I am having trouble with japanese beetles on my Linden tree. The tree is 7 feet tall but new this summer. Will this problem continue for its life? Maybe I should give up now and plant a more tolerant type? I live on a small horse farm and try to avoid insecticides. So far I have been keeping buckets of water around the tree which do capture some beetles but also I put a white sheet around the tree, a couple times a day, then shake the tree and kill whatever bugs fall on the sheet. This won”t work when the tree gets too big! Thank you for your help, Lori
