Irrigation is critical in Cincinnati. When the Spring rains hit it's great. But there's a point in July or August where the rain stops, they might get a
half inch of rain in 2 or 3 months. So, without a backup you can't get the beds to look good. It's a very inexpensive insurance policy. They don't like
to irrigate to just water, they water very carefully. This is a very intelligent use of water.
