Planting Depth and Spacing

Plant zinnia seeds or seedlings at the recommended depth, usually about ΒΌ inch, and space them according to the specific variety’s requirements for optimal growth.

Zinnia Care and Maintenance


Zinnias require full sun, so ensure they receive at least 6-8 hours of direct sunlight each day for vigorous flowering.


Keep the soil evenly moist but avoid overwatering, as excessive moisture can lead to fungal issues. Water at the base of the plants to prevent wetting the foliage.


Apply mulch to help retain soil moisture and suppress weed growth. Be cautious not to mulch too close to the base of the plants, which can encourage stem rot.


Regularly remove spent flowers to promote continuous blooming throughout the season.
