holly bush browning

Question

Have had beautiful holly bush for several years but recently the leaves are turning brown and limbs seem to be dying. What would cause this?

Answer 1

Browning and dying leaves can be the end result of environmental issues, insects or fungus.

I would do some further inspection.
Remove dead material from the bush and dispose of.
Treat with Neem oil as it works as both an insecticide and fungicide.
