Why Percy

Your garden is more than what you grow.

It’s the first tomato of summer. The flower that finally opened. The hummingbird that stopped a few feet from your face, then left.

Most of that never makes it into a garden journal, because you were busy being out there. Percy was made for all of it.

What it is

Just talk.

Tell Percy about your garden like you’d tell a friend: the plantings, the harvests, the questions and all the moments you want to hold onto. It turns it all into a gorgeous living record of your season.

Migration Report
Arrives January 2027

A keepsake of your whole season: your garden’s year in review.

At the end of the season, Percy writes your Migration Report. Your garden as you’ve never seen it. A whole year of weather in a single ring. Every plant you grew on one page, each with its own chapter in your own words. The visitors, the highlights, and the small moments that would have faded. Laid side by side, you finally see how your season fit together.

Yours to keep

Every report comes with a digital edition.

Your whole season as a digital edition you download and keep. It’s the story of your season, written from every note you made, in your own words, with your own photos.

The cover of the digital edition on an iPad: the year’s weather ring above Marigold Cottage, A Season in the Garden, 2026. — The cover

The digital edition open on an iPad at the start of June in the journal: the month’s temperature strip, then each day’s notes and photos, from hanging petunias to the pea harvest. — The journal

The weather spread on an iPad: every day’s high and low across the year, the rain hanging below, and the last and first frost marked as soft bands. — The year in weather

The herbarium opens on an iPad: Tomatoes, with all twelve varieties grown and a year stripe showing when to sow and harvest next season, facing Lettuce, You never really stopped sowing lettuce. — Every tomato you grew

More from the herbarium on an iPad: peaches, potatoes, beets, cherry trees, parsley and tulips, each with an illustration, a quote from the gardener’s notes and next season’s marks for sowing, pruning, blooms and harvest. — The herbarium

Garden visitors on an iPad: a spread titled Who your garden made room for, with illustrations of hummingbirds, a rabbit, monarchs, fireflies, a black swallowtail and a praying mantis beside the gardener’s own notes. — The garden’s visitors

And soon, in print

Your season, on the shelf and on the wall.

A hardcover book of your year, and fine-art prints of your weather and the plants you grew. Made from your own garden, and coming with the Migration Report.

Sold separately, not part of a Percy membership. US only for now. The book needs a season with 35 notes or more, the stem print 8 notes, and the herbarium print 12 plants.

The printed book open on a potting bench by a window, late sun across June in the journal.

The book open on an old writing desk on a winter morning, at the weather spread: every day’s high and low, and every drop of rain.

The book open on a kitchen table beside coffee and toast, at the herbarium: Tomatoes facing Kale.

The weather map print, framed on a wall.

You don't do anything to make this happen. Every time you share a note, Percy is building a coffee table book about your garden, and your first Migration Report is part of your free season. Then it becomes your plan for next year: the varieties worth growing again, and the ones we shall never speak of again.

Garden journal
The Nest

A garden diary that writes itself.

The Nest is your garden’s living memory. Every note you share finds its place: the plantings and the harvests, and all the moments in between. Remembering your garden should feel as beautiful as being in it.

Brian's Nest in October. 376 notes so far.

The best moments open the story.

Highlights from your season live at the top: important garden updates, wildlife sightings, family moments. The ones worth a full-page spread.

Each plant gets its own chapter.

Every note, every photo, the whole arc from seed to harvest (or seed to a series of increasingly concerned observations, also a valid arc). It assembles itself.

Field Notes for everything in between.

The questions you've asked, IDs you requested, and anything more curious than decisive. Like the notes in the margin of your season's story.

Garden planner
Twigs

A garden planner that remembers what you want to do next.

Tending

Tending holds your gardening to-dos. Just hold the button and say “I need to transplant the seedlings this weekend” or “Remind me to water the garden every 3 days.” Percy will remember it for you and nudge you on your home screen.

Someday

Someday is the place to save your garden inspiration. It's a private shelf for the maybe-one-day ideas: the plant you spotted on a dog walk, the new bed you're dreaming up, the varietals you want to try next year.

One garden’s season

Not just what you planted, what you lived.

Stewardship

Gardens are bigger than gardens.

You plant zinnias for the color, and then the bees find them. The more you notice in your garden, the more you see what depends on it. Percy knows what’s native or invasive where you garden, tells the friends from the foes, and suggests organic options first.

Garden advice

The garden advisor you've always wanted.

Everything you tell Percy becomes knowledge about your garden. So when you ask for advice, the answer comes from your actual garden. And Percy doesn’t wait to be asked. It gives you a heads-up before a frost or a dry week, and suggestions based on your own garden.

You ask

What's eating my collard greens?
Is this a weed or a wildflower?
Which tomato did best for me this summer?
What should I plant where the beans were?
What can I plant to bring in more butterflies?

Organic first. When something's eating your collards, Percy starts with the gentlest fix that works, tells you when the culprit is actually a friend, and knows which plants are native or invasive where you garden.

