It's tough to amend clay soil. It takes essentially 1:1 mixing of compost each year to get it to a better consistency. Almost better to build raised beds on top the clay if that's possible for you to do. (and adding sand to clay is actually not a good idea-->you're almost making concrete, lol

Yes, we will be building wicker beds from IBCs for veggies. Okay... mixing in compost! Will be doing that for quite a while I guess!
