Leylandii, Removing

[FredPuli43]

If I take Leylandii down to the ground, will the stump regenerate like some willow or will it die? I am not keen on uprooting several hundred yards of it here. If it will grow back is there some chemical treatment to kill it?

[ferryman]

We had ours. Done to the stumps and they have not grown back.

[murraymints]

It will come back....try drilling stumps and flooding with diesel

[Robinia]

Leylandii don't regrow as a rule.

[ferryman]

We had ours cut down 2 yrs ago and they have not regrown or sprouted anything from them that's definite!

[murraymints]

Mine did...till I drilled them

[Frank97]

If you're concerned you could always use some "stump killer" to prevent it growing back.

[Robinia]

I wouldn't dream of pouring diesel on anything in the garden, it's probably illegal.

[ferryman]

Well it can't be environmental friendly for a start robinia so neither would I.

[FredPuli43]

Must say that I had sycamores and leylandii cut down and the sycamore, predictably, has already shooted from the base but the leylandii haven't yet. But that could be only that the 'cupressus' takes longer to recover. If nothing more than cutting was done, I am cheered by ferryman

Thanks all

Hardly illegal to fill a few holes with diesel..

[heathfield]

Robinia's right - normally they won't grow back. But I removed an old leylandii hedge with 6 x 9" diameter trunks some years back. Of these, one started to regrow, much to my surprise. A few holes and a 50/50 mixture of creosote substitute and paraffin solved the problem.

Don't worry, Leylandii does not grow back from old wood, this is why you see so many leylandii that have died due to them being allowed to get too big before cutting back.

It's pointless trying to kill the stumps, if they are going to die anyway.

What I would do is leave the stumps long, approx 3-4 foot high, then get them winched out, if your in no hurry, they will come out easier, the longer they are left.

Otherwise, hire a stump grinder, to grind them out, if the stumps are low.

We cut ours down and there's been no re-growth
