Citrus Flowering Habits

Citrus trees are evergreen and can have both flowers and fruit at the same time, so they are treated a bit differently than other fruit trees. They store food reserves in their leaves and must therefore be protected from stresses that will cause leaf drop. Although the cycles are not as obvious as the cycles in temperate fruit trees, citrus trees go through different stages throughout the year. When temperatures drop below 56&deg F, the trees stop growing and go into a semi-dormant state. After a period of such cool weather, they can withstand brief cold snaps much more easily than when they are actively growing. It only takes a few days of warmer temperatures to make them more vulnerable, though. In the spring they have a flush of growth and their major bloom period. Some varieties tend to bloom lightly throughout the year; water shortages or other stresses can trigger a second bloom.
