Terrarium Care
What are terrariums?
They are a small, enclosed environment for certain plants. Think of it as a mini-greenhouse. The containers for terrarium gardens are typically transparent, such as glass or plastic.
There are two types of terrariums, sealed and open. Sealed terrariums have a removable lid while the open terrarium does not. Some argue that an open terrarium is not a ‘true’ terrarium!
How do terrariums work?
They are indoor gardens in a sealed container. The plants and the soil in the terrarium release water vapor – essentially recycling water. The vapor is then collected onto the walls of the vessel and trickles down to the soil. Terrariums are self-nourishing, which is why they require little maintenance, if sealed.
How do you care for terrariums?
Terrariums are low maintenance for the most part but we do have some suggestions to keep your terrarium long lasting and healthy.
If you choose to grow ferns, trim leaves to prevent them from overgrowing.
Make sure to remove yellow and brown leaves from any plants in your terrarium. This is typically a sign of disease or pest.
If you have an open terrarium, monitor for pests such as gnats or mealy bugs.
If you have closed terrarium, you may want to remove the lid every now and then to let in some fresh air.
Do you have to water terrariums?
Yes, but not as frequently as typical indoor plants. The types of plants found in terrariums tend to be hardy plants that don’t require frequent watering. Also, the greenhouse-like structure of terrariums recycles water instead of evaporating water into the ambient air with normal indoor plants.
If closed, you might be watering them (on average) once a month but this will vary depending on a variety of factors. Open terrariums benefit from being watered every 3-6 weeks. Rather than watering on a schedule, check the soil to see if and how much water your plants need.
Do terrariums need sunlight?
Most need either direct or indirect light but artificial light may also be used. There are three types of light you can provide for your terrarium.
Direct sunlight
Indirect sunlight
Artificial light
It is recommended to use fluorescent or LED bulbs. Avoid incandescent bulbs.
If you choose to place your terrarium in direct sunlight, you may want to remove the lid on a closed terrarium because it might get too hot for the plants with the lid on. Too much direct sunlight is the least preferred option.
