Planting Instructions for Cyclamen Seeds


Cyclamen Planting and Care Guide

Quick Facts About Cyclamen

Cyclamen is a unique annual that features vibrant flowers with "backwards" petals. The blooms not only look superb, but they also have a delightful fragrance. Cyclamen only reaches a height of about 12 inches.

Planting Time

Start Cyclamen seeds indoors (recommended) 6-8 weeks before the last expected frost, or sow directly outdoors after all danger of frost has passed.

Planting Location

Cyclamen should be planted in an area of partial shade in average, moist, well-drained soil. Cyclamen is most commonly grown as an indoor potted plant, but it can survive outside as well.

How to Grow Cyclamen

  • These seeds benefit from first soaking in tepid water until swollen (about 24 hours).
  • For indoor planting, surface sow seeds into trays or small pots filled with a seed starter mix.
  • If sowing directly outdoors, first prepare a seedbed by removing weeds and breaking up soil.
  • Surface sow 2-3 seeds per plant, then lightly cover with compost or vermiculite.
  • These seeds need darkness to germinate, and are best kept in a dark, cool area until sprouted. Keep seeds moist and at a temperature of 60F degrees until germination. Germination is erratic: Under proper conditions, seeds should germinate in 1-2 months.
  • Once seedlings have a few sets of true leaves, thin to the strongest seedling and transplant outdoors spaced 10 inches apart, or into individual containers.
  • Before transplanting seedlings into the garden, it's essential to "harden them off". This involves acclimating young plants to outdoor conditions by placing them in a sheltered outdoor area for about a week. Initially, shield them from strong winds and direct sunlight. If there's a risk of frost overnight, either cover the plants or bring them indoors, then return them outside in the morning. This hardening off method helps strengthen the plant's cell structure, minimizing transplant shock and sun damage.

Care And Maintenance

  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
  • Mulches play a vital role in preserving soil moisture and ensuring consistent soil temperatures. When it comes to annuals, using organic mulch made from shredded leaves not only enhances the appearance of the bed but also enriches the soil as it decomposes over time. Remember to keep mulch away from the plant stems to avoid potential rot issues.
  • Water plants regularly until established to keep soil consistently moist, but not soggy.
  • Cyclamen's active season is roughly from September through April. During this time, apply a half-strength liquid houseplant fertilizer.
  • These plants will go dormant during summer, but if kept cool (primarily by growing indoors), they can remain active throughout the warm seasons.
