rose coloring on hydrangea
What causes the reddening on tips of hydrangea. Looks like sun and heat but it's dark pink, speckled and where it get's the most sun.

Thank you for your question. It is difficult to diagnose a problem without a photo, and I'm not understanding whether the reddening is on the tips of the flowers or the leaves. Here is a link to an Extension article about various problems with hydrangeas, but it you don't see a photo of an identified issue that matches your plant, please send photographs: http://www.aces.edu/pubs/docs/A/ANR-1212/ANR-1212.pdf
