Take the Cuttings Before the Frost Does

Coleus, impatiens, begonia, geranium and the sweet potato vine will all die at the first frost, and all of them will root from a four-inch cutting in a jar or a pot on the windowsill. Which ones root in water, which want soil, how long each takes, and what to do when the jar goes cloudy.

The Ground Is Still in August: Why Fall Planting Works

The air turned cool this week. Six inches down, the soil is still running weeks behind it, and roots keep growing in that warmth long after the leaves are gone. That lag is the whole secret of fall planting, and it tells you exactly what to put in now and what to leave for spring.

How to Collect and Sow Milkweed This Fall

The pods splitting along the roadside this month are the easiest wildflower you will ever plant, and fall is the only season that works without a refrigerator. Which pods to pick, how to get the silk off in thirty seconds, where the seed goes, why you never bury it, and the one milkweed not to plant in the South.

The acorns hitting the driveway this month are the cheapest tree you will ever plant, and the next four weeks are the only time of year to do it.

Spring Is Planted in the Fall

Tulips and daffodils will not bloom without months of real cold first. The chill is the ingredient, not the obstacle. Here is why the ugliest purchase at the garden center is the best trade of the year, and how to plant it so it pays out in April.

When the Asters Open, the Last Diner of the Year Is Serving

Nearly everything else in the yard has bloomed and gone to seed. What is still flying in September will run almost entirely on two flowers. Here is the six week clock on the season's last nectar, and why the scruffy corner deserves a stay of execution.

A potted garden chrysanthemum crowned with tight green buds on porch steps at dusk.

Aug 24, 2026

The mantis on your porch dies at the first hard frost, and everything she leaves behind is a tan foam case the size of a walnut, glued to a stem. What it is, how to find it when you cut the beds down, and the one mistake that fills a kitchen with a hundred mantises in February.

Sep 7, 2026

What the Chickadee at Your Feeder Does All Winter

It does not fly south and it does not freeze. Starting this month the chickadee hides thousands of seeds, grows a bigger brain to find them, and spends every winter night alone in a tree hole with its body turned down twenty degrees. The whole winter of the smallest bird on the feeder.

A single coyote standing at the dewy edge of a suburban lawn at first light, looking back over its shoulder toward a treeline

Sep 6, 2026

The Pack You Heard Last Night Was Four Coyotes

September is the month the coyotes start singing behind the field, and it always sounds like twenty of them. It is usually a family of four, sometimes two. Why your ear doubles the count, what the biggest urban coyote study ever done found in their diet, and the one honest rule for the cat.

The Box Turtle in Your Garden May Be Older Than Your House

Box turtles live past a hundred and almost never leave a patch a few hundred yards across, so the one eating your fallen tomatoes has likely been there for decades. The kindest thing most people do for one, carrying it somewhere safer, is the thing that kills it. What to do instead, this fall and on the road.

A groundhog at the mouth of its burrow beneath the corner of a weathered garden shed in low golden light

The Groundhog Under Your Shed Is About to Vanish

By late October the groundhog that has been flattening your beans will seal itself into a chamber below the frost line and slow its heart to five beats a minute.

The Mosquito Trap in Your Basement Corner Has Eight Legs

Aug 29, 2026

Do the Bees Really Go Home Before Rain? The Old Sign, Tested

Beekeepers have sworn by it for centuries: when the foragers quit the flowers early, weather is coming. Modern hive research says they are right, and the reason is stranger and better than the folklore. Here is how to run the check from your own goldenrod patch.

Leaves Do Not Fall. The Tree Cuts Them Off.

Aug 26, 2026

The Worm in Your Parsley Is a Butterfly

The Goldenrod Is Innocent

Every August the showiest flower in the ditch gets blamed for allergy season, while the real culprit blooms green and invisible ten feet away. The case falls apart the moment you look at how pollen actually travels.

An American crow perched on a weathered fence post beside ripening sweet corn at golden hour.

Aug 24, 2026

Aug 18, 2026

Aug 18, 2026

Why Swallows Fly Low Before Rain

The old rhyme about low-flying swallows is one of the few weather proverbs physics grades out almost perfectly. The birds are not reading the sky. They are following their groceries.

