How to Grow Montmorency Cherry

Young tree with vigorous upright growth, developing main scaffold branches. Minimal flowering occurs.

Water consistently; prune to establish open vase or central leader form; remove competing branches; avoid heavy fertilization to prevent excessive vegetative growth.

Increasing branch structure with some flowering buds forming. Tree gains height and width rapidly.

Continue structural pruning; thin competing shoots; monitor for pests and diseases; apply dormant oil spray in late winter.

White to pale pink flowers emerge on 2-year-old wood in spring (late April to early May in northern climates). Blossoms appear before or with leaf emergence.

Avoid pruning during this stage; monitor for late frosts that can damage flowers; ensure adequate bee activity for pollination (though Montmorency is self-fertile, cross-pollination improves set).

Green fruit develops rapidly in June and ripens to bright red by early to mid-July. Fruit reaches 1-1.2 cm diameter with firm flesh and balanced sweet-tart flavor.

Thin fruit if extremely heavy set to improve size (space fruit 2-3 inches apart on branches); maintain consistent watering; watch for cracking in heavy rains; thin canopy if shading prevents color development.

Fruit ready to pick in mid-summer; leaves remain until fall. Tree enters dormancy after leaf drop in late October-November.

Harvest when fully red and slightly soft; prune after harvest to maintain shape and improve next year's production; apply dormant spray to prevent disease overwinter.
