You asked to be on the list. Here is what your tree is doing all winter, and what we are doing when we come.
Every fall, it starts. Somebody calls or texts and says, “Put me on the prune list.”
So we write the name down, and come winter we roll up and prune the tree. Most folks who ask for that know what it means on the surface: we come and cut their trees at a certain time of year.
But there’s a reason it’s that time of year, and it’s a good one. Two things are going on at once every winter, and both of them matter. Here’s what your tree is really doing while it’s on that list. And just as importantly, here’s what we’re doing.
Most people think the first cold snap puts a tree to sleep. The cold helps, but the real alarm clock is the light. As the days get shorter in the fall, the tree reads those shrinking days and starts the shutdown early, while the weather is still mild. A tree that waited for the first freeze to get ready would not make it. Ours start getting ready while we’re still complaining about the heat.
A leaf is a little factory. All summer it makes food for the tree. When the days shorten, the tree does something most of us could learn from: it goes through those leaves and pulls out everything worth keeping, the sugars, the nutrients, and moves it down into the trunk and roots for storage.
That shutdown is exactly why leaves change color. The green drains out as the tree withdraws what it needs, and the yellows and oranges that were hiding underneath the green all summer get their one turn in the spotlight.
Then the tree seals each leaf off where it connects to the twig, and lets it drop. A leaf in winter is a liability. It loses water the tree cannot replace from cold ground, and it catches wind and ice weight the tree does not need. Dropping leaves is not the tree failing. It’s the tree traveling light.
And those falling leaves are the signal. Everybody knows trees lose their leaves in the winter. What most folks don’t know is that the leaves coming down means the tree has gone dormant. Bare limbs are not a tree dying. They’re a tree that has clocked in for its winter work.
All that stored food sits in the roots and the wood as the tree’s winter savings account, and the tree spends that savings on the work it cannot do while it’s busy growing: healing, and getting stronger underground.
On the warm days we get in the middle of a North Texas winter, the part of the tree above ground stays asleep, but the roots quietly keep growing. Winter is root season. And all winter long the tree is sealing over the wounds it took during the year, shoring itself up, and regrouping from everything the year threw at it: the storms that tore at it, the drought that starved it, the heat that cooked it.
Trees hurt too, in their own way. Every wound a tree takes is real, and it carries that wound into winter and spends the season closing it up. A tree in January is not doing nothing. It’s recovering, and building the foundation it will spend next spring growing on top of.
A dormant tree is alive on a budget. It breathes slowly, it sips instead of drinks, and it does not need much from you. But “not much” is not “nothing.” It is always good to water your trees before a hard freeze. It gives those roots a little more security: wet ground holds the day’s warmth and lets go of it slow through the night, so roots in watered soil don’t freeze up as easily as roots sitting in dry dirt. A good layer of mulch over the roots works like a blanket, evening out the temperature swings our Texas winters are famous for.
What it does not need is fertilizer in late fall to “help it along.” Feeding a tree that is trying to go to sleep is like handing coffee to a man at bedtime. It can push out soft new growth that the first freeze burns right off.
Our live oaks play by different rules. A live oak is semi-evergreen: it holds its leaves through winter and swaps them out in the spring, dropping the old ones as the new ones come in. So if your live oak is dropping leaves in March, that’s the normal spring exchange. If it’s dropping them in November, that is not dormancy, and it’s worth a look.
True evergreens like cedars keep their foliage and just slow way down. Different trees, different winter plans. The ones that drop everything in the fall are not sicker than the ones that don’t. They’re running a different strategy.
This is why your name goes on a list for winter and not for June.
A dormant tree has its energy stored safely below ground, so pruning takes the least out of it, and it seals those cuts when spring growth starts. With the leaves gone, we can see what we’re doing: the whole structure of the tree is right there in front of us, the crossing limbs and the deadwood plain as day.
And because every cut is a wound the tree has to carry, we’re careful about every one of them: where it goes, how it’s made, and whether it needs to happen at all. A cut made right is one the tree can close. A cut made careless is one it wears for years.
In oak country, timing is also about disease. The fungus that causes oak wilt spreads with help from sap beetles, and fresh cuts draw them in. Here those beetles are most active from roughly February through June, so the safe stretch for oak work is the heart of winter, before February. That’s one more reason your name goes on the list now. More on that in our oak wilt guide.
So when we come out in January, both sides of that list are working. Your tree is spending the winter healing and building roots. We’re spending it making the careful cuts it can close in the spring.
Come spring, the days stretch back out, the ground warms, and the tree spends its savings. Buds swell, and everything it stored all winter pours into new leaves, new growth, and for a lot of our trees, flowers and acorns. A healthy tree comes out of dormancy like it means it.
That’s what the prune list actually means. If you’re on it, we’ll see you while your tree’s asleep. If you’re not on it and you’ve got a tree that needs work, winter is the season for it. Call or text us at (972) 430-8330 and we’ll write your name down too.
And if you’re standing there looking at a bare tree wondering whether it’s asleep or gone, we wrote a whole piece on how to tell the difference, scratch test and all: Is Your Tree Dead, or Just Playing Dead?
Winter is the season for the big work. Do a tree check with Annie, or have us come out and take a look. Estimates are always free.
