As a landscape designer working in Perth for over 16 years, I’ve seen countless gardens transform from challenging sandy plots into thriving native sanctuaries.

Our sandy soils present both opportunities and challenges, and I’m excited to share what actually works based on real projects we’ve completed across Perth.

Understanding Perth’s Sandy Soil Profile

Before we dive into plant selections, let’s talk about what we’re working with.

Perth’s coastal plain consists predominantly of Bassendean and Spearwood sands – these are typically nutrient-poor and free-draining.

While this might sound problematic, many of our stunning native plants have specifically adapted to these conditions.

Best Native Trees for Perth’s Sandy Soils

From my experience installing gardens across Perth’s northern and southern suburbs, these native trees consistently perform well in our sandy conditions:

Small Trees (Under 5m)

• Coastal Wattle (Acacia cyclops)
• WA Peppermint (Agonis flexuosa ‘Nana’)
• Native Frangipani (Hymenosporum flavum)

Medium Trees (5-10m)

• WA Red Flowering Gum (Corymbia ficifolia)
• Rottnest Island Tea Tree (Melaleuca lanceolata)
• Coastal Sheoak (Casuarina equisetifolia)

One of our clients, Peter Harrison, mentioned in his review:

“Alex recently designed/landscaped my front and rear yards… we wanted to maintain a similar structure with a low maintenance outcome. Alex managed this exactly to our expectations.”

This kind of success comes from choosing the right plants for our local conditions.

Native Shrubs and Ground Covers

These plants form the backbone of any Perth native garden:

Medium Shrubs

• Coastal Rosemary (Westringia fruticosa)
• Blue Bush (Acacia saligna)
• Native Hibiscus (Alyogyne huegelii)

Low-Growing Plants

• Native Pigface (Carpobrotus virescens)
• Snake Bush (Hemiandra pungens)
• Native Violet (Viola hederacea)

Practical Tips for Planting in Sandy Soil

Through years of installing gardens across Perth, I’ve developed these proven techniques:

1. Soil Preparation
   • Add organic matter to the planting hole
   • Use water-storing crystals sparingly
   • Apply native plant fertiliser specifically designed for phosphorus-sensitive species
2. Planting Time
   • Plant during autumn or early winter
   • This gives plants time to establish before summer
   • Morning planting is preferable to afternoon
3. Initial Care
   • Water deeply but infrequently to encourage deep root growth
   • Apply mulch to retain moisture
   • Monitor for signs of stress during the first summer

One of our satisfied clients, Zoe Gibson, noted:

“It’s been almost two years and my garden is thriving! Would definitely use his services again.”

This success comes from proper initial establishment.

Common Challenges and Solutions

Challenge 1: Water Retention

In Perth’s sandy soils, water retention is a significant issue. We address this through:

• Strategic soil amendments
• Proper mulching techniques
• Efficient irrigation design

Challenge 2: Nutrient Deficiency

Sandy soils are naturally low in nutrients. We manage this by:

• Using slow-release native plant fertilisers
• Adding composted organic matter
• Regular soil monitoring

Challenge 3: Wind Exposure

Many Perth gardens face strong winds. Solutions include:

• Strategic placement of wind-breaking species
• Proper staking techniques
• Gradual hardening off of new plants

Design Considerations for Native Gardens

When designing native gardens in Perth’s sandy soils, I consider:

1. Layering Plants
   • Tall background plants for screening
   • Mid-height flowering species
   • Ground covers for soil stabilisation
2. Seasonal Interest
   • Spring-flowering species
   • Summer-resilient plants
   • Year-round foliage interest
3. Functionality
   • Privacy screening
   • Wind protection
   • Habitat creation

As noted by our client Phil:

“The level of professionalism Perth Landscapes offers is next to none. Considerably flexible to all my specific requirements. Most importantly offering further suggestions to add value, improve sustainability whilst considering future implications.”

Maintenance Requirements

Native gardens in sandy soils need specific maintenance:

Year 1

• Regular deep watering
• Weed management
• Light pruning as needed

Established Gardens

• Annual fertilising
• Periodic pruning
• Mulch replenishment

Long-term Care

• Monitor for pest issues
• Remove dead growth
• Adjust irrigation as needed

Getting Started with Your Native Garden

If you’re considering a native garden for your Perth property, here’s what to consider:

1. Site Assessment
   • Sun exposure
   • Wind patterns
   • Existing soil conditions
2. Plant Selection
   • Choose plants suited to your specific area
   • Consider mature sizes
   • Plan for succession planting
3. Professional Design
   • Ensure proper plant spacing
   • Create effective drainage patterns
   • Design efficient irrigation systems

Cost Considerations

Installing a native garden in sandy soil involves several elements:

1. Initial Costs
   • Soil improvement
   • Plants and materials
   • Installation labour
2. Long-term Investment
   • Reduced water usage
   • Lower maintenance needs
   • Increased property value
3. Professional Services
   • Design consultation
