I'm a horticulturist in the United States, and I'm interested in converting my lawn to a type of turf that requires less mowing (a mixture of fine and hard fescues). The usual method to accomplish that on this side of the Atlantic is to first kill the existing turf with an application of glyphosate, wait a couple of weeks, and then use a slit seeder to plant the new grass seed right through the dead turf. Howevver, I would like to avoid the use of glyphosate, if possible. I'm wondering if I could simply use a stone burier on the existing turf and then plant right away. Would the buried grass re-emerge to compete with the fescues? Stone buriers are a new kind of technology in the United States and I cannot find anyone who has used them for this purpose. I understand, though, that they have been in use in Britain for some time. Has anyone connected with this forum used a stone burier for lawn renovation?
