Growing Instructions

Climate & Position

Light
• Best grown in full sun to light partial shade.
• Good air circulation is beneficial.

Climate
• Prefers warm, light frost conditions.


Soil Requirements

Drainage
• Requires excellent drainage.
• Avoid heavy clay or waterlogged soils, which can cause plant failure.


Soil type

Ideal soils include:
• Sandy soils
• Sandy loam
• Light loam with organic matter

Soil pH
• Slightly acidic to neutral is preferred.
• Lime-free or low-alkalinity soil is ideal.

Soil fertility
• Excess nutrients, particularly phosphorus, can cause issues.



Water Requirements

Establishment phase
• Water regularly during the first year until plants are well established.
• Soil should remain lightly moist but never waterlogged.
• Allow soil to dry slightly between watering cycles to prevent root rot.

Mature plants
• Become drought tolerant once established.
• Occasional deep watering during prolonged dry periods is beneficial.



Fertiliser

Avoid:
• High-phosphorus fertilisers
• Excess feeding

Recommended approach:
• Use light applications of low-phosphorus fertiliser in late winter or early spring.
• Organic seaweed or low-analysis fertilisers are suitable.



Mulching
Mulching is beneficial for root health.

Recommended mulch:
• Pine bark
• Wood chips
• Organic mulch

Benefits:
• Retains moisture
• Suppresses weeds
• Keeps roots cool and stable.

Care & Maintenance

Pruning & Maintenance

Pruning
• Light pruning after flowering helps maintain compact shape and encourages branching.
• Remove dead or damaged stems.

Avoid:
• Hard pruning into old wood.


General maintenance
• Keep the root zone undisturbed where possible.
• Maintain good airflow around plants.
• Ensure good drainage and use free-draining mixes if growing in pots.


Common Growing Problems:
Poor drainage and overwatering (particularly problematic in heavy soils) are the most frequent cause of plant failure. Symptoms include sudden plant decline and root rot. Due to sensitivity, avoid using phosphorus.
