Pick Hornworms


Check tomato plants for these large green striped caterpillars. A few can cause much damage, so hand pick and destroy them when found. Spray B.t. (Bacillus thuriengensis) to control large infestations.

Plant Buckwheat


In areas of the vegetable garden that are finished producing, plant a cover crop such as buckwheat now. Buckwheat not only grows fast, it provides organic matter to the soil when tilled under and smoothers other weeds.

Stop Pruning


Stop pruning trees and shrubs now. Any pruning done after July will result in young growth being stimulated to grow. This growth won't have time to harden off before cold weather arrives and will result in winter injury to the plant.

Control Scale

Check the undersides of leaves on euonymous plants for white flecks. These could be scale insects that are sucking plant juices. Control euonymous scale by spraying a horticultural oil or insecticidal soap on the plant. Prune off severely infected branches.

Take Geranium Cuttings

Take cutting of geraniums, coleus, and begonias to produce new plants. Take a 4- to 6-inch-long cutting, dip the cut end in rooting hormone powder, and stick the cutting in moistened potting soil. Cover with a clear plastic bag with slits in it and keep out of direct sun. It should root within a month.
