How to Grow
It is recommended to start these seeds indoors before transplanting outdoors. To do so, first soak the seeds in water overnight to prep them. Then sow into peat pots at a depth of 1/4 to 1/2 inch. Sow 6-8 weeks before the last expected frost. Sow 2-3 seeds per plant, and keep them moist but not wet until germination. Under proper conditions, germination will occur in 2-4 weeks. Once seedlings are established, they can be transplanted directly outdoors if temperatures are staying above 45F degrees. Plant in rich, well-draining soil and water regularly.
