Timing:
Start indoors 6-8 weeks before last frost date. Or direct sow outdoors after the last frost date, every two weeks into July for a continuous bloom period. Seeds should germinate in 10-20 days. Ideal soil temperature for germination: 21-30°C (70-85°F).
Starting:
If starting indoors, use peat or coir pots and bottom heat. Only cover seed by a couple of millimetres (1/8″) of soil. Transplant out after last frost at 15-30cm (6-12″) apart.
Growing:
Ideal pH: 6.0-7.0. Iberis does not respond well to transplanting or being moved. Direct sowing is probably simplest. Choose any well-drained garden soil with a neutral pH. Trim plants lightly after flowering to encourage a second bloom. Iberis may self sow.
