5 Little-Known Factors That Could Affect Your Kumquat Trees

Factors That Could Affect Your Kumquat Trees

There are some things people don't know about kumquat trees that can affect them heavily. It's important to keep these factors in mind to avoid growth trouble.

Kumquat trees are easy to grow and are attractive, pleasant plants to have in your home or on your property. Many people find kumquats to be overly sour, but if you know how to prepare and use them properly, they can be quite tasty, too. 

This member of the genus Fortunella has origins in China where it has been grown for thousands of years. It is native to South Asia and the Asia-Pacific region and makes appearances in Indian, Japanese, Taiwanese, Philipino cuisine and is also popular in dishes of Southeast Asia. They made their way to Europe in 1864 thanks to Robert Fortune, a collector for the London Horticultural Society, and soon they could be found in the United States as well.

Although kumquats are only the size of grapes, they are packed with nutrients and are a rich source of Vitamin C, like their cousins in the citrus genus. Kumquats are high in antioxidants, support healthy immune function, and may even help to fight obesity because they are filling, but low in calories, making them an excellent snack.

It's no wonder so many people enjoy growing kumquat trees. They have many of the same needs as citrus trees, but there are certain things about them that home farmers should consider for best results. 


Kumquat trees need more zinc than other similar plants do. A zinc deficiency can be spotted easily as the plant will have mottled, yellow leaves that are quite small. You might think the plant is diseased when seeing these symptoms, but the problem can be solved easily with some zinc-rich fertilizer.


Because kumquat trees are rather tropical, some owners have a tendency to water them too much. These plants do want to stay moist, but be careful not to over water them. Once they are established, they will get most of their water from the earth through their roots and they should only be watered during dry spells.


Kumquat trees do not like being root-bound, so if you plan to grow yours in a pot, you will need a rather large pot. You'll also have to make sure the pot has plenty of drainage and air circulation because these plants are highly susceptible to root rot and other root problems. Learn more in our post about growing kumquats in containers.

When planting in the ground, consider spreading light mulch on the ground around the tree to help combat competition from grass and weeds. Your kumquat tree will thank you for it.


All plants need sun, but fruit trees like kumquat trees need as much as possible. Plant or place yours in a sunny spot in your yard and your tree will be happy and thrive. Trees in sunny locations produce more fruits than those in the shade and more fruits will make you happy, too.


These hardy trees are tolerant to colder weather, but they simply cannot bear frost or snow; intense weather can kill even established kumquat trees. If possible, bring your kumquat tree indoors in inclement weather.

If your tree is planted in the ground rather than in a pot and you predict a freeze is coming, cover it with a light blanket to protect it until the weather passes.

Kumquat Basics

Kumquats are a type of citrus fruit. Though they're not as common, they're right there alongside lemons, grapefruit, and oranges.

Like many other fruits, they're versatile and can be used in many ways. Add them to a dish, make kumquat jam, or eat them fresh. However you choose to eat them, you'll love the mix of sour and sweet flavors.

When eating kumquats, you can consume the outer rind, which is the sweetest part of the fruit. You'll likely get a high yield, so plan accordingly to avoid waste.

Temperature Requirements

Citrus trees are known for liking warm weather and not holding up so well in cold areas. Kumquat trees can actually stand up to pretty cold weather, though. You won't have to worry about them unless it gets as low as 10 degrees Fahrenheit.

Even if it does get that cold where you live, you can still grow kumquats. Simply grow your Kumquat trees in a container indoors if there's a chance of the weather getting that cold.

If you plan to grow your tree(s) outside, it's best to live in warm states, such as Texas, Louisiana, Florida, and Arizona.

Growing Options

Kumquat trees can be grown outdoors or indoors. Indoors, they can be grown in pots. They're beautiful plants, so you'll likely enjoy having them around.

If you choose to grow your kumquats outside, the trees are likely to get quite a bit bigger. They can reach heights of 15 feet.

Basics of Growing Kumquats

First, make sure you get your tree in the spring. If you need to re-pot the tree, make sure you use potting soil that's meant for use with citrus and cacti.

Kumquats need a lot of water. When watering, make sure you give it a lot. Drainage holes should have water coming through them.

This type of tree needs a lot of sunlight, so make sure it's placed in an area where it will get it. This could be indoors or by a window.

Water regularly, but not too often. When the top couple inches of soil is dry again, that means it's time to water.

Humidity is important when growing kumquats. Make sure you mist them or provide a humidifier if the air in your home is on the dry side.

Don't forget to fertilize! You'll do this in the spring and summer months, every two weeks.

What to Avoid

If you want to keep your kumquat tree in good health make sure you provide the right amount of fertilizer, not too much water, and keep it safe from the wind.
