Hello,

I have about 80 foot of gum tree/eucalyptus - if I chop half the height
off,
will it continue to grow upwards okay?

I also have three leylandii which are about 100 foot - if I chop half the
height of these, will they continue to grow okay?

I don't know about the Gumtree but the Letlandi will be back to 100 foot
within the blink of an eye nothing can slow them except chopping down to
ground level and grubbing up the roots -- as you may gather I can't stand
the things.
