MOSS TERRARIUM CARE

Q: WHAT IS A TERRARIUM AND HOW DO I CARE FOR IT?

A:
Terrariums are living, miniature ecosystems in closed glass vessels. Moss gets nutrients from humidity in the air and slowly grows (pretty sweet!).


Q: HOW OFTEN SHOULD I WATER MY TERRARIUM?

A: Mist lightly every three weeks with filtered water (only if dry). The lid on 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, remove the lid to evaporate, then replace. Too much water can lead to mold - yuck! Moss doesn't have traditional roots and takes in nutrients from water on its surface leaves. Resist the urge to water as you would a houseplant, since there is nowhere for stagnant water to evaporate to in a closed jar. Less is more (dream plant, amiright?). ♥

Q: SHOULD I PUT IT ON A WINDOWSILL?

A: You want to avoid putting it in direct sunlight - this can lead to too much humidity, and mold development. However, although most varieties of moss thrive in shade in their natural habitats, when indoors they grow best in bright artificial light (great for offices!) or indirect sunlight. 

Q: HOW DO I PRUNE/REPLACE MY MOSS?

A: Just like with any live plants, it is 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 gather it outside yourself (think shady spots by bodies of water, but no city/state parks or private properties!) or you can purchase a touch-up pack from me here.

If you are moss-hunting yourself, be sure to get a little bit of the substrate the moss is attached to as well. Moss doesn't have roots, it has threadlike “rhizoids” that anchors it to surfaces, so no worries about digging only 1/2” to 1” underneath it. You may wish to spray with a de-bugger such as Organicide if you’re not a fan of insects. Once you have your moss simply put your piece into the space in your jar, lightly pushing it into place. 

Q: HELP! MY MOSS IS TURNING BROWN.

A: There are several factors that could be causing this. First, you'll want to re-set the moisture level in your terrarium as it's possible it's too high. Remove the lid and allow all water to fully evaporate, then mist your moss lightly 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. 

Q: I SEE MOLD...

A: 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 to wipe them away with a paper towel. If the mold is successfully removed, re-set the moisture level in your terrarium by removing the lid and allowing water to fully evaporate, then misting the moss lightly and replacing the lid. If the moldy spot is thicker and you can’t wipe it away, cut off and remove the moldy moss using a sharp knife or scissors. It is okay to carefully pick the moss up as it does not have traditional roots. If you do not remove the moldy pieces, the yuckiness will spread. See replacement of moss two questions above to fill your empty spot back in with some healthy new moss.
