Through the year

Emergence

Emergence of new leaves and shoots typically occurs after the last spring frost and when air temperatures consistently rise above 50C.

Flowering

Flowering begins shortly after emergence, usually within two weeks, and can last for about three weeks.

Fruiting

Fruit development follows flowering, with berries ripening over a period of about a month.

Harvest

Harvest typically occurs from late spring to early summer, depending on the cultivar and climate, lasting for about a month.

Senescence

Leaves begin to senesce and drop with the first autumn frosts and shortening day lengths.

Dormancy

The plant enters dormancy after leaf drop, triggered by cold temperatures and short days, lasting through winter.

Timing is relative to your local season (temperate Northern Hemisphere).
