Caring for Common Zinnia

Seedlings, like a majority of plants, require more frequent watering than mature ones. Watering young plants with an inch of water will result in healthy roots, which will help your plant flourish. Zinnias require less water later in their life cycle as they develop and are considered drought tolerant.

Pruning Zinnia

Zinnias should be pruned by cutting all the way down to the nearest branch. Pruning your zinnias will increase production and promote thicker growth, resulting in a lovely crop of blooms throughout the growing season.

Other
