Care
Light Exposure
Waltheria indica prefers a sunny or lightly dappled position to flower abundantly. Place it in direct sunlight for at least 6 hours per day. Direct exposure stimulates flowering and strengthens the plant.
Watering
Water regularly during the growing season to keep the soil moist but well-drained. Reduce watering in winter or during dry periods. Avoid waterlogging which promotes root rot.
Soil
Choose a light, well-drained substrate rich in organic matter. A mixture of potting soil and sand works perfectly. Good drainage is essential to prevent disease.
Pruning and Maintenance
Pinch the tips of young stems to encourage branching and a compact shape. Regularly remove spent flowers to extend the flowering period. Prune lightly after winter to maintain shape.
Fertilizing
Apply a balanced, diluted fertilizer every 15 to 20 days during the growing season (spring-summer). Reduce fertilization in autumn-winter. Excess nitrogen promotes foliage at the expense of flowering.
Diseases and Pests
Watch for scale insects and spider mites, particularly in dry environments. Powdery mildew can appear with excessive humidity and poor air circulation. Good drainage and regular aeration prevent most problems.
Did you know?
Waltheria indica has been used for centuries in traditional medicine in several tropical regions for its soothing properties. Its old name 'chéira' in India reflects its historical importance in Ayurvedic gardens. This humble plant with its small yellow flowers deserves far more recognition in contemporary gardens.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
