I have the same problem as you 'Anne33'. Our neighbours have 2 of these trees in their garden, which have been there years, and the suckers are coming up through my lawn in several places, but only have been for the past 2 years. They grow really quickly though, as someone stated previously. We are thinking of digging down and around them all, then placing a strong dose of Glyphosate down. Hope this treatment does the trick, as I am leveling my lawn, so have to plant seeds on top of new topsoil. Hope is doesn't ruin the new lawn, or worse still, eventually come through that too. Please someone advise if I am doing the right thing.
Whitean9el, Glyphosate is only effective if sprayed or painted on the leaves. Pouring it into the ground will do absolutely nothing as it is deactivated by contact with soil. The plant needs to absorb it into its tissue and roots through the leaves, so mix it strong and paint it on.
A trowel in the hand is worth a thousand lost under a bush.
We've had a stagshorn for 12 years now. We love it, and when it sends runners out to sprout babies, we carefully did up to grow in pots then give to friends. Our prgeny are growing in Scotland, England, Germany & Austria!
would SBK (stump and brushwood killer by vitax) do the job?
it's formulated not to kill grass and i've used it quite sucsessfully on my false accacia suckers (and the ever present ground elder) that comes up through my grass.
I don't like SBK but it would do the job, it's a broad-leaf killer so can be used where the suckers are coming though grass. But you do need to be careful where it goes, it distorts plants close by for ages after use.
my local 'sells everything shop' has it in stock but i got mine on the interwebs.
i suppose as i'm still in the ground clearance and sucker eradication part of my garden plan i don't have to worry to much about it getting near anything else at the moment.
My neighbour has numerous trees and prunes them every year. He allows all the new ones to come up as well! Does anyone know if the shoots are like to affect the foundations of my house as there have been cracks appearing all over the place in the last couple of years. I have only been here for 4 years.
No they are all definitely staghorn sumach trees that he has allowed to run free in his garden for years and so has 10 or more and it looks like a copse there. Very pretty trees when in leaf.

I have a sumach in a pot, damaged in the winter, cut in town to a couple of inches and now sprouting.

I don't think so LGaynor if Sumach.
If you mean other trees best start a new thread and if possible post pictures of the trees so we know what they are.
