Budburst

As the winter buds swell, they bud scales may turn greenish pink. Record horse chestnut budburst when the colour of the new green leaves is just visible between the scales of the swollen bud. Leaves and flowers come from one bud.

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

Expected date range: early March to mid April

Available historic data: we have some records from 1977-1999
