SF Terraced Garden Transformation Guide
Transform a sloped San Francisco garden into a terraced oasis, combining modern decking with naturalistic terraced landscaping. This guide details our approach to creating a multi-level garden that maximizes space while maintaining the tropical feel of the existing garden.
Starting point: Existing brick patio with established palms and tropical plants
Location Context
- Climate Zone: 10b (San Francisco)
- Typical Conditions: Mild temperatures, fog, occasional rain
- Challenges: Slopes, drainage requirements, microclimate considerations
- Key Feature: Views of surrounding hillside
Project Components
1. Base Decking Installation ($1,300)
The foundation of our renovation uses InstaDeck composite decking for the main seating area.
Materials Breakdown:
- InstaDeck Panels (4 sets of 4x4ft): $1,000
- Why InstaDeck? Low maintenance, long-lasting, modern aesthetic
- Installation tip: Ensure proper support and leveling
- Installation Materials: $300
- Includes gravel base, sand, landscape fabric
- Pro tip: Don't skip the proper base preparation
2. Terraced Garden Beds ($1,600)
Design Philosophy:
- 10" height differences between levels
- Natural flow from deck outward
- Creates distinct planting zones
- Improves drainage management
Materials & Methods:
Terrace Construction Layers (bottom to top):
1. Compacted base
2. Drainage rock + perforated pipe
3. Filter fabric
4. Retaining blocks
5. Soil
6. Plants
Key Components:
- Retaining Wall Blocks: $800
- Why blocks vs. wood? Longer lasting, better moisture resistance
- Installation tip: Stagger blocks for stability
- Drainage System: $300
- Critical for SF's rainy season
- Design prevents water accumulation
- Soil & Amendments: $500
- Custom mix for each level
- Focuses on drainage and root support
3. Plant Zones ($1,000)
Upper Terrace ($400)
- Full Sun Plants
- Bird of Paradise
- Drought-tolerant grasses
- Succulents
- Why these plants? Maximize sun exposure, drought resistant
Middle Terrace ($300)
- Mixed Sun/Shade
- Princess Flower
- Kangaroo Paw
- Native ferns
- Design principle: Create transition zone
Lower Terrace ($300)
- Shade Tolerant
- Sword Ferns
- Heuchera
- Japanese Forest Grass
- Focus: Ground coverage and texture

Budget Summary
Total Project Cost: $5,000
Cost-Saving Strategies
1. Material Sourcing Tips
- Buy materials like soil, mulch, and gravel in bulk to reduce costs (Bargain Landscape Supply)
- Look for recycled or reclaimed materials for hardscaping elements (Growtivation)
- Take advantage of end-of-season sales at nurseries and garden centers (Arka Energy)
- Check platforms like Craigslist or Facebook Marketplace for secondhand tools and materials
2. DIY Opportunities
- Prepare your own soil mix using compost and amendments
- Propagate plants from cuttings or seeds to expand your garden (Growtivation)
- Install your own gravel paths or simple retaining walls
- Install a basic drip irrigation system yourself
3. Phasing Suggestions
Learn more about phased landscape projects:
- Start with a single terrace or section of the garden
- Focus on drainage and soil improvement first
- Add plants over time, starting with key structural elements
- Plan for future expansion in your initial layout
4. Plant Propagation Methods
- Division: Split perennials like ferns and grasses
- Cuttings: Propagate succulents and shrubs
- Layering: Use for vines and shrubs
- Seed Saving: Collect and store seeds for future planting
