 3-1-2 fertilizers in this roundup, including Leaves and Soul Professional Peace Lily Fertilizer. Its organic seaweed formula supplies trace minerals and natural growth hormones, making it a targeted choice for growers focused on root development and foliage health. The claimed yield of up to 45 gallons from an 8-ounce bottle also suits someone who feeds multiple plants or wants a concentrate to last.
The tradeoff is precision: this formula requires careful dilution, and an overly strong mix may burn leaves. Unlike Miracle-Gro Indoor Plant Food, which serves a broader range of plants, this product is specifically formulated for peace lilies, so it is less flexible for a mixed collection. It may also be more than a single small plant needs if feeding is infrequent.
Pros:- Kelp-based formula includes trace minerals and natural growth hormones.
- Designed to support peace lily roots, foliage, and blooms.
- Concentrated 8-ounce bottle is stated to make up to 45 gallons of solution.
- Described as odor-free and suitable for indoor use around people and pets.
Cons:- Requires careful dilution to reduce the risk of leaf burn.
- Peace lily-specific focus makes it less versatile than general houseplant foods.
- The large potential yield may be unnecessary for a single small plant.
Best for: Peace lily owners who prefer an organic kelp concentrate and want one bottle to supply repeated feedings.
Not ideal for: Growers with a small, occasionally fed plant or a mixed collection who want one fertilizer for several plant types.
- Brand:Gardenera
- Form:Liquid concentrate
- Volume:8 fluid ounces
- Stated yield:Up to 45 gallons of feeding solution
- Plant focus:Peace lilies
- Formula:Organic seaweed and kelp
- Model number:KELP-PEACE-LILY-8oz
- Part number:KELP-PEACE-LILY-8oz
Our verdict“Choose this if you want a peace lily-specific organic kelp concentrate and are comfortable measuring a diluted feed.”
Miracle-Gro Indoor Plant Food, Liquid, 8 oz Bottles, 2-Pack
For peace lily owners who also feed other houseplants, this two-bottle pack prioritizes flexibility and simple application over a species-specific formula. The food can go directly onto soil or be diluted at four pumps per quart of water, and the stated weekly schedule suits growers who prefer frequent, small feeding routines. Compared with Gardenera’s kelp concentrate, it is a more general-purpose pick for a collection that includes peace lilies alongside herbs, flowers, or other listed plants.
That convenience comes with a routine: the product recommends weekly application, which can be less appealing than a concentrate used more selectively. The supplied details also do not list an NPK ratio, so buyers who want a clearly specified nutrient balance may prefer Houseplant Resource Center’s 3-1-2 formula. Choose this for easy repeat feeding, not for a narrowly tailored peace lily blend.
Pros:- Suitable for peace lilies and a range of other indoor plants.
- Can be applied directly to soil or diluted in water.
- Two 8-ounce bottles provide 16 fluid ounces total.
- Stated weekly use offers a clear recurring feeding schedule.
Cons:- Recommended weekly application may feel frequent for low-maintenance growers.
- The supplied product details do not state an NPK ratio.
- General indoor-plant positioning is less targeted than a peace lily-specific formula.
Best for: Indoor gardeners who want one liquid food for peace lilies and several other kinds of houseplants, with direct-use or diluted application options.
Not ideal for: Peace lily owners seeking a clearly stated NPK ratio or a feeding routine that does not call for weekly application.
- Brand:Miracle-Gro
- Form:Liquid
- Bottle size:8 ounces
- Pack size:2 bottles
- Total volume:16 fluid ounces
- Dilution guidance:4 pumps per quart of water
- Application:Apply directly to soil or mix with water
- Recommended frequency:Once a week
- Target plants:Houseplants, snake plants, croton, peace lilies, flowers, vegetables, and herbs
Our verdict“Pick this two-bottle liquid food if you value flexible application and feed several types of indoor plants on a weekly schedule.”
