Cool-season vegetables can provide fresh and nutritious fare throughout the fall months. A break from the sweltering temperatures and decreased disease pressure, due to typically drier conditions, are an added bonus. However, be sure to inspect plants regularly for signs of insect damage as populations have increased throughout the summer.  

Soil preparation is important for fall gardens. Clean the bed of all weeds and any finished plants. Turn the soil with a shovel, fork or mechanical tiller to a depth of at least 8 inches, and cover the tilled soil with 2 to 4 inches of organic matter – leaves, aged manure or compost. This helps maintain a high level of organic matter in the soil, which promotes a strong, healthy root system, improves drainage, retains moisture, provides nutrients and encourages vigorous plant growth.

Rotate plant location in your garden. Rotation reduces insect and disease pressure and allows plants to make better use of available soil nutrients. For example, if you had beans on the row closest to your house during the summer plant them several rows over for the fall.  

Vegetables to seed in August include beets, broccoli, Brussels sprouts, cauliflower, Chinese cabbage, lima beans, mustard greens, snap beans, southern peas, squash and turnips. Shallots may be transplanted in August as well. Wait until September to seed herbs like cilantro and parsley, carrots, radishes and most of your leafy greens. Transplants of cauliflower, broccoli and Brussels sprouts may also be set out in September. Leafy greens excel during cooler temperatures and many can be planted through the month of October.
