No Black Walnuts This Year

The black walnut tree leaves and flowers were looking good before our freeze a couple of weeks ago. Two nights with temperatures in the middle twenties did them in -- completely.

How badly a tree's leaves were damaged seemed to depend upon its stage of new leaf growth. Those whose leaves had been on for a little while faired okay. Sweetgums show little damage. Hickory, black walnut and red oak got hit the hardest, losing all their new leaves and, even worse, flowers. The hickory began recovering quickest, with new leaf buds erupting only a few days after the freeze. I'm just now beginning to see a few new leaf buds on the red oak and walnuts.
