Brian asked "Can someone advise on treatment of Begonia grandis subsp. evansiana propagules. Do I "sow" now or spring or store, how, how deep etc."

Here in the greater Washington, D.C. area, we would just scatter them where we wanted them. In this area the plant will slowly spread and eventually form broad masses.

I have no idea what it needs in other climates.
