Growing Kumquats  (cumquats)

Kumquats are dwarf evergreen citrus trees, similar to oranges that are widely grown in the Far East. It is possible to grow them outdoors in warmer areas but it is more likely to be grown in a container in a greenhouse or conservatory. Varieties suitable for growing in this fashion are Marumi and Nagami, which are grown as bush trees.

Soil Conditions and Siting

They require a medium to heavy loam with plenty of organic matter to retain moisture. The pH of the soil should be between 6.0 and 6.5. The site should be sheltered and sunny.


Plants are available as container grown or balled, both of which can be planted at any time of the year.



Mulch with well rotted manure or compost in spring.


Ensure that the plant is kept well watered. This is particularly important when the fruits are swelling.


Cut back the current seasons growth after harvesting.


Kumquats are ripe when they begin to turn orange. They can be eaten raw or made into marmalade.
