Build a pyramid planter for your strawberries. Each hole in the concrete block will hold more than enough soil for a strawberry plant. Wooden pyramid options I've seen waste too much soil under unused space. Once the plants grow in.
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
vertical garden - "perfect for herbs - this makes more sens than the tower I was planning - add a grow light and place in your garage during the winter - build with bottom and put wheels on it for moveability" Nice idea!
Trellis between two raised beds increases your growing space and creates shade! Grow lettuce & other plants that need afternoon shade under the trellis. Position beds so that the shaded plants receive morning sun.
