Has anyone ever tried square foot gardening? I am going to give this method a try because the soil in my area of South Central Pennsylvania is horrible. It is hard, rocky, and almost impossible to dig so I thought maybe this method would work much, much better for me. I have read that you should use a dirtless mixture of equal parts of sphagnum peat moss, vermiculite, and compost. Does this type of "soil" work well for vegetable gardening and can I use it to plant berries (blueberries, strawberries, raspberries)? Also, is it better to use the vermiculite of perlite...or a combination of both? I have not had much success with gardening in the past so I am hopeful that this method will allow me freedom to grow bigger and healthier crops. Any help would be greatly appreciated!
