The Q&A Archives: mixed colors with endless summer hydrangeas

Question: Hi. I recently bought one of your large endless summer hydrangeas and I love it. I especially love the mix of blue and pink blooms on one shrub. Can you please tell me how I can achieve this look next year too? I know that adding acid to the soil in spring can create blue blooms but I don't know how to achieve the mix in one plant. It is beautiful! Thanks, Cindy

Answer: The mix you are seeing is probably due to the plant being in the process of rooting outward from the original soil mix into the native soil. Your local soil is probably quite acidic so encourages the blue coloring, the potting mix have been treated with lime to make it slightly less acidic and therefore encourage the pink. I would suggest you wait several years and see what color your hydrangea eventually settles into displaying, and then adjust if desired. It is not at all uncommon for new hydrangeas to display a varying range of colors. Enjoy!
