What are Brain Cactus and How to Grow in 2024?

The Brain Cactus belongs to the region of Central Mexico and the family of Mammillaria Elongata. This is the reason why this cactus is sometimes also referred to as the Mammillaria Elongata Cristata.

The name brain cactus is because of its convoluted and sinuous growth, somewhat like a peculiar crest. Let me tell you a very interesting fact about its shape. The brain cactus skull is formed as a result of the damages that happen to the plant when at its tender age.

Like other succulents, the brain cactus has a peculiar center of growth which is known as the apical meristem.

The Mammillaria Elongata cactus is also sometimes referred to as the Ladyfingers cactus. The pattern of the growth is quite similar to the structure of a worm, some say it is like that of a brain and that is how the plant got the nickname brain cactus.

Are Ladyfingers Cactus and Brain Cactus same?

The answer is yes, ladyfinger and brain cactus are the same plant. Then, the question arises, why do they look different?

The answer lies in the amazing phenomenon of the plant world. It actually happened through mutation or damage.

During the initial growth phase of the cactus and succulent plant, they have some tissue known as meristematic tissue or ‘growing tip’. The main function of this tissue is to set off new cells growth in young seedlings at the tips of the shoots and form buds.

By any means, if these tissues are damaged by an insect or a natural mutation, the crest becomes deformed and shapes as a structure of the brain. Isn’t it amazing? Nature beautifies itself.

Sometimes gardeners also witness damages from insects in the apical meristem which may cause a cell mutation, but it’s rare.

If you find a brain cactus dying, there may be numerous problems like environmental conditions, fungus, bugs, and some diseases. However, if you care well, the diseases can be avoided.

This species of cactus is sensitive to red spiders. Aphids, Caterpillars, Nematodes, Slugs, and snails are also some pests that can affect your brain cactus.

You do not require a big container as the roots are shallow and an unglazed pot would be the best for its plantation.

You can use a skull painter with brain cactus that looks quite different. Many may have a different thought but a brain cactus in skull pot is very attractive.

Once you notice roots coming out of the pot, it’s probably time to re-pot the plant. Be gentle while you remove the plant from its existing pot. If you are not careful, you can hurt yourself as an adult cactus has a lot of spines.

Now, place it in the new pot and add some freshly prepared potting mix. Wait for some time before you start watering it. After 1-2 weeks start watering following a definite routine.
