Guys-
I am wondering if anyone of you here are gardening pros? I have several hydrangea shrubs which are two years old and they seem to be struggling recently. I also have some seedlings which I am going to try and grow indoors this winter.
If any of you could throw me a few pointers on growing these beautiful plants I would really appreciate it. Maybe you have a favorite website that may help me out (keep it clean please!

)
I just fear there is something I should be doing to the outdoor shrubs like pruning or fertilizing to help them get ready for the cold....
Many Thanks, Hooper
