Why Is My Sky Pencil Holly Turning Brown – 8 Causes With Perfect Solution
1. Overwatering
If you want to enlist the causes of sky pencil holly browning, I will suggest you start the list with excessive watering. Watering is a major issue for sky pencil holly. If you water more than is necessary, it will stop its internal activities due to root rot.
Again, the uptaking process of water and nutrients will be damaged. Thus, the plant system will remain devastated and later it will be expressed through brown leaves which will end in plants’ death.
Control Measure
Don’t water much of your water. You have to provide a moderate amount when at least 2 inches of the soil gets dry.
2. High Temperature
High temperature is detrimental for sky pencil holly. As sky pencil holly is not a drought-resistant plant, the excessive amount of water stress can make their leaves dry. Dry leaves cannot take part in the photosynthesis process. As a result, they cannot produce food and the leaves become brown due to this reason.
Control Measure
Sky pencil holly loves to grow in moderate temperature which ranges between 55-85°F. Try to maintain such temperature during summer. If you are from a temperate region, bring up this plant as an indoor plant to save you from scorching heat.
3. Dry Wind
The third one is dry wind. Dry wind can harm the plant system more than high temperatures or excessive sunlight. Dry wind removes the amount of air from the microclimate of the plant. As a result, plants transpire more water and make the water level almost zero inside the cell.
In this case, the plant needs more water at the root level to supply the leaves. If there is any shortage of water at the root level, the plant gets dry and the leaves become brown. Sometimes, plants cannot maintain the moisture in the leaves despite the presence of enough water.
Control Measure
Try to maintain the perfect moisture level around the leaves. Water your plant regularly during hot weather. If there is excessive dry wind, you can sprinkle water on the leaves with a sprinkler. (our pick). You may also increase humidity by using a humidifier. (Our Pick)
4. High humidity
High humidity indicates the presence of excessive amounts of water in the air. Sky pencil holly neither survives well in low humidity nor high humidity. Too much humidity hinders the transpiration process. Consequently, the plant cannot remove its extra water which may create fermentation inside the cell constituents.
Thus, the part pigments of the leaves become devastated and the food production gets slower which slows the overall body metabolism.
Control Measure
Remove your plant from such a place where it may get high humidity. The humidity level can be checked by a humidity meter (Our pick). You should keep your plant in warm places like near the windows.
5. Over-fertilization
The next one is the over-fertilization problem that is caused due to using excessive fertilizers which is not necessary for the plant. Sky pencil holly doesn’t need much fertilizer.
Too much fertilizer burns the leaves and internal veins of the plant. That’s why the leaves become brown, having a fire-burnt look. Sometimes, fertilizing methods may also affect them negatively. If you insert fertilizer sticks in the root zone, it will be problematic for the plant.
Control Measure
Sky pencil holly needs fertilizing once a year during spring before the flowering season. You can use liquid fertilizers as they are slow-releasing. They won’t enter the plant body at a time.
You should dilute the fertilizer in the water and then pour it into the plant soil during watering. Don’t fertilize your plant regularly. Otherwise, the beautiful leaves will be brown.
6. Nutrient deficiency
Then, I will talk to you about their nutrient deficiency which is mainly caused due to the absence of iron. Iron is an essential micronutrient that must be present in the plant. If this element is absent along with others, the plant may stunt growth and the leaves become pale and brown.
Control Measure
Fertilize your plant once in spring. The nitrogen, phosphorus and potassium percentage should be balanced inside the plant. You can use organic fertilizers like mustard oil cake and cow dung in your plant. 1 kg of organic fertilizer is enough for a sky pencil holly plant.
7. Pests
Now, come to the point of pests that can destroy the prettiness of your beautifully maintained plant. Insects that affect the sky pencil holly are-
- Spider mites
- Mealybug
- Aphid
- Scale
Let’s have the solutions to these problems.
