Easy to grow. In late May, choose a sunny site with well-draining soil and sow seed about 6-12 mm deep, and 7.5-10 cm apart. Thin or transplant seedlings to 30-45 cm apart. Seed can be started 2-3 weeks early indoors using plantable peat pots or Jiffy 7’s at 21° C. Harden off seedlings then, transplant to a site in full sun. Keep plants evenly watered and fertilize twice during the season with a granular 15-5-15 or equivalent. Germination occurs in 5-10 days.
