Q.reducing scale and lacy leaves

Zone Fitchburg, WI | Kelli J Kreienkamp added on March 29, 2018 | Answered

Last year our Linden was covered with scale on the leaves, and all the upper most leaves were being eaten to the point of nothing left but the veins. I have considered using dormant oil. Is this recommended for a Linden? Is it too late to apply? I live in Wisconsin (Madison area).

You should only apply this when the tree is completely dormant. If there is any sign of growth, then it may be safer to use neem oil. Just don't spray while it is in direct, bright sun. Wait until afternoon, or a cloudy day.
