Dying hydrangea

Zone Atlanta. Ga | Hampton94 added on October 5, 2018 | Answered

Every year my hydrangeas go into this fast dying phase. They look beautiful and healthy for a month or so and then quickly die. What can I do to keep my plant from looking like this every year. Is it the soil or is it some type of bug? Any help is greatly appreciated. Thank you.

This appears to be a fungal infection. Usually this will resolve itself over winter, but if this is persistent, then you might look at treatment options.

The treatment that I find most broad spectrum, and safe will be the use of dolomitic lime and wettable sulfur together. This will kill off the infection as well as recondition the soil back to a proper pH, and condition.
