Link?Is your grass Fescue?
If so, there is a fertilizer out there with Tremac. It kills all but Fescue. I use it. Works great
TrimecLink?
Tough to get any real good Herbicides in Ca. I have to ship them to my AZ house. A lot are banned in Ca.I get my pesticides online, do my own pest or something.. They are reasonably priced and helpful. I’m now fighting Bermuda grass.
I’ve got a very funny story about that chemical I can’t tell on a public forum!for a good surfactant use ""Surflan""... its orange in color. not sure if its commercial only. I've applied it on farms...
I have a St Augustine lawn, my gardener uses a 26" 7 blade front throw that he leaves at my house because I'm the only one that requests it, We used to be able to by the Scotts weed and feed for southern lawns, but your 100% right Ca banned it, so I ship it to AZ. and bring it in, It kicks ass and does not screw with the St Augustine (it's so close to the broadleaves your trying to kill) also during the So Cal heat St Augustine will take plenty of water and I also use Ironite through the summer. you can almost hear it grow.Looks like Nut Sedge, Nut Grass, you can remove a stolen and ypu should have the nuts at the bottom like the picture shows.
I've used Atrazine which is not sold in Ca. works fn great. A more readily herbicide would be Manage, which is specific for Sedge grass.
Is there anything that actually kills St. Augustine but not fescue?
