Our plot is on clay. Early this year, when it was very wet and muddy, the plot was dug up to install a sewer so we had to start from scratch!
We bought in a lot of mushroom compost to neutralise the clay, and laid about 50mm of mulch.
When I tried to trowel holes for lettuce the clay was still too hard.
***brainwave*** I used a robust bulb planter to take out long plugs then filled each hole with a mix of peat free compost, molehill earth and spent garden compost – no particular ratio!
The results have been very good, lettuce, and other plants are doing very well.
