How should I fill my raised garden bed?
Hi, I recently built a raised garden bed with bricks/mortar. The bed is 1 1/2 feet high, 2 feet wide and 12 feet long. The space is empty, and I was about to fill the entire thing with gardening soil, but now I'm not sure if that's the right option. I read on this site to build in layers, after lining the bottom with newspaper, starting with lucerne hay and so on... I'm not sure where to find lucerne hay or the other materials listed. I live in Houston, TX and I'm just trying to figure out what would be the most economical method of filling the bed that will promote vegetable growth to the seeds my wife is wanting to plant?
Thanks for your input!
