*By "cycling" your
irrigation timer to turn on for the suggested number
of minutes an hour apart, you reduce runoff and gain
deeper watering and healthier root growth. Start with
this weekly schedule and increase the times
only if your plants show signs of stress. If stress
occurs only in isolated area, check your irrigation
system before increasing the time. |
**In September, plants water
needs drop by approximately 30 percent even if the
temperature is hotter, for two reasons. First, the
days are shorter, so evaporation decreases. Second,
plants begin to go into a dormant phase where they
need less water. In some years, humidity is also higher,
increasing your level of discomfort, but decreasing
plant water needs as it slows the rate of evaporation.
This rapid drop in water needs will continue in October
and November. |
