Prairieville zip shows we're running 3 degrees hotter than the 5 year average for today. Current 78, 5-day average 80.7.

I put mine out yesterday expecting some small on and off rains before any monsoon. My dirt is so dry I expect any light rains to nearly immediately soak in and dry. I'd rather waste a few weeks than miss my window.

It’s definitely a tad early but October is a busy month for me and the least rainy month as well. I got mine done Thursday evening and got .6” of rain today. All dried up in the very dry soil so I’m not too concerned about the rest of the coming rains. My barrier should be sound based on my understanding of how the stuff works with soil

Preemergent and Bifen purchased at lunch. Bifen goes out ahead of the next rain. Will hold off on the preemergent until cooler temps hold a bit.

Same. Put Bifen out a bit ago when it looked like rain…didn’t get a drop. Hopefully tomorrow. Hopefully the bifen helps with the ants that are eating my arse up when I cut grass and army worms so maybe I don’t end up with eggs all over my patio and a half eaten lawn. Ordered the pre-emergent linked here and will put it out when everyone here says the time is right. FYI you can get this pre-emergent for a few dollars cheaper on Amazon and it’s being delivered same day.

I've tried at 4 different ant poisons and am still chasing mounds across the property. This will be my first go with bifen.

Is it a bad idea putting out the pre-emergent today before we get rain from the storm? or still to hot?

Lows in the 60s for a couple days, is it time!?!? Or keep waiting for first real front?

I guess I need a thermometer. On line stuff has my soul temp all over the place. I'll try my food one when I can do it without getting caught.

I went ahead and put out the bag of 0-0-7 crabgrass preventer granules.

I fought a little bit of VBW this year, but nothing like what I see in the rest of my neighborhood.

I went earlier than most. Put mine down a few weeks back ahead of the rain. Current local soil temps show
Current Soil Temperature : 75°
24-Hour Average : 73.9°
5 Day Average : 75.8°

Some of the real pests germinate at 70 so I know I’m covered at least. With 17k feet of grass to water in, I need the rain to effectively get it activated.

Some people I think wait closer to 70. Opinions vary for sure. No harm in doing it now. Sure is beautiful outside

My 24hour average is 68. Will be below 50 for the low tonight . I don't have huge yards, and have sprinkler zones I can activate. No rain coming any time soon

I ran all zones on two consecutive days for 15m each. I hope that was enough.

I wait for 70, but if you tend to have a bunch of winter weeds, I’d do it now.

Reason I wait is so it lasts the whole winter before my spring (late winter, technically) application.

I was trying to push my luck this year and decided to finally jump on it with my soil temps at 73, put down my pre-emergent Saturday afternoon. Checked this morning and they say my area is around 65 degrees.

Now I am questioning my source, have been using the soiltemps website to monitor. Did I time it correctly, or am I only using part of the data and should be looking at other sources?

You’re fine. Seeds begin to germinate under ideal conditions, a few hour spike below 70 won’t trigger a massive germination. It’s better to be early than late.

You should look at the 24 hour average soil temp, if the average hits 70 or below for 3 straight days, that’s when you should start worrying that you missed the window.
