I worked in landscaping, most was free solid fill.. Great in some circumstances though, palms love it. I could use a load of fine ground clay in my hydrous hydrophobic soil. Some of the most fertile fields in Ireland were made with the adding of fine layers of clays. It can sometimes have a gold mine if minerals locked inside & gypsum & dolomite are great sources of calcium to help unlock those minerals. I like weak clay dilutions as a soil tonic in dryer soil types. I doubt many bulbs would clay soils too much though.
