Growing Kumquat Trees

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.

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. This is done by using 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. Put the cutting in the hole and firm up the soil so it can stand on its own. 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 growing spot in your tropical garden.
