Planting, Spacing & Care

Planting Tips: Ensuring a Strong Start

Site Selection: Full sun to partial shade with well-drained soil.

Digging the Hole: Twice as wide as the root ball but no deeper.

Planting: Position the shrub so the top of the root ball is at ground level. Backfill with native soil and water thoroughly.

Mulching: Apply a 5–7 cm layer of mulch around the base to retain moisture and suppress weeds. Keep mulch away from the trunk.

Watering: Deep watering during the first year to establish strong roots.

Hedging & Screening: Plant 1 m apart for a soft, textured hedge.

Feature Tree: 1.5 m – 2 m apart to let the form spread.

Avenue Planting Trees: Not typically used.

Caring for Your Tree

Watering: Regular watering for young plants; mature shrubs are drought-tolerant but benefit from occasional watering during extended dry periods.

Fertilizing: Generally does not require heavy fertilization; a balanced, slow-release fertilizer in early spring can encourage healthy growth.

Pruning: Minimal pruning is needed; can be trimmed to maintain shape or size as desired.

Pest & Disease Monitoring: Generally resistant to pests and diseases; ensure proper air circulation to prevent potential issues.

Enhancing Soil for Durable and Wind-Resistant Growth

Ideal Drainage: Prefers well-drained, sandy soils.

Well-Draining Soil: Perfect for Casuarina, promoting healthy root development and wind resistance.

If you have the following soil, here are some tips for you:

Sandy Soil: Naturally ideal; maintain nutrient levels with regular applications of slow-release fertilizers.
Clay Soil: Not typically suitable; heavily amend with gypsum, sand, and compost for better drainage.
Loamy Soil: Ensure it is well-draining; amend with organic materials to keep it aerated and conducive for growth.
Peaty Soil: Mix in sand for improved drainage; Casuarinas need well-aerated soil to thrive.
