Seed Treatment
Soak seeds in room-temperature water for 2–4 hours before planting.
Lightly press soaked seeds into moist, well-draining soil—do not cover, as light aids germination.
Germination Time
Optimal: 8–14 days
Maximum sub-optimal: 21 days
Optimum Temperature
Maintain between 18–21°C (64–70°F) for best germination results.
Sowing Method
Sow directly outdoors after the last frost, or indoors 4–6 weeks before last frost. If starting indoors, use biodegradable pots—Gypsophila dislikes root disturbance during transplanting.
When to Plant
Spring to early summer. Prefers full sun and performs best in cool, dry climates.
Soil Requirements
Choose light, well-draining soil with low to moderate fertility. Avoid overly rich soil to prevent excessive leafy growth and fewer blooms.
Watering
Keep soil evenly moist during germination. Once seedlings are established, reduce watering—Gypsophila is drought-tolerant and susceptible to overwatering.
Post-Germination Care
Thin seedlings to 15–20 cm (6–8") apart. Ensure good air circulation and full sun. No fertilization is necessary. Stake taller varieties if needed.
Bloom Time
Expect flowers 6–8 weeks after sowing, continuing through summer. Ideal for fresh or dried floral arrangements.
Maintenance
Deadhead regularly to encourage more blooms. Allow some flowers to go to seed if self-seeding is desired.
