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 trees. 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 kumquat 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. Many problems 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 rather than blooming.
  • Maybe the winter was too cold and severe for the tree.
  • The soil might be too boggy or lean or lacking enough zinc.

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.

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.
