Concern about leaves turning mulberry color on maple tree
We have a large maple tree in front of our house that has leaves on it turning a mulberry color. This has been going on for about 3-4 weeks. We have lived here three years and never seen this before. The color change is spreading, but we are not losing leaves. We are wondering what is going on. What causes this? What can we do to stop it? We are concerned that if this indicates a big problem we may lose the tree. Thank you for your help. (We have noticed this kind of change on only one other tree on our block and it is only a couple of leaves.) I have sent photos of our tree, however did not know how to upload, so sent the pictures separately. I hope this works. Thank you for your help.
Pay attention to changes in plants, such as leaves turning color during the last couple months of the summer. These types of indicators are a red flag that needs attention. Not all injuries can be corrected, but the impact of the stress can often be reduced by watering heat or drought-stressed plants. It can be minimized through the proper use of mulches to help reduce the loss of water from the soil and also to protect roots from quick changes in soil temperatures. Careful inspection of the plant may show insect damage that if caught early may prevent needless injuries.
