September Garden to do List


  • Continue planting your fall garden seeds if you are going to transplant.  Many of your coll weather plants can be seeded directly into the soil later in August.
  • Dianthus, daisies, ornamental cabbages, poppies, nasturtiums, pansies, snapdragons violas, and other cool-weather annuals will provide color for your fall garden
  • Now is a good time to plant perennial herbs
  • Finish your overseeding on turf by the middle to end of the month.
  • If you are planting winter cover crops, now is a good time to be planting your clover, vetch, Austrian winter peas, and other cool-season nitrogen-fixing plants.


  • Continue to foliar feed your plants with compost tea or one of the commercially available organic liquid fertilizers.  Don’t forget the potted plants still in your house.
  • Late in September is a good time to add compost or humus to your landscape.  Don’t forget to add some dry molasses to the compost to feed the bacteria until it gets established.
  • Feed fall-blooming plants with compost tea, either as a foliar spray or with drenching
  • Corn gluten meal should be applied now if it is used as a pre-emergent.  Get it down before the first of the winter weeds seeds start to germinate.


  • For the most part, pruning should now be delayed until your trees and shrubs go dormant for the winter.


  • Turf – Water as needed.  Remember that deep, slow infrequent watering is better than short duration watering on a regular basis.  Turf should only be watered when needed, not on a regular schedule.
  • Water potted plants and landscape plants as needed.  As temperatures warm, potted plants need more water.  Bedding plants may need extra attention as temperatures rise and stay high during the night and evenings.  Make sure to check the soil frequently and water only when needed.

Pests and Diseases

  • Spot spray weeds with 10% horticultural vinegar solution to control weeds. Adding orange oil can help.

Odd Jobs

  • Mow as needed.  Raise your mower as grass thickens.  Leave the clipping to feed the soil.
  • Turn your compost pile
  • Continue to spot spray weeds with a 10% vinegar and water solution
  • Mulch any bare soil in your landscape
  • Feed and water the birds
  • Get your vegetable garden beds ready for winter.  Plant cover crops if you are planning on live cover for the winter.  Get your fall crops planted and make any repairs on irrigation systems and raised beds.
  • Repair and ready your cold frame covers.


  • Till your soil
  • Scalp your yard
  • Spray any synthetic man-made pesticides, herbicides or fertilizer.
