January
- Late-dormant / delayed pruningPrune · Jan 17 – Feb 7
Prune peaches late in the dormant season, as buds begin to swell before bloom. Extension guidance favors this delayed timing over midwinter pruning to reduce entry for wood-canker and other diseases. Open the center to an outward-growing vase and remove old fruiting wood.
February
- Bloom — frost & pollinator awarenessNote · Feb 28 – Feb 28
Peaches bloom early and open flowers are vulnerable to spring frost; be ready to protect the tree on frost nights. Bees are also active now, so extension guidance is to avoid insecticide application during open bloom. Awareness/timing only.
March
- Petal-fall / shuck-fall monitoring windowSpray timing · Mar 7 – Mar 21
Petal fall into shuck split (the shuck slipping off the young fruit) is the timing reference many extension pest- and 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 · Mar 28 – Apr 18
Thin young fruit to roughly 15–20 cm apart a few weeks after bloom, once natural drop has finished. Peaches set heavily and thinning is essential for size and to prevent limb breakage.
June
- Harvest windowHarvest · Jun 1 – Sep 30
Pick when ground color turns from green to yellow, fruit gives slightly to gentle pressure, and separates easily from the stem. Harvest timing shifts widely by variety and by your local season, spanning early summer to early fall.
November
- Dormant-season treatment windowSpray timing · Nov 1 – Jan 17
The dormant window—before buds swell—is the timing reference extension calendars use for peach leaf curl and overwintering pest management, which is why leaf-curl protection is directed at this pre-bud-swell period. 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.
