September Checklist

  • Purchase spring-flowering bulbs while the selection is good.
  • Fertilize most houseplants for the last time until next spring.
  • Sow a new lawn.
  • Core aerate your lawn when the soil is moist but not wet.
  • Autumn is a good time to test the soil in your lawn, vegetable garden, perennial
    bed or around trees and shrubs.
  • Clean off the vegetable garden and annual beds as plants die.
  • Remove spent flowers from perennials.
  • Start a garden debris.
  • Make leaf mould with fallen leaves.
  • Plant some lilies.
  • Plant chrysanthemums, pansies and ornamental cabbages and kales early in the month.
  • Lift and divide iris rhizomes and overgrown peonies.
  • Bring fibrous begonias, coleus and impatiens indoors for potted houseplants.
  • Store surplus seeds in a cool, dry location.
  • Autumn is a good time to plant most trees and shrubs.
  • Don’t fertilize established woody plants until they are dormant.
  • Allow winter squashes, pumpkins and gourds to mature completely on the vine. Harvest them before the first frost. Move perennial plants within the next month or wait until next spring.
  • Make a map of your perennial gardens to record the location of your plants.
  • Continue to weed the gardens. The best place for these plants is in the compost pile.
  • Enjoy your garden!
