Care
Sunlight
Place your Mexican ambrosia in full sun for optimal growth. It tolerates partial shade but prefers well-lit and warm locations. Avoid overly shaded areas that would slow its development.
Watering
Water regularly while keeping the soil moist but well-drained, especially during growth. Reduce watering in autumn. Let the soil surface dry slightly between waterings to prevent root rot.
Soil
Prefer light, well-drained soil rich in organic matter. Universal potting soil lightened with sand or perlite works perfectly. Avoid heavy and compact soils that retain too much moisture.
Fertilizer
Apply balanced fertilizer diluted every 15 to 20 days during active growth periods (spring-summer). Moderate feeding is sufficient; don't overdo it, this plant isn't demanding.
Pruning and Maintenance
Pinch young stems to encourage a compact, branched form. Remove faded flowers to extend blooming. In autumn, eliminate dry or damaged stems.
Diseases and Pests
Watch for spider mites in dry conditions. Powdery mildew may appear if humidity stagnates. Ensure good air circulation and avoid excess foliage moisture. Infestations generally remain minor in standard cultivation.
