Dormancy & Winter Chilling
October-FebruaryTree is leafless and dormant; requires 600-900 chilling hours below 45°F (7°C) to break bud dormancy properly
No active watering needed; prune during late dormancy in late winter. Remove dead or crossing branches. Thin crowded branches for air circulation.
Spring Bud Break & Flowering
March-AprilPink/white flower buds swell and open into clusters of blossoms along branches
Protect blossoms from late frosts if possible (frost cloth, irrigation). Do not fertilize yet; apply dormant oil if needed for pest control. Avoid overhead watering to reduce disease.
Fruit Set & Early Development
April-MayFlowers fade and small green fruit develops where blossoms were; fruit rapidly enlarges
Thin fruit to 1 peach every 6-8 inches on branches to promote larger fruit size and prevent branch breakage. Remove diseased or deformed fruit. Begin regular watering schedule.
Mid-Season Growth & Coloring
June-JulyFruit continues to enlarge and begins showing red blush coloring on yellow-orange background; tree is in full leaf
Maintain consistent moisture (1 inch/week). Apply balanced fertilizer in early summer if needed. Monitor for pests (Japanese beetles, oriental fruit moths). Support heavy-laden branches with stakes or props.
Ripening & Harvest
August-SeptemberFruit reaches full size (2.5-3+ inches diameter), develops full red blush, and becomes fragrant and slightly soft to gentle touch
Stop heavy nitrogen fertilization to avoid soft fruit. Water regularly but do not overwater. Monitor daily for ripe fruit. Reduce watering slightly as harvest approaches. Harvest when fruit yields slightly to pressure but is still firm.

Harvest Tips
O'Henry peaches ripen in late August to early September, typically 120-150 days after bloom. Harvest when fruit has a strong fragrance and yields slightly to gentle hand pressure but is still somewhat firm (not mushy). Gently twist and lift ripe fruit from the branch. Do not squeeze hard or bruise fruit. For best flavor, harvest fully ripe. Store at room temperature for 1-2 days if needed, or refrigerate for up to 2 weeks. Peaches continue to soften after picking but do not increase in sugar content.
