Curious: If i cut my grass and then IMMEDIATELY Spray WeedKiller afterwards is that bad?

Question

Was wondering....last year when i cut my grass i then followed it up the next day with a weed-killer spray (2-4D) i noticed that my grass started turning yellow. I couldnt figure it out for the longest time and realized oh pooh was the grass in such a weak state (after being cut) that my spraying the herbicide actualyl hurt it even more? Is this true?

Thanks

Answer 1

If it's not a broad leaf specific weedkiller you would have killed the grass anyway

Answer 2

Its because your grass has open wounds in which the sap will draw the herbicide in. Wait 3 days after cutting and then spray.

It would work better if it wasn't cut, as most herbicides are taken in via stomata on the leaf, if you cut off 2/3 of the leaf, then you are playing with a 1/3 chance of killing all the weeds.

Answer 3

you should never use weed killer,that is a very bad chemical.the rain or irrigation washes it into the ground ,and eventually it ends up in the subteranean waters,that some one else may be pumping to drink from.

Sometimes there just is not an easy or lazy way out of doing something correctly and the uggly truth about weeding is that you best do it by hand,i have always done it that way

you use a pointed stick or an icepick or a small garden fork,and you pull out the weeds.leave them where they fall and the organic material covers the now broken ground to stop it from drying out

but this is very theraputic work ,or you hire some kids and you will probable spend the same as the weed killer costs,which is very expensive
,
and you can sleep soundly knowing that you have been environmentally correct

Answer 4

When you cut the grass it leaves the tips of the grass open to the air. If you use a weed killer on the grass while the tips are open like that, it will get absorbed into the blades of grass and this is not good.

Answer 5

I just did this about a week ago, and my grass looks fine. It may just be the kind of grass you have in your yard.

Some grasses that are less hearty will die when sprayed. Check the directions on your weed killer to be sure.

Hope this helps!

Answer 6

Nothing happens to your grass. I did it many times

Answer 7

That would be it. Its best to wait twelve days after mowing before spraying weeds

Answer 8

"And to every beast of the earth, and to every fowl of the air, and to every thing that creepeth upon the earth, wherein there is life, I have given every green herb for meat; and it was so." Genesis 1:30

Don't poison them; don't even cut their grass. They need it to go to seed, and for cover and fodder.
