Sow ⅛ in deep at 80°F on a heat mat. Slow to sprout (14–21 days) — start early.
Sow ¼ in deep at 80°F; needs steady warmth for 8 weeks indoors.
Sow ¼ in deep in trays; keep tops trimmed to 3 in for stocky transplants. Choose day-length type for your latitude.
Soak seed overnight; slow to germinate (3 weeks). Surface-sow under lights.
Sow ¼–½ in deep. Germinates in 5–10 days.
Sow ¼ in; transplant into deep holes. Germinates in 10–14 days.
Sow ¼ in deep; set transplants at nursery depth. Germinates in 10–21 days at 65–75°f.
Sow ¼ in deep. Germinates in 7–14 days.
Sow Surface sow — needs light. Germinates in 7–14 days.
Sow ¼ in deep. Germinates in 14–21 days.
Sow ¼ in deep. Germinates in 10–21 days.
Sow Surface-sow to ⅛ in — seeds need some light to germinate. Germinates in 10–21 days at 65–70°f.
Sow Surface sow — needs light to germinate. Germinates in 10–14 days.
Sow Surface sow — needs light. Germinates in 7–21 days.
