Water: Manna ash thrives in a Mediterranean-like environment with dry summers and moist winters, preferring moderate humidity. Once established, it showcases good drought tolerance and should be watered biweekly. Its adaptability to various soil types allows resilience during rainy seasons, ensuring a stable growth cycle.

Fertilize: To keep manna ash healthy, fertilize with balanced nutrition every 3-4 weeks during the growing season. Use slow-release formulas sparingly in colder months and avoid over-fertilization. For young manna ash, reduce frequency, ensuring nutrients are accessible near the root zone through regular monitoring.

Pruning: Manna ash features attractive flowers and a broad canopy. Prune in early spring, removing deadwood and weak branches to boost structure and air circulation. Light pruning maintains health and aesthetics, while avoiding heavy pruning minimizes stress and pathogen spread.

Propagation: Manna ash is a deciduous tree valued for its ornamental and medicinal properties. Propagation is done via seeds, requiring cold stratification before sowing in well-drained soil with consistent moisture. Cloning through softwood cuttings is also possible for uniformity. Protect saplings until transplanting.
