Instructions Chevron Down Chevron Forward
    Growing Instructions:

    Sweet William seeds can be sown directly into the garden when the soil is warm and all danger of frost is passed. Soil temperature (not air temperature) should be warmer than 21°C (70°F) for seeds to germinate. Planting at a lower temperature will delay germination. Choose a location that receives at least 6 hours of sunlight daily. Space seeds and plant to the depth indicated below. Press seeds into the soil to ensure good contact and cover with 3 mm (1/8") of soil. After planting, water the seeds with a gentle mist or shower. A hard spray can wash soil away, dislodge seeds and clump them together. It is critical to keep the soil consistently moist, but not soggy during germination. Do not let the soil dry out, as young plants have underdeveloped roots and can quickly dehydrate, particularly in windy conditions. When your seedlings reach a height of a few centimetres (inches) and have developed 2 or 3 pairs of leaves, it is important to thin them out, according to the plant spacing indicated below to provide good air circulation and room to grow.

    For earlier blooms, seeds can be started indoors 6-8 weeks before the last frost in your area. Follow the seed depth and spacing guidelines indicated below. Once all danger of frost has passed, seedlings should be hardened off before planting in their growing location. Seedlings should be transplanted according to the plant spacing directions below. Regularly monitor your plants and ensure that the soil remains moist while they establish themselves in their new environment.

  • Planting Depth: 3 mm (1/8")

Suggestions Chevron Down Chevron Forward
Growing Suggestions:
  • While Sweet William is classed as a biennial, it often reseeds itself in optimum growing conditions and remain in the garden.
  • Regularly removing spent flowers, known as deadheading will extend flowering and to maintain plant vigor.
  • While they can tolerate some light shade, excessive shade can lead to leggy, weak plants. In hot regions, a little afternoon shade can help extend the blooming period.
  • During the growing season, water Sweet William regularly, but avoid overwatering as it promotes fungal diseases.
