Q. Some oak trees are producing heavy crops of acorns this year while others aren't. Do acorns have on and off years as far as production is concerned? We have a couple of huge oak trees and once ...
Why do oak trees produce more acorns some years but not others? Many factors influence acorn production, even within a 100-mile area.
Flower Production. In the spring, oak trees produce often unnoticed yellowish-green flowers. Oak trees are monoecious, which means they produce both male and female flowers on the same tree. This gives every single oak tree the ability to produce acorns. Rising temperatures trigger the flowering of oak trees.
Boom and bust cycles of acorn production do have an evolutionary benefit for oak trees through “predator satiation.” The idea goes like this: in a mast year, predators (chipmunks, squirrels, turkeys, blue jays, deer, bear, etc.) can’t eat all the acorns, leaving some nuts for growing into future oak trees.
Production of acorns increases each year in proportion to the size of the oak tree's canopy. When oak trees reach near 100 years old, the acorn production slows to a yearly rate of 2,200. Even though oak trees have both male and female flowers, they still need neighboring oaks to pollinate.
Oak Propagation. Oaks adhere to different acorn production cycles based on their species. White oak acorns mature in one season, while acorns of the red oak need two seasons to reach maturity.
Oak trees produce acorns once per year. The number of acorns produced can vary from a handful one year to a large amount on what is called a "mast year." A theory that explains the excessive fruit production is predator saturation, when the tree attempts to produce more fruit than can be eaten by predators.
Growing Acorns. If you would like to propagate live oaks in your yard, gather acorns only after they fall from the tree. If an acorn rattles when you pick it up, the seed will not grow.
A tree's life cycle will develop differently and an oak tree life cycle is no different. With the right soil, acorns can germinate during the early spring. Fast forward to the final stages of maturation oak trees can develop into a sapling tree after four or five years and live for hundres of years.
