    When does Red Campion flower?

    Red campion usually blooms in late spring to early summer, providing a bright and very welcome splash of color in the garden during this time.

       

      Direct Sowing Outdoors (the easiest method and our preferred method):

      • Timing: We find we get the best results from sowing the Red Campion seeds directly in the garden in early spring or late summer and autumn.
      • Preparation: Prepare the soil by removing weeds and loosening it.
      • Sowing: Scatter the seeds on the soil surface and lightly press them into the soil.
      • Watering: Keep the soil moist until the seeds germinate.

      Sowing Seeds Indoors (Optional):

      • Timing: Start seeds indoors in the spring 6-8 weeks before the last expected frost date in your area. 
      • Containers: Use seed trays or small pots filled with a seed-starting mix.
      • Sowing: Sprinkle the seeds on the surface of the soil and lightly press them down, but do not cover them with soil, as rose campion seeds need light to germinate.
      • Watering: Moisten the soil gently with a spray bottle to avoid disturbing the seeds.
      • Light: Place the trays in a location with bright, indirect light or under grow lights.
      • Temperature: Maintain a temperature of around 65-70°F (18-21°C)

      Once the seedlings have developed a couple of sets of true leaves and the danger of frost has passed, harden them off by gradually exposing them to outdoor conditions over a week.

      How long do Red Campion seeds take to germinate?

      Seeds should germinate in 10-21 days. Keep the soil consistently moist during this period but not waterlogged.

      Transplanting seedlings:

      Once the seedlings have developed a couple of sets of true leaves you can move the seedlings around the garden, spacing them about 12-18 inches apart in well-drained soil and a sunny or partially shaded location.
