Hosta in a terrarium--possible?
For a couple of days I've been turning this idea over in my mind, since I got the dwarf-mini-tiny hosta and they look so cute. What would make it NOT work?
I was looking especially at Golden Tiara, which has a beautiful low shape and leaves which glow. It looks like a "real" hosta unless something in the photo gives away the actual miniature size of the plant. Here it is.
I have one terrarium set up now in a huge lidded and footed glass snifter. It's been healthy for almost two years, with only occasional additional moisture or tipping the lid to get rid of condensation.
Surely there would be no pest problems like slugs or cutworms or voles? A bed of activated charcoal could keep it sweet, not souring. Maybe some larger pebbles as a bottom layer. How about a smaller aquarium with a lid too?
A rectangular container would make it possible to grow more than one hosta, to bank the soil on one side for a good slope and a bit of landscaping.
Okay, the problems...the nature of the hosta to go dormant. If you do not interfere with the plant's growth cycle, couldn't you put it in an unheated room for the winter? And also, couldn't you keep it indoors without concern for too much heat, if you are in an air conditioned office or home, where they keep it freezing cold. An Ott light in the lid (if an aquarium) could give it as much light of the proper wave length too.
Of course, I'm not that detailed about my projects, I just do them and tinker to adjust them as I go. If you wait until everything is perfect, you'll never get around to doing it.
Has anyone grown hosta in a terrarium setup? Or have you known anyone to do so? I think it would be a great way to feature a dwarf or mini plant during its normal growing season, and figure out later how to transition to a dormant period.
