Vegetables Remove any remaining flowers from summer vegetable plants.
Tomatoes, squash and melons won't have time to develop before cold weather sets in. By removing the flowers, you will help the plant direct its energy into maturing existing fruits. Use your fingernails or small clippers to snip off blossoms and terminal growth at the ends of vines. When planting time rolls around next spring, all you'll need to do is mow the crops and rototill them into the existing soil. Fava beans, kale and vetch are all excellent cover crops.
