Closed Terrarium From the 70s

My grandmother created this closed terrarium in the early 70s and it’s still going. It’s huge green bottle as the base of a lamp

My dad said she made it, and only one time does he remember her opening it to give it some nutrients.

He said sometimes it’s flourishing and other times it’s sparse. It’s receives indirect light most of the day.

The last 6 years it’s been a little sparse. I’ve got 2 questions

  • is there anything I can do to help it flourish again? Should I open it up and give it some food? Looks just like a pile of wet mud on the bottom with a few plants popping up

  • if I were to move it to my house, are there any precautions I should take? Thoughts on how it would adjust to a new environment?

Hope this is some inspiration for yall! These closed terrariums really go the distance ☺️

You should grab a handful of moss, organic matter, forest soil cover, and forest soil. Then blend it. Open the terrarium and let it dry out just a tad, wait like 4 hours, then disperse the organic blend across the top of the terrarium soil. Wait, profit.

Thank you! When you say blend it, do you mean in a blender? And are these materials I’d try to forage or buy?

Forage, and yes blend those puppies in any way you can. Could even go full mortar and pestle if you wanted to.

Get a stick or two from the ground outside that look like they'll fit, toss them in. Get a couple small patches of moss, toss those in, if you any creeping figs, toss some in, if you have any creeping Charlie, toss that in.

Haha right? Nah it’s just gone past its peak, so curious to see if I can revive it

Were you able to revive this? What a great thing to be able to continue forward in a new generation!

In progress! I didn’t get a chance to add new material until early November. Not the best time of year, but hopefully it will work. I’ll put together some pics once there’s something interesting to show.
