Why Can Succulents Grow in Sand?

Succulents’ natural habitat in the wild are often environments that would often be uninhabited by other plants. Most succulents come from dry areas like deserts and semi-deserts. Some originate from mountains and others, rain forests. These plants are extremely hardy and adaptable that they are able to survive conditions that are normally too harsh for other plants, such as high temperatures and low humidity.

Due to their harsh natural habitats, succulents are made more adaptable to less-than-ideal conditions. This is why succulents are able to survive in the sand for a longer period of time compared to most plants which may not even last a couple of days.

Another determining characteristic of succulents that enable them to survive without soil is their ability to store water. Succulents typically store water in their leaves, stems, and roots. They can adapt to very dry conditions. They do not require frequent watering and can survive without a moist soil.

Besides, unlike most other houseplants, succulents can survive without a highly organic medium. This means that they do not require soil that is rich in nutrients. However, in order to thrive, they do require a certain amount of organic matter in their growing medium.

Therefore, although succulents can survive in soil-less medium such as sand, it is not an ideal condition in which they can thrive. So while succulents planted in these terrarium look stunning, they are not meant to last for a long time.

Things to Consider When Growing Succulents in Sand

Although I mentioned that succulents can survive in sand, it only holds true for coarse sand. Succulents grown in fine sand will not survive well at all. Fine sand retains too much water, making it compact and the succulents’ roots unable to breathe. As an alternative, you can also get the best soil for succulents in pots, if you plan on doing any repotting.

Succulents grown in sand will not be getting enough nutrients as succulents grown in soil. Therefore, consider fertilizing the plants by adding diluted fertilizer (about ¼ to ½ strength) into the water you will use to water the plants. This way, you are providing the succulents some nutrients they need to grow.

A Good Alternative to Growing Succulents in Sand

A good alternative to growing succulents in sand is using a soil and sand mix. The large particles of sand allows water to pass through them, providing proper drainage, while the soil provides nutrients to the plants to grow.

You can use the following soil recipe:

Blend the mixture thoroughly and you will have the perfect soil mix ready for your succulents.
