When to plant mandarins
Mandarins include selections with different ripening times, flavour and cold response. Keep the exact cultivar and rootstock on the label; advice for one satsuma or tangerine is not a reliable schedule for every mandarin.

Timing, in frost-relative terms
Mandarins occupy their position for years. Check mature size, drainage, winter survival and cultivar requirements before choosing a planting window. Frost dates alone cannot tell you whether the plant will thrive, flower or fruit.
- Approximate first cropping: year 3 after planting; nursery plant age, variety and growing conditions change this.
- Hardy in USDA zones 9a–11a.
Getting the timing right
Use a sunny position and drained soil with steady access to moisture. A container allows winter shelter but also needs room for a developing root system. Repot carefully rather than repeatedly breaking roots to force the plant into a small space.
Frost tolerance
Check the named variety and local forecast before exposing young growth. The catalog cold-damage figure is a reference, not a guarantee: plant age, acclimatisation, wind and the duration of a freeze affect damage.
Classified as tender, with a catalog cold-damage reference of -6°C (21.2°F)21.2°F (-6°C). Exposure duration, growth stage and acclimatisation change cold tolerance.
Before you plant mandarins
Use the calendar to plan ahead, then check the conditions in your own garden.
- Check the local overnight forecast before planting out. Delay planting or keep protection ready if frost is forecast, even after the historical last-frost date.
- Check mature size, drainage and cultivar suitability before choosing a permanent position. A suitable planting window does not guarantee long-term survival or fruiting.
Choose a named mandarin for your local ripening season
Use a sunny position and drained soil with steady access to moisture. A container allows winter shelter but also needs room for a developing root system. Repot carefully rather than repeatedly breaking roots to force the plant into a small space.
Monitor flowering, fruit retention and ripening as separate stages. If fruit remains poor in flavour, review the cultivar and available warmth and light before adding more fertiliser. Inspect the canopy when moving a pot between outdoor and indoor conditions.
What to record this season
Did the chosen mandarin mature within your available outdoor season? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.
