What To Do If Your Kumquat Tree Does Not Flower

These small trees have bright attractive medium-green leaves and aromatic white flowers. They are popular for their edible fruits and ornamental value.

Most gardeners struggle with how to get blooms on their kumquat tree.  If your kumquat tree does not flower, then it will not produce any fruit, which is very sad.  These are the gardeners who keep asking, “when do kumquats trees bear fruit?”

Kumquats have a long winter dormancy period and they don’t start growing until the weather warms up. Kumquat flowering season is in the mid-summer, so watch out for your trees during this season.

There are many problems that can lead to kumquat not flowering.  They include:

  • If the tree was recently transplanted it will not bloom.  It will be working hard to adapt its roots to its new location rather than produce blooms.
  • If your tree does not get enough sunlight, it will not bloom.  Kumquats enjoy a good amount of sunlight.
  • You might have pruned it too severely or too late in the spring – the kumquat will put all its energy into leaf re-growth not blooming.
  • Maybe the winter was too cold and severe for the tree.
  • The soil might be too boggy or lean or lacking enough zinc.

Good luck with it!

When Do Kumquat Trees Bear Fruit?

The flowering season of kumquat starts from early spring and can last all spring into summer if the humidity and heat are right.

Mid-summer the fruits begin to form and grow all the way to November when harvesting begins and goes all the way to January.   Harvesting can also start in December and end in April.

You will know the fruit is ready for harvest when it will be soft to the touch and has a deep orange color. Use shears or scissors to harvest the fruit.  Once harvested kumquats do not have a long shelf life – they will most likely last a week and no longer.  But you can store them in the fridge to prolong their shelf life.

How long does it take for a kumquat tree to bear fruit?

Kumquats are small, round fruits with an edible orange-colored skin and white flesh. They grow on the trees that are native to southeast Asia. A kumquat tree can grow up to six feet in height, although most varieties have a height of about three to four feet. Kumquat trees are easy to grow from seed. The tree can be pruned to shape and trained to a garden trellis or fence. Kumquats are available year round, but you’ll want to plant them in spring to enjoy the best harvest. Planting Instructions Kumquats need a lot of sunshine, so be sure to plant them in full sun. Plant them 12 inches deep and 30 inches apart. They will grow into a bushy shrub. Fruit trees have a wide variety of pests and diseases that can affect the fruit production. Soil type, planting conditions, climate, and other factors can influence the pest and disease risk for your kumquat.
They take usually about 18 months to bear fruit.

When should I feed my kumquat tree?

The best time to feed your kumquat tree is right before flowering. Cut off the blossoms, but leave about an inch of stem on each branch. This will encourage a new set of blossoms. Kumquats are very picky about their soil and sun. They like it warm, but not hot. The ideal soil temperature is 75°F to 85°F. If you live in a cooler climate, it may take more sunlight.

How do you prune a kumquat?

I like to cut the kumquat back hard, then wait until it stops producing new growth. This usually takes a couple of weeks, but if you don't prune your kumquat you'll probably lose most of the fruit before then. You can then cut off all the side branches and the top of the tree.

The best time to pick kumquats is in late summer or early fall. You can store them for up to two months in the refrigerator. They keep really well, so you can make some delicious fresh-tasting jelly with them.

What is the best fertilizer for kumquat?

I've been growing them for a few years now, and the best fertilizer I've found is a mix of:

1. 2 parts Miracle Grow (available in any garden store)

2. 1 part Fish Emulsion (available at any pet store)

3. 1 part Liquid kelp (available at any pet store)

4. 5 parts Epsom salts Mix these together and apply to your plants every month or so.

Can you transplant a kumquat tree?

If the tree is still growing and healthy, yes. You can cut it back to about 8 inches and then plant the new one. The new tree should be at least 4 inches taller than the old one. You could also transplant them as soon as they are big enough, but that will be more work.

Do kumquat trees grow fast?

A kumquat can grow up to 8 feet per year. That sounds pretty fast! And it is. But that doesn’t necessarily mean it’s the fastest growing fruit tree.


Growing a kumquat for a beginner is a bit tough but with the right information, it becomes easy and doable.   Finding the right tree is also crucial so look for one that is healthy and not root-bound.
