Use Mulch and Ground Covers
Planting ground-covers and using mulch to fill in your fall beds will make it more difficult for unwanted weeds to establish themselves, helping you to naturally maintain your garden. The ground-cover both smothers potential weeds, blocking out the light,
and helps your current plants by holding in moisture and maintaining a
constant temperature.
You will be working in your garden to remove all of your weeds before planting anything this fall anyway, why not plant something to take up space to help keep them from coming back.
Clean Up the Summers Growth Before Planting for Fall
Removing all of the excess plant material before planting new crops is essential for the success of your fall bulbs, flowers, and vegetables. Annual weeds can be removed with a hoe or by hand. Perennial weeds must be completely dug out to prevent future growth.
