When to plant almonds
A peach relative that flowers even earlier than a peach, which is the whole difficulty. Beautiful in bloom, and in most temperate gardens that is all it will ever be.
First worthwhile crop
Year 4
After planting, not after sowing.

6a to 9a
Winter cold sets the limit here, not the calendar.

Those weeks become real dates once you name a place.
Timing, in frost-relative terms
Nothing about a standing crop is sown to a calendar. Once planted, almonds 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 4 after planting.
- Needs roughly 400 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 6a–9a.
Getting the timing right
Plant dormant. Almond blossom opens in late winter, so a crop depends entirely on a mild spell holding rather than a cold snap arriving. Commercial almonds are grown in Mediterranean climates for exactly this reason.
Frost tolerance
The tree tolerates -20C in dormancy. The flowers, which can open in February, are destroyed at -2C, so the frost date that decides an almond crop falls far earlier in the year than for any other nut.
