Sick tree treatment - aerate the root zone, broadcast ½-1" compost, apply dry molasses or sugar at 5 pounds per 1,000 square feet and lava sand at 80 pounds per 1,000 square feet, mulch with shredded native tree trimmings, and spray foliage at least monthly with Garrett Juice plus garlic tea. Add cornmeal at 20 pounds per 1,000 square feet for additional disease control.
