What is leaf miner and what should I do if my horse chestnut tree has it?
The horse chestnut leaf miner burrows into the leaves of horse chestnut trees. The leaves get brown blotches on them and eventually shrivel. These damaged leaves often fall long before the shedding of leaves in Autumn.
If you come across any trees you may suspect have leaf miner moth, it would be best to contact the research department of the Forestry Commission, as they are monitoring the spread of this pest. Their contact details are:
