Fall is a good time to plant shrubs and trees. This gives them the entire fall and some of the winter to establish a root system, which in turn will give them a better start in the spring. Be careful not to prune plants until after the first frost to avoid soft regrowth that could be killed in the cold.
Plant pansies and mums this month for seasonal color. This is also a good time to divide Iris. To achieve success, you’ll need good drainage, full sun, clean cultivation (weed and grass free) and frequent dividing of large clumps. Geraniums can be overwintered in your garage or basement if the area you are keeping them in stays above freezing. Be sure to bring them in before the first frost. You can leave them in the pots or remove all the soil and place them bare root in paper bags.
Five common flower garden plants–Dahlia, Canna, Caladium, Gladiolus, and Tuberous Begonia–should not overwinter outside. To save the plants, lift roots, tubers, or corms about the time of our first killing frost. They may be dug just after foliage dries. Dig deep enough so that part of the plant will not be snapped off when lifted out of the soil. Leave soil around Dahlia tubers, Canna and Caladium roots. Store bulbs in a garage or other building until soil dries and falls away from plant parts. Shake soil off roots and tubers and cut away dried stem. Immediately discard any plant parts that show soft spots or disease. Place tubers and roots in old sawdust or peat moss—in a flat box or plastic bag with holes for ventilation. Store in a dry, cool place such as a basement. Do not store on back porch or in garage; these plants cannot withstand freezing. Also, store away from danger of being eaten by mice, squirrels, etc.
- Start by thoroughly cleaning plant debris out of the garden. Pull out all annuals that have completed their lifecycle.
- Get your soil tested.
- Add organic matter and turn over soil to decrease insect and disease populations.
- Plant a cover crop of winter rye or annual rye grass to prevent soil erosion and to capture nutrients over the winter.
- It is not uncommon for insects and diseases to be more abundant in the fall. Strive to keep fall vegetables healthy and actively growing; healthy plants are less susceptible to insects and diseases. When sufficient damage is detected, use an approved pesticide.
You can extend the season of tender vegetables by protecting them through the first early frost. In North Carolina, we often enjoy several weeks of good growing conditions after the first frost. The NC Climate Office developed the Climate Thresholds Tool to calculate the average first and last frost dates for your garden. Cover growing beds or rows with burlap or a floating row cover supported by stakes or wire to keep the material from directly touching the plants. Individual plants can be protected by using milk jugs, paper cups or water-holding walls. Most of the semi-hardy and hardy vegetables will require little or no frost protection. Semi-hardy vegetables should be harvested before a heavy freeze. Root crops such as carrots and radishes should be harvested or mulched heavily before a hard freeze. During mild winters, harvest can even continue until spring!
