I'm trying out this no-till technique this year for the garden.
(www.backtoedenfilm.com)https://www.backtoedenfilm.com/It keeps the weeds out and reduces the need for watering.
I put down a 30'x30' tarp over the winter to kill the grass. Then I put 4 inches of compost down and 4 inches of cedar mulch over that. I got the mulch from a tree service for free, they sometimes have trouble finding places to dump their tree trimmings so if you call one you can get it. I got the garden out a bit late but it is growing well right now. I'll let you know how it goes.
From the website:
BACK TO EDEN is a documentary about American gardener and arborist Paul Gautschi. Back to Eden is a no-dig gardening method that practices organic growing principles. The sustainable permaculture technique is simply to apply wood chips on the surface of soil to conserve water and regenerate the soil.
