Does this look a familiar sight to you this autumn?The sunshine tempted me out for a long walk yesterday but I was struck by the extent of the damage to the horse chestnut trees in the South East. Even from a distance it’s clear that many of them are dying and certainly I hadn’t taken on board just how many have been affected in this area. In fact we did not see one healthy specimen all day.
It seems that our poor horse chestnuts are being hit by a double whammy; many are infected by a bleeding canker which scientists have now identified as Pseudomonas syringae. Research has not yet revealed how the disease spreads and enters a tree, but once it does, its effects can be catastrophic for the trees, as we now see. The second culprit is the leaf miner moth, which, although not fatal to trees, it can seriously weaken them by attacking the leaves.
Apart from the obvious scarring of the countryside that the death of so many of our finest trees would cause, will future generations of children be deprived of the pleasure of playing conkers?
