Drainage

I have read that there are a few trees that do OK as Bonsai in an enclosed terrarium. I have also heard that you should not put a tree in a pot with no drainage.

My 1st question is "if you have to have drainage how does a tree survive in an enclosed terrarium"?

Second question " If you have a pot or dish you want to use for Bonsai that does not have a drainage hole would a good layer of gravel at the bottom work for drainage.

I guess one answer with solve both questions.

New to Bonsai and want to do it correctly.

Thanks for any feedback

If you are new to bonsai and want to do it right, growing in enclosed terrarium is not the right path to shose.

Bonsai is traditionally grown outdoors from locally hardy mature trees.

With that beeing said. I do grow some mangrove trees in a tropical terrarium. I use leca clayballs in the drainage layer and empty it with a small hand pump twice a week. Seems to work fine for mangroves.
