Understanding Drought-Tolerant Landscaping
Drought-tolerant landscaping (also called xeriscaping) uses design strategies and plant selection to create beautiful gardens that require minimal supplemental water. In San Francisco's Mediterranean climate—with wet winters and dry summers—this approach works perfectly with nature's rhythms.
The 7 Principles of Water-Wise Landscaping
1. Smart Planning & Design
Create a landscape plan that groups plants by water needs (hydrozoning), minimizes turf areas, and uses hardscaping strategically.
Impact: Reduces water use by 30-50% through efficient design alone
2. Soil Improvement
Amend soil with compost (3-4 inches) to improve water retention. Healthy soil holds moisture longer and reduces watering frequency.
Impact: Soil with 5% organic matter holds 4x more water than unamended soil
3. Appropriate Plant Selection
Choose drought-adapted plants native to Mediterranean climates. California natives are ideal—they've evolved for our exact conditions.
Impact: Native plants use 80% less water than traditional lawns
4. Efficient Irrigation
Install drip irrigation or soaker hoses that deliver water directly to roots. Use smart controllers that adjust for weather.
Impact: Drip systems are 90% efficient vs. 50-70% for sprinklers
5. Mulching
Apply 3-4 inches of organic mulch around plants to reduce evaporation, moderate soil temperature, and suppress weeds.
Impact: Mulch reduces water evaporation by 70%
6. Minimize Turf Areas
Replace water-hungry lawns with native grasses, ground covers, or permeable hardscaping. Keep turf only where actively used.
Impact: Each 100 sq ft of lawn removed saves 6,000 gallons/year
7. Proper Maintenance
Deep, infrequent watering encourages deep roots. Adjust irrigation seasonally. Prune strategically to maintain plant health.
Impact: Deep watering reduces frequency by 50% while strengthening plants

Irrigation Strategies for Maximum Efficiency
Drip Irrigation: The Gold Standard
Drip irrigation delivers water slowly and directly to plant roots, minimizing evaporation and runoff. It's the most efficient irrigation method available.
Drip System Benefits
- ✓ 90% efficient (vs 50-70% for sprinklers)
- ✓ Reduces disease by keeping foliage dry
- ✓ Prevents weeds by watering only desired plants
- ✓ Flexible - easily adjusted for individual plant needs
- ✓ Works on slopes without runoff
- ✓ Saves time - fully automated
Smart Controllers Save Even More
Modern smart irrigation controllers use weather data, soil sensors, and evapotranspiration rates to automatically adjust watering schedules.

Design Strategies for Beautiful Water-Wise Landscapes
1. Create Hydrozones
Group plants with similar water needs together. This prevents overwatering drought-tolerant plants and underwatering thirstier species.
Sample Hydrozone Layout
- Zone 1 (High Water): Small lawn area for kids/pets, vegetable garden - 20% of landscape
- Zone 2 (Moderate Water): Flowering perennials, ornamental grasses - 30% of landscape
- Zone 3 (Low Water): Native shrubs, succulents, Mediterranean plants - 50% of landscape
2. Use Hardscaping Strategically
Incorporate patios, pathways, decks, and decorative rock to reduce planted areas while adding function and visual interest.
- Permeable pavers: Allow rainwater infiltration, reduce runoff
- Decomposed granite: Natural-looking, affordable, excellent drainage
- Flagstone paths: Beautiful, durable, can plant between stones
- Gravel mulch: Decorative, prevents evaporation, low maintenance
3. Embrace Sustainable Design Elements
Rain Gardens
Shallow depressions that capture and filter rainwater runoff, reducing storm drain load while watering plants.
Rain Barrels
Collect roof runoff for later irrigation use. A 1,000 sq ft roof generates 600 gallons per inch of rain.
Bioswales
Vegetated channels that slow, filter, and infiltrate stormwater while creating attractive landscape features.
Common Mistakes to Avoid
Don't Make These Errors!
❌ Overwatering "drought-tolerant" plants
Most failures happen from too much water, not too little. Once established, reduce watering significantly.
❌ Planting in summer
Install drought-tolerant plants in fall/winter when they can establish with natural rainfall.
❌ Skipping mulch
Bare soil loses 70% more moisture. Always maintain 3-4 inches of mulch.
❌ Using the wrong plants for your microclimate
Foggy Sunset District ≠ sunny Mission District. Choose plants suited to your specific conditions.
❌ Shallow, frequent watering
Encourages shallow roots. Water deeply and infrequently instead.
Step-by-Step: Converting Your Lawn to Drought-Tolerant Landscape
Assess & Plan (Week 1)
Map your yard's sun/shade patterns, drainage, and microclimates. Decide which areas need hardscaping vs. planting.
Remove Turf (Week 2)
Sheet mulching method: Cover grass with cardboard, top with 4-6 inches compost. Or use sod cutter for faster removal.
Improve Soil (Week 3)
Work in 3-4 inches of compost. Add gypsum if you have clay soil to improve drainage.
Install Irrigation (Week 4)
Set up drip irrigation with separate zones for different plant water needs. Add smart controller.
Plant (Fall - Best Season)
Install larger plants first, then fill in with smaller perennials and ground covers. Water thoroughly after planting.
Mulch Heavily (Ongoing)
Apply 3-4 inches of organic mulch, keeping it 2-3 inches away from plant stems. Refresh annually.
Establishment Care (Months 1-24)
Water regularly for first two summers. Gradually reduce frequency to encourage deep roots.

Frequently Asked Questions
Will my property look brown and dead with drought-tolerant plants?
Absolutely not! Many drought-tolerant plants are lush, colorful, and beautiful year-round. California natives, Mediterranean plants, and succulents offer incredible variety in texture, form, and color. Your landscape can be even more visually interesting than a traditional lawn.
How long until plants are truly "drought-tolerant"?
Most plants need 1-2 years to establish deep root systems. During this time, water regularly (but less than a lawn). After establishment, most drought-tolerant plants thrive on rainfall alone in San Francisco, though occasional deep watering during extended droughts keeps them looking their best.
What about my kids/pets who need lawn space?
Keep a small area of drought-tolerant turf (like UC Verde buffalo grass) where it's actively used, then convert unused lawn areas to water-wise landscaping. Or use durable ground covers like creeping thyme that tolerate moderate foot traffic and release wonderful scent when walked on.
Is drought-tolerant landscaping expensive to install?
Initial costs vary ($5-15 per sq ft depending on complexity), but SFPUC rebates offset 30-50% of costs. More importantly, you'll recoup your investment in 3-5 years through water savings, then save money every year thereafter. DIY installation can reduce costs significantly.
Can I convert my lawn gradually, or does it need to be all at once?
Gradual conversion works great! Start with one area (like the parking strip or side yard), see how you like it, then expand. This spreads out costs and lets you learn as you go. Many homeowners convert 100-200 sq ft per year.
