Dianthus barbatus, 'Sooty'

Germination

Sow directly in spring after danger of frost has passed. Surface sow seeds very thinly into prepared soil which has been raked to a fine tilth. Water well and keep moist until germination, 14-21 days at 12-15°C. Thin to 15cm when large enough to handle. Replant thinnings elsewhere. Can be started early indoors or under glass Jan-Mar and moved outside once danger of frost has passed. Can be sown under glass in May-July for flowering the following year.

Growing

Prefers rich, light , well-drained soil with full sun. Does not tolerate a wet soil in winter.

Cultivation

Deadhead to extend flowering and to maintain plant vigour. After the first killing frost cut all stems back to 2-4 cm above soil line. Has a short life expectancy of 3-4 years so propagate by division or cuttings to maintain the plants in your garden. Divide in spring as new growth appears.
