    Not another Lawn Weed Control Thread!

    I did some digging in the old threads, but couldn't find a good answer to my specific question.

    My lawn was doing fine weed-wise until a few weeks ago. The neighbors have a lovely patch where there used to be a tree, but now is a "natural" garden, which loves to spread its natural goodness all over my yard.

    At this time of year, what is the best (if any way) to kill/control weeds on the entire lawn? I can no longer keep up with spot treating. While at the begining things looked good, I lost the battle big time.

    Is it too late in the season?

    Thanks,

    (thinking I should change my forum name)

    Yes. I find it very funny a guy named "herbicide" is starting this thread.

    Just a guess, but I think it's too late in the season to have much chemical effect on weeds. I'd fertilize the lawn and hope the grass chokes out the weeds.

    Re: Not another Lawn Weed Control Thread!

    Sounds like you need a strong dose of Trimec. Trimec is basically 24D and Banvel (Banvel kills clovers which 24d won't do a perma nent kill on.Don't waste your money with stuff at the local hardware store, go to a farm supply/coop. You may have to buy a jug that will last you a few years, but its not diluted down, and you can mix it as strong as you want.

    Just don't get too close to flowers. Flowers and Trimec don't get along very well

    I dont think I would spray 24d and Banvel in town, this time of year. Talk about something that could kill flowers fast, 4 houses down. I dont like spraying those in the country this time of year. I am sure you can go to Menards and find something to solve your problem.

    Re: Not another Lawn Weed Control Thread!

    Depending on how many you have, I've always had good results with Ortho weed b gone for lawns. I mix it up in a 2 gallon sprayer and attack the weeds directly. I live right next to a "nature" preserve and am constantly dealing with all types of odd prairie grasses and clover. I usually spray, give it two weeks, then spray again, that usually gives me about two months of weed free yard. Inevitably, if you have a large weed patch near your yard, they are just going to come back, but that should give you a bit of freedom.

    The key is to make sure you put down the weed and feed fertilizer as well, spring and fall. If you can keep them at bay, it makes life a lot easier.

    Fertilizing now is not the solution. Weeds will love it choke out more of the grass. I'd do the Trimec if you can control the drift.

    Re: Not another Lawn Weed Control Thread!

    2,4D amine from your local co-op will do the trick. As long as you do not use a fine mist spray, it will not drift and kill the flowers. I use it on my yard here in Ames. I use 3 ounces of the herbicide to 1 1/2 gallons of water. It gives me a good weed kill without killing the grass.

    Re: Not another Lawn Weed Control Thread!

    Now is the time of year that crabgrass really takes off since the soil temp is getting to the 70-80 degrees that crabgrass like. If that is your weed, 2-4D or trimec won't touch it. We would have to know what weed it is you are dealing with before we can tell you how to get rid of it.

    By and large if you want a weed free lawn, especially with weed-ridden neighbors, you're probably going to want to treat the entire lawn more than once a year.

    And mow it high so the grass snuffs out any weeds trying to germinate.

    Fertilizing the lawn at this time of year is just fertilizing your weeds. Physiologically, grass plant can do really little with fertilizer. if you want to thicken up your lawn, punt on the 4 step crap and focus your fertilizer in the fall - Sept 1st, October 15th/Nov 1st, for example, weather depending.

    If you really want to thicken it up, aerate around Sept 1st to Sept 15th, put some seeding fertilizer down, seed with a good quality blue grass or the new fescue varieties and spread a thin layer of compost over top all of that. Rake the compost over your lawn, and the rain and watering will move it down - this will give your seed a nice planting base and help keep them moist. If you are planting bluegrass, germination is 30 days, so keep it wet.
