How do I water my terrarium?

Your moss will be happiest if you use filtered water from a fridge or water bottle.

Give 2-3 sprays with included mister every 3 weeks (only if dry). Resist the urge to overwater. Less is more!

The lid in your jar allows water to cycle itself within your terrarium and retain proper humidity levels, so be sure to leave it on otherwise. You do not want to see more than a little bit of moisture on the interior glass. If excess water droplets build up, there’s too much warmth or water in your terrarium. Remove the lid to evaporate, then replace. Too much water can lead to mold, gross!

There should come a point where your terrarium doesn’t look dry or too wet - this is the sweet spot. Even when you’ve reached this terrarium bliss and don’t need to mist as often, it’s still important that you briefly open the lid every few weeks to allow fresh air in.

What kinda light does does moss need?

Keep your terrarium out of direct sunlight - this can cause too much humidity. Although most varieties of moss thrive in shade outdoors, in an indoor terrarium they do best in bright artificial light or indirect sunlight. Shady spots indoors are okay too, but if your moss starts to turn brown, try moving it to a spot with more light.

How do I prune or replace my moss?

Just like with any live plants, it’s normal for some areas of your terrarium to thrive and others to need trimming or perhaps replacement.

Trim away any pieces that are getting too long (nice work!) to promote fuller re-growth.

For replacement of larger pieces, you can purchase moss from me here. To remove moss from your terrarium, you can use a sharp knife to slowly cut out a portion and pull it out. Then fit the new moss into the space in your jar, lightly pushing it into place.

Help! My moss is turning brown.

There are several factors that could be causing this.

First, you’ll want to reset the moisture level in your terrarium. Remove the lid and allow water to fully evaporate, then mist your moss 2-3 times and replace the lid.

Moss can also turn brown if you are using tap water instead of filtered water (tap water can have too much chlorine).

Or your moss could also need more light - try moving your terrarium closer to a bright indoor light or spot with indirect sun.

I see mold…

You may have heard that moss terrariums are basically indestructible, but over-watering can be their downfall by causing mold.

If you see wispy white cotton-like growths, try wiping them away with a paper towel. If the mold is successfully removed, reset the moisture level in your terrarium by removing the lid and allowing water to fully evaporate, then mist the moss 2-3 times and replace the lid.

If the moldy spot is thicker and you can’t wipe it way, cut off and remove the moldy moss using a sharp knife. It’s okay to carefully pick up the moss as it does not have traditional roots. If you do not remove the moldy pieces, the mold will spread. See replacement of moss two questions above to fill your empty spot back in with some healthy new moss.
