About Benary's Giant Coral Zinnia

Zinnia elegans · also called Common Zinnia, Youth-and-Age · flowering

Benary's Giant Coral Zinnia is a tall, large-flowered dahlia-like zinnia series producing 12-14 cm wide salmon-coral blooms on strong stems from midsummer to frost. A top choice for cut-flower gardens, it is among the most productive and disease-resistant zinnia series available. Pet-safe and easy to grow from seed.

Ideal humidity: 40-60%

Watch for — Powdery mildew: White powdery coating appears on leaves, especially in humid conditions or with overhead watering. Space plants well, water at the base only, and choose mildew-resistant series like 'Benary's Giant'. Remove badly affected leaves promptly.

The watering schedule, season by season

Benary's Giant Coral Zinnia flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for benary's giant coral zinnia is water at the base every 5-7 days, allowing the top 3-5 cm of soil to dry between waterings; overhead watering should be avoided, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Zinnias prefer a moderate moisture regime — not drought-stressed but never waterlogged. Watering at the base and early in the morning is critical, as wet foliage triggers powdery mildew, the primary disease threat. Mature plants tolerate short dry periods well.
