Clay soil, digging it out
Hi, I have spent ages looking up what to do with my problem but can not find a solution for various reasons. I recently laid turf and didn't compact it so lifted it all up again. By doing this I noticed a lot of water being held. In this one problem area I have clay soil which is causing me problems with drainage. Before I lay the turf I intend to do the following: Dig out all the clay soil Drill large holes in the ground every 5 cm Add a 5cm layer of sharp sand Fill the rest with top soil Is that a good idea? How far should I dig down?
