Sprayed mine, watered in.

So I just moved in to a new house. Should I throw down some pre-emergent now, Dec 2nd, or should I just wait until time for the spring application?

For sure wouldn't hurt. You could apply at a 3 month rate then in February do a 6 month rate and that would put you back on a regular schedule.

What kind of turf do you have.

Some type of bermudagrass, with a dense shade rye mixed in at low-sun spots.

Nice. With Bermuda you have plenty of post emergent options for what weeds that have already germinated.

I meant to add. I would do a Prodiamine and Isoxaben app if the budget allows. If I was to go with only one now I would probably go Isoxaben. It's the better for broadleafs and that's typically what you get in winter, besides Poa. Whichever product(s) you decide to go with post it or PM me and I will read the label and tell you what to spread per 1000. It's not hard to do simple math but most people don't and just spread out this and that. Label it the law. LFG!

Apply each separately one on top of each other I assume?

Yes. Never mix them together. Prill sizes are different. Apply each on it's own per 1000. On top of each other is fine, for the most part. Buy a good spreader too.

WTF

Derek, i once called in to a radio show and talked to either Howard Garrett or Neal Sperry about Poa Annua. I think it was the Dirt Doctor.
Till then, i didn't know what it was but had a nice thick patch of Poa that grew along my driveway between the drive and the stepping stones to the porch. It lived there happily for years until my second ex wife decided to pull it up. It used to be pretty and green all winter and kept that spot from being a mudhole. After she pulled it up, it was many years if ever that I could get grass to grow there. So I asked the guy on the radio if he knew where I could get seeds to replant it. He said: "Why in the world would you want seeds!!? That's a weed that most people want to get rid of and go to great lengths to keep it out of their yard!"

Well, I never found seeds but if i could, I'd plant that stuff in a test area out in the back somewhere and see what it would look like as a winter yard grass. It stayed short so you didn't have to mow it in the winter like the rye grass that people plant for winter ground cover. I thought it was a nice pretty green color and grew very thick where it was happy if no one pulled it up by the roots. Around those stepping stones it looked real nice. Am i as crazy as the radio guy acted like for even thinking about this? I'll hang up and listen.

Yes you crazy for wanting Poa. But I understand your reasoning for wanting it. There is dwarf varieties of Rye you could look into. There are even multiple cultivars of Poa. Not sure how well they will grow in your area. I haven't looked into them much. If you want Poa Annua I typically get a few spots in my flower beds that I didn't treat well. I could dig them up and bag them and ship them to you. You could transplant them direct in the ground. Or plant them in a little pot and sit them out where you want them to grow and let it go to seed and die off in spring. Next winter those seeds should germ in that area.

Thanks Derek. That episode I mentioned was going on when I lived in Mesquite. We don't seem to have that particular cultivar out here in the west texas area south of Big Spring. At least I don't recall seeing it.
Kind offer of you to dig some up and pot it for me but I'll probably just let that stay in my memory as how nice it looked by the stepping stones in Mesquite.

Appreciate the offer though! I did learn not to ever plant the damn kind of Rygrass I tried one time in my back yard in Mesquite. That stuff would get about 18" tall if you went out of town for a week or two and didn't stay on it with the mower. Probably could bale hay out of that [censored]. I think that was maybe some kind of perennial rye or some kind of tall [censored] thick bladed rye grass anyway. This year out here what we planted is apparently some kind of thin sort of delicate looking annual rye grass the local nursery recommended. Our farmer buddy says to wait till Feb if we want to see it take off like on steroids. So we'll see how that turns out. Been watering the heck out of it and it sure seems to take a lot of water. The areas it gets extra off a dripping hose timer and runoff from the front porch and sidewalk out front is about twice as high as the rest so I guess we could be needing to water it more! We're on a well and is sure no subsitute for rain water but you gotta do the best you can with what you got and we don't get enough rain to help hardly any at all for grass watering.

We missed our Fall pre-emergent but need to do our winter one to keep those damn burr clover or whatever it's called from making a bumper crop again due to all the excess water its getting now and freakin explode like it did 2 years ago when the spring rains hit it just right. That stuff is like some kind of spawn of satin when you have dogs going in and out. Don't want that again!!

If you want your rye to take off apply some fertilizer to it. I would go with ammonium sulfate at 2.5lbs per 1000sq feet. Then hit it with hose end liquid ironite to get a deeper green color.

If you do have Bur Clover the September app of pre emergent would have been ideal. But no biggie. Feb 1st I would do a 6 month app rate of Prodiamine (Barricade) and Isoxaben (Gallery). Good thing about bur clover is it's a broadleaf weed so there are multiple post emergent options available for you to kill it.

Thanks Derek. Great info as usual. We’ll give that a go.
