At that point it’s a Godzilla!!Angela, I’m doing that now with a B. digbyana. It’s starting to grow quite well after a few months. I did cover new roots on the surface with moss. I just water every 7 days. So far so good.
I’m not fond of the fact that when it outgrows it’s basket, you have to put the whole thing basket and all in a bigger basket. What happens when there are no more bigger baskets?
