Distribution of Alluaudia

Distribution Map

Alluaudia is native to the semi-arid spiny forests of southwestern Madagascar, a major region known for its unique flora and fauna. It has adapted to the harsh, dry climate of this area, which constitutes its natural range. Over time, alluaudia has been introduced to other arid and semi-arid regions across various continents for xerophytic landscaping, often thriving in places with climates similar to its native habitat.

Water: Adapted to Madagascar's arid climate, alluaudia thrives on minimal watering and low humidity, storing water efficiently due to its succulent nature. Water weekly and monitor water availability during the growing season to prevent overwatering and ensure proper growth in xeriscapes.

Fertilize: For optimal growth, alluaudia requires bi-monthly applications of half-strength high-nitrogen fertilizers during its growing season. Avoid fertilizing in dormancy to prevent overfeeding. Monitor soil moisture for effective nutrient uptake and introduce fertilizers gradually to young plants, while preventing direct contact with alluaudia.

Pruning: Alluaudia is a succulent with vertical growth and thorny branches. Prune in early spring to enhance health, shape, and foliage density. Wear gloves for protection, and proper pruning improves air circulation, minimizing pest and disease risks.

Propagation: Alluaudia is propagated via cuttings from healthy, mature stems. Allow cut surfaces to callous before planting in well-draining soil and apply rooting hormone. Maintain appropriate moisture and provide indirect sunlight, while regularly checking soil dryness to avoid overwatering, which can affect rooting success.

Repotting: Alluaudia, a spiny succulent, requires repotting every 2-3 years in spring to support its growth. Use a pot 20% larger for root expansion and ensure drainage. After repotting, keep alluaudia in bright, indirect light and resume watering after a week to prevent root rot.
