What To Do This Month
Apply pre-emergent weed killer to lawn: Pre-emergent herbicides kill weed seeds as they germinate. Some fertilizers contain pre-emergent herbicide. Do not apply them near trees and shrubs or in areas where any seed will be planted.
Watch new growth for aphid infestation: Aphids feed on the undersides of new, tender leaves causing curled, distorted growth. Most broad-spectrum insecticides easily control aphids, but soap solutions are effective as well. Mix 2 tablespoons of liquid dishwashing soap (do not use those containing a degreaser, and use a third less for concentrated soaps) in 1 gallon of water. Forceful sprays of water can dislodge aphids.
Fertilize shrubs: A good lawn fertilizer such as 12-4-8 or 15-5-15 is usually adequate. Shop for a product with 30 percent to 50 percent of the nitrogen in a water-insoluble or slow-release form.
