Hi guys, I got this plant (I believe she is a Begonia) from an outdoor market over a month ago. Since then I have repotted her and water her once every other day/ give or take a couple days. Her soil does not retain water well and she has always had dry leaves, but now her flowers are starting to turn black. My room gets direct sunlight everyday for a couple hours. What should I do to care for her? She seems to be getting worse and worse.
