A Kumquat is a small evergreen citrus  and a native of China. It can grow in climates too cool for other citrus. They need full sun and tolerate any soil pH and most soil types as long as the soil is well-drained. They are also tolerate seaside conditions. Kumquat trees are suitable in colder area and withstand winter temperatures as low as -7 C.

They can grow from about 8 to 12ft / 2.25 to 3m( and have a vase-like or rounded shape. The trees are self-fertile, so you’ll only need one to produce fruit. Lovely fragrant white flowers appear in Spring followed by fruit in mid to late summer. The fruit is sweet and tart at the same time and is eaten without removing the peel.

Care for Kumquat Trees in Containers:

Kumquat trees don’t tolerate being root bound, so you will need a very large pot. Large drainage holes in the bottom of the pot are very important so you might need some fleece in the bottom of the pot to keep the soil from falling through. Raise the pot off the ground to improve the drainage and air circulation.

Kumquat trees in containers need extra protection during freezing weather because of the exposed roots. Either keep in a greenhouse or  cover them with a fleece blanket when frost threatens.

Kumquat Tree Care

As part of your kumquat tree care, you should keep the soil moist around young trees, but not wet or soggy. Once the tree is established, water during dry spells. Withhold fertilizer for the first two or three months. Use a fertilizer designed for citrus trees thereafter, following the label instructions. Use a layer of mulch over the root zone to help the soil hold moisture and inhibit weeds that compete with the tree for moisture and nutrients. Pull the mulch back several inches from the trunk of the tree. Kumquat trees don’t require pruning except to remove suckers that drain the tree’s resources. If you want to prune to shape the tree, do so after you harvest the fruit but before the flowers bloom in spring.

Kumquat Tree Problems

Kumquat trees are susceptible to root rot diseases. Avoid excess moisture and make sure the soil is well-drained before planting. Avoid piling mulch around the base of the tree.
