will hydrangea survive in a pot?
I have a large (24" ?) old barrel pot out back with nothing in it in the shade. My DH saw a hydrangea and wants us to buy one for the pot. I have a couple questions:
Will it survive in the pot through the winter? (we're zone 5 in northern NJ)
How long do they bloom for? (I can't remember as I've never owned one yet)
Should I add the alkaline in the fall to ensure the blooms are blue next year?
