Carissa Macrocarpa ‘Desert Star’

• Native to South Africa, this versatile shrub adapts well to Australian coastal and inland conditions. It thrives in Mediterranean climates similar to many Australian regions.
• Produces sweetly fragrant white flowers throughout warmer months followed by bright red edible berries. The berries can be eaten fresh or used in jams.
• Dense thorny growth makes it excellent for security hedging and wildlife habitat. Birds love the berries while the thorns provide safe nesting sites.
• Extremely drought tolerant once established, requiring minimal water and maintenance. Perfect for water-wise Australian gardens.

• Water weekly during establishment, then monthly in summer and rarely in winter once mature. Check soil moisture 5cm deep before watering.
• Position in full sun to light shade with protection from strong winds. Coastal positions are ideal due to salt tolerance.
• Plant in well-draining soil enriched with compost or aged manure. Avoid heavy clay without drainage improvement.
• Feed monthly with liquid fertiliser during growing season or apply slow-release granules in spring. Avoid high-phosphorus fertilisers.
• Prune lightly after flowering to maintain shape and size. Wear gloves due to sharp thorns.
• Mulch around base to retain moisture and suppress weeds, keeping mulch away from trunk.

• Provide full sun to partial shade for best flowering and fruiting performance. Morning sun with afternoon protection works well in hot climates.
• Water deeply but infrequently once established, allowing soil to dry between waterings. Reduce watering significantly in winter months.
• Plant in well-draining soil with good organic content. Sandy loam or clay loam soils work best.
• Prune after flowering to maintain shape and encourage bushier growth. Regular light pruning promotes more flowers.
• Fertilise in spring with slow-release native plant fertiliser or compost.

• Scale insects can attach to stems and leaves, causing yellowing and stunted growth. Treat with horticultural oil or insecticidal soap.
• Root rot develops in waterlogged soils with poor drainage. Ensure well-draining soil and reduce watering frequency.
• Aphids may cluster on new growth tips, causing leaf curling. Spray off with water or use beneficial insects like ladybirds.
• Fungal leaf spot appears as brown patches during humid conditions. Improve air circulation and avoid overhead watering.
