I have finally planted some grape vines which is something I have been wanting to do for years. I built a couple trellises out of 16 ft. cattle panels that worked great. The vines just about covered the whole thing by mid summer and were looking wonderful. One day, I went out and noticed several Japanese Beetles chewing holes in the leaves. I crushed the ones I could get to. The next day there were around a hundred all over my white grape vines. It looked like someone took a shot gun and blasted away with bird shot all over them. I sprayed two different Japanese Beetle insecticides which seemed to drive them off but it seemed they would come back in a couple of days. What makes it even worse was the "perverse acts" they were performing on each other all the while eating away at my beautiful grapes. A couple of times I believe I could hear them laughing at me. I was so mad, I wanted to just pull the last hair out of my head!
So.....................sorry. I'm trying to calm down. So, anyways, I was reading online about these floating row covers that are used on various plants to keep these @$#% bugs from devouring them. I haven' t found any information on anyone using floating row covers on grape vines. Plus, I was wondering how the bees get to the flowers to pollinate them with these covers on.
