honey fungus damage in lilac

Anne McGeough asked 7 years ago

I have a problem each year with my lilac plants, in county Monaghan. The leaves turn brown and curl up and fall off. It appears from previous “Ask Gerry” questions by others that it may be honey fungus damage. What is the treatment for this condition.

Lilac can suffer form long-term honey fungus infection that can cause reduced growth and leaf loss. This can also be caused by waterlogging in winter and damage to the roots. When the leaves come under pressure for water in summer, the root system is inadequate and the tree must lose leaves.

It might be possible to improve drainage of the root area to reduce waterlogging.  

But if it is not that, there is no effective treatment honey fungus.
