How to Start It
★ Recommended for beginners
Buy a grafted calamansi on a suitable rootstock — it's self-fertile, so one plant fruits. In any zone with frost, grow it in a large pot you can wheel to a bright, cool indoor spot for winter.
A small, sour Philippine citrus (calamondin) — extremely heavy-bearing, ornamental, and a favourite houseplant citrus. Self-fertile, used like a tart lime/lemon. Tender (to about -3°C), so container-grown and overwintered bright indoors; it often fruits and flowers indoors year-round.

Growing Tips
- 1Calamansi wants full sun, free-draining slightly acidic soil, and even moisture — let the top few cm dry between waterings, never waterlogged.
- 2Feed with a citrus food in the growing season.
- 3In frost zones it lives in a pot and overwinters bright and cool indoors (not beside a hot radiator).

When to Pick

How to Harvest
- 1Pick calamansi any time from green to orange once juicy — they're used for their sharp juice rather than eaten fresh.
- 2The tree carries fruit almost continuously, so harvest as needed.
