Raised bed garden

Learn—month by month—the necessary gardening activities for lawns and shrubs, annuals and perennials, fruit and nut trees, and bulbs, roots, and tubers. Included is a timeline for activities such as soil testing, planting, pruning, fertilizing, pruning, mulching, indoor plantings—from cauliflower to okra, from camellias to dahlias to heirloom roses.

Fruits and Nuts

  • New catalogs will be arriving soon.
  • Start plans for future selection and plantings.
  • Take soil test for new planting areas.
  • Fertilize established strawberry plantings.

Shrubs

  • Study landscape to determine plant needs.
  • Check early camellia varieties for damage caused by insects and disease.
  • Replace landscape plants as needed that have severe damage caused by insects, disease, or freezes.
  • After fall growth is completed, spray all shrubs with a fungicide.

Lawns

  • Mow often (5 to 10 days) to remove just 1/3 the grass height at each mowing.
  • If daytime temperatures are consistently cooler than 80 degrees F, apply fire ant bait. Read the label carefully for best control.
  • If winter or spring weeds were a concern this year, apply preemergent herbicides.
  • Reseed tall fescue lawns and fertilize at 1 pound slow-release nitrogen per 1,000 square feet.

Roses

  • Protect fall crops of blossoms from aphids and thrips.
  • Keep plants healthy.

Annuals and Perennials

  • Plant perennials and biennials. This is the last planting time for these.
  • Divide old clumps of perennials.
  • Plant peonies.

Bulbs

  • Plant spring-flowering bulbs late this month in north Alabama.
  • Delay planting in south Alabama.

Miscellaneous

  • Clean up infestations of insects on azaleas, camellias, boxwoods, gardenias, hollies, etc.
  • If oil spray is needed, don’t use in freezing weather.
  • Build a compost bin or box; leaves will be falling soon.
  • Monitor house plants for insects and diseases before moving them indoors. Treat as needed to prevent carrying unwanted pest indoors.
