Care
Light exposure
Install the fanpetals plant in full sun for optimal growth and generous flowering. It tolerates partial shade but will develop less vigorously. Protect it from strong winds that could damage it.
Watering
Keep the soil moist but well-drained during active growth, particularly during hot periods. Reduce watering in winter or in cooler climates. Avoid waterlogging which promotes rot.
Soil
Prefer fertile, well-drained soil that is slightly acidic to neutral. Rich potting soil enriched with organic matter promotes good growth. Ensure excellent drainage to avoid stagnant moisture.
Fertilizer
Apply a balanced fertilizer every 15 to 20 days during the growing season. Reduce applications in winter. Excess nitrogen promotes foliage at the expense of flowering.
Pruning and pinching
Pinch young stems to encourage branching and obtain a more compact and bushy plant. Remove faded flowers to extend flowering. Cut back the plant at the end of winter if it becomes sparse.
Diseases and pests
Watch for spider mites and whiteflies in dry, hot environments. Powdery mildew can appear in case of excessive humidity and poor air circulation. Healthy foliage and good hygiene limit problems.
Did you know?
The fanpetals, or Sida rhombifolia, gets its common name because its leaves have long been used to prepare a local herbal tea in tropical America, although it has no botanical connection to true tea (Camellia sinensis). This plant is part of the traditional pharmacopoeia of several cultures, and its hardiness in warm climates makes it popular in family gardens in tropical Africa and Asia.
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.
