So I was browsing the house plant rack at wally world and saw some Begonia rexs. Most were piles of mush due to over watering. But about 2 still had leaves and I bought the best looking one. It even has a few flower buds.
I have killed two or three in the past many years ago by potting them in pure potting soil. This is before I learned most of what I know about plants today.
This time I planted it in a gritty mix. How often should I water it and how much light does it need?
