Mango trees grow best in tropical or subtropical climates where there is no danger of frost and especially in areas where the rainfall over the four summer months (June to September) totals 75 to 250 cm (30 to 100 in) and is followed by 8 months of dry weather. The trees grow optimally at temperatures of 24–27°C (75.2–80.6°F) with a relatively cool dry season and where heat is highest during flowering and fruiting. Mangos will tolerate almost any soil as long as it is well draining. Optimal growth will be achieved in rich, deep, well drained, loams. However, very rich soils will promote vegetative growth at the expense of flower and fruit production and should be avoided. The trees also grow well in sand, gravel and limestone soils. The optimum soil pH is between 5.5 and 7.5. Trees should be positioned in full sunlight for optimal fruit production
