I just ordered a begonia "wightii" polka dot / clown begonia.

I *think* it is a cane begonia.

I usually grow horas and orchid cactus as houseplants, so I don't jar any experience with begonias.

Questions:

I ordered a small 3 inch plant, and I would like a nice big one. How fast do they grow? Would miracle grow help, or is their a different fertilizer I should use?

How much light & water does it require?

How do I take cuttings from this plant and what's the best way to root cuttings?

Any other begonia tips would be appreciated :)
