October Garden Calendar

Lawns

  • Mowing heights for bluegrass and tall fescue in the fall is 2 ½ to 3 inches.
  • Core aerate to help loosen heavy clay soils and break down thatch.
  • Fertilize now if not already done so once this fall.
  • Control dandelions, henbit, and chickweed in the fall. Treat as needed.
  • Sharpen the mower blade after every 10 hours of use to get a clean cut.
  • Rake leaves off of lawn as they fall to avoid winter suffocation of turf. Leaves can be relocated to garden beds or tree rings.
  • Mulch mow leaves back into the lawn if leaf debris will not cover the surface.

Flowers

  • Plant tulips, daffodils, and other spring flowering bulbs.
  • Clean up faded annuals.
  • Remove and discard all diseased plants and leaves.
  • Trim perennial stems just below the flower head. Looks tidy while also leaving habitat for overwintering insects.

  • Dig tender bulbs such as gladiolas and cannas. Store in a cool, dry place over the winter.
  • Update your garden journal with successes and failures while fresh in your mind.
  • Take advantage of fall sales and plant new perennials.
  • Divide overgrown perennials.

Trees and Shrubs

  • Wrap the bases of young trees and shrubs to protect them from rabbits and winter sun scald.
  • Rake leaves and compost or use as garden mulch.
  • Remove tree stakes if in place longer than one year.

Vegetables and Fruits

  • Store unused seeds in a cool, dry location.
  • Pick up and discard fallen fruit to reduce disease and insects for next year.
  • Plant garlic in the fall to get a jump over spring-planted garlic.
  • Dig sweet potatoes before the first frost and cure them for 1-2 weeks in a warm location, then store them for winter.
  • Harvest and roast peanuts.

Houseplants

  • Begin long night treatments for poinsettia re-blooming.
  • Check plants for insects and treat them as needed, especially if they were kept outdoors.
  • Wash dust from leaves by placing them in a shower or wiping with a damp, soft cloth.
  • Reduce or stop fertilization over the winter months.
  • Keep plants away from hot and cold drafts of winter.
  • Succulent plants will not need as much water once indoors. Water infrequently.
  • Do not place plants near an open vent, constant hot, dry air will desiccate leaves.

Miscellaneous

  • Spruce up the compost pile for winter by adding new materials, watering pile, and turning it over to promote decomposition.
