Can I re-vitalise an old lilac tree ?
It's a white lilac and looks stunning in full blossom. Over 20 years old and about 9 feet tall. Problem is the leaves and flowers start at least 7 feet up, with bare branches lower down - the main trunk, a secondary trunk and several more "bendy" branches. I've got a small garden and at the mo the tree doesn't "pay it's way".
My question is can I cut it right back to a couple of feet (it would be bare of leaves) and will it re-generate ? If I cut it back by less it will still be bare but look ugly !
Or should I bite the bullet and remove it ?
