  • Sow seed of next year's biennial flowers, such as forget-me-nots (Myosotis sylvatica), sweet William (Dianthus barbatus), and foxglove.
  • Plant spring-flowering bulbs.
  • Dig up tender dahlias, cannas, caladium, and gladiolus before frost hits; store tubers and bulbs in a cool, dry spot.
  • Start spinach and kale under row covers or in a coldframe for tasty winter salads.
  • Still time to patch bare spots in the lawn—cover grass seed lightly with compost.
  • Plant perennials to take advantage of cool weather and rainfall.
