Why do southern Missouri oaks bear more frequently and heavier crops than oaks in northern Missouri? It obviously isn’t soil quality. Do you think it might be minerals that are more readily available in the Ozark rock? The white oaks and swamp white oaks bear very infrequently in spite of releasing them with chain saws and even fertilizing. These oaks range from 20 to 100 years old. The only oaks to bear a decent crop are pin oaks.
Thanks in advance,
I suspect it’s due to later frost dates in the north. Oaks produce flowers and the flowers make acorns. If the flowers are damaged by frost, they won’t mature into acorns.
