B) Soil amendments
One factor that tends to receive too little attention when designing a landscape is the soil that serves as the base for the project. While it may be hard to get excited about dirt, itís a good idea to consider amendments when not blessed with ideal loam.
Most local soils are largely clay, which inhibits the penetration of water, and limits air spaces in the soil that plants need. Since itís easiest to improve soil before plants and irrigation systems are in place, itís well worth giving attention to at the start.
Most beneficial is the generous addition of organic material, tilling it well into existing soil. This will provide nutrients for plants while also helping soil absorb and retain water.
