Avoid frequent, shallow sprinklings that lead to shallow root development. Compact soils result in quick puddling and water runoff. They need aeration with machines that pull soil plugs. Trees and shrubs separate from the lawn are best watered with deep root watering devices. Xerimulch the Landscape Properly selected and applied mulches in flower and shrub beds reduce water use by decreasing soil temperatures and the amount of soil exposed to wind.
Mulches also discourage weeds and can improve soil conditions.
Organic mulches include straw, partially decomposed compost, wood chips, bark, and even ground corncobs or newspapers. Inorganic mulches include plastic film, gravel and woven fabrics. Sometimes a combination of both organic and inorganic is used. If soil improvement is a priority, use organic mulches. Wood chips and compost are most appropriate.
