i was given a propagation of my friend’s rex begonia. she’s been in water for about five days, and i’m starting to wonder when she’ll grow roots. i’ve included a picture of what i thought was the start of a root, but now i’m not sure. i’m keeping her in a dome to up the humidity, will that make her root faster? she’s in an east facing window that gets about 4-6 hours of sunlight per day.
