Does anyone know what approximate ground temps are (north metro) and if it’s time to put down crabgrass preventer?

It could’ve been applied a month ago. The sooner the better for crabgrass prevention.
May 2, 2020 at 8:12 pm #1939445Put it down before the dandelions bloom. Crabgrass germinates when the lilacs bloom.

Not from my understanding. Too early and not as effective. There is an “ideal” time from what I have heard in years past. A month ago we still had snow.
May 2, 2020 at 8:48 pm #1939460You can put Roundup on any time.
Don’t use roundup on your lawn unless you want to kill everything.
May 2, 2020 at 8:55 pm #1939461Don’t use roundup on your lawn unless you want to kill everything.
Sorry I disagree.
Personally we just let the weeds grow. Its better for the bees and our water. Plus you don’t have to mow as much… more time to fish!
May 2, 2020 at 9:09 pm #1939468I’m not using any pre emergents last year or this year. I may not next year too.
I had a lawn service for the last maybe 5 years. I went from exquisite and lushes fluffy green lawn to a desolate desert that was barren. YEP I got pics to prove it.
I’m back to doing my own thing again, what a waste some of the national companies are!

Ok, I guess it might be time for a cocktail so maybe I may once again regress.
May 2, 2020 at 9:39 pm #1939481Greencast shows our 5 day average around 56°. That seems a little higher than it probably is. Are you using prodiamine or dimension?

I’ve typically used Dimension

the month ago comment was just a way to say asap. I’ve always had luck treating it early. Once it’s up and green it’s tough to kill. Just my experience.
May 3, 2020 at 10:05 am #1939533If it wasn`t for crabgrass we would not have a green lawn we are so sandy about the only thing that grows.

Didn’t know they made a grass safe roundup now. I stand corrected.
The original roundup was the one I was thinking of.

My guess is it’s not true Glyphosate. Probably more on the line of 2-4D or another broadleaf herbicide. Just a guess never seen the label.
May 3, 2020 at 4:06 pm #1939571I’d be interested in this as well.
Are you folks using just the straight herbicide? Like this:
Or a fertilizer/herbicide mix? like this:

I’m gonna call the Hugo Feed mill tomorrow and see what they say but I think it’s go-time… wanna get it down before rain this week.

May 4, 2020 at 8:54 am #1939664FYI- Hugo Feed mill is pretty experienced with this I guess. They have a newsletter you can sign up for and they are saying to wait another week based on the cooler temps this week. Again, this is north metro.

This. You can do it with remnant snow on the ground.

For pure crabgrass control yes. However you would likely need to reapply which is a waste of money.
Most all resources say ground temp is important to determine application.
May 4, 2020 at 11:01 am #1939709Try this. You should use crabgrass control when your ground temp is 55 degrees. Water it in.

With dimension it is better to get the timing closer to germination temps since it doesn’t last as long and costs a lot more than prodiamine. Dimension does have some post emergent control of young crabgrass depending on your app rate.
I have had good results with prodiamine. If I recall correctly it ends up being less than $20 an acre to spray prodiamine for 3-4 months of pre emergent control.
