LAS CRUCES -- Home gardeners and growers are hurrying to harvest the last of their fall crops this month before first frost.

Mature green tomatoes can be ripened in the house and blankets can be thrown over other warm-season crops for short-term protection.

Other crops are more tolerant of frost.

"The taste of cabbage will actually improve with a light frost," said George Dickerson, horticulture specialist with New Mexico State University's Cooperative Extension Service. "Cool weather retards respiration in the cabbage and allows sugars to accumulate, resulting in higher quality. Cauliflower and broccoli will tolerate light frost. Kale is extremely hardy."

Cool weather also will improve the taste of parsnips stored in the soil. Turnips and radishes will tolerate cold weather for several weeks if left undisturbed in the ground.

"Unless you have an infestation of wireworms or grubs, potato tubers can be stored in the soil all winter if properly mulched," Dickerson said. "After removing the plant tops, place a layer of straw over the potato beds at least 8 to 10 inches deep, anchoring it with bricks. This will keep the soil from freezing. Potatoes can be harvested as needed throughout the winter."

Winter squashes will tolerate light frosts but should be removed from the garden before severe cold weather sets in. Dry beans need to be gathered before they shatter. Other crops that tolerate light frosts include spinach, leaf lettuce, carrots, fall peas and fava beans.
