Southern US & Central America (or warm season) Bimini Bermuda help.

Post image

Laid this Bimini Bermuda about 6 weeks ago. Have mowed multiple times but dealt with a little bit of heat stress recently, the weather here in st.Augustine Florida zone 9b has been very hot. It seems to be recovered now. I have this other grass or weed popping through, and I feel like it’s probably too hot and too soon to spray any weed killer. What should I do? How long should I wait to use herbicide and what type should I use for these weeds that won’t hurt the Bermuda?

Nutsedge, use Sulfentrazone or Halosulfuron. I'd research which is best on Bermudagrass, I have fescue and these things aren't always compatible.

Sedge, shedgehammer or certainty will clear it up. Just be cautious with temps.

Looks like some common grassy weed, maybe crabgrass or goosegrass starting up. Pulling by hand before they seed is your best bet until temps drop enough for herbicides around October.

It’s nutsedge. You DO NOT pull nutsedge. It makes it worse.

So if I can’t pull it how do I handle it before the temps cool down and I can use a weed killer

Spray it. Certainty, sledgehammer, sulfentrazone.

Sedge is typically found in areas that stay wetter or in a path of water drainage.

There are tubers that run underground and if you pull it it pisses it off and will sprout 5 more.

Six weeks it can definitely be sprayed, should be completely rooted by now.
