The Process Of Zinnia Reseeding

Zinnias, if allowed to flower and set seed, have a good chance of germinating and growing the following spring.

Zinnia Reseeding

Zinnias thrive in temperatures of 70ºF and above. They prefer full sun exposure and well-draining soil.

Zinnia Growth Requirements

Zinnias make great cut flowers! They will last in a vase for a week or more if harvested at the correct stage.

Harvesting Zinnias

If you want to allow zinnias to reseed, let the plant flower and set seed naturally. After the flowers have set seed, you can leave them alone or help the seeds drop onto the soil surface.


Zinnias are Summer annuals, meaning they typically grow best and flower during warm weather. They will not grow well if the temperature is below 60ºF.

Zinnia Season

Plant zinnias in full sun. Full sun exposure means that the plants will receive at least 6 to 8 hours of direct sunlight per day.

Zinnia Location

Zinnias are not picky about soil type, but they will grow best in a well-draining soil. Waterlogged soils that do not often dry out will be a problem because of disease concerns.
