Why Is The Succulent In My Terrarium Rotting (How To Avoid Rot)

Though it is interesting to grow long-lasting decorative or mini-plants in terrariums but several succulents rot in them due to various reasons.

In this article, we are going to shed light on some of the common reasons behind rotting succulents and how to avoid it.

The container you choose for making a terrarium should be suitable for the nature of the succulents you want to grow in it.

The container should not be closed and also have good ventilation and drainage system so that your plants can grow well in a low humidity environment.

The container you choose must be open enough to provide enough air and retain heat and moisture required by the plants you grow in it whether they are succulents, carnivorous, or air plants.

Don’t Overwater Succulents

The second most common reason for rotting succulents in terrariums can be watering the plants excessively.

Plants usually rot due to the growth of mold when they are over watered. To avoid this situation either you should not water them too much or make holes in the terrarium for proper drainage of water.

If the leaves of your succulents become soft and lose their firmness then overwatering can be the reason behind their rotting.

Plants can be too big in size: Your succulents can rot or die in your terrarium if your plants are too long than the size of your container. Longer plants may rot quickly by catching water while touching the sides of the container.