Houseplant Resource Center Indoor Plant Food, Organic Liquid Fertilizer, 8 oz
Gentle, measured feeding is the main reason to choose this formula for a peace lily. Its 3-1-2 NPK ratio supplies a stated nutrient balance, while chelated micronutrients add support beyond the basic NPK numbers. The urea-free formula is described as suitable for sensitive roots and seedlings, which makes it a more cautious option for delicate indoor plants than the weekly-use Miracle-Gro Indoor Plant Food in this lineup.
It is not ready to pour straight from the bottle: you must dilute it and apply it with a watering can or spray bottle. Compared with Leaves and Soul Professional Peace Lily Fertilizer, this product is positioned for a broader range of houseplants rather than peace lilies specifically. That versatility is useful for mixed collections, though buyers wanting a peace lily-only concentrate may prefer the more targeted alternative. The product details do not specify a dilution ratio, so follow the label for mixing.
Pros:- Stated 3-1-2 NPK ratio pairs with chelated micronutrients.
- Urea-free formula is described as suitable for sensitive roots and seedlings.
- Works across a range of indoor plants, including peace lilies.
- Can be applied with a watering can or spray bottle.
Cons:- Requires dilution before application.
- The supplied details do not give a mixing ratio.
- General houseplant focus is less peace lily-specific than Leaves and Soul’s formula.
Best for: Growers with peace lilies and other houseplants who want a stated 3-1-2 formula described as gentle on sensitive roots.
Not ideal for: People who want a ready-to-use feed or need a supplied dilution ratio before buying.
- Brand:Houseplant Resource Center
- Form:Liquid fertilizer
- NPK ratio:3-1-2
- Volume:8 fluid ounces
- Item weight:9 ounces
- Application method:Dilute and apply with a watering can or spray bottle
- Formula detail:Urea-free with chelated micronutrients
- Target plants:Houseplants, including pothos, peace lily, monstera, cactus, dracaena, and snake plant
- Made in:USA
Our verdict“Choose this diluted 3-1-2 food if gentle, multipurpose feeding matters more than a peace lily-specific label.”
Leaves and Soul Professional Peace Lily Fertilizer, 3-1-2 Liquid Concentrate, 8 oz
This is a strong fit for buyers who want a stated 3-1-2 nutrient ratio in a product expressly aimed at peace lilies. The balanced formula is presented as supporting roots, foliage, and blooms, while its liquid concentrate is intended to mix with water for root delivery. Compared with Houseplant Resource Center’s broader indoor-plant food, Leaves and Soul makes peace lilies its primary focus; compared with Gardenera’s kelp product, it provides a declared NPK ratio rather than centering its description on seaweed and trace minerals.
The main compromise is preparation: the concentrate needs dilution at the stated 1:4 mixing ratio, so it is not a ready-to-use shortcut. Its peace lily emphasis may also be redundant for someone feeding many unrelated plants. The 8-ounce bottle is compact, and the supplied information does not state a total solution yield, so shoppers should not assume it offers the same coverage claim as Gardenera’s kelp concentrate.
Pros:- Peace lily-focused formula has a stated 3-1-2 NPK ratio.
- Liquid concentrate is described as fast-absorbing and easy to mix.
- Formula is positioned to support roots, foliage, and blooms.
- Made in the USA.
Cons:- Requires dilution at the stated 1:4 mixing ratio.
- Peace lily emphasis may be less useful for a broad mixed-plant collection.
- Supplied details do not specify the total volume of diluted feed produced.
Best for: Peace lily owners who want a dedicated liquid concentrate with a clearly stated 3-1-2 ratio.
Not ideal for: Growers who want ready-to-use food, or those seeking one fertilizer primarily for a diverse collection of unrelated plants.
- Brand:Leaves and Soul
- Form:Liquid concentrate
- NPK ratio:3-1-2
- Volume:8 fluid ounces
- Weight:8 ounces
- Mixing ratio:1:4
- Target species:Peace lily
- Origin:Made in USA
Our verdict“Choose Leaves and Soul if you want a peace lily-focused 3-1-2 concentrate and do not mind mixing it before watering.”
