I had a very large tree, I believe it was an oak tree, that was taken down last summer. These green weeds are growing throughout my front lawn and have very thick roots. If I don't pluck them they will grow to be very thick and need to be dug up and cut with large clippers. Now, I believe they are growing from the old roots underneath the ground. Any chemical that can stop the growth? I will need to do a lot of digging afterwards to get these small roots out of the ground but I really need to stop them. I'm at my wit's end right now.

Thank you for the help in advance.

Following because I've got the same issue with a tree I cut down earlier this year and the same thing has happened to me. I'm hoping I don't have to dig up all those roots because they're all over the yard.

There is a herbicide that is supposed to work on these, but only if the tree is gone or you are willing to let it die. You drill a hole in the base/root and pour the chemical into it. Unfortunately, I don't remember what the herbicide is. If I can find it I will post accordingly. @Greendoc probably knows off the top of his head though.

I appreciate it. I will look into it. The tree was removed and the stump grinded. Hopefully if someone else has additional information that would be great!

The tree is suckering from roots that were not affected by the stump grinding. A herbicide containing Triclopyr may kill the remaining tree. I am fond of a product available in small quantities sold as Crossbow. This is a combination of 2,4-D and Triclopyr specifically made to kill trees. Cut off the sprouts and apply the product to the cut surface. This is one of the best things to apply to a tree after it has been cut down so it does not do things like this.

@Greendoc is an encyclopedia of knowledge. Thanks for your input in just about every thread. You have really helped me out as well. Appreciate it!

I found the Crossbow product that contains those ingredients and mentions it's for weed and brush. I just want to be sure I'm using it correctly before I kill my grass. As in my 3rd picture, is that short enough to spray on top of? Or should I cut it shorter?

Thank you very much!

 

[Greendoc]

In this case, you do not spray it. It is to be brushed onto the cut ends of the sprouts. How you cut it is short enough.

Ok, thanks a lot for your help. I will try and post back in a few weeks and let everyone know how well this works.
