The dry weather that started last summer has continued through the winter and spring and now into the summer of 2012. Since April 1 we have received only 6.25in of rain. The lack of rain in combination with the high temperatures and strong winds last few weeks has put some of the plants under stress.
At the University Display Gardens we are lucky to have access to irrigation. Our water is from a onsite well. Near the top of the gardens we have connections to a water line. To this we connect a series of 30 ft aluminum pipes, each with an elevated sprinkler head. We connect enough pipes to reach desired beds.
We try to maintain an equivalent of 1.5inches of rain each 7-10 days. With our irrigation system in place this takes approximately 1.5 hrs for each run. We then have to move the pipes to the next rows. All together irrigation is an all day affair. It takes a lot of work. So in essence we are always hoping for rain. There is no substitute for rainwater to make plants grow.
