Hydrangeas look burnt
Our lime light hydrangeas look burnt this year. Many of the leaves are shriveled and some of the blooms look brown. We fertilized with organic espoma this year. This didn’t happen last year. Wondering if they haven’t received enough water?
Was any type of herbicide applied around the area of your Hydrangea this year or last fall? A symptom like this can occur from herbicides -- including drift of herbicide from nearby locations. All you can do is prune out the abnormal growth and wait to see if healthy new growth develops. Here is more information about herbicide injury. https://extension.umd.edu/hgic/topics/herbicide-damage
Thank you for the response. We haven’t used any herbicide this year or last year. I’m stumped. Could it be too much espoma fertilizer? Or not enough water?
Too much fertilizer would result in fertilizer burn -- scorching (browning of the leaves). Insufficient water would not cause this type of curling/bronzing of the top leaves. If a neighbor applied an herbicide, sometimes products can drift or volatilize and cause this type of symptom of broadleaf plants. In any case, the recommended action is still the same -- prune out the damaged portions.
