Why pay for irrigation when it is free?
Too much water is detrimental to your landscaping, leading to leaf fungus, root rot, and stressed plants that invite insect pests.
Pesticides and fertilizers often get washed out of your yard, drain down the street, and add to lake contamination.
Florida Statute 373.62 requires an automatic rain shut-off device on all automatic irrigation systems.
Sensors usually are matched to the brand of irrigation controller. Hard-wired sensors are more economical and easier to install. Wireless sensors are more costly, but used often when it is not desirable to drill through concrete; or when the time clock is situated somewhat distant from the ideal rain sensor location.
In order to be effective, it needs to be in a location that is unobstructed from receiving natural rainfall. The edge of a roof is the most common place, but a fence post works just as well. It should never be under an eave, under a tree, affected by irrigation, or over an air conditioner.
A more accurate way to determine whether the yard needs additional water, soil moisture sensors are becoming more popular and need to be used properly. SMSs can turn off an individual zone, such as a shady, moist location, while allowing hot, sandy locations to irrigate. Current recommendations are to install one sensor for each “micro-environment” in your yard.
