The Q&A Archives: Hydrangeas

Question: I live in Georgia. What can I do to keep my hydrangeas pink ?


Answer: Hydrangeas remain pink in alkaline soils and turn blue when the soil is acidic. It takes a while to change the soil's pH, but it can be done. If your soil is acidic, you'll want to sprinkle lime over the soil surface in the fall (it takes a few months to works its magic). If your soil is sweet, or alkaline, you won't need to do anything to keep the flowers pink.

Good luck with your garden!
