Raised pond surrounded by a raised garden bed. The plants will shade the pond from the hot summer sun, you can raise tilapia or just a small goldfish pond. Would look great next to the patio/deck or among the raised garden boxes
Lay down a thick layer of CARDBOARD in your raised garden beds to kill the grass. It is perfectly safe to use and will fully decompose, but not before killing any grass below it. Theyll also provide compost and food for worms.
