Apricot care calendar — zone 5

The year at a glance

1. May

   • Bloom — frost & pollinator awarenessNote · May 26 – May 26

     Apricots are among the earliest stone fruit to bloom and open flowers are highly frost-sensitive; be ready to protect on frost nights. Bees are active, so extension guidance is to avoid insecticide application during open bloom. Awareness/timing only.

2. June

   • Harvest windowHarvest · Jun 1 – Jul 31

     Pick when fruit is fully colored, aromatic, and gives slightly to gentle pressure. Apricots ripen in early to midsummer; timing shifts by variety and local season.

   • Petal-fall / shuck-fall monitoring windowSpray timing · Jun 2 – Jun 16

     Petal fall into shuck split is the timing reference many extension brown-rot monitoring calendars use to begin scouting. 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.

   • Thin fruitThin · Jun 23 – Jul 14

     Thin young fruit to roughly 5–8 cm apart a few weeks after bloom once natural drop finishes. Thinning improves fruit size and reduces limb stress in heavy-set years.

3. July

   • Summer pruning (disease-avoidance timing)Prune · Jul 1 – Aug 31

     Apricots are prone to Eutypa and other canker fungi that infect fresh cuts in wet weather, so extension guidance is to do the main structural pruning in summer during dry conditions rather than in the dormant season. Maintain an open center and renew fruiting wood.

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 brown-rot management on apricots. 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

     Remove mummified fruit and rake fallen leaves after leaf drop to reduce overwintering brown-rot inoculum.
