We treated a crabapple tree which has hostas below it. They look wilted and are yellowing. We used it a year ago, and they seemed fine. This year my husband treated the tree twice and now our hostas are not doing well.
Fung-onil Multi Purpose Fungicide Concentrate should not harm hostas if applied according to the instructions on the product label. We would recommend contacting the manufacturer directly for further advice. You can reach Bonide at 315-736-8231.
