Lestv said:Sand with clay will turn the soil rock hard if you don't mix in other soil additives too, such as compost. While not true cement, the silica in the sand will form hard plates with the finer particles in the clay after the clay gets saturated with water (a heavy rainstorm).

My garden has the littlest of sand and when it's dry out there's cracks all in the surface like a dried lake. Luckily puddles never form, but all my irises are sitting up about the soil level on very small mounds. Hopefully I'll have some good strong anchor roots to support this. After this spring I never want irises here to sit in a puddle again.
