Finally getting some dirt….
I'm picking up 4 cubic feet of "used organic potting soil" through Freecycle today to put in my new raised bed. The bed is 3'x5' and 1' tall, so obviously I'll ideally need 15 cubic feet of dirt. I think I'm going to break down and buy the other 10 cubic feet at the nursery (rounding down to the nearest even number--it's sold in 2cf bags). I want to get started with this! I'm hoping to get some plants and/or seeds in the ground this weekend. Getting the right dirt kind of worries me, though. How critical is it that I get this right the first time? Is the right dirt the difference between producing and not producing, or is it just the difference of producing a lot or a little? Also, can I get away with less dirt? I'd intended to make the bed 10" tall, but my choices at the lumber yard were 8" and 12" and I went with 12". Now I'm wondering if the edges of the bed will cast shadows if I don't fill it up all the way--living in San Francisco, getting enough sun is one of my biggest concerns. On a happy note, I've just learned that coffee grounds can be used directly in the garden without composting! My boyfriend drinks a lot of coffee, but again with "keeping it simple," I don't want to try my hand at composting just yet.
