How do I go about improving soil in my garden?
Currently it is a large flower bed with 2 inch mulch of cedar chips. How and with what should I amend the soil? Do I need to remove the bark chips first or can I just mix everything into my soil? How deep should I dig it in? Will all this digging around the roots hurt my plants? Have good intentions but don't want to mess this up!
Thanks so much for any and all advise!
Payson Arizona. Topsoil has been amended years ago and I think it drains too fast. The subsoil, about 20 inches down is clay.
