Caring for your terrarium is easy – They actually thrive on neglect…
The main key to success, first and foremost is to provide enough light. Your terrarium needs about six hours of bright indirect light each day, but never direct sunlight. Feel free to move it around to accomplish this need.
A second key is never to over-water! You’ll know when it’s time to water; the soil no longer feels moist to touch. Watering frequency depends on conditions; expect up to several months between watering. There are moisture reading probes available that are an efficient, low cost tool. I suggest giving one tablespoon of water to a palm of you hand sized patch of moss every 2 months and plants 1 to 2 tablespoons every 6 months to a year.
Since terrariums are lidded, condensation is expected. This condensation process recycles as it’s own rainfall. If you see an abundance of condensation; that lasts constantly for more than 2 hours in a day, simply set the lid ajar until it clears.
With clean hands, trim away and remove any unwanted, yellowing or dead growth. Carefully prune when the plants grow too large. No need to fertilize since you don’t want to encourage growth in your mini environment.
Now you’ve Got it!
