I have a one year old Clasrastis kentukea seedling. About 5' tall.

Today, noticed that a few of the leaves have either some brown blotches on them, or a little dried out/curled up at the ends. It wasn't like this even three days ago.

Any thoughts?

Never mind the staking, I'm trying to train a single leader. I know they don't like to have tall trunks, but I figure if I can get a leader up to 5 feet, I can just let it go starting next year.

By the way, does anyone know how to post directly from the Houzz mobile app? I can upload pics and reply to threads I've posted in, i'll be damned if I can figure out how to start a new thread on it.

Yet on my iPhone, I can't post pics from the browser. So I have to start a thread on the browser, then go to the app and post the picture.
