September Gardening Calendar Week 1


  • Continue planting evergreens now.
  • Cuttings of annuals can be taken now to provide vigorous plants for overwintering.
  • Herbs such as parsley, rosemary, chives, thyme and marjoram can be dug from the garden and placed in pots now for growing indoors this winter.


  • Cool-season lawns are best fertilized in fall. Make up to 3 applications between now and December. Do not exceed rates recommended by fertilizer manufacturer.
  • If soils become dry, established lawns should be watered thoroughly to a depth of 4-6 inches.
  • Begin fall seeding or sodding of cool-season grasses. Seedbeds should be raked, dethatched or core-aerified, fertilized and seeded. Keep newly planted lawn areas moist, but not wet.


  • Egyptian (top-setting) onions can be divided and replanted now.
  • Sowing seeds of radish, lettuce, spinach and other greens in a cold frame will prolong fall harvests.


  • Pick pears before they are fully mature. Store in a cool, dark basement to ripen.


  • Autumn is a good time to add manure, compost or leaf mold to garden soils for increasing organic matter content.
  • Monitor plants for spider mite activity. Reduce their numbers by hosing off with a forceful spray of water.
