Start seeds inside 3/15-4/15. Seeds need light to germinate - sow them on top of the soil and cover with a dome and place in indirect light. Place container on a heating mat for best results (70-80°). Water using a mist sprayer or using bottom watering method. Be sure to air out the dome for 15 min each day to prevent fungal growth. Days to seed germination: 10-20 days. When plants are 3" tall, transplant them outside or into a bigger container. Space plants 12-18" apart. Alternatively, you can sow seeds outside late May to early June. Sow 3-4 seeds every 12-18". Thin plants to the strongest seedling.
Clip leaves or clip stems and remove leaves. Use them fresh or dried.
Clip dried flower spikes when seeds are dark in color. Dry the on screens and flair, rub or thresh to remove the seeds.
