Maintenance
Fertilize winter vegetable crops with a top dressing of compost or an evenly-balanced fertilizer.
Start removing and redirecting tired, disease-free summer vegetable plants to the compost pile. Renew vegetable beds with compost to feed the soil for next season.
Dig, divide, and replant overgrown perennials as they finish blooming. Weed beds, add compost, and replant.
Dethatch and aerate lawn.
Pest and disease control
Use row covers to keep cabbage loopers, aphids, and whiteflies from winter vegetable crops.
Keep diseased plants out of compost pile.
Hand pick or vacuum remaining insect pests in the garden.
Look for tomato hornworms early in the morning and at dusk, when they are chomping on plants.
Net grapes from marauding birds. Hanging mylar strips or old CDs to reflect light and startle birds can cut down on fruit loss.
