Through the year
Emergence
Bud break and leaf emergence typically occur after the last spring frost and when air temperatures consistently rise above 100C.
Flowering
Flowering occurs approximately 30 days after leaf emergence, typically in late spring to early summer.
Fruiting
Fruit development begins after flowering, with chestnuts maturing over approximately 90 days.
Harvest
Chestnuts are typically ready for harvest from late September through October, often triggered by the first autumn frosts which cause burrs to open.
Senescence
Leaf senescence and fall are triggered by the first autumn frosts and shortening day lengths.
Dormancy
The tree enters dormancy after leaf fall, lasting through winter until chill requirements are met and spring temperatures rise.
Timing is relative to your local season (temperate Northern Hemisphere).
