damage to Engleman Ivy leaves #809765
Asked September 06, 2022, 8:15 PM EDT
I have grown Engleman ivy quite successfully in my back yard (Westminster, CO) for several years. This year the ivy has grown well and sustained itself, and I have seen many flying insets around the plants (pollinating?). However, I have also seen, more than previously, damage to the leaves, presumably caused by insects (see photo). I am reluctant to spray the leaves with anything in case it is harmful to the ivy. Have you any solutions?

First I would like a little more information. Is the plant showing signs of any yellowing anywhere on the leaves? Do you see any signs of webbing, lacey looking, or mildew anywhere? Most pesticides can be safely used on ivy if you use them according to label instructions. I will do further research and get back to you.

hello again
you mentioned noticing "insects" and the leaf damage resembles what japanese beetle would do... do you know if there have been reports of JB in your area?
ROSES, marigolds, zinnias, corn silks, hollyhocks, ivy. You name it; Japanese beetles eat it. These insects use their voracious appetites to gulp succulent rose petals in big bites or skeletonize leaves into lacy patterns.
