Oranges through the year
Against the frost risk in Ho Chi Minh City
Why these dates
Plant in spring once the soil has warmed, so the tree has a full season to root before its first winter. Citrus in containers should go out after the last frost and come in before the first - the move is the whole calendar in a cool climate.
Foliage is damaged around -3C and the fruit itself freezes at about -2C. Wood damage begins near -4C on a mature tree and considerably earlier on a young one.
Oranges are planted once and then left in place, so there is no sowing offset to resolve. Nor is there a dormant season to plant into: this crop keeps its leaves and keeps growing through the winter, which is exactly why cold damages it. The window on this page therefore waits until the last frost in Ho Chi Minh City has passed and the soil has begun to warm, giving the roots the longest possible run before the cold returns.
Ho Chi Minh City sits in zone 13a, which is milder than this crop wants, and a winter that never really arrives is its own problem. The dates below still describe the right time of year; the open question is survival rather than timing.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 3, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
