Can I compost horse chestnut leaves with brown wiggly lines on them?
Our Advice
This is horse chestnut leaf miner. You can collect and compost the fallen leaves in sealed bags and keep them closed until July, by which time the adult moths will have emerged and died inside the bags. Sprays of Bug Clear Ultra from Scott's or Sprayday Bayer Greenfly Killer'>Greenfly Killer from Bayer are only practical on small trees.
