Korean hornbeam

[flor1]

I've got a korean Hornbeam in a grow box that I got this spring. My question is it early for the the leaves to be starting to change color noticed a change today turning a light yellow on the edges. Thanks for any help.

IT depends on your location... (might want to add that to your profile)... but for the most part a lot of people are seeing the beginings of fall color on some of their trees right now this year. My amurs have already started to turn red on some leaves and my euonymous are doing the same on a few leaves. I don't think its much to worry to about but you should be an eye out for any other signs of weakness.

pictures always help in these cases as sometimes people spot problems you might not have noticed.
