Terrarium FAQs and Care Instructions

What is in a terrarium?

A terrarium is a sealable glass container that can be used to grow and display small plants. It typically contains soil, moss, and pebbles, and may also include small rocks, twigs, bark, and other decorative items. Plants suitable for terrariums include ferns, mosses, succulents, and other small plants that can thrive in humid, enclosed environments.

How long do terrariums last?

Terrariums can last for many years with proper care. However, the lifespan of a terrarium can vary depending on its size, the environment it is in, and the type of plants or animals that live in it.

Why do terrariums not need air?

Terrariums do not need air because they are self-contained ecosystems that rely on the balance of their own internal environment. The plants in the terrarium produce their own oxygen, which is balanced out by the animals living in it that consume oxygen. The terrarium is also sealed, so the oxygen produced is not lost to the surrounding environment.

What are the best practices for maintaining my terrarium?

To keep your terrarium thriving, ensure it receives indirect sunlight, maintain proper humidity levels, and water it sparingly. It's essential to monitor the plants for any signs of overwatering or mold.

How often should I water my terrarium?

Generally, you should water your terrarium every 2-4 weeks, depending on the humidity and temperature of your environment. Always check the soil moisture before watering to avoid overwatering.

Can I use regular potting soil for my terrarium?

It's best to use a well-draining soil mix specifically designed for terrariums. This helps prevent waterlogging and promotes healthy root growth.

What types of plants are suitable for a terrarium?

Small, low-maintenance plants such as succulents, ferns, and mosses are ideal for terrariums. Choose plants that thrive in similar light and humidity conditions for the best results.

How do I clean my terrarium?

To clean your terrarium, gently remove any debris or dead leaves with a soft cloth or brush. Avoid using harsh chemicals; instead, use a mixture of water and vinegar if necessary.

What should I do if my plants are growing too tall?

If your plants are outgrowing the terrarium, consider trimming them back to maintain the desired size. You can also repot them into a larger terrarium if needed.

Can I add decorative elements to my terrarium?

Absolutely! Adding decorative elements like stones, figurines, or colored sands can enhance the aesthetic of your terrarium. Just ensure they do not obstruct the plants' growth or health.

How do I know if my terrarium is getting enough light?

If your plants are stretching towards the light or losing their vibrant color, they may not be getting enough light. Adjust their position or consider using a grow light if necessary.

Is it normal for my terrarium to have condensation?

Yes, some condensation is normal in a closed terrarium as it helps maintain humidity. However, excessive condensation may indicate overwatering or poor ventilation, so adjust accordingly.
