Cyclamen Growing Calendar Month-by-Month Care and Bloom Guide

Cyclamen Growing Calendar | Month-by-Month Care & Bloom Guide

Cyclamen are one of the few flowers that thrive in the cool months when most gardens rest. Knowing exactly what to do each month—from sowing to dormancy—helps you enjoy vibrant color and healthy plants all year long.

This month-by-month guide walks through every stage of the cyclamen life cycle for both home gardeners and nursery growers.

🌱 January–February | Prime Bloom Season

  • Cyclamen are at their peak bloom indoors and in cool greenhouses.

  • Keep day temps near 60°F (16°C) and nights around 55°F (13°C) for longest flower life.

  • Water from below, never soaking the crown.

  • Deadhead faded blooms to encourage new buds.

👉 Ideal time to photograph or showcase Cyclamen Super Serie Dragon varieties — they’re stunning mid-winter performers.

🌿 March–April | Late Bloom & Light Feeding

  • As blooms fade, continue gentle watering until leaves begin to yellow naturally.

  • Start reducing fertilizer — about 100 ppm N every 2–3 weeks.

  • Move pots to a cool, shaded location to prepare for rest.

If growing in containers, check for pests like cyclamen mites or aphids before dormancy begins.

🌞 May–June | Dormancy Begins

  • Leaves yellow and die back — this is natural dormancy, not decline.

  • Stop watering completely once foliage has dried.

  • Store pots in a cool, dry spot around 50–60°F (10–15°C) with good airflow.

  • Keep bulbs shaded and dry until late summer.

💡 Pro Tip: Never discard “dead” cyclamen — they’ll regrow from their tuber next season.

🌤️ July–August | Rest & Reawakening

  • Begin checking for new buds or small shoots.

  • When growth appears, move to bright indirect light and resume light watering.

  • Repot if needed into fresh, well-draining mix.

  • Maintain 65°F (18°C) and moderate humidity to encourage new leaf growth.

🍁 September–October | Active Growth & Seed Sowing

  • Time to sow new cyclamen seeds for winter crops.

  • Germinate in darkness at 65–68°F (18–20°C) with consistent moisture.

  • Established plants benefit from a balanced liquid fertilizer (20-10-20 at 75 ppm N).

  • Increase airflow as temperatures cool — this prevents Botrytis and leaf issues.

❄️ November–December | Bud Formation & Cool Blooms

  • Buds begin forming under cooler, bright conditions.

  • Maintain temps near 60°F (16°C) and avoid overwatering.

  • Flowers begin opening again just in time for winter color displays.

  • Rotate pots weekly for even light exposure and compact growth.
