Zinnia

60d to harvest

Radiant coral blooms open like small lanterns, their warm salmon-orange petals glowing against crisp green foliage. Magellan Coral forms sturdy, well-branched plants that produce abundant, fully double flowers with a plush, velvety texture—ideal for fresh bouquets and long-lasting cut arrangements. Grow it for a season-long splash of color in beds and borders, then harvest stems at peak bloom for display-worthy impact.

Frequently Asked Questions

What’s a common pest or disease issue for Zinnia elegans (Magellan Coral), and how do I fix it?

Powdery mildew often shows up on Zinnia elegans as a white, dusty coating on leaves, usually when plants are crowded and airflow is poor. Remove badly affected leaves, water at the soil line (not the foliage), and space plants so leaves don’t touch. If it’s spreading, spray a labeled powdery mildew fungicide according to the product directions and keep the foliage dry whenever possible.

How often should I water Magellan Coral zinnia during the main growing phase?

During active growth and flowering (roughly after plants establish until mid-season), water deeply about 1–2 times per week, aiming for consistently moist but not soggy soil. Let the top 1 inch of soil dry slightly between waterings, since Zinnia elegans develops problems when kept wet. In hot, windy weather you may need more frequent deep watering, but always avoid daily light sprinkling.

How can I tell when Magellan Coral zinnia is ready to harvest?

Harvest when the flower heads are fully colored and the petals are fresh and open, typically around 60 days from sowing/starting. Use a pair of clean snips and cut stems when the central florets are set and the blooms look at their peak, not when they’re wilting or mostly dried out. For best vase life and continued flowering, harvest in the morning after dew dries and before afternoon heat.
