I've just had my laylandii hedge cut down to ground level as it was almost dead. The people who cut it down for me told me to get some root killer from B&Q/garden centre etc.

When I went to the garden centre yesterday they told me that, once a laylandii is cut down, it will die off naturally and I don't need to put anything on the stumps to kill them.

Is this correct? Any advice would be gratefully received.

    I'd be inclined to think you wouldn't need anything Nora when you bear in mind that cutting back into them kills them off. No point buying root killer if it's not necessary but someone else may know differently! You might want to get the stumps out if you want to plant something else (which could be hard work) unless you can work round them, and the soil would need a fair bit rejuvenation with manure/feed/water to get some life back into it before planting anything else. If you can raise the area a bit it would make it easier.

    They will die off but they will take an age to do it! Like FG says if you want to plant you will need to speed them on their way. You can hire a stump grinder if you can get it to them otherwise drill big holes in all of them, as many as you can be bothered with and fill with soil. Will get the wood eaters in there and rain water to make them rot. Works better than any root killer image

    Yes, you don't need to kill of the stumps, they will not re-shoot.  image

    However, as Fairygirl says, if you want to replant you will have to have them ground out - the soil will also have been very impoverished and will need nurturing.

    Hi Nora, I had 18 of those trees, planted 2ft apart and way taller than the house, in my garden when I moved here. I cut them down but I left nearly 5ft stumps. They were like that for a year until my son grew big enough to push them out and dig (like pulling teeth). I had problems with the soil for a couple of years until I got some goodness back into it. I had just started gardening then and I now realise why subsequent plants were dying. The llandii had sucked every bit of goodness out of the soil.

    Haisie - sounds like your son grew very big and strong quite quickly- whatever do you feed him on, Fish Blood and Bone??? image 

    I think you could hire him out on this Board image

    We have just removed a L- hedge - and had the stumps ground out.  Our next step will be to dig in as much horse manure as we can this autumn and next spring - hope that will do the trick. The plan is to grow veg there eventually.

    I have dug out leylandii stumps using a pick, an old axe and a spade. It really helps if there is some trunk left to use as a lever, but you seem to have been left with ground zero.

    They really aren't that difficult to dig out as the roots are not very deep (hence their ability to drain the soil dry).

    If a midget-sized female pensioner can do it, anyone can.

  • Thank you all very much for the replies.

    I've got just a few inches of stump above the ground. I'd like to plant something else there eventually but am also toying with the idea of a low fence - I'm not one of life's little gardeners and anything that doesn't need attention (except for a slap of creosote every so often) really appeals to me! In the meantime, I've got montbretia (spelling?) to stop the edge of the garden looking too bare.

    All in all, it looks as though I have a year or so to decide what to do though.

    Thanks again for the help.



  • I'd like to say I'm big and strong!! I might have a go - maybe when the weather cools down a bit because I think I've got about a dozen to get rid of!
