passion I would remove the bottom leaves. And to put it in a plastic container cottage cheese or Marjorie with perlite and to put some holes in the bottom place . Your cuttings in the perlite. And put a clear plastic bag over-the-top put a couple of small stakes to support it. And place in a saucer with water. Be sure it has good light but not direct sunlight. Wish you luck

Thank you for the info. My cuttings are doing good. Have also started 3 Richardsiana.begonia's from some small cuttings.
