Thatch in St.Augustine grass, got problems


LawnSite Member
A couple of my accounts need thatch removed, thatch is so high now that am cutting at 4.5" to 5.0" to avoid scalping.
The people do not want to pay for the high cost of verticutting and they seem not to understand the problems they will have latter down the line.

Is there another way of removing thatch with chemicals?
And whats the best and fastest way to cleanup after verticutting?

thaxs for the help!
