Hawaiian Umbrella Tree, Arboricola schefflera is a tropical evergreen in the ginseng family (Araliaceae), generally tolerant of bright to moderate light. Principal pests are scales and mealybugs, but also may include aphids, spider mites, and thrips.

The plant responds to adverse conditions (low light, cold or overdampness) by dropping leaves.

If root rot has begun, the symptoms may include withering of the stems from the base toward the tips. Yellowing of the foliage can indicate that fertilization is required.

Some hints about what you might try:

1) Inspect the plant carefully for any of the pests mentioned. If you find evidence of mites or aphids, you will need to take steps to eradicate them, which might include the application of insecticidal soaps or pesticide. If you do spray the plant, be sure to do it outdoors!

2) Determine if the root rot is occurring by easing the entire root ball out of the container and inspecting the condition of the roots. Slimy, fragile roots or a putrid smell are indications that root rot has occurred. The plant will need to be cut back to the point at which they are healthy and repotted in fresh soil.

3) This plant will tend to overgrow its container if left to its own devices. If you have not been practicing any kind of foliage control (trimming back or pinching out new buds) it may have reached a point at which the container is unable to sustain the foliage mass. Skip a week's watering and you are fast on the road to problems.

4) Provide it with the maximum light that you can in your indoor environment. It may be necessary to keep the pot warm with a soil heater if your apartment is cold. You may need to add additional gro-lights and position them closely to the plant to ensure it gets enough light.

5) Find a club, bonsai professional or experienced nurseryman in your area and get a firsthand opinion.
