How to Grow Cyclamen Indoors
There are various types of cyclamen, including hardy ones that'll grow well in your garden. However, if you bought or were gifted a flowering cyclamen in winter, then chances are that it's a florist's cyclamen, one that isn't hardy.
Florist's cyclamen—also known as Persian cyclamen or Cyclamen persicum—have been bred for their colorful winter flowers, often in seasonal colors, and their intricately patterned leaves. They make superb house or greenhouse plants that flower all winter long.
Make Sure the Temperature Is Cool
Grow cyclamen in a cool room in your house, a sheltered porch or a frost-free greenhouse. Cyclamen need daytime temperatures of 55˚F or 13˚C, and nighttime temperatures of 43–59˚F (6–15˚C). If you grow cyclamen in house temperatures with a daytime temperature of 68˚F and a nighttime temperature of 50˚F, then they'll die a slow death.
Are Cyclamen Annuals or Perennials?
Many people come to the mistaken conclusion that cyclamen are annuals because they kill them slowly by applying too-high temperatures. If you've bought your cyclamen as a seasonal table decoration, then by all means place it on your table when you entertain. But afterwards, do remember to return it to its cooler position.

Keep Out of Direct Sun
Grow cyclamen in filtered, dappled light, not direct sun. Full sun can be too harsh and drying for this plant.
Allow to Dry Out Between Waterings
Cyclamen need to dry out completely between waterings, so wait until the top inch of your plant's mix is dry before watering. Once every two months, apply a half-strength, soluble fertilizer.
Cease Watering When Dormant
Another important consideration when growing cyclamen is that they are summer dormant. Around about April, your cyclamen will begin to tie back, losing its leaves. This is quite normal, and it's the trigger to reduce watering. Once all leaves have disappeared, you should cease watering your cyclamen completely. If you water your cyclamen when it's dormant, it will rot.
Store for the Summer
Once your plant has gone dormant, keep it in a cool, dark place for summer until it starts back into growth in autumn.
