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.

Feed mums, asters and other fall-blooming perennials for the last time.

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 by mid-month.

Mid-month cool-season lawns scheduled for renovation this fall should be killed with Roundup now. Have soil tested to determine fertility needs.

Up to mid-month 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.

Protect ripening fruits from birds by covering plants with a netting.

Soak shrubs periodically during dry spells with enough water to moisten the soil to a depth of 8-10 inches.

Once bagworms reach full size, insecticides are ineffective. Pruning off and burning large bags provides better control.
