Does anyone have advice on how to grow angel wing begonias from seed? I received pelleted seeds from Pine Tree Garden and have started them in the new fangled "All Roots Seed Propagator" which I purchased from Gardens Alive. The seed which is very tiny is dropped into a whole in the "grow plug". Should they germinate in light or dark, because though the hole is deep for the little seed, it still gets some light?
I always had success with angel wings from seed. What I do is surface sow on top a super fine germination mix, firm but do not cover, place in a clear poly bag about 10" from grolux bulbs, and the heat mat is set to 80 degrees. I run the lights about 16 hours a day on a timer.
I do all of early annual seeds this way and some I cover and some I dont depending how much light is needed for germination.
The shorter time annuals like impatients and marigold I start in the greenhouse in early March.
Angel Wing Begonias, New Guinea Impatients, and Datura I start indoors to better control the requirements.
