I recently bought a Cyclamen persicum, and some of the leaves have started to turn yellow. This is my first time taking care of one, so I'm not sure what is normal and what isn't. I have a south facing room, with the Cyclamen roughly in the middle. My room gets lots of sun, but I make sure that the Cyclamen is never directly in the sun. I put water in the bottom tray when I feel the top of the soil drying out (about once every two days), and use water that is a room temperature and mixed with seven drops of a 10-15-10 liquid fertilizer (according to the directions on the box). It was recommended that it likes being cooler at night, but since I can't put it outside I've been sitting it on my windowsill. I would really appreciate any advice on how to grow this type of plant and keep it healthy! Thank-you!