Miracle-Gro Indoor Plant Food for All Plants, 8 fl. oz. (2-Pack)
This Miracle-Gro two-pack is a practical match for indoor growers who want a general-purpose liquid food and a stated every-two-weeks routine. It covers houseplants as well as herbs, vegetables, and flowers, so it can serve peace lilies without requiring a dedicated bottle for one species. Compared with the other Miracle-Gro two-pack in this batch, whose description recommends weekly feeding, this product’s stated schedule is less frequent and may suit owners seeking fewer feeding sessions.
It offers the same kind of application flexibility—direct to soil or mixed at four pumps per quart—but still asks the buyer to keep track of the dilution guidance and reapply regularly. The supplied details do not list an NPK ratio, unlike the 3-1-2 options from Houseplant Resource Center and Leaves and Soul. That makes this a convenience-led choice rather than the pick for shoppers who want a specified nutrient balance for peace lily care.
Pros:- Two 8-ounce bottles provide 16 fluid ounces in total.
- Suitable for houseplants, herbs, vegetables, and flowers.
- Can be applied directly to soil or mixed with water.
- Product description states an every-two-weeks feeding schedule.
Cons:- Requires regular reapplication rather than occasional feeding.
- Mixing calls for following the four-pumps-per-quart guidance.
- The supplied details do not state an NPK ratio or peace lily-specific formula.
Best for: Indoor gardeners who feed peace lilies alongside herbs, vegetables, or flowers and prefer a stated every-two-weeks schedule.
Not ideal for: Peace lily owners who want a dedicated formula or a clearly specified NPK ratio.
- Brand:Miracle-Gro
- Form:Liquid
- Pack size:2 bottles
- Bottle volume:8 fluid ounces
- Total unit count:16 fluid ounces
- Mixing ratio:4 pumps per quart of water
- Application:Apply directly to soil or mix with water
- Recommended frequency:Every two weeks
- Target plants:Houseplants, herbs, vegetables, and flowers
Our verdict“Choose this pack for a flexible, general-purpose feed with a stated every-two-weeks routine, not for a specialized peace lily nutrient profile.”
Peace Lily Fertilizer Spray, 16 fl oz
Direct mist application is the main reason this TPS Nutrients option earns a place in the roundup: it is made for indoor peace lilies and avoids mixing concentrate into water. The 16-ounce bottle offers more product than the 8-ounce GARDENWISE fertilizer, though the listed low coverage limits how far that advantage goes. Its stated purpose is to support green foliage, vitality, and flowering, making it a straightforward pick for owners who prefer a spray routine. Compared with the soil-applied GrowThrive formula, this product is easier to apply without preparing a dilute mix, but its spray format may be less practical for several large plants. Choose it for convenience, not for broad coverage or precise feeding control.
Pros:- Spray application skips mixing and dilution
- Designed specifically for indoor peace lilies
- Intended to support foliage, vitality, and flowering
- 16-fluid-ounce bottle
Cons:- Listed coverage is low, limiting usefulness across multiple plants
- Spray format offers less control over root-zone feeding than a diluted soil application
Best for: Peace lily owners with one or a few indoor plants who want a ready-to-spray application and do not want to measure concentrate.
Not ideal for: People feeding a large plant collection or seeking broad coverage, since the product listing identifies coverage as low.
- Brand:TPS Nutrients
- Form:Liquid
- Application method:Spray
- Target plant:Peace lilies
- Volume:16 fluid ounces
- Pack count:1
- Made in:USA
Our verdict“Choose this spray if easy, direct application matters more than high coverage or soil-directed feeding.”
GARDENWISE Peace Lily Fertilizer – 3-1-2 Liquid Fertilizer with Essential Micronutrients (8 oz)
For a peace lily kept away from bright windows, GARDENWISE is the most specifically positioned choice here: its description calls out low-light indoor settings and pairs a 3-1-2 formula with essential micronutrients. The stated 1:128 dilution gives owners a repeatable mixing target, but it also means this is not a ready-to-use option like the TPS Nutrients spray. Compared with FOLLOWIN, which names its chelated micronutrients and serves other houseplants too, GARDENWISE is the more peace-lily-focused pick, while FOLLOWIN may suit mixed collections better. Its 8-ounce bottle and plant-specific formulation narrow its appeal: it is a considered choice for a peace lily, not an all-purpose fertilizer for every pot on the shelf.
