Calluna vulgaris - Scotch Heather

CALLUNA VULGARIS (Scotch Heather)

Calluna vulgaris, commonly known as Heather, is a low-growing, evergreen shrub that produces small, colorful flowers and thrives in acidic soils. Growing heather from seed requires patience, as germination can be slow and irregular.

1. Seed Preparation

  • Mix seeds with moist sand and refrigerate at 2–4°C (35–40°F) for 4–6 weeks to simulate natural winter conditions.

2. When to Sow

  • Best time: Early spring or autumn.

  • Can be sown indoors or in a cold frame for better control over germination conditions.

3. Soil & Location

  • Prefers well-draining, acidic soil with a pH of 4.5–5.5.

  • Use a mix of peat moss, sand, and perlite for optimal drainage.

  • Choose a full sun to partial shade location.

4. Sowing Depth & Spacing

  • Do not cover the seeds with soil, as they require light to germinate.

  • Gently press seeds onto the surface of moist soil.

  • Space seedlings 15–30 cm (6–12 inches) apart when transplanting.

5. Watering & Care

  • Keep the soil consistently moist but not waterlogged.

  • Use a fine mist sprayer to avoid disturbing the tiny seeds.

  • Germination can take 4–6 weeks or longer, so be patient.

6. Growth & Maintenance

  • Once seedlings are strong enough, harden them off before planting outdoors.

  • Mulch with pine needles or peat moss to maintain soil acidity.

  • Avoid excessive fertilization—use a light application of an acid-loving plant fertilizer in early spring.

Heather plants take time to establish but reward you with year-round foliage and seasonal blooms that attract pollinators. ??✨
