Holes in Bok Choy Leaves: Reasons and Solutions

by | Jul 3, 2022 | Care | 0 comments

Bok choy is a delicious and healthy vegetable that is often enjoyed in stir-fries and salads. However, many people are dismayed to find small holes in the leaves of their bok choy plants. In this blog post, we will discuss the possible causes of these holes and how to solve the problem!

Why Are There Holes in My Bok Choy Leaves?

There are holes in your bok choy leaves because a pest is using them as a food source. The most likely culprits are caterpillars, slugs, or snails. The most common pests that eat bok choy leaves are flea beetles, cabbage loopers, aphids, slugs, weevers, cutworms, and cabbageworm larvae.

These pests are attracted to the soft, tender leaves of the bok choy plant and will munch on them relentlessly if given a chance. The holes they leave behind will be small and ragged, and the leaves will eventually turn yellow and die if the infestation is not controlled.

You may not even know pests are present as they often feast at night when you are not around to see them. Try to inspect your bok choy before bed or first thing in the morning to catch them in the act.

If you see any pests, you will need to take action to get rid of them. Read on for some tips on how to do this!

How to Keep Pests Away From Bok Choy Leaves?

To treat the current infestation, you will need to remove the pests by hand or with a pesticide. For caterpillars and other crawling insects, simply pluck them off the plant and dispose of them far away from your bok choy.

To get rid of them for good, neem oil is a great natural pesticide that will kill caterpillars, aphids, and other pests. It’s a natural, non-toxic way to keep your plants healthy and pest-free!

The best way to keep pests away from bok choy leaves is to prevent them from getting to the plant in the first place. This can be done by creating a physical barrier such as a fence or netting around the perimeter of your garden.

You can also try using traps, such as yellow sticky traps, to catch and kill pests before they have a chance to eat your bok choy leaves. If you do find pests on your plants, you can pick them off by hand or blast them with water from a hose.

Another way to keep pests away is to encourage predators such as ladybugs, lacewings, and parasitic wasps into your garden. These helpful insects will feed on the pests that are eating your bok choy leaves!

What Else Can Cause Holes in Bok Choy?

Pests are not the only things that can cause holes in bok choy leaves…

Fungal Disease

If you live in an area with high humidity, your plants may be susceptible to fungal diseases such as powdery mildew or downy mildew.

These diseases will cause the leaves of your bok choy to turn yellow and develop brown spots. The leaves will eventually die and fall off the plant if the disease is left untreated.

Fungal diseases are difficult to control, but you can try using a fungicide to get rid of them. Again, neem oil is a great natural option that will kill the fungi without harming your plants.

You can also try to prevent fungal diseases from happening in the first place by increasing air circulation around your plants by thinning them out or pruning them back.


Holes in bok choy leaves can also be caused by physical damage. If you see large, clean-cut holes in the leaves of your bok choy, it is likely that an animal has been nibbling on them.

The most common culprits are rabbits, deer, and groundhogs. These animals are attracted to the tender leaves of the bok choy plant and will eat them if given a chance.

You can keep these animals away by erecting a fence around your garden, or by using repellents such as predator urine or soap shavings.

Should I Prune Bok Choy Leaves with Holes?

Pruning seriously damaged leaves is a good way to prevent the spread of pests and diseases. It also allows the plant to focus its energy on growing new, healthy leaves.

To prune bok choy leaves, simply cut off the damaged leaves at the base of the plant. Be sure to dispose of them far away from any other plants or gardens to prevent the pests from spreading.

Pruning bok choy leaves will not solve the underlying problem of pests, but it is a good way to keep the plant healthy while you work on getting rid of the pests for good.


In conclusion, it’s likely that pests are responsible for the holes in your bok choy leaves. To get rid of them, you will need to take action to remove the pests and prevent them from returning.

Try using a natural pesticide such as neem oil, or creating a physical barrier around your garden. You could also encourage predators into your garden to help keep the population of pests under control.
