When to plant passionfruit
Fast, vigorous and short-lived - five to seven productive years is typical. Fruits in its second year and needs a warm, frost-free spot to get there.
First worthwhile crop
Year 2
After planting, not after sowing.
Hardy in USDA zones
9a to 11a
Winter cold sets the limit here, not the calendar.
Frost tolerance
Tender
How much cold the plant itself will take.
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, passionfruit 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 2 after planting.
- Hardy in USDA zones 9a–11a.
Frost tolerance
Damaged below about -1C and killed at -2C. In a marginal climate it is grown as a container plant that overwinters under glass.
