Kumquat Tree

Kumquat tree care should see this attractive garden tree produce fruit for you. The kumquat tree has the botanical name Citrus Japonica. However it came from China and is associated with the tropics and eastern Asia. Hence they are relatively small and quite attractive for the suburban garden. Indeed there are a number of varieties of kumquats. However, the most popular are:

  • Nagami
  • Marumi
  • Meiwa

Kumquat Tree Care

Location and Soil

Kumquat trees will grow in most soil types, regardless of the ph. However, they should be planted in a well draining location. While they thrive in the tropics they can survive in areas with temperatures down to – 8 Celsius (18F).

This tree thrives in full sunlight and enjoys high humidity of 50 to 70 per cent.


Should I grow kumquat from seed?

Kumquats do not grow well from seeds and are overwhelmingly grown by grafting. Consequently this is done by using the rootstock of another citrus fruit.

How to grow kumquat trees from cuttings.

  1. Select Cutting

    Make sure the cutting has 3 nodes (nodes are the knobby areas on the stem from where the leaves grow).

  2. Apply hormone

    Put the end of the cutting into the rooting hormone mixed with water.

  3. Pot

    Push a small hole in your potting mix. Next, put the cutting in the hole and firm up the soil so it can stand on its own. Also make sure the soil is damp to the touch, but not water-logged.

  4. Transplant

    When your seedling fills the pot, transplant it into your final growing spot in your tropical garden.

In spring, you should fertilise kumquat trees with a slow-release citrus fertilizer.

During the growing season, regular applications of a liquid fertilizer can increase a trees growth and productivity.

Make sure you water your tree well before and after you apply the fertiliser. Otherwise you may burn the plant.

Kumquat tree care can include pruning. However, any pruning should be done in the dry season (winter/spring).

Also cut diseased branches back completely, by pruning into healthy wood on the branch above any diseased portion.

Growing kumquats in pots

Kumquats are one of the easiest fruit trees to grow in a pot. However, if you do place your plant inside, make sure it is located where it will get as much light as possible. 


You should water trees regularly throughout the dry season. However, during the ‘wet’ they will be fine without any additional water. You should keep the ground at the base of the tree moist, but not wet or soggy. Mulching is recommended.

Kumquat Pests

Root rot can be a problem with kumquat trees. So while mulching is recommended, you should pull back the mulch a few centimetres from the base of the tree.

The pests of kumquat trees include mealybug, aphids and fruit fly. However, regular application of ‘white oil’ can help address some of these pests. Indeed, white oil is an effective organic pesticide that you can make at home.

Neem oil is also an organic solution to pests which is effective against certain insect and fungal disease. It is a useful tool in your kumquat tree care.
