In recent years California has experienced lower than normal rainfall. Although, always a concern, water use has, in recent years, become an issue that is front and center. One of the major uses of water is irrigation and of all the plant materials in our landscapes, turfgrasses use the most. In order to conserve water, limit fungal diseases and promote the over-all good health of your lawn, the following practices should be incorporated:
1. Deliver 2 to 1 1/2 inches of water to your lawn weekly.
2. Water in the hours just prior to dawn to reduce loss due to excess evaporation, yet allowing the moisture to evaporate from the leaf blades in the early part of the day. This aids in reducing the incidence of fungal disease. Alternating watering days is another way to allow proper drying to discourage disease.
3. Water on alternating days, three days per week: Divide the amount of time it takes to deliver the required amount of water by three. This tells you the amount of time to water each of those three days.
4. Rather than deliver the entire daily amount of water at once, divide your watering up into two or three cycles of your system. This will minimize runoff and maximize absorbtion.
