How to Prune Kumquat Trees in 4 Steps

Kumquats grow on beautiful evergreen trees that make amazing additions to backyard landscaping. The orange oval fruits pop against the dark green foliage of these stunning little trees.

Mature kumquat trees are relatively compact, growing to around 15 feet tall. There are also dwarf varieties that only grow six to eight feet in height.

Do you live in an area that always stays warmer than 20 degrees Fahrenheit? If you do, then you can grow kumquat fruits at home in your garden.

Kumquats produce fruit that can be harvested from November through April. You can improve kumquat fruit production through light pruning.

Pruning kumquat trees is a very straightforward process. You can follow these simple steps to improve your fruit trees’ health and productivity.

What you will need:

Always be cautious when using a ladder. Ensure you have a stable surface, and consider asking a friend for assistance.

You’ll want to protect yourself from falling branches while pruning kumquat trees. Gear up for safety by strapping on a helmet and safety goggles.

Step 1: Remove Water Suckers

Water suckers rob a tree of nutrients and energy.

Water suckers are the small green branches that emerge and shoot up from the trunk. They divert much of the energy produced by photosynthesis into new foliage growth.

You should prune these branches if you want a more substantial harvest. Use clean loppers to clip water suckers where they meet the tree.

You want mature trees to concentrate their energy on fruit production instead of green growth. This will lead to sweeter fruit and higher yields.

Step 2: Remove Damaged and/or Diseased Wood

Does your kumquat tree have branches that lack foliage or fruit growth? If so, you should remove them.

Unproductive branches can be caused by many different things. These limbs could have been severely damaged, or they might have been burdened by one or more pathogens.

Regardless of the reason, barren branches should be removed. Doing so promotes healthy growth in the rest of the tree.

Ensure you cut away all damaged or diseased wood, leaving only healthy green wood. Sanitize your loppers with alcohol afterward to prevent the spread of infection.

Step 3: Remove Cross Branches

Removing cross branches is an often-overlooked pruning task that is quite important for the health of your fruit trees. Doing so can significantly improve fruit production and minimize pests and pathogens.

Step back and examine your kumquat tree as a whole. Look for spindly branches that cross over the trunk.

These limbs usually just crowd the canopy without producing significant foliage or fruit. Prune some of these cross branches to improve air circulation and sunlight exposure.

Step 4: Trim to Desired Shape

Envision how you want the tree to look and consider sketching the general outline. Carefully clip scraggly areas to improve the overall appearance of your kumquat tree.

Kumquat Tree Pruning Tips

You should be mindful of a few things when pruning kumquat trees, particularly in regard to protecting them from damage.

You must always put the health of your tree first. Understand that each tree is a living creature that must heal from pruning wounds.

Never remove more than 25 percent of a tree in one season. This amount of pruning is difficult to recover from.

Carefully consider each cut before you make it. The best way to avoid over-pruning is by planning the process from start to finish.

Sketching the final outline and slowly working toward this goal can help guide your pruning.

You might want to seal any cuts you make to protect against fungal and bacterial infections. Bonide Pruning Sealer is a trusted option to help keep your trees safe from disease.


What is the lifespan of a kumquat tree?

Kumquat trees are relatively short-lived compared to other fruit trees. On average, these citrus trees live to be 50 years old.

You can extend the life of your kumquat trees by properly caring for them. From fertilizer to pruning, every step is vital for healthy trees.

Can you grow kumquats in pots?

Kumquat trees make fantastic container plants since they are very compact and hardy. Gardeners in colder climates often grow these citrus trees in pots to protect them from frost.

Why does my kumquat tree have thorns?

Do you have a young kumquat tree that appears to be sprouting thorns? If so, don’t be alarmed! When some citrus trees experience excessive stress, they may develop thorns as a defensive tactic.

As you’ll see in our blog post, thorn development is more commonly found in the Nagami Kumquat variety. Still, it can occur in most types of citrus trees.

You can remove these thorns during routine pruning without harming the tree. You might consider applying pruning sealer on the wounds to protect the tree from disease.
