How to grow White Four O'Clocks seeds

Choose Your Planting Method

• Indoors: Start indoors 4-6 weeks before the last frost.
• Outdoors: Direct sow after all danger of 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 overnight in water before sowing; scarifying with a light nick or sandpaper helps too.
• Sow about 1/4 inch deep and press down firmly so the mix covers the seed.

Provide the Right Conditions

• Light: At least 6 hours of sun per day for seedlings.
• Temperature: 65-75°F (18-24°C).

Germination

• Seedlings emerge in 7-14 days in warm, moist soil.
• Keep the soil evenly moist; do not let it dry out completely.

Transplanting

• Move out after the last frost; harden off for about a week first.
• Space plants 12-18 inches apart in fertile, well-drained soil.

Care Tips

• Sun: Full sun is ideal; plants tolerate part shade but grow lankier.
• Water: Keep soil moist but not waterlogged; established plants tolerate dry spells.
• Fertilizer: Feed with a balanced fertilizer every 4-6 weeks during the growing season.
• Deadhead to limit self-seeding — four o’clocks reseed readily and can spread. Plants are tender perennials in mild climates, grown as annuals elsewhere; after frost, tubers can be dug and stored for spring.

Bloom Time:

Summer through fall; fragrant trumpet blooms open in the late afternoon and close by morning.
