Hi All,
I have just germinated a desert rose seed, the seedling is about 3"
tall now with 2 leaves on top. I still have it in my propagator.

At what point would it be OK to remove it from the propagator and
transfer to a windowsill?

Blimey! A miracle! In my experience, that form of gypsum never
germinates, but just quietly crumbles away on the mantelpiece.

Mike.
