Magnolia leaves are curled
My 10-year old magnolia bush/tree(think the name was "saucer") bloomed as usual this year, but most of the leaves are now curled(see photos). I've checked the inside of the curled leaves for bugs and haven't seen any. Just to make sure I sprayed it yesterday with Captain Jack's Deadbug (spinosad). Any other suggestions/diagnoses? The tree has been very healty every year. Thanks in advance.
