Zinnia

How to care for zinnia

• Light: Requires full sun, at least 6-8 hours of direct sunlight daily, for abundant flowering. Less sun leads to fewer blooms and leggy growth.
• Water: Water deeply and regularly, especially during dry spells, to keep the soil consistently moist. Avoid overhead watering to prevent mildew.
• Soil: Prefers well-draining, fertile soil rich in organic matter. They are not particular about soil pH but avoid heavy, poorly draining clay.
• Temperature: Thrives in warm temperatures, typically above 60°F (15°C). They are sensitive to frost and should be planted after the last frost date.
• Humidity: Average outdoor humidity is suitable. Good air circulation helps prevent fungal diseases.
• Fertilizer: Amend soil with compost at planting; a balanced granular fertilizer can be applied once a month for continuous blooms. Avoid excessive nitrogen.
• Propagation: Easily propagated from seeds directly sown outdoors after the last frost. They germinate quickly and grow rapidly.
