Hi Bindi
African violets are fussy.
Dont ever feed them. Keep them in a warm/hot place. Once the leaf has captured an insect, the leaf will blacken and die off. Keep the soil moist, but not sodden. Place the pot on a tray of pebbles, or baked clay pebbles, and water them from the bottom.Your'e doing a good job by keeping them in a group planting, as they like humidity
Only use de-ionised or distilled water, they hate tap water...too much chlorine & ammonia, as well as salt build up.
They do go into a winter dormancy period, where they look sickly, but will come back again in the spring with new leaves
In fact, I just found a site that may help

I have a pitcher palnt as well, and some sundew. Sundew are very easy to propogate from seed.
Happy carnivoring!
