For the past two years we have had attacks of leaf spot which have fully defoliated our tree around the end of summer. We're hoping to treat in early spring and again as needed to prevent this next year.
We would recommend contacting the Master Gardener with the County Cooperative Extension office for recommendations on the most effective fungicide for treating and preventing leaf spot on mulberry trees. We do carry Bonide Liquid Copper Fungicide Concentrate which is labeled for leaf spot on fruit trees however mulberry is not listed so we cannot advise that be used.
