Birch -- Yellow Leaves

Yellow leaves on birch trees can be a sign of several problems:

1. Lack of moisture. Birches are shallow rooted trees and require anywhere from 1 to 3 inches of water per week depending on soil types (more on sandy, less on clay) and temperatures (more during hot weather, less in cool periods).

2. Iron chlorosis. Birches require a slightly acidic soil. Check the pH level; ideally birches thrive between 5.5 and 6.5.
