Sycamore Tree Has Not Leafed Yet and the One Next to It Is Fully Leafed Out

Determining if there is an issue with a tree-due to slow leaf out can be a difficult task.
Cut into a bud-is it brown and dead inside or alive?
Test the branches; do they snap off and break or bend?
Did all the branches bud out?
Failure to leaf out can be due to a disease, root rot or pests.
Cold weather can also effect the buds.
I would remove a few samples of branches and take to your County Extension Office for inspection.
Here are some links for you including a link to help you locate your nearest office.
