Burr Oaks

I have two burr oaks that I planted together ten years ago. They are of equal height and seem equally healthy, BUT: One of the two seems to always be a full month behind the other,every spring, in developing its leaves. AND: As I look out on my yard right now, that tardy tree has already shed a good seventy-five percent of its leaves, while the other has all its leaves and is just starting to turn brown. So, I've got one tree that grow its leaves one month later and drops them one month sooner than the other. I wonder why....
Any insight or comments would be welcome. Thank you! |

| the genetics of open pollinated acorns.. dictates that they might not be EXACTLY genetically the same ... thats my guess.. and i am sticking with it .... it might be interesting if you could post pix.. and see if the tree nuts will confirm the ID .... maybe they will see something in the leaves to give you ideas about the crosses ken |

| assuming that they were planted right etc...Seed provenance(place of origin) can play a role in what you describe. eg. one coming from Texas and the other from Oklahoma. |

| Genetic variation. That variation can be derived from provenance as dricha says, or within the same provenance by simple Mendelian genetics. Dan |
