Hibiscus Sowing Instructions
Planting Depth:1/4”
Seed Spacing:12”-15”
Plant Spacing:24”-30”
Days to Germination:15-30 days
Germination Temperature:65°-75°F
Hibiscus mosheutus. Hibiscus can be direct-sown outdoors in warm areas or started indoors 8 to 10 weeks before transplanting outside after the threat of frost has passed. Soak seeds in water: once they sink, they are ready to plant. Sow seeds in good seed-starting medium at 70°F with even moisture, strong light and good ventilation. For consistent moisture during germination, cover the flats or pots with plastic wrap until seedlings emerge: then discard plastic. Harden off the seedlings by gradually acclimating them to outside conditions for 1 to 2 weeks before transplanting outside. Hibiscus are moisture-loving plants. Mulch to conserve moisture, water consistently and fertilize as necessary. Intolerant of night chills, bring potted plants indoors before a hint of fall frost. Summer flowering. Height: 24" to 36".
