Right about now. You can expect to spend 2 or 3 years getting it
under control. Good luck.

Wow! I had no idea that crabgrass was that difficult to deal with.
I will attack the crabgrass today with a 2 gallon sprayer of Acclaim.

Thanks for the helpful info, Stubby.

I apply a pre-emergent crabgrass control in late April here in NJ.
It's been very effective. I usually have a few plants that emerge
anyway, but never any serious problem. If anyone is having problems, I
would check to make sure you're applying it correctly. You need to use
the correct amount and it needs to be applied just before temps get
high enough for germination. Best guide is when forsythias are
blooming, that's the time to apply it. Too late, it won't work because
they are already germinating. Too early, it will have diminished in
effectiveness long before it's needed. I see people applying it here
in March. No wonder it doesn't work!

Using sustainable techniques, least toxic solutions and organic
fertilizers crabgrass CAN be controlled much quicker. The only
crabgrass I have on the 5 acres of lawn I manage is in the area where
I have continued to not regularly top dress with quality compost after
aeration, and continue to use chemical fertilizers at "industry
standard" rates. Go to attra.org and download sustainable turf
documents....

Yes, I did go look at it. To control crabgrass, they have two basic
approaches. One is to cultivate a healthy lawn to begin with through
practices like mowing at the correct height, etc. I agree with that.
It will certainly help eliminate crabgrass and most other weeds. But
in most cases, it's not going to be enough.

The other is to use alternative treatments as pre-emergent control or
weed killer. They suggest corn gluten meal at a rate of 40-65lbs per
1000 sq ft. And they acknowledge it will cost about $1.50/lb. That
means to treat my 10,000 sq ft lawn, I need about 500 lbs at a cost of
$750 per application. Real practical! Then they suggest vinegar as a
herbicide, but quickly point out that is expensive as well. Given
those choices, a bag of conventional pre-emergent applied once in the
spring. followed by spot treating any plants with Aclaim if necessary,
looks like a very sound and reasonable practice.

Thanks for reading, however for some of use the hidden costs of
herbicides are excessive...
