Hi, I currently live in a new build house. The garden has recently been rotorvated and I have subsequently added a layer of well rotted manure on top. I am now in the process of digging this manure in but the soil is extremely hard and difficult to break down in certain areas. I was wondering what the best way forward would be? Do I need to have the ground re rotorvated so that the soil will combine easily with the manure or will this damage the soil? Thank you!
