Thanks for the info, this really helps.
I am looking to put some under my relatively thin natural layer that resides over domanately weathered limestone. Basically not solid rock but lots of smaller - golf to softball sized rocks. The natural soils seems to range from 3-4 inches to a 2-3 feet before hitting some very hard poor ground.
I am looking to lawn sod an area and wildflower the rest. I was thinking that 2" or so of topsoil under the sod would be ideal. Sound about right?
Regarding sandy loam here in Austin, I talked to a sod dealer and asked about putting top soil. He said most just use the sandy loam and plan on fertilizing it more often. Cheaper than top soil he claims. I am going to call about pricing today but wanted to at least sound like I half way knew what I was buying.
