Through the year

Emergence

Bud break and leaf emergence typically occur after the last spring frost and when air temperatures consistently rise above 10°C.

Flowering

Flowering usually follows leaf emergence by about two weeks.

Fruiting

Fruit development begins after flowering, with ripening occurring over several weeks in early to mid-summer.

Harvest

Harvest season for black mulberries typically spans from early July through August, depending on climate and cultivar.

Senescence

Leaves begin to change color and drop in autumn, often triggered by shortening days and the first light frosts.

Dormancy

The tree enters full dormancy after leaf drop, lasting through winter until spring conditions return.

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