Establishment
Year 1-2Young tree with minimal branching; focus is on root development and framework growth
Water consistently, stake if needed, prune to establish open vase structure with 3-4 main scaffold branches. Keep weeds clear.
Vegetative Growth
Year 2-3Tree develops canopy, branches fill in, leaves are bright green and vigorous
Continue pruning to maintain open center, thin crowded branches, remove any upright water sprouts. Mulch to retain moisture and regulate soil temperature.
Flowering
2-4 weeks in springPink-white blossoms appear in early spring (varies by region); tree is full of flowers before leaves emerge
Do not fertilize during flowering. Monitor for late frosts that can kill flower buds and reduce yield. Frost protection may be needed in marginally hardy zones.
Fruit Development & Growth
8-10 weeksSmall green fruit develop after flowers drop; fruit enlarges throughout summer; skin develops blush coloring
Thin fruit to 1 fruit every 6 inches (4-6 inches apart) in early June to increase size and quality. Remove damaged or diseased fruit. Maintain consistent watering.
Ripening & Harvest
2-4 weeksFruit becomes soft, fragrant, and develops characteristic coloring; white flesh shows rosy hues near skin
Stop heavy pruning. Harvest when fruit yields slightly to pressure near the blossom end. Do not harvest too early—tree-ripened fruit has superior flavor.

Harvest Tips
Harvest from mid-August to early September, depending on your zone. Peaches do not ripen further after picking, so wait until fruit is fully mature—it should yield slightly to gentle pressure and have a sweet aroma. Pick in the morning when fruit is coolest. Harvest every 2-3 days during peak season. Handle gently to avoid bruising.
