Q: I have a tree in my backyard that must have been planted by the previous owners. I’ve tried to identify it through The National Arbor Day Foundation but I can’t figure it out.

Can you look at these photographs and let me know what kind of tree this is?

A: Certified arborist Shannon Pable says it’s a mockernut hickory, Carya tomentosa.
