[QUOTE="muttmeister, post: 184159, member: 135"] If you live where it is cold in the winter, as I do, hydrangeas will die back in the fall and reemerge in the spring, although you should have seen a lot of growth before now. If your hydrangea is one of the old fashioned kind, and it dies back in the winter, you probably won't get any blooms as they only bloom on second year wood. However, if it is one of the new cultivars, like Endless Summer, it should bloom as they bloom on both old and new wood. To get it to have blue flowers, the soil has to be acidic. I use aluminum sulfate, available in any garden store. I've been told that adding coffee grounds around the roots has the same effect, although I've never tried it. There is a neat Sue Grafton/Kinsey Milhone book where she finds the body which was buried in a car many years before by realizing the hydrangeas were blue and the rusting metal was what had made the soil acidic. Sorry, I'm rambling. You can get lots of good info about hydrangeas on the internet or from your county extension agent. [/QUOTE]
