Hi..I noticed a couple of days ago that the newly emerging leaves have turn brown and are curling a bit and feel dry. This has never happened. The tree goes dormant every year and this is the new spring growth. We had an unusually hot day pop up, in the 90's the day I noticed. Is this a disease or leaf burn? Can leaf burn happen if the leaves are new and a very hot day hits? Help!

Thanks!

Theresa
