Hydrangeas Part2

So as you know, I bought a hydrangea this past week. I noticed that there was some spoiled foliage at the base of the plant, and I found some mold, probably from all the dampness in the plastic packaging.

I tried to dry it up by placing it in the sunlight and removing most of the dead and moldy leaves, but the past few days my poor little guy got sadder and sadder.

I am scared that it is a fungal disease and not root rot. I hear that they won't die of fungal disease, but they will be sad for a long while. Does anyone know any good tricks to perk up the little guy?

On a side note, I think the kids trampled on my hydrangeas I planted in the front of the house. Mainly because the snow kinda hid it, and when they are playing in the snow, it is hard to notice. I hope they survive, but one really got battered. *sigh*
