Start seeds indoors 6, 8 weeks before your last spring frost date at soil temperatures of 65, 75°F. Lobelia seeds are very fine; surface-sow them on moist seed-starting mix without covering, as they need light to germinate. Keep soil moist and expect germination in 10, 15 days. Transplant seedlings into individual pots once they develop true leaves.
Harden off seedlings by gradually exposing them to outdoor conditions over 7, 10 days. Transplant outside only after all danger of frost has passed, as Palace Series is half-hardy and sensitive to cold. Space plants 6 inches apart, with 18 inches between rows. Transplant into full-sun locations with soil pH 6.0, 7.0.
Palace Series Lobelia's naturally compact, bushy growth habit requires minimal pruning. Pinch back seedlings when 2, 3 inches tall to encourage bushier, more branched plants. Deadhead spent flowers regularly throughout the season to promote continuous blooming.
