About Zinnia
Zinnia is one of the fastest and most rewarding warm-season annuals to grow from seed or transplant, producing an abundance of bright, long-lasting flowers in nearly every color except true blue, from late spring through the first fall frost, making it a favorite for cutting gardens as well as border color. Heights range from compact dwarf varieties under a foot tall to tall cutting-garden types reaching 3 feet, offering flexibility across different garden uses. Zinnias thrive in Georgia's full sun and heat and are fairly drought tolerant once established, needing regular water mainly during the establishment period. Good air circulation is important, since crowded plantings and overhead watering that wets the foliage can lead to powdery mildew in humid Southern summers; spacing plants properly and watering at the soil level rather than overhead significantly reduces this risk. Regular cutting or deadheading of spent blooms encourages continuous flower production throughout the season, and Zinnias are also a strong butterfly attractant, making them popular in pollinator-focused garden designs alongside their cut-flower value.

Planting Instructions & Regional Tips
Plant Zinnia in full sun after the last spring frost date; it grows quickly from direct-sown seed or transplants. Space plants properly for good air circulation to reduce powdery mildew risk in Georgia's humid summers, and water at soil level rather than overhead. Deadhead or cut flowers regularly to encourage continuous blooming through fall. Once established in a Gwinnett County landscape, it needs only occasional deep watering during dry stretches rather than a regular irrigation schedule.

Zinnia FAQs
How do I prevent powdery mildew on zinnias?
Prevent powdery mildew on Zinnia by spacing plants properly for good air circulation, watering at soil level rather than overhead to keep foliage dry, and choosing mildew-resistant varieties where available. Georgia's humid summers make zinnias particularly prone to this fungal issue when plantings are crowded.
Do deer eat Zinnia?
Yes, Zinnia is not considered deer resistant and can be browsed by deer, especially newly planted specimens. In Gwinnett County areas with heavy deer pressure, fencing or repellent application is worth considering until the plant is well established.
