WOW chelle you da man.
Thank you, Thank you. You should write that up as an article.
I have never had these flower and survive even one month in the summer. I was shocked it lived this long. My local nursery wanted 6.00 for them beginning of summer and then they put all their annuals on sale for 75% off in July and decided at that price I could risk another dead begonia. I could hear the plant screaming GET YOUR HANDS OFF ME, but I did not listen and gave them the couple dollars. Probably why it lived it knows I did not pay a lot for it. I just loved the dark leaves and the yellow flower it was the last one they had with those colors.
My Rex begonias I keep in a terrarium in the winter and they do great. Summer they go on the patio and get bigger.
Now I have to decide how to handle this. The big begonia in the pot I kept it barely moist all winter in the dining room warm and it did good.
Again thank you chelle for the detailed instructions.
