Answer: Leaf spots can indicate disease, or poor cultural practices. Until you can positively identify the cause of the problem, you'd be safest to isolate the plant. If the spots or patches are crisp and brown, underwatering is the most likely cause. If the areas are soft and dark brown, overwatering is the probable reason. If the spots are whtie or straw-colored, the trouble is due to watering with cold water, water splashing on the leaves, too much sun, or insect pests. General care for your Schefflera include: cool to average household temperatures (minimum 45F in winter), brightly lit spot away from direct sunshine, liberal water in the spring and summer; water sparingly in winter, and, mist the leaves occasionally. I'd remove the affected leaves. They won't heal, and you'll be removing any potential diseases and keep them from spreading to other healthy plant parts. Try to correct any cultural or environmental causes for the leaf spots, and wait for new leaves to grow. Given the right conditions, your Schefflera will grow 6-8 feet tall.
