I have a hydrangea that bloomed wonderful for two years and then last year, it didn't bloom at all. I missed those beautiful blooms so much! I have done some research on the web and it seems to say that if a frost comes in late spring then it can make you not have blooms so I decided thats what happended last year, so this year I have been covering it at night when frost is possible...but my greenery is only coming up from the ground, not on the sticks...I read that is bad, that frost might have gotten it...I have never pruned it at all. WHAT DO I NEED TO BE DOING TO GET BLOOMS EACH YEAR? SHOULD I COVER THEM UP IN THE WINTER AND SPRING? I am stuck, how do I get my plant to bloom again? Thanks so much!
