Instructions Chevron Down Chevron Forward
    Growing Instructions:

    Candytuft 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 1.5 mm (1/16") 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.

  • Planting Depth: 1.5 mm (1/16")
  • Seed Spacing: 2.5 cm (1")

  • Plant Spread: 40 cm (16")
Suggestions Chevron Down Chevron Forward
Growing Suggestions:
  • Candytuft prefers to grow in gravelly soil that is well-draining. It does not grow well in high humidity as the flowers tend to wilt and fungal diseases are more likely.
  • Young plants may not bloom their first year, because perennial candytuft needs 8 to 10 weeks of cold winter weather to initiate flower buds.
  • To keep candytuft looking tidy, prune away the top one-third of the foliage after blooming—this will keep the plant from getting leggy. Without this annual pruning, the plant can become rather scraggly in the border garden.
  • Candytuft cannot be divided as it has a thin and central main root.
