I have recently dug a number of post holes in order to erect trellis. After the first few inches of soil I hit clay which I put into a number of bags as it was unsuitable for refilling the post holes, being very lumpy. With the recent sunny weather, I put some of these lumps in a wheelbarrow to dry them out and then crushed and sieved them, leaving me with a bag of clay particles from orange pip size down to dust. What is the best use of this material, the post holes having already been filled with topsoil and pea shingle? I estimate I would end up with 75l if I crush the rest.
