How old is an oak tree by circumference?
Multiply the diameter by 5.0 if it is a white oak. If the tree is a pin oak or red oak, multiply the diameter by 3.5. The result is the approximate age in years. We stress that this is an estimate – not an exact way of measuring a tree’s age.
Do oak tree roots continue grow?
Do Oak Tree Roots Grow Down or Out? Oak tree roots spread outward more than downward. The majority of the roots that support your oak tree are within the top 18 inches of the soil. The only oak root that grows downward is the taproot, which grows straight down into the soil, typically to a depth of 3–5 feet.

Why are there no acorns this year 2020?
The acorn shortage may be hard on squirrels, but it doesn’t indicate a problem for oak trees. It’s just part of their normal boom-and-bust cycle. Instead of producing a regular yearly supply of nuts, oak trees tend to have a bumper crop every two to five years. Botanists call that a mast year.
Is there an oak tree that does not have acorns?
No — all oaks have male and female flowers on the same tree (monecious). Therefore, all oak trees are capable of producing fruit (e.g., acorns) when the tree reaches sexual maturity.
