Wet Spring Delays Kimberly, Aberdeen Weed Research Tours Until June 22, 23

TWIN FALLS, Idaho – Even weeds are slow to grow in the cold, wet weather across Idaho this spring, says Don Morishita, University of Idaho professor of weed science and extension specialist at the Kimberly Research and Extension Center.
Plants are growing so slowly that the annual Kimberly Weed Research tour will be delayed a week until June 22 as will a similar tour at Aberdeen June 23.

"We've had to delay the tours because it's so cold and wet here that everything's behind," Morishita said.The University of Idaho Snake River Weed Research Tours will be held at the Kimberly Research and Extension Center at 3806 North 3600 East near Kimberly and the Aberdeen Research and Extension Center at 1693 South 2700 West near Aberdeen.
