Here’s how to seed and grow it successfully:

🌸 When to Sow

Indoors (for earlier blooms):

• 4–6 weeks before the last frost

Outdoors (direct sowing):

• After last frost, when soil is warm (60°F / 16°C or above)

🌱 How to Sow

Soil & Location

• Use light, well-draining soil

• Choose a full-sun location (6–8+ hours of direct sunlight)

• Avoid rich soil (can cause more leaves, fewer flowers)

Sowing Depth

• Sow seeds ¼ inch (6 mm) deep

• Cover lightly with soil and gently firm

Spacing

• Thin or transplant seedlings to 9–12 inches apart for dwarf types

• Rows: space about 12–15 inches apart

🌡️ Germination Conditions

• Temperature: 70–75°F (21–24°C)

• Germination time: 5–10 days

🌿 After Germination

• Thin when seedlings are 2–3 inches tall

• If indoors, harden off for 5–7 days before transplanting

🌼 Bloom Time

• Blooms in 60–75 days from sowing

• Flowers mid-summer to frost

• Great for cut flowers, pollinators, and color in garden beds

🐝 Care Tips

• Deadhead spent blooms to encourage more flowering

• Water at soil level to prevent mildew

• Zinnias prefer dryer conditions once established

• Do not over-fertilize (promotes leafy growth, fewer blooms)
