Plant the seed outside in the spring when temperatures remain above 50ºF. Sow into a shallow furrow 1/4" deep but do not cover, as seeds require light to germinate. Water evenly with a fine mist. Thin to 10-12" apart when 4" tall.
Transplanting: 4-6 weeks before last frost in 4" containers and keep soil warm and evenly moist. When seeds are 4" tall, move pots outside for a week to harden off then garden and plant on final spacing.
