What is an African Daisy?
African daisy, belonging to the genus Osteospermum, is a group of flowering plants known for their daisy-like appearance and tolerance of various growing conditions. These perennials, often grown as annuals in cooler climates, feature spoon-shaped petals and a central disc, resembling traditional daisies but with a wider colour palette and longer blooming period.
How to Grow African Daisy
Planting African Daisy
- Choosing a Location: African daisies thrive in full sun and well-drained soil. Select a site that receives at least 6-8 hours of sunlight daily to encourage maximum flowering.
- Soil Preparation: These flowers prefer slightly acidic to neutral soil (pH 6.0-7.5). Amend heavy clay or sandy soil with compost or well-rotted manure to improve drainage and fertility.
- Planting: For cooler regions, start seeds indoors 6-8 weeks before the last frost date. In warmer climates, sow seeds directly into the garden or plant nursery-grown seedlings after the danger of frost has passed. Space plants about 12-18 inches apart to allow for air circulation and growth.
Care and Maintenance
- Watering: Keep the soil consistently moist, especially during hot, dry periods. However, avoid overwatering to prevent root rot.
- Feeding: Apply a balanced, slow-release fertilizer at planting time, followed by a liquid fertilizer every 4-6 weeks during the growing season to support continuous blooming.
- Deadheading and Pruning: Regularly remove spent flowers (deadheading) to encourage new blooms. Light pruning of leggy stems can also promote bushier growth.
Common Pests and Diseases
African daisies are relatively resistant to pests and diseases, but watch out for common issues like aphids and powdery mildew. Control aphids with insecticidal soap and manage fungal diseases by ensuring good air circulation and avoiding overhead watering.
