The Young's Weeping Birch is a variety of European white birch. This tree's characteristic asymmetric branch structure makes it an interesting addition to small garden areas. 

Plant Needs
Zone: 3 to 9
Light: Full sun to light shade
Moisture: requires consistently moist soil, water regularly
Soil Type: Moist, well-drained, neutral

Care
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.

Problems
Susceptible to birch leafminer and highly susceptible to bronze birch borer.

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.