Pros:- Formulated with low-light indoor peace lilies in mind
- 3-1-2 NPK ratio with essential micronutrients
- Specified 1:128 dilution provides a clear mixing target
- Described as supporting leaf and root growth
Cons:- Requires accurate dilution before application
- Plant-specific formula is less versatile for mixed collections
- 8-fluid-ounce unit is smaller than the FOLLOWIN bottle
Best for: Indoor gardeners with a peace lily in a lower-light room who are comfortable measuring a concentrate and want a plant-specific formula.
Not ideal for: Owners seeking one fertilizer for a varied houseplant collection or a no-measuring spray, since this is peace-lily-specific and requires 1:128 dilution.
- Brand:GARDENWISE
- Manufacturer:Summit Sales Company LLC
- NPK ratio:3-1-2
- Unit count:8 fluid ounces
- Dilution ratio:1:128
- Target plant:Peace lilies (Spathiphyllum)
- Part number:GW-777
Our verdict“Pick GARDENWISE for a low-light peace lily when you want a focused liquid formula and can measure the dilution carefully.”
GrowThrive Organic Peace Lily Liquid Fertilizer, 10 oz
GrowThrive stands apart from the spray-led TPS Nutrients option by directing a microbial formula to the soil, where its stated focus is soil and root health. The listing gives a count of over 5.9 billion CFUs per fluid ounce and a 1:400 dilution ratio, making this a concentrated choice for gardeners who prefer a measured watering routine over misting foliage. Its coverage extends to houseplants, including all peace lily varieties, so it is more flexible than the peace-lily-only GARDENWISE formula. The cap can serve as a measuring cup, but it has no measurement markings; that makes accurate small-batch mixing less convenient than FOLLOWIN’s marked 10 ml cap. The microbial detail is a distinctive feature, though buyers should be comfortable measuring the dilution themselves.
Pros:- Microbial formula is described as supporting soil and root health
- Suitable for all peace lily varieties and other houseplants
- Concentrated 1:400 dilution
- Cap can be used as a measuring cup
Cons:- Cap has no measurement markings, complicating precise dosing
- Requires dilution and soil application rather than direct spraying
- Microbial formula may be a narrower fit for buyers seeking a basic, simple liquid feed
Best for: Peace lily owners who want a concentrated, soil-applied microbial formula and also keep other houseplants.
Not ideal for: Gardeners who want premeasured dosing, a ready-to-use spray, or clear measurement marks on the cap.
- Brand:GrowThrive
- Form:Liquid
- Volume:300 ml (10 oz)
- Mixing ratio:1:400
- Application method:Dilute with water and apply to soil
- Target plants:Houseplants, including all peace lily varieties
- Bacterial count:Over 5.9 billion CFUs per fluid ounce
- Cap capacity:Approximately 1.7 fluid ounces
Our verdict“Choose GrowThrive if soil and root support is your priority and you are willing to measure an unmarked cap carefully.”
FOLLOWIN Peace Lily Liquid Fertilizer, 3-1-2 NPK, 21 fl oz
FOLLOWIN is the lineup’s strongest fit for someone feeding peace lilies alongside other houseplants: its 3-1-2 NPK blend is paired with a named set of EDTA-chelated micronutrients, and the target list includes both peace lilies and other houseplants. The 21-fluid-ounce bottle is larger than GARDENWISE’s 8-ounce unit, while the cap’s 10 ml measure offers a more defined dosing tool than GrowThrive’s unmarked cap. There is a serious usability caveat, though: the product information gives conflicting dilution directions, listing 1 cap per 0.8 gallon in the specs and 1 cap per 1.6 gallons in the description. That inconsistency makes routine feeding harder to judge. I would favor it for its versatility and nutrient detail only if the buyer can confirm the correct dilution instructions.
Pros:- 3-1-2 NPK ratio
- Lists EDTA-chelated calcium, magnesium, iron, zinc, copper, manganese, and boron
- Suitable for peace lilies and other houseplants
- 10 ml cap provides a defined measuring amount
Cons:- Dilution directions conflict: 1 cap per 0.8 gallon versus 1 cap per 1.6 gallons
- Requires dilution before application
- Large stated coverage depends on following the correct mixing rate
Best for: Houseplant owners who want one liquid fertilizer for peace lilies and other indoor plants and can resolve the conflicting dilution directions before use.
