Crabgrass - I'm infested

[Prashun Patel]

I live in NJ, and have a crabgrass problem this year. I'm not sure what to do to be crabgrass-free next year. Normally, I just pull out the clumps by hand. But there are too many now.

Should I just keep persistently removing by hand/shovel?

Is there something I could spray?

Should I just let it be and use a pre-germination preventer in the spring ?(like I did this year... )

Any experience or insight appreciated.

If you think about farming, crop rotation is an important part of keeping the land fertile. Growing a lawn is a terrible thing to do to land. However, there are appearances to keep up with, so most of us do it. My personal method is to let whatever grows grow, and not bombard the soil with chemicals. When it gets too high, I cut it. There is freedom in not caring about the green stuff around my property. Just my $.02...

I'm guessing Arnold isn't a top contender for the Garden Club's top award. Again.

I'm with you all the way, but there is a limit at times. Some weeds are just not very attractive in clumps and some starve out everything else making a dead spot.

My neighbor used to use a bulb planter to pop out the offending weed and pop in a plug of good grass from a small replacement stash out back. He worked at a golf course... knew all kinds of tricks. It would take him about 30-60 minutes a month. After a few years he didn't have very many weeds to worry about and he cut his time to about 5 minutes a month.

I would need a plug cutter about the size of Nebraska.

Prashun,
I've had good luck with crab grass pre-emergents in the past. The timing though is the key. If you put it down too long before the soil temps come up it will be gone when the seed germinates, and if you are just a bit late it is useless. DAMHIKS

preemergent herbicides
CrabGrass spreads using seeds.


After application don't use core aeration and don't disturb the soil.
Apply the herbicide right after the forsythia blooms and keep applying it until after the lilacs bloom. Use those plants to inform you when because crab grass seeds sprout at the same time and local conditions may cause those environmental elements leading to the blooms of those plants to vary.

You should not have a lot of weeds if your lawn is healthy -- so concentrate on getting it healthy. Pay a visit to your local county agent. Find out what the fertilizer recommendations are for your area and watering requirements. Do you mow as recommended?

I have around two acres of lawn (various types of weeds). This year is the worst year I have had for crab grass. It has taken over at least 75 % of my lawn. It is so bad that it is even driving out the weeds. I won't do anything about it because the lawn is made up of many types of green things that look okay when I mow it and crab grass is green most of the time.

I have a two acre yard and I have had more crabgrass this year than any year. I use the pre-emergent stuff about every other year. I fight the crabgrass with something like Weed-Be-Gone Max and kill a lot of it. Even with a healthy yard, with very hot weather certain types of the grass in the yard go dormant such as the blue grass and what you have left is the fescue growing. It is important to overseed the yard every couple of yards to keep a variety of grasses growing. Some of them do better in the spring and others better in the heat.

I think that pulling the weeds is a waste of time because you never get all of the roots.

I agree with Arnold & David.....If I were to kill off all my crabgrass and clover I would have only dirt left! (Red clay dirt at that!)

There's a guy on one of the other forums I belong to that lives in Phoenix AZ. and has his whole yard covered in "Field Turf" http://www.fieldturf.com/ ....100% fake and nearly maintenance free and he loves it!

I've thought a many of times about having my whole yard covered in green concrete....

Pre-emergent is the way to go. I usually spread Barricade with a fertilizer down in the winter and it works very well.... well except this year. I normally do this in February. In January, I normally spread Milogranite.

(side note: I once had a golf course chemical sales rep call on me and he was the person who recommended the above tip. He would get his golf course turf managers spreading Milorganite around thanksgiving and come back with a crabgrass-fertilizer application around Christmas. The rationale was GC's don't have much business during those months)

Post emergent herbicides are what you need now. Trimec is an excellent herbicide for crabgrass. Read and follow the instructions... especially the instructions stating do not apply when temperatures are above 85 degrees.

For anyone that has nutsedge growing in their yards, use Sedge Hammer with a spreader sticker. Excellent results.

If you don't want to pull the stuff up, you can put baking soda on it. It will only kill the crab grass. They sell it in 50lb bags at the feed store for a few dollars. Then use the pre-emergent like the others have suggested. This works well for my dad's lawn I like letting the green things grow until they are 8ft high

[Jim Becker]

Prashun, also make sure you're not cutting your grass short...crabgrass and other weeks tend to thrive more when the actual grass is cut less than the recommended 3.5" or so. But yes, you'll need to do the pre-emergent treatment; either with the chemical stuff or, perhaps, corn gluten meal.

I usually follow good lawn practices:

use preemergents 'when the forsythia's about to drop'
don't overfertilize
Aerate every couple years
overseed every couple years
infrequent, deep watering
blah blah.

I'm still overrun. I've always been told to pull any crabgrass that does appear before it goes to seed. There's too much this year.

I dug out as much as I could yesterday. I'll just leave the rest and hope for the best.
