Our garden has six raised beds. The walls are 30 inches tall and filled with a mix of 2 parts topsoil, 1 part peat moss, and 1 part composted cow manure. We’ve also amended the ground surrounding the beds. We try to position taller plants on the ground and shorter ones in the elevated beds to avoid bending over. A few compost bins around the garden allow us to make our own compost to continually replenish the soil for free. Besides needing six to eight hours of sunlight, most herbs and veggies require well-drained soil. Fertile soil will produce healthier, more flavorful plants.
