About Zinnia
Zinnias produce vibrant, daisy-like flowers in nearly every color except blue. These heat-loving annuals bloom prolifically from summer until frost and make excellent cut flowers. Available in heights from 6 inches to 4 feet, they're perfect for borders, beds, and containers.
General Care Instructions
Sunlight Requirements
Full sun (6-8 hours minimum) for best flowering. Can tolerate partial shade but may produce fewer blooms.
Watering Needs
Water when the top inch of soil is dry. Established plants are moderately drought-tolerant but bloom best with regular watering.
Temperature Range
Tolerates a wide temperature range from 60-90°F (15-32°C). Protect from frost.
Fertilizer Requirements
Apply balanced fertilizer every 4-6 weeks during the growing season. Avoid high-nitrogen fertilizers which promote foliage over flowers.
Harvesting
Flowers can be harvested when blooms are fully open, typically 60 days from planting. Cut stems at a 45-degree angle in the morning when flowers are hydrated. Remove spent blooms to encourage more flowering.
