We bought a house with hydrangeas and I asked a lot of questions also. The first year I did what some people said and I only cut the dried blossoms off a right before or after the first freeze(I forget) and not much stem, my hydrangeas were much too long last summer. So last year I cut the blossoms off again in the fall and about 1/2 of the stem got snipped off too. I'm much happier with the looks of my hydrangea plants this year. I have not put any fertalizer on them. But I'll ask about this at the local garden store. Good-Luck (05/14/2007)
I do very very little to mine. In the spring before they start to "leave" I snip off all the dead flowers and anything that looks "yucky" I want mine big as to block the view. I don't feed them anything, they are very hardy. I live in WV, it may be different where you live? (05/15/2007)
