First flowering

Record oak (pedunculate) first flowering when the male catkins release their powdery pollen.

If you have recorded oak (pedunculate) events before, please continue to record on the same tree.

Expected date range: mid April to late May

Available historic data: we have good records from 1933-1947 and from 1999 

Just right

  • Flowering on a pedunculate oak
