Characteristics of the Nagami Kumquat

Nagami kumquats are in the citrus family along with oranges, tangerines, limes, lemons, and other similar fruits. Citrus fruits are known for being juicy, acidic, and flavorful and kumquats are no exception.

What Does it Look Like?

At first glance, kumquats look like small, oval-shaped oranges. The skin of a Nagami kumquat is the same color as a fresh, ripe orange and its texture is similar in appearance, though it’s a lot less tough than an orange peel. You can actually eat a kumquat peel!

Nagami kumquats are often oval-shaped and can sometimes be pear-shaped. When ripe they’re a little over an inch long and about 3/4 inches wide. They’re about the same size and shape as a large olive. Perfectly ripe fruit is firm with just a small amount of give when you gently squeeze it.

What Do They Taste Like?

Kumquats are both sweet and tart with a strong citrus flavor. The skin is sweet while the flesh and juice are tart and acidic. When eaten together you get an incredible blend of tangy, sweet-and-sour flavor.

If you prefer a sweeter flavor, you can squeeze some of the juice out before eating Nagami kumquats.

Kumquat Trees

Kumquat trees are beautiful in all seasons. They grow to between eight and fifteen feet tall and have dark green leaves with lighter green undersides. The branches hang low to the ground making the tree look somewhat like a shrub.

Growing Conditions

Kumquat trees like moist soil, especially for the first couple of years while the tree is getting established. Make sure to water regularly and don’t let the soil dry out. They aren’t too particular about soil acidity and grow well in most soil conditions, as long as it is well draining.

Nagami kumquat plants do best in full sun. Kumquat trees can tolerate cold temperatures but to produce fruit they need to be in warmer climates. When planted in-ground, kumquats grow best in zones 9 and above.

Don’t worry if you live in a lower zone, Nagami kumquats also grow well in containers and make a beautiful addition to your patio garden. If you live in a colder area just move your plant indoors for winter when temperatures start cooling down. You can also grow kumquat trees indoors year-round.


Nagami kumquat trees are self-pollinating. You don’t need any other trees or plants to get a good harvest of fruit. Pollinators like bees are all you need.

If growing indoors, you’ll need to hand-pollinate since insects won’t have access to your tree to perform the usual pollination.


Kumquat trees grown outdoors don’t require much pruning. You can prune to shape the tree if you like, this won’t harm the tree and can give it a more pleasing appearance.

If growing indoors, you may want to prune the tree more often to keep it a manageable size. A towering tree may be a beautiful sight in your yard but it won’t work in your living room!

The best time to prune is after harvesting fruit in winter before flowers start setting in spring.


Kumquats are usually ready to harvest in late winter but this can vary depending on where you live and whether you keep your tree indoors or outdoors. The fruits hold well on the tree so you can pick them as you want to use them, they don’t all have to be picked right away.

Pests and Disease

Anthracnose and Alternaria Leaf Spot are common citrus diseases you might see. Keeping an eye on your tree and identifying problems early can help ensure you’re able to treat problems before they become a major issue.

Aphids, mealy bugs, and scale bugs are common pests to watch out for.
