  1. April

    • Late-dormant / early-spring pruningPrune · Apr 21 – May 19

      Prune tart cherries in late winter to early spring as growth begins, or in dry weather after harvest, to reduce bacterial-canker and silver-leaf infection of fresh cuts. Tart cherries are naturally smaller and bushier and need only light thinning of the canopy once framed.

  2. May

    • Bloom — pollinator awarenessNote · May 26 – May 26

      Tart cherries are self-fruitful and bloom in spring; open flowers are frost-sensitive. Bees are active, so extension guidance is to avoid insecticide application during open bloom. Awareness/timing only.

  3. June

    • Harvest windowHarvest · Jun 1 – Jul 31

      Pick when fruit is fully colored, soft, and tart-sweet; tart cherries typically ripen in early to midsummer, a little after sweet cherries. They are usually processed, so harvest when fully colored for best flavor.

    • Petal-fall / pre-harvest monitoring windowSpray timing · Jun 2 – Jun 23

      Petal fall through fruit coloring is the timing reference many extension calendars use to begin scouting for cherry leaf spot, brown rot, and spotted-wing drosophila. 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.

  4. October

    • Dormant-season treatment windowSpray timing · Oct 16 – Apr 14

      The dormant window before bud swell is the timing reference extension calendars use for overwintering pests and for leaf-spot and brown-rot management on tart 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.

    • Fall cleanup and sanitationCare · Oct 16 – Nov 13

      Rake and remove fallen leaves and mummified fruit after leaf drop to reduce overwintering cherry leaf spot and brown-rot inoculum.
