Transplanting should be done in early spring. Fertilize once or twice per year with a specially formulated fertilizer for Birch trees. Water to keep the soil wet or moist a few inches below the surface. Prune to maintain shape, but do not prune during the growing season. Rather, wait until the end of the growing season in the fall. This is especially important because the bronze birch borer is active during the spring and open pruning wounds are inviting to them.
Resistant to birch leafminer but moderately susceptible to bronze birch borer. The bronze birch borer is the most serious pest to the Yellow Birch, however healthy trees are more resistant.
Iron deficiency may occur, especially in alkaline soils. This is evident by yellowing of the leaves. This problem is refered to as Chlorosis and can be treated by introducing iron tablets into the soil.
