Citrus Tree

Citrus is a diverse genus of evergreen fruiting trees and shrubs that includes oranges, lemons, limes, mandarins, grapefruit, and related plants. Plant requirements and mature size vary substantially by species and cultivar, so use the individual selection’s traits when planning space and climate. ## Growing Conditions Most citrus performs best with full sun, well-drained soil, and protection from strong winds. Cold tolerance differs among varieties, and fruit quality can depend on warm growing conditions; choose a selection suited to the local climate.

The broad genus record includes these differences rather than describing one uniform fruit or flowering schedule. ## Maintenance Avoid persistently wet soil and allow adequate room for the selected plant’s mature canopy. Check care guidance for the named citrus species or cultivar, especially for winter protection and fruit ripening.
