🌱 Step-by-Step: How to Plant Zinnias from Seed
1. Choose the Right Spot
Zinnias love full sun (at least 6–8 hours daily).
Pick a location with well-drained soil to prevent root rot.
2. Prepare the Soil
Loosen the soil with a garden fork.
Add compost for nutrients and better drainage.
3. Plant the Seeds
Sow seeds directly into the garden after the last frost.
Space seeds about 6–12 inches apart, depending on variety.
Cover lightly with ¼ inch of soil.
4. Water Properly
Keep soil moist until seeds germinate (usually within 5–7 days).
After sprouting, water at the base to avoid wetting leaves, which can cause mildew.
5. Thin Seedlings
Once seedlings are 3–4 inches tall, thin them to give each plant room to grow.
💡 Easy Hacks You’ll Want to Save
Hack 1: Start Indoors for a Head Start

Remove faded flowers to keep the plant producing new ones all season.

At the end of the season, save dried flower heads to harvest seeds and replant for free.
