Care
Light exposure
Position your Osteospermum moniliferum in full sun to achieve generous blooms and a compact shape. A minimum of 6 hours of direct sunlight is recommended. In shade, flowering becomes sparse and the plant becomes leggy.
Watering
Water regularly during growth and flowering, keeping the soil moist but well-drained. Reduce watering in summer if the plant goes dormant, and in winter depending on conditions. Avoid excess moisture which promotes rot.
Soil
Prefer light, fertile and well-drained substrate, such as potting soil mixed with sand or perlite. Slightly acidic to neutral pH works well. Ensure perfect drainage to prevent water stagnation.
Fertilization
Apply a balanced or slightly potassium-rich fertilizer every 15 to 20 days in spring and autumn during flowering. Reduce or stop fertilizing in summer and winter. Excess nitrogen promotes foliage at the expense of flowers.
Pruning and maintenance
Pinch young plants to encourage bushy branching. Regularly remove faded flowers to stimulate the formation of new buds. In late winter, prune lightly to rejuvenate the plant and remove dead wood.
Diseases and pests
Watch for powdery mildew in case of stagnant humidity: improve ventilation and reduce watering. Spider mites and whiteflies can appear indoors or in greenhouses; apply appropriate treatment at the first signs. Root rot is linked to excess water.
Did you know?
Osteospermum moniliferum originates from semi-arid regions of South Africa and derives its scientific name from the Greek 'osteon' (bone) and 'sperma' (seed), as its fruits resemble small bones. In Europe, these African daisies became very popular as balcony and terrace flowers during the 20th century, particularly appreciated for their ability to bloom during the quiet periods of the horticultural year.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
