Planting calendar for Tempe
Frost is rare here, so sowing goes by warmth: tender crops like tomatoes go outdoors Mar 3 to Mar 28, and Aug 26 to Nov 24.
- Frost
- Frost is rare here
Frost comes in fewer than half of years, so there’s no last or first frost date to work from. Dates below go by how warm it is instead. On a clear, still winter night a light frost can still happen, so cover tender plants then.