Control Measure
The easiest way to control these insects is hand-picking. Remove them from the leaves by hand. But you can do this only if they are small in number.
If you see that the insect population is large and tough to pluck by hand, you can use homemade solutions or industrial chemicals to remove them. But If you are in a rush or the materials needed for homemade solutions are not available, you can take an insecticide (Our pick) and spray it on your plant.
If you want to try homemade solutions before using chemicals, then here are some recipes for your convenience-
- Recipe-1: Baking soda solution
Take 4 teaspoons of baking soda in 1 gallon of water. Mix them well and spray them on your plant.
- Recipe-2: Neem oil recipe
Mix 1 teaspoon of concentrated neem oil, ¼ teaspoon of aloe vera powder, a few drops of essential oil and ½ teaspoon of liquid soap into 1 gallon of water. Spray to your plant after mixing them properly.
8. Diseases
Finally, I want to discuss the diseases that may affect sky pencil holly plants. The common diseases are-
- Botryosphaeria canker
- Rhizoctonia aerial blight or web blight
- Leaf spot
- Root rot
To save your plant from these diseases, follow the control measures.
Control Measure
If you get your plant attacked with different diseases, the first thing you need to do is to remove the affected parts of the plant so that the microbes cannot disseminate to other healthy parts.
Then, you can use industrial bactericides or fungicides or homemade recipes as some microorganisms may remain inside the plant without expressing any symptoms. If you want a quick solution, you can use bactericides. Otherwise, you may use a neem oil recipe or baking soda solution as I explained earlier.
How To Save My Sky Pencil Holly?
To save sky pencil holly, you need to be conscious from the very beginning of planting. Planting time, maintenance procedure and fertilizer requirement are crucial factors to save your plant from browning leaves.
Best Time To Plant Sky Pencil Holly
The perfect time for planting sky pencil holly is after the winter period. The immature small plants cannot withstand adverse conditions easily. After the winter, the summer takes a time to come and thus the plant gets its time to prepare itself for the unwanted conditions.
Though sky pencil holly can be planted at any time, you can save your leaves from browning by completing your planting at this time.
Sky Pencil Holly Pruning
Next, you have to do regular pruning of your plant. The matured leaves should be removed. Thus, the new leaves will get more vigorous as the plant doesn’t need to supply food and nutrition in those falling leaves.
Again, pruning helps the inner leaves to be exposed to sunlight which is needed for increasing their food production. That’s why they need pruning.
Fertilizer For Sky Pencil Holly
Fertilizers using mechanisms can also save your plant. Some fertilizers are found in solid stalks. If you use them, you have to insert them far from the root zone. Inserting them in the root may burn the leaves.
So, be conscious of using solid fertilizers. Otherwise, you may use liquid fertilizers which are slow-releasing and beneficial for the plant.
Problems Related To Sky Pencil Holly Turning Brown
Sky pencil holly turning brown may be caused due to different types of reasons. But sometimes, you may get some additional symptoms with this browning which may make you sure of some specific problems.
Sky Pencil Holly Dead Branches
In most cases, sky pencil holly turns brown with dead branches. This problem is mainly caused by fungal attacks. In the first stage, only a few branches get brown and they die after a few days. If you don’t remove those branches, the other branches will be affected and the whole plant will die after some days.
You should spray fungicide or neem oil on your plant after removing the dead branches from the plant.
Sky Pencil Holly Leaves Turning Yellow
Yellow leaves are mainly caused due to viral attacks and underwatering. Viruses stop the production of chlorophyll and hinder the food production processes. As a result, the plant body mechanism is injured and it gets susceptible to any kind of problems.
Underwatering also makes the leaves dry and in absence of enough water, the leaves cannot make enough food for their improvement.
Sky Pencil Holly Crispy Leaves
Again, you may get your sky pencil holly leaves becoming crispy which occurred due to underwatering. When the leaves become excessively dry, the margins become fragile, the leaves become crispy and finally, they fall.
