Why Does Cactus Split? 10 Minutes Quick Read

Why Does Cactus Split

Why does cactus split?

Your cactus may split if they are lacking sufficient water. In other words, if your cactus spilt, it literally means the plants need water. You may come across these conditions quite often during summer.

During summer there will be extreme heat and dryness and they will try to get a sudden influx of moisture from rain, irrigation or from both of them. The dryness would make the plants cells shrink, because plants use the conserved water to make them survive.

The shrinking would impact on the elasticity of the epidermal skin cells of the plant. As they get water , the absorption starts and the cells would not be able to expand faster as they used to do. Ultimately it would make the cactus split.

Cacti are slow growing plants, and you have to put a lot of effort and a lot of time to recover them. So, if the plants have been going through hot and dry conditions for too long and if you decide to pour water on them, it will lead to cactus splitting.

Cacti are renowned for their ability to conserve water, so once they get too much water, they would tend to conserve them in the foliage. Once they try to conserve more water they would tend to expand which would ultimately make them split.

Apart from that, growing them in a too small pot may also lead to this condition. Therefore, always try to use slightly larger pots compared to the root ball of the cactus. 

Apart from that, I urge you to keep the plants in a place where the kids or any of your pets can reach the plants easily. Chances are that they may also damage the plants and make the plants split.
