Incorporate plants suitable for climate/location
Nurture and protect soil
Prevent/reduce pest problems
Conserve energy/Reduce pollution
Select plants recommended for your Sunset Zone
Microclimates Impact Plant Health and Water Use
2. Scheduling irrigations based on plant needs
3. Making sure sprinklers/drip systems work properly
4. Using mulch and soil amendments effectively

Other Methods to Conserve Water in the Landscape
Minimize the use of water to clean sidewalks and driveways
Don’t Let Water Get Away!Permeable surfaces Infiltration Basins
Mulch Conserves Water and Beautifies Landscapes
Creates flushes of weak growth
Increases water requirement
Avoid Soil Compaction
Keep construction activities several feet from landscape plantings
Incorporate organic soil amendments (except for tree planting sites)
Irrigate Sloped Landscapes Slowly and Deeply to Prevent Runoff
Prevents loss of valuable soil
Prevents Pollution of Ground and Surface Waters
An organic soil conditioner created by decomposing organic matter under controlled conditions until it is stable enough to improve soils without harming plants or transmitting disease.