Two mature maples side by side at the edge of a lawn in low evening light, the nearer one turned orange-red on one whole side while the rest of its canopy and the tree beside it are still summer green

Sep 16, 2026

The Tree That Turned Early

A field note from the back lawn. One of the two maples went orange on its west side in the first week of September while its twin stayed green, and the tree was not announcing the season. It was announcing a root. What I found at the base in the morning, which early colours are normal and which are a flag, and the three things to look for where the trunk meets the ground.

Sep 15, 2026

The Pumpkin Vine Plants Itself as It Goes, and That Is Why the Borer Did Not Kill It

Lift a pumpkin vine tonight and look under the leaf joints. At every joint that lay on damp soil there is a tuft of white roots, a second root system the plant grew for itself on its way across the bed. What those roots are for, which squash grow them and which cannot, how they save a plant the vine borer has hollowed out, and the one time in the season it is safe to move a vine.

Put the Mower Back Up to Three

Pull the Mulch Off the Trunk

A field note from a walk down my own street. Every young tree had a cone of mulch piled against its bark, and it took me one evening on my knees to undo what the crew did in May.

Sep 12, 2026

Stop Deadheading the Roses in September

Sep 10, 2026

The Black Spots on Your Maple Leaves, and the Two Other Marks Worth Knowing

Every September the maples on the street come out in black spots and somebody calls a tree company. Tar spot, anthracnose, and scorch are the three marks a maple leaf carries this month, and only one of them is a message. Here is how to read them from the sidewalk.

What Killed That Patch of Lawn? Grubs, Drought, or the Dog

Every September lawn has a brown patch and a worried owner. Three tests you can run on your knees in two minutes tell grubs from a dry spell from the dog, and two of the three need no bag of anything at all.

Aug 29, 2026

The Cheapest Soil Test You Own Is Blooming Right Now

One apple hanging on its stem among leaves, turned so that its sun-facing side is deep red and its shaded back is clearly green, with more apples and an old ladder soft in the background

Sep 16, 2026

Why the Apple Is Red on One Side and Green on the Other

Turn an apple on its stem and the back of it is often a different colour from the front. The red is not sent up from the leaves and it is not a sign of ripeness. It is made in the skin, on the spot, and only where light lands. How the skin does it, why a green apple cannot, what the orchards in Japan do with paper bags, what cold nights add, and the one thing red never tells you about an apple.

A glass jar of freshly cut basil stems on a weathered wooden kitchen counter by a window in low warm evening light, kitchen scissors beside the jar and a dark garden soft in the window behind

Sep 15, 2026

Bring the Basil In Before Fifty

A field note from the kitchen step. Basil is the one plant in the garden that dies of cold weeks before anything freezes, and the night it happens is the night the forecast says forty eight. What I found on the step the morning I did not listen, why the tomatoes next to it never noticed, and the two ways to keep the last of it.

Four ears of fresh sweet corn on a weathered wooden kitchen counter by a sunny window, two in pale green husks and two shucked to show pale yellow kernels

Sep 13, 2026

Cure the Squash Before You Store It

A field note from the porch bench. A butternut off the vine is not finished, and the ten warm days you give it now are the difference between soup in March and a soft spot by Thanksgiving.

A wooden bowl heaped with ripe red and orange garden tomatoes, stems up, on a farmhouse counter in low September sun

Sep 12, 2026

Never Put a Tomato in the Fridge

A ripe tomato keeps making its own flavor until you eat it, and cold switches that off. Here is what the study measured, which notes go first, the one exception, and what to do with a September counter full of them.

The Green on a Potato Is a Warning

A gardener's stained hands pulling a spent tomato vine off a stake in low golden light with a wheelbarrow of vines behind

Sep 4, 2026

What to Do with Tomato Vines When the Season Ends

The vines come out in the next few weeks, and what you do with them decides how much blight you plant next spring. Here is the order to pull them in, what goes in the compost and what goes in the bag, why your hands come out yellow, and how to get the stain off.

A hand pulling a frost dusted orange carrot from dark garden soil in low golden light

Sep 3, 2026

Leave the Carrots in the Ground

Every Squash Flower Lives One Morning. Spend Ten Seconds of It Wisely

A squash blossom opens at first light and closes for good by early afternoon, pollinated or not. When a plant covered in flowers hands you nothing but yellowing stubs, the morning shift is being missed. Here is how to tell the male flowers from the females, and the ten second hand pollination that fixes an empty vine.
