Picotee Begonias from seed?
I am trying to grow some begonias from seed this season. I have some picotees beginning to sprout, and am waiting on a different batch of yellow tuberous begonias.
Am I correct that the seedlings need to stay inside the domed trays even after they sprout? I have read this a couple of places on the web, but everything else that I have ever grown from seed gets removed from the covered trays as soon as I see any green poking through. It makes me nervous to leave the begonias.
Should I wipe off water that accumulates on the lid regularly so they dont get dripped on?
Any advice from experienced Begonia growers would be appreciated.
