I was bought 6 streptocarpus plug plants in mid march. We potted them up as instructed, and have them in a light cool room. They just aren't growing and they look just the same as they did 2 months ago. HELP.

These aren't exactly super fast-growing plants, so if the light and soil conditions aren't "just right," it's not surprising that the plants don't appear to be growing. They also may simply have been in dormancy and are getting a slow start on the growing season. Double-check your watering schedule, soil mix and lighting situation.
