There are many questions about why some trees in the same block or surrounding area are fully leafed out following the freezing event in February and why some trees are struggling to come out. The answer to this is complicated. Oak trees are propagated from acorns and each tree can have a different progeny. Trees are like us. We are all human but have a different gene pool and just as we react differently to stress and disease, so do these trees. Some trees of the same species are more tolerant to the stress of the freezing temperatures.
