Question by star_lite57: what do I add to my garden soil?
I grow veggies in my backyard. When I originally dug the garden, the soil was mostly clay. I added a lot of topsoil to it and grew a summer’s worth of veggies.

The next summer (this summer) the soil was rock hard. I ripped my hands up trying to break up the large chunks of hard topsoil/clay. I don’t want to go through that again next year.

At the end of this summer, is there something I can add to the soil to prevent it from hardening? It has to be safe to grow veggies in.

Thanks in advance.
