Once the tree is mature enough to produce acorns is should produce them every year.
The pollen is to produce acorns, which produce more oak trees.
Most trees that fruit heavily one year will take a rest the following year and produce little fruit
Acorns are the fruits (seeds) produced by Oak trees. The Oak tree will attempt to grow acorns every year. In some years the conditions for them are better and others but there are always some.
Factors such as weather conditions, availability of resources, and the tree's natural cyclic patterns can influence the production of acorns from year to year. This natural variability in acorn production is a strategy employed by oak trees to ensure survival and reproduction in changing environmental conditions.
Oak trees typically take around 20-50 years to produce their first crop of acorns. The ability of an oak tree to produce acorns can also depend on factors like the tree's health, environmental conditions, and species of oak. Once an oak tree begins producing acorns, it can continue to do so for hundreds of years.
Oak trees drop their acorns in the early fall. Pollen carries through the air in the spring to make acorns.
Yes, acorn woodpeckers spend most of the year storing acorns in holes they drill usually in oak trees. They eat the acorns over the winter.
Oak trees are composed of two main species types White and red with many sub species falling under both groups Of both main species types neither will quit producing acorns after maturity. However they will skip years depending on soil moisture and climatic shifts in climate and weather patterns. Stress caused by these factors may cause some species to not produce in certain years but this is typical. Red oaks are more prone to drought stress as they tend to have a shallower root depth and lack the long tap root that most white oaks have. Stress from drought and a late frost which hits after a tree has budded and began its pollination process is the leading causes of crop failures. Repeated stress on an old mature tree as well as limbs falling off due to heavy foliage can cause fungi to set in which will ultimately lead to disease and death of mature trees.
To make paper
because it is going to be a touch winter this year.
There is a very detailed section in this web page about the acorn production in relation to the age of an oak tree: http://www.arcytech.org/java/population/facts_oaks.html But simply, a fully grown oak tree (about 150 years old) will produce about 2200 acorns every year.
