When to plant peaches
Bears young and generously, then spends its life fighting peach leaf curl in any climate with a wet spring. Worth growing under cover or against a wall where the rain can be kept off the emerging leaves.

Timing, in frost-relative terms
Nothing about a standing crop is sown to a calendar. Once planted, peaches stay in the ground for years, so the question is not when to sow but whether your winter is survivable and your planting window is open. Both answers come from your frost dates.
- Expect a first worthwhile crop in year 3 after planting.
- Needs roughly 600 chill hours below 7.2°C (45°F)45°F (7.2°C) over winter to set fruit, which rules out the warmest climates.
- Hardy in USDA zones 5a–9a.
Getting the timing right
Plant dormant. Peach blooms very early - often the first thing in the orchard to flower - so in most temperate gardens the crop depends entirely on whether that bloom escapes a frost. Under glass or against a warm wall the flowers usually need hand-pollinating, because nothing much is flying that early.
Frost tolerance
The tree survives hard winters; the flowers do not survive a spring frost. Low-chill cultivars exist for subtropical climates, but the standard varieties need a proper cold period and will flower erratically without it.
Classified as hardy.
