Dateline: Central Texas
So late last year laid down a palate of St. Augustine over existing weeds (getting nasty) and Bermuda (weakening). Watered twice a day for two weeks and seems to have taken hold. Looked great for five or six weeks then winter hit and it went dormant. Seen more broadleaf weeds then in previous years. I've been warned that pre-emergent on this new lawn was unwise, so I didn't do any. Same for spraying for broadleaf.
But I'm wondering, since most of the grass blades are dead, is a broadleaf spray gonna hurt anything? The one someone gave me is made by roundup, actually - not the traditional kill-everything Roundup. I suppose there's a case to be made for the broadleaf killer to affect the St. Augustine roots. (I'm seeing some green blades, already).
So what's the verdict from Surly's Lawncare Gurus on the broadleaf treatment?
And while we're at it, I did put down pre-emergent on my existing Bermuda sections a couple of weeks ago. I think I got that in under the wire, but what say you on using it now (on a friend's yard) which will soon be sodded. Is it too late?
And by the way, I'm catching a lot of flack for not watering enough during the winter. Seems to me it was a fairly wet winter. And if the ground is so fucking dry, why the hell is all this broadleaf coming up.
Thanks in advance.
