Plant Description
Citrus is a genus of evergreen trees and shrubs that produce fruits such as oranges, lemons, limes, and grapefruits. Most varieties are self-fruitful and do not require another variety for cross-pollination. Citrus varieties differ in the amount of heat required to mature their fruit. Lemons and limes need the least amount of heat and will produce good fruit near the coast. Valencia oranges have a higher heat requirement. They produce good fruit in coastal and inland areas but are not adapted to the desert. Navel oranges require more heat and produce their best fruit in inland valleys. Mandarin oranges, tangelos, blood oranges, and grapefruit need even more heat to produce top quality fruit.
Cultural Tips
Cultural practices such as site selection, soil preparation, planting, pruning, and watering are important for plant health, pest management and pest reduction when growing citrus.
