Umbrella tree reacts in various ways to cultural problems.
Overwatering causes black new growth, leaf yellowing and drop, or downward cupping of the leaves. If the foliage cups upwards, or has pale coloring in the area between the veins, the plant may not be getting enough light. Odema will cause leaf spotting.
