we have a new red maple planted, about 4 weeks ago, its about 11 ft high. has new baby leaves,, temperatures got down to about 32 last night and we had a light frost, the leaves today are mostly green still but have a few brown spots on them, we have a year waranty on the tree but dont want to have to take it back if its not ruined. how can i tell if its damaged or not. we have another typle of none fruit bearing pear tree on the other side of the yard and it looks fine,, our maple doesnt look bad the leaves arent black or fully brown.. how can i tell... thank you so much for the info
