leylandii topping,how much can they withstand?

[zx6rob]

just looked at a line of 20, 70 or so foot tall trees...how much can they be topped without killing them? i was thinking 20 foot to be safe but they could theoretically withstand half am i right?

Yep, if there is green growth in the bottom half they will be fine, although sometimes the lower growth is much thinner than it looks, and you only realise once the top is gone. Its hard to kill Leylandii though!

 

I usually say one third maximum. Any more than that and you risk ending up woth something wider than it is tall and a real hassle in the future to top again cos the anchor points have gone.

its in a field so the looks arent too important its to prevent windthrow,amazingly they didnt succumb to the winds in the past month!

i shall adopt the '1/3 maximum' rule then,thanks matey

The rule down here from the tree officer! is max 50%, thought that was a bit harsh but hey ho, took ours to about 40% off left 60%. As said hard to kill laylandi unless you remove all gree growth then they get a bit upset.

100% is best.....

Naaaa

 

50% now then another 50% next year, double bubble buddy.

or try the 50% now skin them upto poles next year and sugest growming creeper on them then remove the third year triple wammmie:001_cool:

if look is really not important then 35-50%. but 35% should really be maximum. Also its often more work to do a 50% than it is to fell the lot. Easier work, more clear up often equals the work involved in climbing.

just done a row of 100, 30/40' ers.

 

the farmer wanted to be able to trim both sides and top with his flail. so took em all down to 10'.

 

took us three days and a new set of chipper blades
