Nagami kumquat

The Fortunella margarita, also called the oval kumquat or the Nagami kumquat, is a great ornamental tree to plant in your yard in the Tampa Bay area. The tree is a close relative to Citrus species and is incredibly frost hardy. The fruit from the tree is oval shaped, a bit different than the standard round kumquat. The Nagami is an evergreen tree with beautiful foliage and flowers. The tree goes into dormancy in early autumn which lends to its better frost hardiness than its sister kumquat trees with a more tart taste.

Care Information

The Nagami kumquat can be grown in any soil but those that are less alkaline support the tree the best. Whether you plant the tree outdoors or in a container on the patio, there is no need for chemicals or pesticides as the tree is highly resistant to disease and pests. Water well for the first few days after planting in well-draining soil and then back off a bit; weekly watering of an established plant is all that is needed.
