Guava will grow optimally between 23 and 28°C (73–82°F) but established trees can tolerate short periods at -3 to -2°C (27-28°F) although temperatures below 15°C (60°F) can cause the tree to cease producing fruit. The causal organism has been identified as F. oxysporum f. sp. F. oxysporum thrives at soil temperatures above 24 °C (75 °F) and can live indefinitely in soil without access to living host plants.
