how can i get rid of crabbgrass and other weeds in my lawn?

Question

places like chemlawn will do the job but cost a fortune since they recommend 4-5 treatments per year at $125 per time. and self-applied fertilizer doesn't seem to do the job....perhaps i'm getting the wrong stuff?

based on some of the answers, i should probably mention that i have 1 1/2 acres to maintain.

i live in ohio....i have a mixture of kentucky blue grass and fescue.

Answer 1

For Crabgrass and other grassy weeds (non-broadleaf) use a product called MSMA. It can be bought in quart size at the local nursery. Also purchase a surfactant, which is is similar to liquid soap (but doesn't foam as much) to add to the mixture, which will increase the chemicals absorption into the undesirable plants. Follow the directions, because the "more-is-better" theory will end up hurting the grass you're trying to keep. For decent crabgrass control, you will have to make three applications, one week apart. Also keep in mind it will take two or three seasons for completecontrol. The MSMA will control several grassy weeds, like grassburs, needlegrass, speargrass, etc. Take the time to identify the undesirables in the lawn.

For broadleaf weed control, look for a spray called 2-4-D. Also add surfactant. This won't work on crabgrass, but will work on clovers, dollarweed, thistles, vines, etc. Again, follow the label.

Your task is not easy...you must be persistent. The more healthy your lawn is, the more chances you have of the healthy lawn choking out the weeds. There are sprays by Otho, OHS and many others that you can apply directly to the infested areas. you can go from weed killers to all vegetation irradiation.
First use a fertilizer that fertilizes and kills weeds. Then use weed killer spray directly on the infested areas. Follow up on the all vegetation killer on what is left. Be prepared to fill in the splotches that are left by digging out the sprayed soil and filling in with weedless pure soil. Seed the new soil or fill in with grass turf.
Very important: Reed the labels of the chemicals you choose and follow the directions exactly.

Answer 3

The trick to killing crab grass is getting it before the weed starts to grow. See the article below.

Corn gluten also suppresses the crabgrass' germination.

Keeping your grass well watered, especially in dry, hot weather will also prevent the crabgrass. Depending on how much you have, if you already have it and it's spreading, you may be too far behind.You might have to pull it up, or kill it will grass killer, then re-sod in the areas where the crabgrass has gotten out of control. If this is the case, it might take you a few years to get the grass back to normal.

Answer 4

There is a product in a bag at Walmart or any store that sells lawn products that you apply to your yard with a spreader that will kill the weeds and crabgrass. Your lawn will turn brown for several days, but eventually all the weeds and crab grass will die. Then you will need to apply fertilizer....this takes time and patience. You must be diligent about it....but, beleive me....it will look better and certainly much cheaper than a lawn service

Answer 5

The choice in chemicals is based on the type of sod or turf that you have. The main grass types are either fescue or cool season grass and bermuda -centipede warm season grasses.

St. Augustine sod grass's great great grandmother was a form of crab grass, so crab killer will do wonders for St. Augustine-not.

A chemical company known as LESCO mixes the weed and grass preventive fertilizers and might be your solution.

I recommend that you make contact with your local cooperative extension service agent-Dept of Agriculture-County-State or US and ask their help. They are the ones who are supposed to know these best and least expensive method to control pests/

Answer 7

Get some of the concentrated broad-leaf spray and a 3 gallon sprayer. The broad-leaf spray is like $8 for a pint and when mixed in the sprayer makes about 15 gallons of spray. Kills the weeds in about 3-4 days and doesn't harm the grass...

Answer 8

Are the weeds green? As long as they don't have thorns and aren't poisonous, leave them alone. Weeds grow where other things won't because they've adapted better to the environment. It's survival of the fittest, dude. Lawns are boring and waste water. Let the plants that nature likes best grow there, and screw the Bermuda!

Answer 9

It doesn't matter how large or small your property is if you want to remove the weeds on the cheap, you"ll have to do it yourself! So, go down to your local hardware store and purchase some weed killer but explain to the people what you need it for and they will sell you what you need. Then after your weeds are dead you can fertilise your lawn without feeding the weeds, common sense!!

Answer 10

You can get the product called weed & feed from your local hardware store or garden center it helped my lawn perfectly and you can look to get the books from Jerry Baker for keeping your lawn tooken care of naturally with household recipes and the stuff he has in his books really work great, by the way Weed & Feed is what I used the 1st time around until I found Jerry Bakers books on taking care of yards to gardens and his recipes really do work for heathy plants and even keeping them Bug & Disease free.
