![]() Pile them in a corner where they will not bother you and let the squirrels enjoy them. Flowering Oak tree branch with blossoms Image Credit: Jake Foster/iStock/Getty Images Flowering is part of an oak tree's life cycle. You can try using a yard vacuum to gather them, but you will also vacuum up mulch, so you have to decide which is most important. Each group has a different life cycle, but both include flowering, fruiting, seed dispersal, germination and maturation. Drought and insects also play important roles.Īn oak’s age also relates to acorn production, which begins about the time a tree is 20 years old and increases as the tree ages and its canopy (top foliage) reaches a larger span.įor dealing with all those acorns, raking them up is the first thing you can do. ![]() In addition, a late spring frost can blight flowers, which prevents acorn development. ![]() It takes a lot of an oak’s energy and food to produce acorns, so a tree’s health, vitality and resources can impact numbers. This is a big year for white oaks.Īcorn production varies for many reasons, according to other tree experts. Masting takes a lot of energy! Oak trees grow slowly in a mast year and grow well the year after.Red oaks and white oaks typically alternate heavy years.It all begins when a little brown acorn falls to the ground and decides to stay thereIt describes how each season affects the acorn and wonderfully chronicles its development into an oak tree.You'll see its roots stretch, its branches extend and its leaves grow and fall off in autumn. One huge oak can drop up to 10,000 acorns in a mast year! 'Little Acorns' follows the life cycle of an oak tree through the different seasons of the year. ![]() Oak trees of North America annually produce more nuts than all the region’s other nut trees together, wild and cultivated.Oak trees have greenish, inconspicuous female flowers and are wind pollinated.Acorns belonging to trees in the red oak group take two growing seasons to mature acorns in the white oak group mature in one season.There are about 90 species of oak in North America.Oak trees, meanwhile, depend upon boom and bust cycles, and a few uneaten acorns, for theirs. Many animals depend upon the highly nutritious acorn for survival. Unfortunately, more deer and mice may mean more ticks and consequently more Lyme disease. More acorns, for example, may mean more deer and mice. Whatever the reasons and mechanisms behind acorn cycles, mast years do have ecological consequences for years to come. Ultimately, a higher proportion of nuts overall escape the jaws of hungry animals. Years of lean acorn production keep predator populations low, so there are fewer animals to eat all the seeds in a mast year. The fact is, we simply don’t know yet.īoom 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, so they leave some nuts to grow into future oak trees. So what does trigger a mast year? Scientists have proposed a range of explanations-from environmental triggers to chemical signaling to pollen availability-but our understanding is not clear. In other words, weather variables cannot account for the excessive nutty production of acorns in a mast year. But annual rainfall and temperature fluctuations are much smaller in magnitude than acorn crop sizes. Sure, a wet, cool spring can affect pollination and a hot, dry summer can affect acorn maturation. Strangely, mast years are not simply resource-driven. Unfortunately, plants and animals are no better at predicting the future than we are. A mast year is not a predictor of a severe winter. Scientific research can tell us what a mast year is not. But the why and how of these cycles are still a mystery. Boom times, called “mast years,” occur every 2-5 years, with smaller acorn crops in between. Like many trees, oaks have irregular cycles of boom and bust. 10 Botany (Taxonomy, Nomenclature and Morphology).