Not ideal for: Beginners who need unambiguous mixing instructions or anyone unwilling to verify which listed dilution rate is correct.
- Brand:FOLLOWIN
- Form:Liquid
- NPK ratio:3-1-2
- Bottle volume:21 fluid ounces
- Item weight:8 ounces
- Dilution listed in specs:1 cap (10 ml) per 0.8 gallon of water
- Conflicting dilution listed in description:1 cap per 1.6 gallons of water
- Coverage:Makes up to 48 gallons when diluted as directed
- Micronutrients:EDTA-chelated calcium, magnesium, iron, zinc, copper, manganese, and boron
Our verdict“Consider FOLLOWIN for a mixed houseplant collection if you can confirm the correct dilution rate before feeding.”

How We Picked
I compared the 14 products on factors that affect peace lily care at home: whether the formula is marketed specifically for peace lilies, how clearly its NPK ratio or ingredient focus is presented, and whether it is a concentrate, liquid plant food, spray, or mist. I also weighed usability, dilution or application demands, bottle format, and whether a product is practical for one plant or a broader houseplant collection. A clear feeding approach matters because concentrated fertilizer can be economical to use but calls for accurate measuring, while ready-to-use formats simplify application.
The ranking gives priority to products that balance a peace-lily-oriented formula with a manageable feeding routine. That puts Gardenera’s 3-1-2 liquid concentrate first, with general indoor plant foods and the kelp concentrate serving different needs rather than being treated as interchangeable. Similar products are separated by format, stated formula, and intended audience; a larger bottle or targeted label alone does not automatically earn a higher place. Every pick has a tradeoff, so the best choice depends on how you feed, how many plants you maintain, and whether you want one formula for multiple species.

Factors to Consider When Choosing 15 Best Peace Lily Fertilizers For Healthy Indoor Growth
I would choose a fertilizer by starting with the care routine you can repeat, then checking the formula and application method against it. These broader factors can help prevent overbuying, confusing concentration with strength, or choosing a product that does not fit your household’s plants.
Match the Application Format to Your Routine
A liquid concentrate is mixed into water, so it fits naturally into a watering day but adds a measuring step. A spray or mist avoids dilution, which can help someone who dislikes handling concentrated products; check the label for how it is meant to be applied rather than assuming leaves and soil are interchangeable. Ready-to-use convenience may mean using more product per application than with a concentrate. If your peace lily is the only houseplant you feed, a small bottle may be easier to store than a multi-plant supply. For a shelf of plants, a general liquid food can reduce the number of products you keep. Choose the format you can apply consistently and according to its directions.
Read the NPK and Ingredient Claims Together
NPK lists the relative amounts of nitrogen, phosphorus, and potassium, but it does not tell the whole story about a fertilizer. A 3-1-2 label, seen on several products here, gives a clearer formula comparison than a product name alone, yet it does not prove that every plant needs the same feeding schedule. Ingredient-focused products such as seaweed and kelp concentrates have a different selling point from conventional all-purpose plant foods. Look for clear label directions and avoid choosing by words like “superfood” without checking what the product contains and how it is used. If you are comparing two similar formulas, application rate and intended use may matter more to your decision than a small difference in bottle size.
Choose Targeted or Multipurpose Feeding
A peace-lily-specific fertilizer is a straightforward choice if you want a product labeled for this plant. A general indoor plant food may make more sense when you maintain a varied collection and prefer fewer bottles. The tradeoff is specialization: a targeted label narrows the intended use, while a multipurpose product may not speak as directly to peace lily care. Do not assume that a plant-specific name makes one formula automatically superior; compare its NPK, directions, and format with the alternatives. If you have only one peace lily, a targeted option can simplify selection. If you care for many houseplants, versatility may outweigh a narrowly tailored label.
