I would think it is time to put down some Pre-em in Houston. You want to target when the soil goes back above 55 degrees. I wouldn't think your area would spend much time below that. I would start with some Prodiamine if you haven't ever done a pre-em. There is not much out there that will prevent nutsedge or torpedograss. I'd use Sulfentrazone on the nutsedge and Quinclorac on the torpedograss. Of course, follow the label on all those products as far as rates go. Ask questions if you need clarification.

 

I am putting mine down this weekend. I'm right outside of Houston. Unfortunately in this area, the ground temp stays above 55 almost all year round. I would just make sure that whenever you start, to stay on top of it. I do prodiamine every 6 months and isoxaben every 4 months. With this, I rarely have but a few weeds pop up every year. Here's a snapshot of ground temps in my yard so far this February. This is taken at a depth of two inches

 

I'm in San Antonio and I put it down Feb 1st

That is amazing. What are you using to mesure the soil temp?

 

Dang. I was gonna wait since I'm near Houston as well, but I gotta get a quick mow in now so I can put down prodiamine before the rains this week

Not sure what tool that is but GreenCast has a soil temperature map as well. Just enter your zip code.

@LittleBearBermuda i have a PWS so that is a probe I have in my front yard in the garden. It's in direct sunlight, nonetheless it's normally within 1-2 degrees of the green cast map online.

I use the Ecowitt PWS. Including the soil moisture probes and temperature probe, I paid about 250 bucks for the whole thing. I have had it for a few years. Now that I know I am into it, I'm hoping to upgrade next year when I move. It's nice to go back and see all the historical data

Very nice. Thank you.

 

There is not much out there that will prevent nutsedge or torpedograss.

Pennant Magnum in April and low rate of Dismiss blanket apps seems to help prevent a lot of sedges from appearing.

Dismiss is what I use to kill it but nothing seems to keep it permanently away.

Yeah I just sprayed pennant Magnum as I have a problem with sedge as well

 

Check the greencast soil temp website for your local soil temps. Look at your 5/10 year averages and apply before it gets to the 55 degree mark, in spring.
Prodiomine WDG.
I wait to fertilize, but I have St Aug, so don't take my fert timing as guidance.

I recently moved to Spring from the Lake Conroe area. When I was up there, I marked Feb 10th as my application window. From the 5/10 year data, the 2/10 date seemed to be right as the soil hovered between 50-55 degrees. The elevation was a few hundred feed higher, so I'm expecting a little warmer soil conditions where I'm at. I applied late on 2/20 (Better late than never), but I'm not too worried because I'll be hitting it with a Celcius app in the spring.

First season problems! I've got some renovations ahead of me.
