Two days ago my maple tree & hydrangea were damaged over the top layer of leaves on both.
Hi - These all have symptoms of cold damage. We have been receiving photos of Japanese maples and hydrangeas like this from all over the state. Many plants were lured out of dormancy and then were hit with the frosts and cold temperatures recently. On some trees we are also noticing damage on the top growth versus the bottom growth. This may be due to warmth from the ground area and bottom growth was not affected. The damaged portions will eventually drop out. If the tree and shrub are otherwise healthy, they will push out new growth this spring/summer. No treatment is necessary.
Keep your plants well watered during dry periods and make sure mulch is no thicker than several inches and away from the trunk/stem. You can send us more photos this season, if you notice additional symptoms.
