Full autumn tinting

Record full autumn tinting when all of the leaves on a tree have changed colour.

It may not be possible to record full autumn tinting every year, because sometimes the leaves fall before they have fully changed colour.

If you have recorded horse chestnut events before, please continue to record on the same tree.

If your tree is infected by leaf miner (the larvae of a tiny moth that forms burrows within the leaf tissue, resulting in leaf browning) the leaves might brown or tint early so please record this as first tint. The widespread infestation will be taken into account when the results are analysed.

Expected date range: early September to early November

Available historic data: we have records from 1999
