Why Aren’t Oklahoma’s Cottonwood Trees Making Their Usual Mess?

Every summer, I fight the same battle.

Normally, by the middle of June, I'm fighting back against the mess of my neighbors' three huge cottonwood trees as they spread their fluffy seeds into the air. While I do get a kick out of lighting the big line of "cotton" that accumulates along the driveway, watching it burn down to the street, I really hate the constant maintenance I have to do to my outdoor AC unit to keep the coils clean.

Now here we are in the dog days of July, and those three mature cottonwood trees have yet to even produce seed pods.

It's like the trees are taking the year off. Even stranger, it's not just the cottonwoods.

You know those really messy whirly-bird seeds that usually cover everything in the spring and early summer? Those are maple tree seeds... and yet I haven't seen a single one of those either.

You might think it's weird, but I usually look for those seeds every spring. I like to pot them and make seedling Christmas presents out of them, but not this year.

It's Not Just Southwest Oklahoma Either

I was talking to my dad about this phenomenon last night. He hasn't seen any either.

Not in the neighborhood, not even around the lake. It's curious enough to make him take notice.

In fact, he fishes his local lake at least four days each week. The glorious lives of retired people... and he did mention that the normal underwater vegetation - grasses, weeds, reeds, etc - hasn't sprouted out of the water yet.

At This Point of the Year, That's Weird

So we started flinging theories back and forth to each other and came up with a probable reason Mother Nature isn't reproducing in 2026...

This has to be directly related to the weirdest winter we all just experienced together.

Outside of that two-week stretch where Oklahoma got buried under snow and ice, it barely felt like winter at all.

From November to April, it was a perpetual Spring in the 60s and 70s. We took the boat out over the family Christmas break and New Year's. Like a miracle across Oklahoma.

So... Did an Unusually Warm Winter Confuse Oklahoma's Trees?

I looked into it, and as it turns out... maybe. It could definitely be a big factor in why we're not seeing as many seeds and other signs of nature reproducing this year.

Science says seed production depends on a whole laundry list of things. Winter temperatures play a big role, but so does spring weather, pollination, rainfall, late freezes, and even the tree's own natural cycle. Some years, trees simply produce far fewer seeds than others, even when they're perfectly healthy.

Lots of plants need a good stretch of cold to reset the biological clocks of plants. If you like to grow things, you know about stratification - the cold cycle some seeds and most trees need to germinate.

In the same way, trees need a cold dormant cycle to reset the clock, and it appears we skipped that with our perpetual spring.

Same Old Science

A million reasons to disprove a theory, and nothing conclusive except the opinions of enough of your peers.

I've lived here long enough to know what "normal" looks like, and this summer isn't it. Still, it's pretty on par for a normal Oklahoma summer. Which is something to celebrate considering six months ago, all anybody wanted to talk about was how brutal summer was going to be as we enjoyed our 70° February.

Maybe it's all connected. I certainly think so... But maybe it's not. It's just another weird year we can all mark down in our mental calendar.
