Delicious but high-maintenance deciduous fruit tree requiring specific chill hours, annual pruning, and pest/disease management. Trees are relatively short-lived (15-25 years) compared to apples or pears. Freestone varieties (flesh separates from pit) for eating, clingstone for preserving. Low-chill varieties make peach growing possible in subtropical zones. Self-fertile - single tree produces fruit. Grafted on peach or plum rootstock.
