Water Use - Cut in Half Newsletter
How to Cut Your Water Use in Half
Most homeowners and commercial property owners water too much. Many turf and other plant problems are related to this issue. How often should you be watering now? I don’t know - it depends on your location, the soil, plant types, organic or synthetic program, etc. Hopefully you are organic and thus have lower water needs. Here are some other tips:
First, turn the irrigation control off automatic and on to manual. Then the system won't run unless you push the button. You’ll save lots of water, the soil will be healthier, and your landscaping will look better. This is as much a no-brainer as not catching the grass clippings in order to feed the beneficial microbes.
Water deeply and infrequently as possible so that the soil pulses or breathes. About 1" of water per week in the summer is a good starting point. Then adjust from there. Light, frequent watering of grass and other plants produces weak, shallow root systems that encourage weed invasion and does not effectively use soil nutrients and moisture. Ideally, it is best to water just before wilt begins. Early morning is usually the best time of day - late afternoon is the worst. Morning is usually the coolest part of the day and when wind is lowest, and there will be less waste through evaporation. For trees, soak them deeply once a month if conditions are dry.
Go organic. The single most effective way to save water is to go organic. Healthy plants in healthy soil have healthy biodiversity of beneficial soil life that expands the root system to be more efficient at accessing water and nutrients.
More water saving tips:
1. Plant adapted plants - natives are best.
2. Use compost, earthworm castings, organic fertilizer and dry molasses.
3. Avoid synthetic fertilizers and toxic chemical pesticides.
4. Add volcanic rock minerals - i.e. lava sand, zeolite, basalt, azomite, etc.
5. Mulch all bare soil with shredded native tree trimmings.
6. Water at night or very early morning for best results. No that doesn't encourage disease - it rains at night.
7. Be careful of drip irrigation. Water has a habit of seeking the path of least resistance. The result can be wet and dry spots. Above ground sprinkling is usually best but the pressure should be adjusted so that "fogging" doesn't happen.
Again - the most important point of all is to use an organic program. Healthy soil contains bacteria, fungi and other beneficial microbes that hold and use water very efficiently. The roots of plants in healthy soil are greatly expanded by the growth of microbes, especially mycorrhizal fungi. It’s all as nature intended.
Corporate headquarters, golf courses, commercial and residential landscapes, and public gardens can save about 40-50% on water use and related costs by using an organic program.
