My neighbor has this big tree is his backyard, please see the picture. I don't know the name and if you do know please let me know.

I see this plant everywhere in my backyard. Today I realized that the root from his tree is all over my yard and every few feet, a new tree is growing. This is just damaging the lawn and I get rid of it, in one place, they start showing up elsewhere within few days.

Today, I removed like 25 feet of roots from my backyard. I cannot stand them anymore.

How can I get rid of this?

please help. thanks.

Well, what ever kind of sumac it is, probably the best approach would be to take a sharp spade and insert as deeply as possible right at down your lot line near the origin of the tree and sever as many of the invading roots as possibly -- they should only be about 6" deep, so not hard to find and cut. Then, don't mow for a couple of weeks to allow the suckers to grow, and spray with a broadleaved herbicide for lawns. I may take several applications of herbicide to do them in. The best alternative would be to hand-dig the roots, but that, as you no doubt know, is labor intensive.

Wonder whether it'd get back to (& nail) the parent plant in the neighbor's yard, or not?

On the really negative side, round up will probably leave a dead circle in your grass.

But since they spread by suckering, even if you sever the root, it will keep coming back if the parent is alive. Good news is they don't live very long, bad news is your neighbor might start another one from sucker.

It is Sumac, actually it is Staghorn Sumac. Thanks again. At least I know what it is now.

My neighbor is so lazy and he is been allowing these trees to grow. There are 5 big trees and 20 smaller ones in his yard and he is not doing anything about them.

Yesterday, I got weed killer and instead of spraying these suckers, I actually took the root out and inserted the root in the weed killer container. Today, I see three of them already dead in my yard.

I think, I will dig each root and just do that and hopefully they will stop.

if not, then I need to have a word with my neighbor.

Thanks.

Today the oak seedlings from both my and my neighbor's oaks were about four inches high. They are spread all over the front yard. I mowed today. They are all gone. If some have the strength to grow back the mower will get them.

Would it just be easier to mow the little fellas over?

I have two Tiger Eyes Sumac. Their suckers are all over the 20 foot flower bed they are in. Zero suckers are out in the grass three feet away. I blame/credit the mower.

My concern is the neighbor will tell you to remove your maple samaras from his yard. Or the sprouting acorns or something. Be nice, find the words I usually can't.

Sharafi - have you sprayed yours yet? if so, what brand did you use and did it work?

Sharifi, you have my sympathies. I get golden rain trees from my neighbor's yard and am continually mowing, pulling them, and putting tree killer on the seedlings that come up in my yard and beds. Never-ending problem.
