Xeriscaping Steps for Seaside
1. Plan and Design
Start with a water-efficient landscape plan that groups plants by water needs. Place high-water plants (if any) closest to the house and low-water plants further away.
2. Improve Soil
Amend soil with compost to improve water retention in sandy soils and drainage in clay soils. Healthy soil holds more moisture and supports deeper root systems.
3. Reduce Turf Area
Limit conventional lawn to areas that serve a functional purpose (play areas, pathways). Replace decorative turf with native plants, ground covers, or mulch.
4. Choose Low-Water Plants
Select native and adapted plants suited to your USDA zone. Native plants have evolved with local rainfall patterns and typically need no supplemental irrigation once established.
5. Mulch Generously
Apply 5–10cm of organic mulch (or gravel in desert climates) around all plantings. Mulch reduces evaporation by up to 70%, suppresses weeds, and moderates soil temperature.
6. Irrigate Efficiently
If irrigation is needed, use drip systems or soaker hoses rather than sprinklers. Water deeply and infrequently to encourage deep root growth. Water before 9am to reduce evaporation.
7. Maintain Appropriately
Proper maintenance reduces water waste. Keep mulch refreshed, prune to reduce water demand, and adjust irrigation seasonally. A well-maintained xeriscape improves over time.
