🌱 How to Care for Casuarina to Prevent Dieback (Dead Wood)?

💧 How to Water

Water newly planted seedlings frequently until they show clear signs of growth (usually 6 to 12 months). Once established, the tree tolerates long periods of drought and only needs extra water during very prolonged dry spells; avoid waterlogging, as poorly drained soil promotes root rot.

☀️ Lighting

Needs direct full sun (minimum of 6 hours daily) to grow vigorously and maintain a dense canopy; in partial shade, it grows sparsely and more slowly, and does not tolerate dense shade.

🪴 Ideal Soil

Thrives best in sandy, light, and well-drained soils, but is extremely adaptable to poor, compacted, rocky, and saline soils, with a pH from slightly acidic to alkaline (5.5 to 8.5). The only factor it does not tolerate is prolonged waterlogging.
