Seasonal Gardening Tips

Annuals may appear leggy and worn now. These can be cut back hard and fertilized to produce a new flush of bloom.

Roses should receive no further nitrogen fertilizer after August 15th.

Powdery mildew on lilacs is unsightly, but causes no harm and rarely warrants control, though common rose fungicides will prove effective.

Divide bearded iris now. Discard old center sections and borer damaged parts. Replant so tops of rhizomes are just above ground level.

Zoysia lawns can receive their final fertilizer application now.

Apply insecticides now for grub control on lawns being damaged by their activity.

Middle of the month lawns scheduled for renovation this fall should be killed with Roundup. Have soil tested to determine fertility needs.

Sow seeds of beans, beets, spinach and turnips now for the fall garden. Spinach may germinate better if seeds are refrigerated for one week before planting.

Watch for fall webworm activity now.
