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 every year.
