What’s good about cacti is that they are sturdy plants. They are low-maintenance plants in that even if neglected, they will thrive happy and strong. There are several containers that can hold indoor cactus plants, but one of the most widely used is a terrarium. A desert landscape in a box, a cactus terrarium is a great decorative accent. Here is how you can make a cactus terrarium.
- Get a suitable terrarium. Size is a matter of importance when it comes to terrarium. Although you can get a small terrarium at first, you have to remember that cactus plants will grow. There are some plants that will stay small, but there are others that will occupy some space. So your choice is either to get a big terrarium at once or to transfer the plants to a bigger terrarium when they all have grown. Make sure the opening of the terrarium is big enough to promote air circulation. Before planting the cacti, it is important that you first clean the terrarium. Wash it with a solution of water and bleach.
- Choose your cactus plants. The problem with growing multiple plants is that there is very little concern about their growing compatibility. There are cacti that require more water, more light, more space, while others can make do with less water, less light, and less space. What you need to do, therefore, is to choose cacti that are compatible with one another. This doesn’t mean to say, however, that you need to choose plants of the same variety and type. Although that is possible, it doesn’t make a diverse and attractive terrarium. Instead, grow cacti that have almost the same maintenance requirements. A full-sun cactus that lives together with a partial-shade cactus can somewhat be problematic.
- Prepare the soil. The soil of the cactus terrarium should be particularly suited for the soil and water requirements of the plants. The goal is to keep them hydrated without soaking their roots in water for too long. So the best option is to use sand and gravel with cactus soil. Two-inch deep gravel should form the soil base, which will promote proper drainage. On top of the gravel is a combination of soil and sand. You can buy this special kind of soil, but you can also make your own by mixing soil and sand in a 2:1 ratio. This sandy soil combination should be two to four inches thick.
- Plant the cacti. Begin planting the cacti as soon as the terrarium is ready. Carefully make holes and put each of the plants in place. The plants should be spaced appropriately. If you place them too close too each other, there won’t be enough room for them to grow.
Although cactus plants are generally low-maintenance, you should take care of them in the same way you care for other plants. This is assuming that you don’t want them to just survive, but you want them to grow beautiful and healthy. Put them under the required amount of light (artificial light will work) and water them as needed.
