Cherimoya are subtropical or mild-temperate trees that will tolerate light frosts. Young growing tips are affected at 1.5ºC and mature trees killed or severely injured at –4ºC. Young trees can withstand a temperature of –3.5°C. Cherimoya trees need between 50 and 100 hours of chilling or they will slowly go dormant and have delayed foliation.

Trees prefer a sunny exposure, buoyant marine air and cool nights. Plant on a north facing hill, or near a north facing wall to collect heat, which will encourage early bud-break and fruit ripening, but take care with position to ensure leaves and fruit won’t get sunburnt. Trees growing on cold, south facing slopes tend to drop their leaves and flower later than on warmer sites, so fruit maturity will be delayed. Trees need protection from strong winds and ocean winds, which can cause damage or interfere with pollination and fruit set.

Fruit exposed to very cool nights near maturity have a tendency to split or suffer skin blackening if not well protected by leaves.

Cherimoya grow best close to the equator at high cool altitudes such as in the valleys of the Andes. In Colombia and Ecuador, they grow naturally between 1,400–2,000m where temperatures range from 17°–20°C. Loja, in southern Ecuador, has good producing areas with average annual temperatures of 15–20°C and little difference between the warmest and coolest temperatures. In Peru, the ideal climate for cherimoya is between 18°–25°C in summer and 5°–18°C in winter. They generally don’t succeed in hot lowland tropics or high mountainous peaks.

In New Zealand cherimoya do best in the relatively frost–free Northland area (where temperatures range from 18º–30ºC in summer and 6º–18ºC in winter), and in the Bay of Plenty. Most other places are generally too cold and prone to frosting.

Although cherimoya aren’t used to the more extreme temperatures found in California, they seem to grow well in the coastal and foothill areas of the south, particularly at slight elevations, 5–20km from ocean.

In natural growing areas, cherimoya receive approximately 700–1,400mm of rain. This level can easily be attained in commercial orchards with irrigation. If rainfall is high during blooming, it can produce fungal problems. Some trees in Bolivia have epiphytes growing on them, which shows how wet the growing conditions there can be.
