Lawns: is it too late for crabgrass preventor?

[Aquabach]

I've been real busy with the house and my Mom so i forgot to put crabgrass preventor down.
Is it still early enough to do or would it be a waste of time & money?

If I can still do it can I also put weed & feed down soon afterwards?

[Paté]

My guy just put it down the end of last week.

Still time but get it done .... You want it done now to benefit from the cooler weather, once the heat comes you risk burning the grass . This right now is the perfect growing season .

[DrBrianDDS]

I'm doing mine tomorrow hopefully. Little late, but I think we are still good to go

[Strat688]

You have until mid-may,,,,'so it's close

I believe the general rule of thumb is to space application of any products containing fertilizer about 6 weeks apart.

If you say apply Scotts Turf Builder with Halts now, you'll need to wait about 6 weeks before applying the Scotts Turf Builder Weed & Feed.

Use one or the other not both .... Fertilizer then herbicide

[Shamuscull]

It's all a fucking scam.

[Southshorerob]

It's actually cool when done right , aeration , feed (fertilizer) than herbicide (broadleaf,clover) water ,water, water

[BLAMMO!!]

No it's not too late. You might even have another week or two. The soil hasn't warmed up enough for the seeds to germinate.

Use Preen with Dimension. It will also kill post-emergent plants out to three weeks. Well, that's what the bag says anyway.

I usually put it down 2x. I found that if I only put it down in mid to late April, it was not covering me through August. With a second application mid to late May, I was GTG. So you are fine.

[METALHEAD]

It's all a fucking scam.

Agreed....best crabgrass preventer is a thick healthy lawn. Seed , fertilize, water and kill weeds. Scott's did nothing good for my lawn but that also may just my way of justifying paying 10 bucks for a bag of 10-10-10 vs a $50 bag of Scott's.

I also do the same it seams to get all the late germinating crabgrass.

It might be a little late but i'd certainly still put it down. I read somewhere a while back that the best guide is the yellow flowers on forsythia bushes. Put the crabgrass preventer down just as they start to fall off. It's either that or monitor soil temps like a real weirdo. I've been using the yellow flower rule since I bought my house in 2013 and the lawn keeps getting better.

I feed and/or weed 5 times. Crabgrass in early spring, weed/feed late spring, summer guard mid July, then the fall/winter stuff usually first week of September and once just around thanksgiving after the leaves have fallen and everything is cleaned up for winter.

Exactly...you still have a couple of weeks especially with how cool it's been...one issue is make sure you buy it now because once it's gone the stores don't restock it.

[DeathDealer]

After the forsythia blooms ,before the lilacs

[BLAMMO!!]

I used to apply it in early April because that's what "they" always tell you. I lrearned that's a waste because you have to do another app in June, otherwise you'll get crabgrass later on. Now I do it around the 3rd week in May or even Memorial Day (depending on the temp) and that's the only application I do. Even if I get one or two spots of crabgrass in August or September I don't get to bent.out of shape.

But yeah, I better get the stuff by this weekend or it'll be almost impossible to find.
