Are Your Trees Dropping Green Acorns Like Crazy?

Green acorns? What does it mean, and what does it mean for the upcoming winter?

Do falling acorns have anything to do with predicting the weather? If you have oak trees in your yard, you are probably familiar with the task of raking up tons of acorns in the fall. However, sometimes many small green acorns fall from oak trees like crazy, even in the middle of summer. What does this mean and does the amount of green acorns mean anything about winter weather?

Acorn - Oak
Green acorns on an oak are a common sight in summer.

Typically, acorns fall during the autumn season, serving the purpose of planting new trees and providing food for critters. However, if green acorns are dropping prematurely, it indicates that the tree is stressed due to adverse weather conditions.

Normally, acorns ready to drop are brown or tan. Premature shedding suggests that the trees are prioritizing other tasks over seed production.

Summer Tree Stressors

A tree’s stress can be from too much rain, too little rain, a too-hot summer, or other factors. But it’s usually dependent on local conditions. In fact, just like “mast years” can happen in Virginia but not in neighboring North Carolina, the same is true for stressed-out trees dropping green acorns. It’s not happening everywhere.

Acorns and Winter Weather Folklore

Acorn - Oak

In our article, 20 Signs of a Bad Winter Coming, we delve into the folklore surrounding nature’s indicators of harsh winter weather. One such sign is the profuse dropping of acorns, which typically refers to brown acorns falling during autumn months. According to tradition and lore, seeing an abundance of brown acorns falling means a severe winter is predicted.

South central Michigan. Lots of small light brown acorns. Seem to be very brittle. Break into pieces when they hit the ground. Then it’s like walking on glass cause of the sharp pieces

Stood under an oak today whilst it dropped lots of green acorns, in Aberdeenshire Scotland. I was looking last year but there was none. Now I find they are no use for planting. Sigh.

We have had tons of mainly green acorns falling since mid August. We live in central Maryland.

Here in Southern Ontario we have had unusually hot and humid weather, in excess of 40 degrees Celsius for weeks at a time. Went for a walk with my daughter yesterday and passed a bunch of Red Oaks- they were shedding green acorns like crazy. I gathered them up and thought about spouting them, but they’re immature and they will not germinate.

Tons of green acorns have been falling at my house for about 2 weeks and it is Aug.14,2025. We have 6 acres of all kinds of oak trees, so there are small, skinny and large acorns. Also, a lot of sap/pitch is dropping. I live in N. Calif. Not sure why the sap this year.

Loads of green acorns and some brown ones dropping in my garden from neighbouring oak trees from late July and throughout August. I live near Twickenham in London, England.

I live in Northern California. I have tons of acorns. The wild animals can’t keep up with what is on the ground. I can’t let my horse out of the barn due to all of the acorns on the ground. I pick them up regularly, but when you have 6 acres and work full time Ican’t get to all of them.
