Bloodgood maple misshapen leaves
Hello! My bloodgood maple tree did not leaf out completely after a hard winter. I thought it was just delayed but when the tree did leaf out, the leaves were small and misshapen. A weeping Japanese maple in the ground close to it also did not leaf out, and also has very small misshapen leaves. Both were healthy up until the hard winter we just had. My pictures will not post for some reason but I can email. Thankful for any advise.

Thank you for your question. Are you able to upload photos of both trees? A photo of each tree, as well as one of each tree’s leaves would be helpful. Thanks!
Thank you for the photos, Matie. There are a couple of potential 'culprits' in this. First, could there have been any overspray of herbicides while the trees were dormant, or immediately before they leafed out? These often cause distorted leaves (and other tissues) in plants. Here is an article about them: https://pace.oregonstate.edu/courses/sites/default/files/resources/pdf/p0215-0219.pdf
Another potential cause is an insect infestation by mites, leafhoppers and aphids, as mentioned in the article. Have you examined the trees for insects? Of course, they may have already 'moved on' and left their damage, but a close examination may show some signs of their presence.
