75+ yr old holly bush shrubs with all brown leaves. Never noticed this before in 19 yrs lived here (northern PA). Can see small amt of new growth appearing in spots underneath. What to do? Prune them back n remove dead leaves or just let them go and see what the next few weeks bring? Should I add some miracid to the soil?
In our area, this has been the “question of the year:. HERE’S a link to a blog post abut what happened and what you can do about it.
