Weeding and Protecting

Keeping your tree out of harm's way

• Weeds and grass compete with trees for water and nutrients.
• They are also alleopathic (they produce a chemical which inhibits other plant growth, including trees).
• Do not use weed trimmers or lawn mowers near the base of trees. Hand-pull weeds instead. When the thin bark of young trees is injured, the bark will split and die back. This can cause disease, unwanted pests, and the sun to scald the bark, resulting in decay or death.
• For optimal tree growth and health, keep a four foot circle around your young tree clear of grass, weeds, or other plant life. Spread mulch in a 4-foot diameter around your tree, 4 inches away from the trunk, and 6 inches deep. The mulch will keep soil temperatures cool, retain water, and discourage weeds.
