How deep will the clay be softened? I need to go about 3 feet.

I have two 3'x10' areas in which I want to plant bushes and flowers. The

Does anyone have any solutions?

Top dress with compost or leaves. Let the earthworms break up and enrich
the clay. Spare yourself a full planting until next year.
