A tropical plant. It is native to C and S America. Guavas thrive in both humid and dry tropical climates. They do best in sunny positions. They grow wild and are also cultivated. In Papua New Guinea it grows well from sea level up to 1600 m and occurs up to 1900 m. In Nepal it grows up to 1400 m altitude. It is killed by frost. They fruit better where there is a cooler season. Temperatures near 30°C give best production. They are very widely distributed in open places and secondary forests throughout the islands of the Philippines and Papua New Guinea and can become weedy under some conditions. They produce better in soils with good organic matter. They prefer a well drained soil but can stand some water-logging. A pH of 5 to 7 is suitable. It can tolerate a pH from 4.6-8.9. Trees cannot tolerate salty conditions. It does not do well on atolls. It can grow in arid places. An annual rainfall between 1,000-2,000 mm is best. It grows in Miombo woodland in Africa.
