Frequently Asked Questions
Are they difficult to grow from seed?
Not at all. Zinnias are one of the most rewarding flowers to direct-sow once the soil has warmed. They germinate quickly and thrive in the summer heat with minimal fuss.
Do I really need to cut them?
Yes! Regularly cutting your Zinnias is the "secret" to a productive season. Harvesting the flowers stimulates the plant to produce more side shoots, resulting in bushier plants and a massive increase in total bloom count.
Why do my leaves sometimes get spots?
Zinnias can be prone to powdery mildew, especially in humid conditions. To help, ensure adequate spacing for airflow, water at the base of the plant (avoiding the leaves), and choose sturdy, disease-resistant heirloom strains.
