It can be helpful to have someone else come in and do some work on your gardens! I’ll bet there are local folks who hire out as gardeners. Ask your friends or look in local stores on notice boards. I’ve had someone help with projects and especially in the spring. It’s made a big difference.
I am a beginner gardener. A lot of what I’ve done in the garden is remove bad things from the previous owners, and plunk in trees and plants. I really want a plan!