Treat Concentration and Bottle Size as Separate Questions
A larger bottle is not necessarily the better fit, and a small concentrate may provide multiple applications when diluted as directed. Check any stated yield alongside the recommended dose rather than comparing fluid ounces alone. Concentrates can reduce storage needs and may suit regular feeding, but inaccurate measuring can lead to applying more than the label calls for. Ready-to-use bottles avoid that step, though they can take up more space as your feeding routine continues. Consider how many plants you will feed and how often the label directs you to apply the product. Buy for your actual routine instead of assuming that the biggest container offers the most practical supply.
Adjust Feeding to Plant Condition and Care
Fertilizer is not a substitute for suitable light, watering, and drainage, so a struggling peace lily may need a care check before a new plant food. Avoid responding to every drooping leaf by increasing fertilizer; excess feeding can create additional problems rather than fixing an unrelated cause. Follow the label’s dilution and frequency directions, especially when switching from one product to another. If you are unsure how the plant responds, begin conservatively within the instructions and watch for changes in growth and leaf condition. Keep a simple note of when you feed so overlapping products do not lead to accidental overapplication. A steady routine is easier to evaluate than frequent product changes.
Frequently Asked Questions
Should I choose a peace-lily-specific fertilizer or a general indoor plant food?
I would choose a targeted formula if you want a product labeled for peace lilies and are buying mainly for that plant. A general indoor food can be more practical when you care for several houseplant types and want to limit the number of products on hand. Compare the listed NPK and directions rather than relying on the product name alone. Neither format removes the need to follow its feeding instructions. The right choice is the one that fits both your plant collection and your preferred routine.
Is a spray or mist a substitute for a liquid fertilizer concentrate?
Not automatically: these formats differ in how the product is applied, and the label should guide whether it is intended for foliage, soil, or another use. A spray or mist can reduce measuring and dilution work, while a concentrate is mixed with water before use. Check application instructions before treating one as a replacement for the other. If you prefer feeding during watering, a liquid concentrate may fit your habit better. If measuring is the main obstacle, a ready-to-use format may be easier to maintain.
Does a 3-1-2 formula mean I can feed my peace lily more often?
No. The NPK ratio describes the relative nutrient amounts in the formula; it does not set a feeding schedule. Follow the specific product’s dilution and frequency directions, since products with the same ratio can have different instructions and formats. More frequent feeding is not automatically better for indoor plants. If you change fertilizers, avoid layering the old and new routines together. Keep track of applications so you can judge the plant’s response without guessing.
How do I compare a concentrated bottle with a ready-to-use bottle?
Compare the label’s dilution rate and stated yield, not just the fluid ounces printed on the container. A concentrate requires measuring and mixing, but can provide multiple batches from a compact bottle. A ready-to-use product skips those steps and may be simpler for occasional feeding, though its bottle can be used up differently. Also check storage space and how many plants you plan to feed. The more convenient option is the one whose instructions you are likely to follow consistently.
Should I fertilize a peace lily that is drooping or growing poorly?
Check watering, drainage, and light before adding fertilizer, because poor growth or drooping can have causes unrelated to nutrient supply. Feeding a stressed plant more often may add another problem instead of addressing the cause. Review the product directions and avoid combining several plant foods. Once basic care is on track, follow a single fertilizer’s label and observe the plant over time. If the condition worsens, reassess the growing conditions rather than increasing the dose.
Conclusion
For most peace lily owners, I recommend Gardenera Peace Lily Liquid Fertilizer Concentrate, 3-1-2, as the best overall because it pairs a targeted formula with a familiar mix-and-feed routine. For best value in versatility, choose Miracle-Gro Indoor Plant Food if you want one product for multiple houseplants; for a premium ingredient-focused pick, consider Gardenera’s Seaweed & Kelp Concentrate. Beginners who want to avoid dilution can look at a ready-to-use spray or mist, while experienced plant owners who prefer measured feeding may favor a concentrate such as Leaves and Soul Professional Peace Lily Fertilizer. For a specific need, pick the format first: spray for less mixing, kelp for an ingredient-led option, or general indoor food for a mixed collection. Whichever you select, follow its label directions and avoid treating fertilizer as a fix for watering or light problems.
