I have no idea if this is the appropriate forum for this question, but here goes.
I want to plant a new garden in my backyard. I have an area of lawn that a tree fell on, and now the grass there is dead. I've never built a garden in this situation. What's the best way to go about it? Does it need to be a raised garden, or is that optional? If not a raised one, how do I prepare the soil? I know the grass roots have to be ripped out.
I want mostly perennials but some annuals. I keep picturing the finished site as a raised mound covered with wood mulch.
Thanks in advance for any advice!
