How to grow Summer Storm Mallow Hibiscus seeds

Choose Your Planting Method

• Indoors: Start indoors 8–10 weeks before the last frost for the earliest blooms.
• Outdoors: Sow directly after the last frost, once the soil is warm.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Spray bottle for misting

Sowing the Seeds

• Soak seeds in room-temperature water for about 24 hours before sowing.
• Sow 1/4 inch deep.

Provide the Right Conditions

• Light: Full sun.
• Temperature: Around 70°F (21°C) for germination; warmth speeds sprouting.
• Humidity: Keep the soil consistently moist, never waterlogged.

Germination

• Seedlings often emerge within 1–2 weeks in warm soil; allow up to 2–3 weeks.
• Grow on in strong light so seedlings stay stocky.

Transplanting

• Set out after all frost danger has passed.
• Space plants 24–36 inches apart to allow for their bold mature size.

Care Tips

• Sun: Full sun for the most flowers.
• Water: Keep soil consistently moist; these mallows dislike drying out.
• Fertilizer: Feed lightly during the growing season.
• Remove spent flowers to keep plants tidy and encourage more buds.

Bloom Time:

Summer through early fall; plants started early indoors may begin blooming about 135–150 days from sowing.
