Only water your terrarium with a small amount of water every couple of weeks. Do not overwhelm the plant by soaking it with water, as the plant will become too wet and die. Give a small to medium sized terrarium a few ounces of water at a time, allowing it to dry completely in between waterings.
One may also ask, do succulent terrariums need water?
Succulent Terrarium Care
Your succulent garden won’t need to be watered very often. Wait until the soil is nearly completely dry before you water. Use tap water that has been off gassed or purchase purified water. Succulent terrarium care is pretty much the same as care of succulents in a pot.
Consequently, how do I know if my terrarium has enough water?
3. A completely enclosed terrarium requires little or no watering but when in doubt, always water less. If you can see water within the pebbles at the bottom, there is way too much water. Be careful that the plants do not become too dry because they will wilt.
Should you mist succulents?
Full grown succulents don’t actually like to be misted. They thrive in arid climates, so when you mist them, you are changing the humidity around the plant. This can lead to rot as well. Use misting for propagation babes to lightly provide water to their delicate little roots.
The best way to tell whether your succulent is being over or underwatered is by the appearance of the leaves. An underwatered plant will have wrinkly, shriveled up leaves whereas an overwatered plant will have soft, mushy, almost translucent leaves.
Your terrarium plants can start dying due to too much light and/or heat. … Signs of too much light and heat are dry dead leaves. Also, make sure not to place your terrarium near a hot radiator. Too much heat can quickly kill your plants in the terrarium.
Succulents roughly need at least four to six hours of sunlight to grow properly. Because of the reduced light indoors, plants mature much more slowly. Given their highly adaptable properties, succulents will survive for quite some time in the shade or low light but will not thrive.
In theory, a perfectly balanced closed terrarium – under the right conditions – should continue to thrive indefinitely. The longest known terrarium lasted on it’s own for 53 years.
