I planted two Endless Summer hydrangeas and the leaves are turning yellow and not doing as well as the other two. I am not sure what to do.

We’re happy to help! There are a couple common reasons you’re seeing yellow leaves. You could be overwatering or the soil could be deficient in nitrogen. How often are you watering and how much sun does the plant get? Youl could also get a soil test at your local garden center to see if there are any nutrient deficiencies. If you send a photo, we’re always happy to take a look, too
