I would say the best way to remove grass and prepare for planting is to smother it with cardboard and then put the mulch on top of the cardboard. The cardboard will kill the grass and then decompose and add to the soil. Heres what to do:
1. Mow or weed whack the area
2. Wet the ground or cardboard (optional) maybe we can get a big bucket and soak it in the bucket for a few before laying it down 3. Lay the cardboard down starting at the corner of the garden where the first plots will go, be sure to overlap sides so no grass can peek through
4. Put a 6" layer of mulch on top of the cardboard. Cover all the cardboard with mulch.
This is the technique we will use to prepare the grounds at the new Coytown Community Garden. Join us for our next workday on June 25th. More info at www.coytowngarden.com
