Finding a Space
When selecting a space for this lush interior foliage plant, it is best to select a spot that provides moderate natural light. Schefflera with its dense foliage needs a significant amount of light to support and maintain all of those leaves.
High light is an option for this plant as well. Be advised that in high light this plant will increase it's water and nutrient usage, and growth will speed up significantly. Attention to periodic pruning will be a necessity in high lighting, and replenishment of nutrient will also be needed to avoid creating a chlorotic plant.
Consistent artificial light is less desirable for Schefflera, since considerably less benefit is delivered to the plant from light sources such as fluorescents. There is often a significant sluffing off of foliage in such situations and the plant can be left with a leggy looking appearance, often desperately reaching for its light source. Though this lighting environment is not ideal it can still work, but expect reaction for some time until the plant stabilizes.
Low light is the is the least desirable situation for Schefflera. In Low light these plants have been known to completely defoliate and ultimately die. An Umbrella tree that begins losing healthy green leaves in mass is most likely signaling that it is not receiving enough light.
Watering Scheff is a simple task if you have been mindful in selecting a space for your plant with good lighting conditions.
In an ideal moderate natural lighting environment, about once a week, your plant will need enough water to moisten the soil through, without excessive water left in the liner. Watering in this manner should allow for the soil to dry out completely in a weeks time before water is reapplied. If the soil is still wet or considerably moist then wait for it to dry out further before watering again. Keeping the soil too moist for too long can cause over watering damage which shows up in Scheff most often as yellow and green mosaic looking leaves that are still well attached.
High light, and or temperatures will increase the productivity of your plant, so in these conditions it is best to water your plant through and leave some excess water in the liner. Allow the soil to dry out completely before watering again.
In lower light conditions, or artificial light conditions, the amount of water should be minimal enough to provide some moisture through the soil. It may also be necessary in such conditions to space watering's out two weeks or more depending, making sure that the soil is allowed to dry out thoroughly between watering's.
Scale & Scheff
Scale is the number one interior plant pest commonly found on Schefflera. The bi-product of Scale referred to as Honey Dew is most often noticed long before the pesky insect itself is detected. Honey Dew is the excrement of the Scale, and is described as looking like sticky dried residue on plant leaves and the surrounding area, similar to what one would see if a soda had been sprayed on something and left to dry. The insect itself looks much like nothing more than a tiny brown bump on the backs of leaves and stems, it can often be mistaken for being part of the plant.
Schefflera should be checked periodically for sign and symptoms of Scale. Treatment can be challenging since schefflera has such dense foliage, it is best to remove as many of the pests as possible by hand wiping. Using a lightly diluted solution of dish soap (1/4 tsp soap to 12 oz water) to both clean, help kill, and coat the leaves of Shefflera is recommended. If the infestation is localized cutting away severely infested areas can be helpful in extinguishing the problem. In sever situations the best choice may be to find systemic pesticide for treating the infestation.
Once lighting and watering have been mastered there are some other things to know, that help to keep your Umbrella tree looking spectacular.
- Regularly remove all dead foliage that has fallen down onto the soil surface. Dead organic material is a primary catalyst in developing a fungus gnat problem, this issue along with over watering are sure to create a fabulous habitat for nasty obnoxious little gnats, so keep the soil clear of debris, you will be happy you did.
- Pruning schefflera from time to time is very healthy. This is a highly active plant so cutting back awkward, leggy, jutting stems back from time to time will keep this plant looking great.
- Remove yellow, or brown leaves. It is natural for highly active densely foliated plants to looses a few leaves here and there, Scheff can be well done by to get a good shake down every now and then releasing and of those dead stragglers that may have gotten trapped inside.
- Rotating this plant just like any other helps to keep an aesthetically pleasing shape, and balanced growth.
Taking into account these tips and techniques will help you to build a healthy long term relationship with your Schefflera.
Questions & Answers
Why are a lot of leaves falling off? The plant no longer looks full.
If the leaves are green that have fallen the two most likely causes are too little light or too much water. If the leaves are yellow or brown that are falling then too little water is likely the problem.
What insect eats the leaves of Schefflera plants, and how do I kill them?
The most common pest infestation found on interior Schefflera plants is Scale. However, the damage done by this pest is not going to show up as visible bites on leaves. If you see actual, visible chunks eaten off the leaves, you might have a larger insect like a grasshopper, or caterpillar which is not very common, but not unheard of, for an interior plant. Since the insects I mentioned are larger, you should be able to find it by closely inspecting the plant, and either kill it or put it outside once it is located.
Can I cut a stem of my umbrella tree and replant it straight in fresh soil or should I put it in water until it re-roots and THEN plant it in soil?
It is best to re-root a Schefflera stem before trying to plant a cutting directly into the soil.
