Hello All

I've just bought 3 Leylandii hedges, & I am aware that they can grow as big
as you let them.

But I wondered how far they should be planted away from my Pond, to ensure
that their roots don't interfere with the lining?

It's not the roots you should be worrying about but the bits that will
fall off it and blow into the water! It's bad enough keeping a path free
of these 'leaves', but they will ruin the water in your pond
