How to grow Rosie O'Day Alyssum seeds

Choose Your Planting Method

• Indoors: Sow 4-6 weeks before your last frost for the earliest bloom.
• Outdoors: Direct sow after the last frost, or sow in late summer in mild climates for fall bloom.

Prepare Your Materials

• Seed-starting trays or pots
• Well-draining seed-starting mix
• Spray bottle for misting

Sowing the Seeds

• Sow on the surface of the mix and press in lightly; the seeds need light to germinate, so cover only with a whisper of mix or vermiculite, or leave uncovered.
• Mist to settle the seeds into the surface.

Provide the Right Conditions

• Light: Light is required; do not bury the seeds deeply.
• Temperature: 64-70°F (18-21°C).

Germination

• Seeds germinate in 7-21 days.
• Thin or transplant seedlings to about 6 inches apart.

Transplanting

• Plant out after the last frost, spacing 6 inches apart.
• Plants are compact and shallow-rooted; handle gently.

Care Tips

• Sun: Full sun to light shade.
• Water: Keep the soil evenly moist, especially until established; soggy soil causes rot.
• Fertilizer: A light feeding at planting is enough; avoid heavy nitrogen.
• Shear plants back by half if bloom pauses in hot weather; they will flush back into flower within about four weeks as it cools.

Bloom Time:

Late spring to midsummer, and again in fall if sheared back.
