Growing a Kumquat Tree

Kumquat trees can be planted from seeds, but it is better to buy a grafted potted plant from a reputed nursery. Like other citruses, it also grows best in an area that remains warm and receives full sun. However, it is also possible to grow it in partial shade, plant it under a large tree, which will help the plant in getting additional frost protection during the winter.

Kumquat trees are dwarf and seldom goes high above 3 meters (10 to 12 feet), so you don’t need to assign a big space to grow them in your garden. This makes growing kumquat in containers possible too.

Watering and Fertilizing

At the beginning of planting a kumquat tree, you will need to water more and keep the soil moist so that the plant will establish itself well on the ground.

Once the plant is established, reduce watering, when you find the topsoil dry. While the tree is in bloom, or if the fruits are developing you’ll need to care about watering, making sure the soil is evenly moist around the tree.

Withhold fertilization for the first month after planting. After the first month, fertilize the plant three times a year, in spring, early summer and late summer.

Prune after the harvest in fall but before the arrival of new flowers. Remove any dead or broken branches. If you notice suckers at the base of your tree, prune these too.
