January
- Late-dormant / early-spring pruningPrune · Jan 24 – Feb 21
Prune sweet cherries in late winter to early spring as growth begins, or in dry summer after harvest. Extension guidance favors these drier windows over midwinter to reduce bacterial canker infection of fresh cuts. Cherries fruit on long-lived spurs, so cuts are light once the frame is set.
February
- Bloom — pollinator & cross-pollination awarenessNote · Feb 28 – Feb 28
Sweet cherries bloom in spring and many varieties need a compatible pollinizer blooming at the same time; open flowers are frost-sensitive. Bees are active, so extension guidance is to avoid insecticide application during open bloom. Awareness/timing only.
March
- Petal-fall / pre-harvest monitoring windowSpray timing · Mar 7 – Mar 28
Petal fall through fruit coloring is the timing reference many extension calendars use to begin scouting for brown rot and spotted-wing drosophila as fruit ripens. This entry marks the window only.
Timing window per the cited source. For product and rate guidance, consult your local Cooperative Extension and always follow the label.
May
- Harvest windowHarvest · May 1 – Jul 31
Pick when cherries reach full color and sweetness for the variety; they do not ripen further off the tree. Sweet cherries ripen late spring into midsummer. Rain near harvest can crack fruit, so harvest promptly when ripe.
November
- Dormant-season treatment windowSpray timing · Nov 1 – Jan 17
The dormant window before bud swell is the timing reference extension calendars use for overwintering pests and for brown-rot and bacterial-canker management on cherries. This entry marks the window only.
Timing window per the cited source. For product and rate guidance, consult your local Cooperative Extension and always follow the label.
