Fall Garden Tips for September

Here are some tips to help you prepare your garden for fall.

Nashville, Ark. –

  • Cultivate strawberry beds and make the late summer fertilizer application per your soil test. After the strawberry bed is cleaned and fertilized, mulch around and under strawberries to prevent fall weeds from germinating.
  • Give tomato plants one last feeding. Compost tea, fish emulsion, or usual garden fertilizer should give them the extra energy needed to make that final push at the end of the season. For larger fruited types, pinching off small green tomatoes and any new flowers will channel the plant’s energy into ripening the remaining full-size fruit.
  • Plant transplants of cabbage, cauliflower, broccoli, and Brussels sprouts this month for harvest this early winter. Plant seeds of lettuce, spinach, radish, turnips, etc. later this month and again early to mid-September for fresh greens beyond first frost. 
  • Sow seeds of radish, lettuce, spinach and other greens in a cold frame to prolong fall harvests well after the first frost.
  • Divide and replant Egyptian (top-setting) onions this month.
  • Dig herbs such as parsley, rosemary, chives, thyme and marjoram and place in pots now for growing indoors this winter. Place transplanted plants outdoors in an area with a lot of indirect sunlight and then move indoors in a sunny window in November before frost.
  • Feed mums, asters, and other fall-blooming perennials now for the last time.
  • Divide perennials, especially spring bloomers such as peonies. Peonies are shutting down now and transplanting at this time will allow ample time for roots to get re-established in its new location. Be careful not to plant any deeper than it is growing now. Enrich the soil with peat moss or compost before replanting.
  • Biannual flowers can be sown in early fall for flowering next year. Sow seeds of hollyhocks, foxgloves, sweet William, money plant (lunarian), forget-me-nots (myosotis), purple coneflower, larkspur, and poppies. You can direct sow these where they will flower, or you can start in a seed flat for transplanting later. Better to direct sow the hollyhocks as they are tap-rooted and can be difficult to transplant successfully.
  • Keep deadheading plants such as zinnia and cosmos to ensure that they continue to flower.
  • Take cuttings of coleus this month to provide vigorous plants for overwintering indoors.
  • Lift crowded gladioli when their leaves yellow. Cure in an airy place until dry before husking.
