Exciting times with a new garden Cathie. I must admit, I'm rather enjoying the benefit of having my son at home too. He usually works and socializes 24/7, he's been exemplary at sticking to the rules during lock-down. Amazing how much it helps when it comes to getting the gardening done.
I think if you have light sandy soil it's easy enough to dig it over yourself. And if you don't have light sandy soil, a small rotavator probably won't cut it.
Hire a big one in when this present situation is over or dig it with a spade/fork a little at a time.
let you know how we get on. My garden is large, new to me and frankly a massive project! It's all a bit overwhelming at the moment even though I am an experienced gardener. I was hoping to get help this Spring to get it started but I reckon planting will have to wait until Autumn now.
