What to Do in the Garden in October (Warm-Climate US)

The short answer

October is the cool-season garden's big month in zones 7-10. Lettuce, spinach, collards, kale, and root crops all go in now, garlic cloves and onion sets get planted across the Gulf South and Texas, and UF/IFAS calls October the last month to set strawberry plants. Fall is also the South's best tree- and shrub-planting season โ€” roots establish all winter while tops rest.

Two timing tasks anchor the month: apply preemergence control for winter lawn weeds when nighttime temperatures drop to 55-60ยฐF, and start watching for the first frost forecasts at the zone-7 edge. Sow wildflower seed and plant daffodils and other bulbs suited to mild winters.

Plant and sow

  • Direct-sow and transplant the full cool-season roster: lettuce, spinach, collards, kale, mustard, carrots, beets, radishes.
  • Plant garlic cloves and onion sets in the Gulf South, Texas, and low-desert Southwest.
  • Set your last strawberry plants โ€” UF/IFAS calls October the final month for them.
  • Plant trees and shrubs now; fall planting lets roots establish through winter.
  • Sow native wildflower seed (bluebonnets in Texas) and plant narcissus and other mild-winter bulbs; set out pansies and violas late in the month.

Maintain and protect

  • Apply preemergence winter-weed control when nighttime temperatures reach 55-60ยฐF (UF/IFAS timing).
  • Watch for brown patch / large patch in warm-season lawns as nights cool and moisture lingers.
  • Divide crowded spring-blooming perennials while soil is still warm.
  • Keep fall tomatoes covered on the first marginal cold nights to extend the crop.
  • Ease irrigation frequency as temperatures fall, but keep new transplants and trees moist.

Harvest

  • Pick the fall garden's first greens, radishes, and lettuce thinnings.
  • Harvest remaining peppers, eggplant, and fall tomatoes ahead of any frost at the zone-7 edge.
  • Begin picking early satsumas and other early citrus in the Gulf citrus belt as they color up.
  • Finish curing pumpkins, winter squash, and sweet potatoes; dig sweet potatoes before soil chills.
