Cyclamen will bloom from mid-November until spring, provided conditions are satisfactory.
Temperature and Light
Cyclamen prefer cool temperatures and bright indirect light. Ideal daytime temperatures are 60-65 degrees F. with night temperatures around 50 degrees. An east window provides adequate light.
High humidity during the winter indoors is also crucial. To maintain humidity, fill a large plate or broad shallow pan or tray with water. Set the cyclamen on an inverted dish, just out of the water. Pebbles could be placed in the plate, pan or tray with the pot sitting on the pebbles.
Plants prefer to be kept moist. Most are planted in a peat moss soil that dries quickly. Plants can wilt quickly. Make sure pots have drainage holes. If not, be sure to repot them into a container that can drain. Avoid watering the crown or center of the plant. Fertilize once or twice a month with a complete liquid fertilizer.
Bud aborting or yellowing leaves result from hot and dry conditions, lack of water or insufficient light. Check all these factors if these signs begin to show.
Storing and After Care
After flowers start fading, gradually withhold water. When the foliage is withered, remove the “bulb” (tuber) from the soil, clean off all soil from it and store it in dry peat moss or vermiculite in a plastic bag at about 50 degrees F. Replant in good potting soil in May or June, keeping the upper half of the tuber above the surface. Grow the plant in a cool, bright, protected spot outside, with partial shade during the hottest part of the day, and with the pot sunk in a bed of moist peat moss.
Water adequately and feed about twice a month with a complete liquid fertilizer. Bring indoors before cold weather, and provide full sun and the temperatures suggested above.
