Citrus trees come from the Rutaceae plant family, and so are indigenous to Asia and India. These flowering trees are generally added to the garden landscape due to their white, ornamental flowers, in addition to their sweet and sour fruits. Citrus trees thrive in tropical, Mediterranean and subtropical climates. The longevity and life span of the citrus tree depends on the tree’s health and vigor. With proper cultural care, your citrus tree is less prone to succumb to disease, and have a longer lifespan.

Average Lifespan

The normal lifespan of a citrus tree is about 50 years. This age applies to both standard size and dwarf citrus. Trees start producing fruits sometime during their second through sixth growing season, and continue to produce fruit throughout their lifespan. Wholesome foliage is a sign of fruit production. A tree with a lot of healthy foliage produces more fruit. If it is particularly healthy, it is possible for citrus trees to reside as long as 100 years.

Planting in the Ground vs. Container Growing

Citrus trees planted in the ground often last and produce fruit more than those grown in containers or pots. Potted citrus trees need additional maintenance and care to keep the trees healthy. Depending on a tree’s growth rate, you must increase the magnitude of the expanding container every 12 to 16 weeks. Failing to do so leads to a stunted tree and root system, and general poor health and vigor. Extend the life span of the container-growing citrus tree by providing a new, bigger pot and new soil annually.

Life-Shortening Disease

A life-threatening and life-shortening disease called citrus greening, or Huanglongbing disease is a frequent bacterium that affects citrus plants and trees. Affected trees show symptoms of blotchy leaves and irregular dispersal of fruit growing on the tree. The fruit that’s created is misshapen and has a bitter flavor. The signs of this disease are slow to present themselves, leaving you unaware that your tree is contaminated. Citrus trees infected with this disease typically die or require removal over three to five years of infection. Those that survive are left with a shortened lifespan; usually down from 50 years to 15.

Proper Cultural Care

The very best method to increase the life span of the citrus tree is to practice proper cultural care and maintain the maintenance of your tree. Plant your citrus tree within an well-draining, full sun area in which the tree is sheltered from wind. Create a schedule of regular water and fertilization until the tree becomes established. Establishment times vary based on the type of citrus you’re growing. When the tree is established, it requires little maintenance other than pruning to remove dead, broken and diseased limbs. Since citrus trees are self-shaping, they simply require shaping to allow more sunlight to achieve lower sections of the tree.
