Epiphytes are plants that grow on other plants or trees and receive nutrients and water from the air, rain and decaying matter around them. In other words they are perfect terrarium guests, loving the humidity created within a closed glass vessel. They make great houseplants due to their minimal water and soil requirements and are excellent candidates for mounting.
Mounted epiphytes in a terrarium are cared for much like their planted counterparts. Here's how to do it.
A few of the plant types and genera that may be included: Jungle cacti (Rhipsalis, etc.), Ferns, Philodendron, Hoya, Nepenthes, Syngonium & Bromeliads.
High humidity is ideal. Regular misting with a spray-bottle will help raise the humidity. Ideally you want to see sections of condensation build up on the glass within your vessel. Keep an eye on the moss. If it starts to look dry, open the cloche and spray with a mister. I usually do this on a weekly basis. Use kitchen roll to absorb any water on the flat wooden base.
Remove at soon as you get a hint of the stuff... it has a tendency to spread.
Place in bright indirect light, avoiding direct sun.
If desired, feed your mounted epiphytes with an epiphytic fertilizer monthly through spring and summer. This may encourage blooming. Take care not to over-feed.
