How to Start Growing Zinnias

1. Choose the Right Location

Zinnias love the sun. Select a spot with full sunlight (at least 6–8 hours a day). More sun means more blooms.

2. Prepare the Soil

Zinnias aren’t fussy, but they thrive in:

Well-draining soil

Moderately fertile conditions

A soil pH between 5.5 and 7.5

Tip: Enrich the soil with compost before planting to encourage healthy growth.

3. Planting Zinnia Seeds

You can start zinnias in two ways:

Direct Sowing Outdoors: Once the soil warms to about 60°F (15°C), plant seeds ¼ inch deep and 6–12 inches apart.

Starting Indoors: Begin seeds 4–6 weeks before the last frost, then transplant them outside once it’s warm.

Good to know: Zinnias don’t transplant well if their roots are disturbed. Use biodegradable pots if starting indoors.

4. Watering and Care

Water at the base to avoid wetting leaves, which can lead to mildew.

Keep soil moist but not soggy.

Water deeply 1–2 times per week, depending on the weather.

5. Encourage More Blooms

Deadheads spent flowers to promote continuous flowering.

Pinch young plants at 8–12 inches tall to encourage bushier growth.
