The vegetable gardening season does not end with the first killing frost. Tomatoes, peppers, eggplants, sweet corn, snap beans and lettuce may have been killed by the first frost. But if you are an avid gardener, kale, collards, peas, cabbage, broccoli, cauliflower, spinach and Brussels sprouts should still be growing.
If you planted Brussels sprouts in late July or early August, you should be cutting off the tops of the plants now to force the sprouts along the stems to increase in size. Cutting off the tops stops the plant from growing taller, thus forcing them to direct their energy into growing larger sprouts.
Follow this practice and your plants will produce nice large sprouts from bottom to top. If the tops are not cut off, you will have small sprouts at the top of the stem and large sprouts at the bottom. Most varieties of Brussels sprouts will be ready to start harvesting just before Thanksgiving.
Peas will continue producing flowers and pods until the plants are killed by temperatures below 28 degrees. Cabbage, broccoli and cauliflower will only exhibit minimum frost damage at those temperatures. Collards, kale and spinach can tolerate even colder temperatures.
If you sowed carrots back in July, your harvest will be sweet and tasty. There is nothing like eating freshly harvested carrots during late fall and winter months. Parsnips sowed in the spring will not be ready to harvest until mid-winter, if the ground has not frozen, or early next spring, when they will be at their best. Steamed, stir-fried or ground and blended with egg and flour, there is nothing tastier than spring-dug parsnips.
The asparagus ferns should by now have all turned brown and be ready to cut, chopped and added to the compost bin. However, avoid composting asparagus plants with red berries clinging to the stems. Those red berries contain seeds that will germinate and quickly become a weed when you spread the compost in your garden.
If you have not already sowed a cover crop of winter rye where tomatoes, peppers, eggplants, lettuce, snap beans grew during the summer, do it now. Winter rye is the most effective plant to absorb available nutrients in the soil, stop the soil from eroding by wind or water, prevent winter weeds from growing and help in keeping your garden soil fertile. Not all of the nutrients you applied as fertilizer or compost have been utilized by the crop you just finished growing. A cover crop will absorb those nutrients, storing them in the roots and leaves.
Next spring when you spade or rototill the rye under, the nutrients will be released back into the soil and used by next season’s crops. The incorporation of the cover crop back into the soil helps maintain the organic matter content of your garden soil. A good garden soil should have an excess of three percent organic matter.
Never allow your soil to remain fallow. Soils that remain fallow contribute to water pollution problems.
