1. Gently aerate ground around Birch tree roots.

2. Apply Di-Syston just before tree is going to leaf out and again 6 weeks later.

3. Work Di-Syston into the soil from about 1 foot from trunk to about the edge of the drip line. Apply at a rate of 1 lb. per inch of trunk diameter (with clump Birch measure largest stem of trunk) measure 6 inches above soil line.

4. Apply a tree fertilizer according to product directions. (such as Ferti-lome tree & shrub food).

5. Keep tree well watered. Birch have very shallow roots and need to be well watered in dry weather.
