The resilience of these miniscule Sinningia pusilla seedlings is incredible!
So that day, March 4, I separated and ever so daintily attempted to "plant" them. (Yeah, you try planting seedlings that are a sixteenth of an inch tall and no discernible roots!) Didn't dare mist them, as they would have lost themselves in the soil; so, I bottom watered, and put little domes over the "pots". The tweezers are there for size comparison. Mama is on the left.
And they have already grown! No hint of true leaves on March 4, but now, March 8, see here:
(That paper with the millimeter squares is the same tiny white rectangle in the first pic.)
