Killing trees off

[RickinDarwen]

Hi,
I have a few trees which have sprouted in places where I don't want them, it is not possible to dig them up.
I should have dealt with them when they were smaller but now I find that whatever I do including sawing them to a stump new growth eventually sprouts.

What's the best way of murdering them?

Ta!

Do you know what kind of trees they are? Different ones respond to different treatments!

[RickinDarwen]

I don't know what they are, a couple of pics are below in case anyone can identify them, one is a reasonably fresh one and another more established one which I recently cut all the growth off and sawed the trunk but it is all growing again at the top. (pictured catching a gust of wind!)

Ash!
In many garden centres you will find that the weedkiller section includes 'stump killer' and/or 'brushwood killer'. Those will do the job, but odds are you have a source of seeds nearby, so there will be seedlings next year.........

Our garden is lousy with the things, because at the end of the road there are a few big ash trees which shed seeds galore every autumn!

First picture looks like elder. Second one could be some sort of ornamental cherry - hard to tell. The only way to kill completely as Hilary said, is to saw them right down and use stump killer from the garden centre

Right, i will have a look for that at the garden centre.

We have them popping up all over, it's not too much of a problem except where I took my eye off them for a few years and they are growing out of the brickwork!

Ash and sycamore are among the most prolific seeders, and you don't really notice the little treelets, until they are big enough to be VERY hard to remove!

I would dig them out....stump killer will take ages to get rid of the stump.

Sadly one is growing in a crack between the concrete ground and the brickwork at the back of the house.
It's not a big un, I'll try the stump killer first and see how it goes.

"There are no chemicals available which will rot away a tree stump since wood decay is a natural process requiring time, fungi, insects etc.
Also, many species of tree will form new shoots from its stump and/or roots after it has been felled.
Treating the stump with a herbicide will prevent such regrowth from this part of the tree but may not prevent the formation of suckers from major roots growing further away from the stump" how to kill tree stumps

Simply cutting off the stem can simply promote vigorous new growth ... it's called pruning.
You need to cut the roots, not the stem/trunk.

Or, apply Roundup to the green leaves of the trees and kill it that way. You'll still have to dig out the roots, or let fungi do it the long way.
