For an early start, start seeds indoors 2-3 weeks before the last frost in peat pots or Jiffy 7s at 70F. Harden off seedlings before transplanting outdoors after all danger of frost. Water regularly and fertilize twice during the season with a 15-5-15 granular fertilizer or equivalent. Germination takes 5-10 days.
