Not all plants grow in soil. There are a huge number of plants that thrive in water. But don’t you need a pond and lots of space to grow them? Not at all!

Plant these in containers of soil and place them on raised shelves or cinder blocks in the water garden so the containers and the first few inches of the plants are underwater.
