I put miracle grow on hydrangea plant. watered with miracle grow from top of plant to bottom. now it looks like it is going to die, what can I do to revive it?
Your plants may have been burned by the fertilizer.
You an try washing the plant with a spray of water.
Fertilizer can burn the foliage and the roots. It can kill the plant.
You will need to wait and see how the plant progresses.
