Did you know that most gardeners overwater by 20-50 percent? Or that up to 80 percent of plant problems are related to incorrect watering? If you’re not sure how much water your garden needs, the Marin Municipal Water District’s FREE Weekly Watering Schedule can help.
Many people turn on their irrigation systems full tilt as soon as the rainy season ends. But over the course of the summer your plants’ water needs will vary a lot depending on weather conditions, day length and other factors. By adjusting your irrigation schedule weekly to give your plants just what they need, you’ll save water and money while maintaining a healthy garden.
MMWD employs three high-tech weather stations—one in each of the three different climate zones in our service area—to continuously monitor air temperature, humidity, rainfall, wind speed and solar radiation. This information is used to calculate the rate of evapotranspiration (ET)—that is, how much water is being lost from plants and soil into the air. MMWD crunches this data to produce the watering schedules, which let customers know how many minutes they need to run their drip or spray irrigation systems to replace lost soil moisture.
There are four ways to get the schedule:
