Tree Stress and Reproduction
Our 100 year old oak trees (about 20 of them) did not
produce ANY acorns this year. Why is that?
Sometimes they do not produce acorns:
perhaps due to environmental factors.
Anthony Brach Ph.D.
Acorn production varies from year to year for a number of reasons, including
moisture and other weather conditions. Most oaks produce abundant acorn
crops in cycles of 2 or 3 years, and the cycle may be in effect for most or
all trees in a given area. It may be a bit unusual to find NO acorns in one
year, but if it was a "down" year of production cycle and weather or other
stress were added, then the tree might not produce acorns. Trees live a long
time, and have evolved to reproduce over the long term, not necessarily
