Alyssum - Rosie O'Day

1600 seeds

🗓️ When to Sow

• Indoors: Start 6–8 weeks before the last frost date.

• Outdoors: Direct sow as soon as soil can be worked in spring — Alyssum tolerates cool weather and light frost.

• Also great for autumn sowing in mild climates for early spring bloom.

🌱 How to Sow

✅ Indoors (for early blooms)

1. Prepare Containers

   • Use shallow seed trays with a fine, moist, well-draining seed-starting mix.

2. Sow Seeds

   • Alyssum seeds are tiny — surface sow and do not cover.

   • Press gently into the soil for good contact.

3. Moisture & Light

   • Mist lightly to keep the surface moist.

   • Cover with a clear lid or plastic until germination begins.

   • Provide bright light or grow lights.

4. Temperature

   • Keep at 18–21°C (65–70°F).

   • Germination occurs in 5–10 days.

✅ Direct Sowing Outdoors

1. Prepare the Site

   • Choose a spot in full sun to partial shade.

   • Lightly rake the surface and moisten it.

2. Sow the Seeds

   • Sprinkle seeds directly on the soil surface.

   • Press gently into the soil — do not cover.

3. Watering

   • Mist or gently water to keep the soil moist until germination.

🌿 After Germination

• Thin seedlings to 4–6 inches (10–15 cm) apart when large enough to handle.

• Alyssum will spread to form a low carpet of blooms.

🌼 Growing Notes

• Bloom Time: Early spring through summer (and into fall in cooler climates).

• Height: 4–6 inches (10–15 cm).

• Water: Moderate — prefers regular moisture but is somewhat drought-tolerant once established.

• Deadheading: Not essential, but trimming back can encourage reblooming.

• Soil: Well-draining, average fertility.

• Self-sows lightly in suitable conditions.
