To start seeds indoors: Sow seeds of upright cultivars 6 to 8 weeks before the last frost date; start dwarf cultivars about 4 weeks before the last frost date. Scatter seeds on the surface of the medium, but don’t cover them—they need light to germinate. Keep the soil temperature at 70° to 75°F; sprouts should appear in 10 to 20 days. Transplant the seedlings outdoors after the last frost.
