Bingo! I think you have figured it out. It definitely looks like a Hawthorn. I bet one of our many bird visitors transplanted it by droppings. I think that I will keep it since the wildlife seem to enjoy it, but maybe I can try moving it to a different area of the yard since it is very close to my walkway right now. Thanks so much for the help!

i am in adrian mi ... prime planting time in MI ... is ground thaw in late march ... minimum 6 to 8 weeks before leaf out ... OR!!!!! and late sept thru about now ... so this is your window of opportunity ... for next year ... gee tree farm is just north of jackson MI ... off I-94 ... with a 15 acre arboretum .. and hundreds of acres of trees... it would be a brilliant trip ... NOW ... call ahead... ask for cary ... and explain what you are looking for .. and ask if their field trees are still holding leaves.. and if you could mark some for next summer .. it might require a deposit ... and that is up to them ..... [i would have you mention my name.. but i dont know if it would be a positive.. lol ] .. make an appointment for someone with a golf cart to whisk you around the property .... you might be able to find some out your way also ... google tree farms grand rapids ... the larger the tree.. the more roots you cut off to transplant ... no tree will perform to expectations until it regrows its root mass .. so a larger tree.. will take years longer to recover ... smaller will get 'established' faster .. and can outgrow a larger specimen.. inside 5 years .. not to mention.. if you are doing this yourselves.. how to move.. transport ... carry.. and plant.. a humongous ball and burlap.. sans heavy machinery ... i have tried that.. nearly ended up needing surgery .. not cool ... my dichotomy.. is based on you doing it.. versus big checkbook professional installation ... its not that it cant be done... its what can be done in your budget .... i am impressed you are so far ahead of the curve... usually peeps want instant gratification.. rather than planning a year out ... should you be thinking of doing this yourself.. read.. digest. and commit to memory.. EVERYTHING at the link ... doing it the right way... really matters .... ken Here is a link that might be useful: link

I would contact the nursery you bought the trees from. It almost looks like something that was sprayed on the trees, and not a disease. Just to make sure they didn't spray something on the leaves that now might be causing this discoloration or burning. You can also try contacting your local ag agent and send them the photos to see if they can ID the issue for you. Patty S.

Not so sure this is a nutrient deficiency, since just a few leaves appear to be affected. If it were a micronutrient deficiency, you would see a much more pervasive chlorotic appearance. Cali, are these affected leaves more in the interior of this very dense tree? If so, it could be some fungal infection, that may not be so much an issue. I would try to open up the canopy to get better air flow. Remove any crossing branches inside the canopy. And, I would make sure if you're getting hard freezes in your area, you might want to consider not applying any more fertilizer at this point, but instead, apply a micronutrient foliar spray, instead. If you give your tree a big shot of nitrogen, you're going to have tender new flush coming out in a month or two that may not survive your next frost. I would be more inclined to fertilize in February, April and July/early August. I'm thinking Labor Day may just be too late for your area, for your last application if you're getting these kinds of freezes. Just a thought. Patty S.