Percy keeps an eye out

A weather heads-up on the Perch in the Percy app, October 19 in the first frost window: A hard freeze tomorrow night. Bring in the pots. Water what's in the ground, then cover it. Wet soil holds warmth. And disconnect the hoses. With an illustration of a frozen garden spigot and a coiled hose. — The Perch, the day before a hard freeze.

A heads-up when it matters.

Open Percy and it shows you one thing worth knowing today: frost tonight, a task that's due, or a check-in on the peas you planted two weeks ago. Every page comes from your garden, your weather and your list.

From a Garden Letter. Your weather: the first light frost usually comes around October 18, so decide what to harvest and what to cover; kale doesn't need it. Your wildlife: rake leaves into the beds as winter cover for frogs, toads and beneficial insects. You captured: three of Brian's own notes from that week, quoted word for word. — From Brian's Garden Letter, mid-October.

Your garden sends you letters.

Every couple of weeks, the Garden Letter arrives by email with your weather, how your garden can help local wildlife right now, the moments you captured in your own words, and what's on your list.

From a gardener

“I've been using Percy for a few weeks and I love it. It personalizes answers based on what I've told it about my garden, and it's literally like having a little garden expert in my pocket.”Haley L. · Goldsboro, NC

Who it's for

Percy is for gardeners who'd rather be gardening.

If you've tried garden apps

and found yourself maintaining the app instead of the garden, Percy is not that. There are no forms, Gantt charts or dashboards. You just talk about your garden, then put the phone away. So you can stay present instead of staring at a screen.

If you keep a paper journal,

you already know the value of writing things down. Percy gives you a garden memory that writes itself, talks back, and gets more extraordinary every season. Everything you love about journaling, plus the part where it actually does something with what you've told it. Plus, zero risk of paper cuts. Until the hardcover arrives.

If you don't track anything currently,

Percy shows you what it feels like when nothing is lost. And if you're new to gardening, you don't need to know what to track: just talk about what you see.

You don't need to use it every day. There are no streaks to keep or garden points to earn. Percy won't nag or guilt-trip you. Just share something when it feels notable: when you plant something, notice a problem, or harvest something that made you unreasonably happy.

Percy works beautifully if all you ever do is talk to it. But if you really want to geek out, you can tell it your location, your soil type, your garden layout, and Percy gets even more specific to your garden.

What is Percy?

Percy is the garden journal that remembers, so you can enjoy your garden. You talk to it about what you plant, notice, and plan, and it turns that into a complete record of your garden, then into knowledge: answering your questions, connecting what happened from one season to the next, and giving advice based on your own garden's history. You never have to log anything by hand.

Is there an app that remembers what I planted?

Yes. That’s the whole idea behind Percy. Say “I put the Sungolds in along the south fence,” and Percy remembers what you planted, where, and when, with that day’s weather. Months later, ask “When did I plant the Sungolds?” and it just knows.

Can I get my garden journal printed as a book?

Soon. Your Migration Report will come with the option to order it as a hardcover book: the year’s weather, pages for the plants you talked about most, and your journal month by month, in your own words and photos. There are fine-art prints for the wall, too. They’re printed to order and sold separately, not included in a Percy membership. US only for now, and the book needs a season with 35 notes or more, the stem print 8 notes and the herbarium print 12 plants.

How is Percy different from other garden journal apps?

Most garden journal apps are logs: you fill in forms, and you get a record you can search later. Percy keeps the same detail, but you just say it, and then it does something a log can't: it turns your record into knowledge. It connects what happened across seasons, spots patterns you'd miss, answers questions from your own garden's history, and comes to you with advice when it matters. A log tells you what happened. Percy helps you understand what it means for next season. And at the end of every season, it writes your Migration Report: your garden’s year in review.

Is Percy a garden diary app?

Yes. Garden journal, garden diary: same idea (in the UK and Australia it’s usually called a diary). Percy is a garden diary that writes itself, and in the US, UK, Canada and Australia it knows which plants are native or invasive where you garden.

Is Percy a garden planner?

Yes. Tell Percy what you need to do and when, and Tending remembers it and nudges you on your home screen. Someday holds the plants and ideas you're saving for later.

Can Percy identify plants, pests, and diseases?

Yes. Show it a photo and Percy tells you what it is, whether it's native or invasive where you garden, and what to do about it. Then it remembers the ID.

Does Percy recommend organic methods?

Yes. Percy suggests organic options first, recognizes beneficial insects before you spray them, and in the US, UK, Canada and Australia tells you whether a plant is native or invasive where you garden. Our stewardship

Is Percy good for beginners?

Yes. There's nothing to set up and nothing to learn: you just talk to it. Percy is the easiest way to start, and because its advice comes from your own garden, it gets more useful the longer you use it.

How much does Percy cost?

It's free to start, with no credit card required. After your free season, it's US$39 a year. Percy has native apps on iPhone and Android, and works in any browser on desktop.

Your garden has always had a story. Percy remembers it.
