About Golden Apple

Spondias cytherea · also called Golden Apple, Ambarella · tropical

Golden Apple is a tropical fruit tree producing oval, golden-yellow fruits with crisp, juicy flesh eaten fresh or used in preserves, chutneys, and drinks across the Pacific, Caribbean, and Indian Ocean islands. This fast-growing, deciduous tree thrives in full tropical sun with fertile, well-draining soils and moderate, consistent moisture.

Cold limit: USDA 10–12 · RHS H1a (20–35°C)

What golden apple's hardiness rating actually means

Golden Apple is not cold hardy. It is a tropical houseplant that dies if it is left out through frost — there is no zone where it overwinters outdoors in a UK or cold-US climate. Its RHS rating of H1a means: Tropical — needs a heated room or greenhouse; no frost tolerance whatsoever. On the US scale that maps to USDA 10–12 — the zones where it can be left outdoors year-round.

New to these scales? The USDA hardiness zone map explained covers how the zone numbers work, and you can find your own zone with the zone finder.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly above about 15 °C (warm, never cold). Golden Apple has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for golden apple as it gets too cold:

Below about above about 15 °C, growth stalls and the leaves start to show cold stress — dark, water-soaked, or yellowing patches.
A single light frost blackens the foliage; a hard freeze kills the whole plant, roots included, and it does not recover.
Even a cold, draughty windowsill or an unheated porch in winter can be enough to damage it permanently.

Can golden apple go outside or overwinter — and where?

It can holiday outdoors in summer once nights are reliably above above 15 °C, in shade or dappled light, hardened off gradually.
Bring it back indoors well before the first autumn frost — do not wait for a frost warning, move it when nights drop toward 10-12 °C.
It will never overwinter outside in a temperate climate; the indoors is its winter home, full stop.

Work back from your local frost dates with the frost-date calculator: the last spring frost and first autumn frost are what really decide when golden apple can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1a figure above.
