Oh, I LOVE streptocarpus. I have 4 of them in my office and have never had a problem with them. I find them easier than African violets, which I tend to overwater. I use a regular potting mix for indoor plants and they have filtered light all year. Of course, I am in the PNW coastal area, so winters I leave the blinds totally open for them. In the summer I get full sun in the windows, which they cannot take, so I close the blinds almost all the way. Truly, they do extremely well. I water them when they get totally dry, but not bone hard, if you know what I mean. When I water, I always use a diluted fertilizer product in the water and they bloom all the time that way. I have to do it the easy way, since it's my office, so I use the liquid shultz fertilizer that has a dropper for measurement. I generally do about 1/2 strength. Probably the same stuff Willow uses. I water at the soil level or from the top because that's easiest for me to do. I've never noticed that the leaves cause any trouble when water gets on them. Also, I keep the plant tidy and don't let dead or shriveled leaves stay on it.
My pink one I've had for many years. I did notice that when I divided it the divisions were slow to establish. I don't think it appreciated that at all.
