Luckily, pests can be prevented.







Red spider mite

Nematodes, etc.

The appearance of mealybug eggs on the spines’ tips, or an ant, means they are sucking the plant’s sap and its life.

In this regard, immediate treatment requires and thorough washing or spraying of an effective insecticide. You must remove the pests even that plant is dormant.


Mealybugs won’t stop bothering your plants and eat your plant during wintertime. They will harm your plant anytime.

If you want a less toxic solution, you can soak the plant into soapy water overnight (a dish detergent, it works great for this purpose).

Not giving attention to mealy bugs, these horrible insects will start spreading throughout a collection of plants very fast and then, sadly, you will lose those plants.

Once the mealybugs have taken hold, fighting them off and keeping your plants is not an option – you will lose your battle.

Cacti are vulnerable to rot because of their water-filled fleshy tissue. But, with proper care, rotting will be prevented. Rot typically starts from the bottom and goes up.


Sometimes, the rot appearance is visible on the upper part of its stems, having pale yellow or white-toothed petals and a darker or reddish central line of 1.5 cm in its length and diameter sometimes.

The roots don’t rot off first. But in rare cases, it may rot starting higher up. This could happen when you overwater the plants

The appearance of rot varies from black to red. The affected parts are mushy, slimy and the smell is bad. You’ll know quite quickly if your plant is diseased because it is visible in spiny plants.

If this condition occurs, there’s nothing you can do to save your plant.

When your cactus is placed in a dry environment, it can still get rot if it has been damaged.

Don’t be deceived, it is possible that the top of the plant may look fine, but underneath, it is completely rotted, and survival is no longer possible.

Fungal Attacks

Fungal attacks are also common. This can be recognized in its black appearance or rust-colored spot, surrounded by dried brown sections on its stem. But this kind of case doesn’t occur on all cacti – mostly on epiphytic cacti.
