Pin Oak loves wet feet. In fact, when we find it in the wild, it is always near a water course, on the flood-plain or in a wet depression of some kind. The yellowing of the leaves during the mid-summer months is usually due to it being placed on a site that i ... s not suitable. The form of Pin Oak is quite nice. Its lower limbs hang low, and its crown is tightly branched. The red, yellow and orange fall colors can be stunning, but if the tree is not placed properly, it goes straight to a light brown. The perfect oak for wet yards or pond areas.
