Bill from Egg Harbow Twp., New Jersey writes
I have a large Holly tree about 14ft. high and it shows black on the trunk and wood branches but still making new leaves not sure what is wrong.
Bonide INFUSE Systemic Disease Control could be used on holly trees. We could not guarantee the effectiveness becuase we do not know exactly what we are treating for. Please contact your Cooperative Extension Office and speak with the Master Gardener on duty for 100% ID of this pest or disease.
