I'm going to put in a raised bed this weekend. My planned dimensions are 16' long, 4' wide and 9" tall. Does that seem ok? As in, is it tall enough to be effective? Also, I'm planning on putting it in my yard, should i remove the sod underneath first? It seems like 9 inches of dirt would effectively kill the grass and make removing it unnecessary.
I live in anchorage and will be growing zucchini tomatoes, peppers beans onions and cucumbers. Hopefully.. This is my first year attempting it.
Any advice is greatly appreciated!
