In this article, we'll answer these questions and more, so keep reading to learn everything you need to know about bump on a cactus.

What Causes Bumps on a Cactus?

The bumps on a cactus are usually caused by specialized structures called areoles. Areoles are small, round, cushion-like areas on a cactus where spines, flowers, and new branches emerge.

Sometimes, areoles can become swollen, resulting in the formation of bumps or lumps on the cactus. This swelling can be caused by several factors, including:

1. Sunburn

Just like humans, cacti can get sunburned if they're exposed to too much direct sunlight. When a cactus gets sunburned, it may develop blisters or bumps on its surface.

To prevent sunburn on your cactus, make sure to place it in a spot that gets partial shade during the hottest part of the day. You can also use a shade cloth or umbrella to protect your cactus from the sun's rays.

2. Insect Infestation

Some insects, like scale insects and mealybugs, feed on cacti and can cause bumps to form on the plant's surface. These bumps are often accompanied by waxy or cottony material.

If you suspect that your cactus has an insect infestation, you should isolate it from your other plants and treat it with an insecticide spray or soap.

3. Fungal or Bacterial Infection

Fungal and bacterial infections can also cause bumps to form on a cactus. These infections usually occur when the cactus is kept in humid or wet conditions for too long.

To prevent fungal and bacterial infections, make sure to water your cactus sparingly and avoid getting water on its leaves or stem.

Types of Bumps on a Cactus

Not all bumps on a cactus are the same. Here are some common types of bumps that you might see on your cactus:

1. Areoles

As we mentioned earlier, areoles are small, cushion-like areas on a cactus where spines, flowers, and new branches emerge. They are usually raised and slightly darker than the surrounding skin.

2. Spine Cushions

Spine cushions are similar to areoles but are larger and more pronounced. They are covered in spines and can be found on the stem of some cacti.

3. Calluses

Calluses are thickened areas of skin that form on a cactus's stem. They are usually caused by injury or damage to the plant's surface.

4. Galls

Galls are abnormal growths that can form on a cactus as a result of insect infestations or injuries. They are usually round and can range in size from a pea to a golf ball.

How to Take Care of a Cactus with Bumps

If you have a cactus with bumps, there are a few things you can do to take care of it:

1. Keep it out of direct sunlight

As we mentioned earlier, too much direct sunlight can cause sunburn on a cactus and lead to the formation of blisters or bumps. Make sure to keep your cactus in a spot that gets partial shade during the hottest part of the day.

2. Water sparingly

Cacti are adapted to survive in arid conditions and don't need much water to thrive. Overwatering can lead to fungal and bacterial infections that can cause bumps to form on a cactus's surface.

3. Use well-draining soil

Cacti prefer well-draining soil that doesn't hold onto moisture for too long. You can use a pre-made cactus soil mix or make your own by combining sand, perlite, and potting soil.

4. Monitor for insect infestations

Keep an eye out for signs of insect infestations on your cactus, such as mealybugs, scale insects, or spider mites. If you notice any of these symptoms, isolate your cactus from your other plants and treat it with an insecticide spray or soap.
