I wouldn't waste a good block of Oasis.

If anyone wants some dried stuff to play with, I have some in the loft.
I never realised it couldn't be re-wetted, never even occurred to me til

rooting cuttings in it.

What would you do, plant out the whole block, oasis and all, once the
cutting had taken?
