Citrus trees thrive in a subtropical to tropical climate, which is characterized by the following conditions:
-
Temperature: Citrus requires warm temperatures, ideally between 20°C to 30°C (68°F to 86°F) during the growing season. They are sensitive to frost, with temperatures below -2°C (28°F) potentially damaging the trees and fruit.
-
Sunlight: Citrus trees need full sunlight for at least 8 to 10 hours a day. Adequate sunlight is crucial for photosynthesis and fruit production.
-
Rainfall: Citrus generally requires moderate rainfall and well-draining soil. While they need water, too much can lead to root rot. An annual rainfall of about 1000mm to 1500mm (39 to 59 inches) is considered ideal.
-
Humidity: While citrus trees can tolerate a range of humidity levels, they generally prefer moderate humidity. High humidity can encourage fungal diseases.
-
Soil: Well-drained, sandy-loam or loamy soil is best for citrus cultivation. The soil should be rich in organic matter and have a pH level of around 6 to 7.
In summary, a warm climate with ample sunlight, moderate rainfall, and well-drained soil is optimal for growing healthy citrus trees.
