Leylandii Trouble

Mrjones130

Good Morning, I was wondering if anyone could offer me advise on a problem I am having with one of my Leylandii.

We recently had our garden landscaped and had a small wall built along the front of our leylandii hedge. The first leylandii in the row had to have one of it's major roots cut, in order to lay the foundation. Since this was done, this particular leylandii seems to have been shocked and has turned visibly yellow, whereas the rest of the hedge is a healthy green. The tree isn't browning but definitely doesn't look healthy.

I have tried watering the tree but this hasn't helped and I wondered if anyone had any suggestions on how to bring the tree back to full health.

Thank you.

They talked about something similar to this on Radio Ulster Gardening Programme this morning,  he recommended putting microrhyzal fungi in at the roots and a heavy mulch manure round it. You should be able to get it on iplayer "Gardeners Corner"
