Stage	Typical Window	What to Look For
Candle elongation BBCH 11	Feb 15-Mar 15	Pale, elongating shoots (candles) covered in papery scale leaves. Two needles per fascicle emerge as candle extends
Pollen release BBCH 61	May 1-May 31	Male strobili usually clustered at base of current year's candles; yellow pollen visible
Pollen shed complete BBCH 69	May 15-Jun 15	Female conelets (small, reddish or purple) visible at shoot tips after pollination
Cone development (year 1-2) BBCH 71	Jun 1-Aug 31	Cones elongate. Two-needle fascicles characteristic. Serotinous cones (remain closed until fire/heat). Mature over second year
Cone maturity and seed shed BBCH 85	Sep 1-Nov 30	Woody cones remain sealed at maturity. Fire-adapted; cones open when exposed to heat, releasing winged seeds
