I've been planning my new garden, once the purchase of the lot next door is complete. I've used raised beds before & plan on making mine out of wood, probably 2x10. I want 4 beds each 4x8 foot each, along with some that are 2x20 along the fence for a bed of blackberries & one for onions/garlic/shallots. The biggest expense is good garden soil for the beds.
