Conitnuing with the topic of starting a garden in the fall is the choice of materials for your garden beds. The simple solution would be not to use any materials at all, to simply till the soil, ammend the soil and plant. It is a completely viable and very cost effective solution.
I would recommend, however, that you consider using raised beds. Depending on your soil, you can easily spend a lot of time, energy and money ammending your native soil. By selecting raised beds, you can combine your native soil with a more loamy mix, peat, sand and compost to create a plantable bed almost instantly. In addition, by giving the bed more height, you make it easier and more comfortable for you to tend to your garden!
Think about it…and Happy Gardening!
