What causes holes in cactus?

Overwatering

To elaborate further on these, over watering would be one of the most common reasons to have holes in cactus. 

This is quite visible during winter especially when the leaves cannot absorb the moisture from the soil. As you may know already, the moisture absorption is quite slow when compared to summer. Besides, it would make favorable conditions for other bugs and pests’ types to invade the cactus.

Lot of plants 

Additionally, if you plant cactus in too compact a location, it will also cause the cactus leaves to form holes. For example, if you put two or three cacti in just one planter, it would lead to holes in cactus.

Literally if the other plant is having spikes or thorns, they would damage the other cactus and form holes in the leaves. So, to sum up, less spacing may also cause the cactus to form holes in leaves.

Lack of sunlight

In addition to these, lack of sunlight also would also result in holes in cactus leaves. If you have cultivated the cactus in your house, make sure that they can gain sufficient sunlight. 

Having said that, the required sunlight level would vary depending on the cactus species. Hence you need to expose them for proper sunlight depending on that. 

Generally speaking, cactus need to have at least 5-6 hours of full sunlight preferably in the morning hours. So, failing in they would tend to develop holes in the plant leaves. On the other hand, too much heat would also make them form holes in the leaves too.

Insects

Finally, the breeding of the insects and pests may also cause holes in cactus. For example, grease mite, snout weevil  have a tendency to breed on the cactus and ultimately it would result in cactus holes in the leaves. 

It is important that you rectify issues at the very moment you spot unless it would be a major problem and create further severe repercussions. Further chances are that you may even lose your precious cacti.
