Best Kumquat Trees for Your Location

Kumquat Trees in ContainersSome kumquat trees are much better performers in gardens than others. Choosing the best kumquat tree to grow depends upon your usage, location, climate and growing conditions.

There are three varieties of kumquats (also known as ‘cumquats’), the Nagami and the Marumi (also known as the Calamondin) and Meiwa.

Nagami: the ‘Nagami’ kumquat is the best one for eating straight off the bush, as it is the sweetest. It is the most commonly grown kumquat and produces a high volume of small, bright orange oval fruit.  It makes an excellent container or pot plant. A kumquat tree planted in a container or pot will grow to a height of around four feet, but outdoor trees can grow to 13 feet or more.

Marumi (Calamondin): Marumi trees fruit several times a year, with the main crop in winter. The bushes are dense and they are the best looking of all citrus in containers. A beautiful variety with variegated leaves also is available.

Meiwa: Meiwa kumquat trees are more cold resistant than other varietals with larger, sweeter fruit—about the size of a small tomato. They are grown in China and Japan, but are rarely seen elsewhere.

For more information on these kumquat tree varieties refer to our Varieties of Kumquat Trees blog.

Location

Australia

Both the Nagami and Marumi kumquat trees are popular and grown widely in Australia.

United States

Florida

Both the Nagami and Marumi kumquat trees are cold-hardy and grown in Florida where they are harvested November to April.

Southern California

Both Meiwa and Nagami kumquats are cold-hardy. Tree foliage can withstand temperatures below 20º F

and therefore can be grown in areas that are too cold for most citrus. Fruit, however, are more cold sensitive.

Nagami is the most common variety found in grocery stores. Nordman Seedless Nagami, a new

release, has really nice fruit 1 to 1½ inches long without seeds, therefore, especially easy to eat or

preserve.

Texas

Both Nagami and Meiwa kumquats have very good cold hardiness and are suitable for growing in Texas.

Varieties of Kumquat Trees to Grow

Nagami Kumquat (Cumquat) TreeDid you know that kumquat trees are probably the most overlooked of all citrus varieties. Kumquat (also known as ‘cumquat’) trees produce small fruits with intense flavour that should be used widely in cooking, but they are not. Forget limes, kumquats are a better choice. You can use the peel, zest or the entire fruit in making everything from cheesecakes to liqueurs.

Kumquat trees make very good container plants for small gardens or courtyards, with their handsome, compact foliage and lovely fragrant flowers. They belong to the genus Fortunella, although they were once classified with their close relatives, the Citrus. There are three varieties, the Nagami, the Marumi (also known as the Calamondin) adn the Meiwa.

Nagami Kumquat Tree
The ‘Nagami’ kumquat  is the best one for eating straight off the bush, as it is the sweetest. It is the most commonly grown kumquat and produces a high volume of small, bright orange oval fruit. The whole fruit, including the skin, can be eaten fresh, or made into marmalade or used for kumquat liquor and can be preserved as candy. It makes an excellent container or pot plant. A containerized tree will grow to a height of around four feet, but outdoor trees can grow to 13 feet or more.

Marumi Kumquat Tree
The ‘Marumi’ (also known as ‘Calamondin’) kumquat produces fruit that are flattened, like mini mandarins. Marumi trees fruit several times a year, with the main crop in winter. The bushes are dense and they are the best looking of all citrus in containers. A beautiful variety with variegated leaves also is available. Marumi trees are not quite as pretty in the ground, where they reach 3-4 m. This is the variety used for Chinese New Year celebrations.

Meiwa Kumquat Tree

Meiwa’ kumquat trees are more cold resistant than other varietals with larger, sweeter fruit—about the size of a small tomato. They are grown in China and Japan, but are rarely seen elsewhere.

Kumquat Tree Care
• Full sun
• Before planting, dig in plenty of chicken, cow or horse manure into the ground.
• Keep citrus trees well watered when young fruit is forming in spring and early summer.
• Grass and citrus don’t mix. Keep the area beneath your citrus free of grass and weeds.
• Cover with a mulch such as lucerne, composted leaf litter or compost, but keep the mulch away from the tree trunk to avoid collar rot.

Kumquat Trees in Containers or Pots
• Trimmed and rounded citrus trees in pots are one of the main components of the fashionable Mediterranean or Tuscan garden. They have the added advantage of being able to be moved from place to place to enjoy the sunshine.
• Ensure that citrus in pots are well watered – once or twice a week in warmer months.
• Fertilise every six to eight weeks in spring and early summer.
