Cactus Terrarium Care Guide

How do I water my terrarium?

If you want to kill your cactus, overwater it. This is the most common reason people fail with this plant. Instead, allow your cactus to get bone-dry between watering. Water about every 3 - 6 weeks, depending on the humidity of your environment, giving it a drink when the soil feels completely dry to the touch.

How much light does my terrarium need?

Unsurprising for a desert plant, in order to be healthy, the cactus wants lots of light and thrives when it’s bright and the temperatures are warm. If the light is too low, the cactus will go dormant rather than growing or flowering. If you keep the cactus in an office or someplace with less light, give it a sunny “vacation” every so often.

What do I do if a plant in my terrarium dies?

If your plant dies within 7 days of purchase, we will replace that plant at no charge to you. Just get in touch with us over text, email, phone, or social media within that 7 day window and include a photo of your plant and then you may come in at your convenience for your replacement.

If it has been more than 7 days and your plant has died, remove the plant from your terrarium and be sure to fill its place with another plant or a heavy trinket like a rock or figurine to avoid having the remaining plants revert to a territorial growth habit.

Please feel free to get in touch with us at any point about your plants! We are happy to help diagnose or troubleshoot any issues you may have, or even just see how fabulous your creation is looking!

Do I need to fertilize my terrarium?

All plants benefit from a healthy bacterial community in their soil. Keep your cacti happy by putting some bacterial inoculant into the soil when you water.

Does temperature matter?

Because cacti are desert plants, they are not accustomed to having to deal with the cold. As such, they will not respond well to it.

With this in mind, keep them away from cold windows, vents, or other areas where the temperature may drop below about 50 or 60 degrees. If you would want a jacket where they are, it is too cold for them.

As for heat, they’re much more resilient - but don’t put them on the stove!
