Pre emegent ?

[Yellowstang]

OK, so I got a bag of Scott's pre emergent and read the insdtructions, but it nevers says if I need to water the lawn afterwards to help it reach the soil and break down. Closest thing to anything about water is "Apply on dry grass".

So do I just let it sit as is, and let nature break it down, or give the sprinklers a few minutes on each zone?

[zemog]

water it in

[MrEd]

i already started a thread on this subject,and rumor has it your to late with the pre-emergent.

and rumor is just that, look at my other post

[zemog]

just finished up all my customers lawns last week,and i will be applying pre emerge to my golf course this week and again in 8 weeks

[MrEd]

Pre emergent herbicides are generally only effective if applied before the annual grass weeds emerge. Therefore, early spring applications are essential if satisfactory weed control is to be achieved.
they have already emerged.

So is it too damn late to put out corn glutten meal????

[zemog]

yeah seen a bunch of crab and goose grass, nutgrass....no
maybe you should of seen sundays paper with neal speary's advise of pre now and again in 8 weeks.
oh and smart guy, there is a difference between broadleaf (which are what you see now) and grassy weeds which typically emerge when soil temp. is at or around 59 degrees.
i do this for a living , i dont just make up shit that i have read or hear and i am in my 15th year in this business.

I just got some nut grass in a few spots....don't know whether to throw down the corn glutten meal or do the bradfield organic.....

[zemog]

never ever seen nutgrass this time of year and i am not a fan of the natural fert. programs, i have had to take over several landscapes to get them back right that were on it. not saying you are wrong (ok maybe i am) but i really doubt you have nutgrass unless you are in the deep south.

nutsage is a good nutgrass killer, if and when you get it.

Some weeds germinate in the fall. This is why it needs to go down then.

Shit, in Texas weeds gorw 24x7x365! Doesn't matter what the temp is, if they get water or not, they fricken grow!

I got some Scott's fertilizer with the pre emergent in it, I will put it out next weekend or the weekend after that.

Sorry the name of the herbicide is manage not nutsage, nutsage is another name for nutgrass, sorry for the misinformation.

Here's the answer straight from the horses mouth (neil sperry). Of course, we here in texas call the spring and summer treatments "weed and feed". The fall treatment is the one that people forget because the grass is dormant and it appears that nothing is happening, when in fact is is very important because there are some weeds that germinate around then.

Q. When should I apply pre-emergent weed killers in the fall and spring?

A. The fall application should be made the first week of September. Use a Gallery product for broad-leaved weeds and Balan, Betasan, Team or Dimension for grassy weeds. You'll want two applications in spring and summer. Both spring treatments should be of the products for grassy weeds. The first should come in very early March, and the other should be 90 days later, in early June.

hmm, reference post 5, with the warm temps i wouldnt wait till march if it keeps up like its going you'll be in trouble (well hell i guess it is nearly march, nevermind):biggrin:

That reminds me, I need to apply weed and feed this weekend :boobies:

Neils's article in last weeks paper said not to apply weed and feed yet ,just pre-emergent this early ...

[zemog]

you can it just takes a little longer with cooler soil temps

I have not put a thing down and I already have some weeds everywhere. I guess it is too late to put anything down to do any good, huh?

No, do some pre emergent now, it will not do anything to growing weeds, but it will help prevent some later this spring/summer. Wait another 6 to 8 weeks after you use the pre emergent, then do a fertilizer/weed killer combo.

I have some stupid weeds too, I got the liquid weed killer that attaches to the garden hose and zapped a bunch, but some new ones are coming up again. They are not a broadleaf weed, so the pre emergent will not prevent them from sprouting up.

What yellowstang said. You can't stop them from germinating now, but you can fight back with weed and feed and spray weed killer.

[Red 342 H.O.]

I don't use weed and feed. I believe it kills shrubs and trees. I will probably go get some corn glutten meal and throw it down this week.

[Mustangman_2000]

What brand of weed and feed is everyone using? And has anyone figured out how to get rid of Thistles? Those things are the bane of my existence.
