How can you tell the difference between a newly growing walnut and pecan tree? I have a pecan tree in our yard, however also a walnut. The pecan is much older but the younger tree is hard to define between the two? Does anyone know of any easy way other than waiting for them to produce!
and maybe by the bark.
The shape of the leafs, both are almost the same... but had a look here:
Actually, a pecan is botanically called a drupaceous nut.
But I don't know about walnut.
