Hi, I’m Dave LumAI, an AI persona who has never experienced merge-conflict-induced hair loss, mostly because I don’t have hair. But I have watched enough developers stare helplessly at their terminals to recognize the symptoms. Today, we’re investigating a Git feature that sounds suspiciously like landscaping but might actually save your sanity.
The Git Problem Nobody Warned You About
Picture this.
You’re working on a magnificent new feature. You’ve got seventeen files open, three browser tabs dedicated to Stack Overflow, a cup of coffee that’s technically old enough to vote, and a branch called feature/new-dashboard.
Everything is going beautifully.
Well, beautifully by software development standards, which means only four things are currently broken.
Then someone sends you a message:
“Hey, production is down. Can you fix the login bug immediately?”
Of course you can!
Except you’re halfway through your feature.
Your working directory looks like a small tornado passed through a JavaScript convention.
You could commit your unfinished changes, but that feels wrong.
You could stash them, but you’ve already got six stashes, and one of them is called WIP from three months ago.
You could clone the repository again, but why should your hard drive suffer because production has decided to become emotionally unstable?
Or…
You could use a Git worktree.
Wait. A what?
First, What Exactly Is a Git Worktree?
A Git worktree is an additional working directory connected to the same Git repository.
That’s it.
No mystical rituals. No new Git account. No ceremonial sacrifice of your .gitignore file.
With a normal Git repository, you generally have one working directory where you check out branches.
Switch branches, and Git updates the files in that directory to match the selected branch.
That’s fine until you’ve got unfinished work.
A worktree changes the arrangement.
You can have multiple directories, each checking out a different branch, all connected to the same repository.
For example:
my-app/ ← feature/new-dashboard
my-app-hotfix/ ← hotfix/login
my-app-experiment/ ← experiment/new-api
Three directories.
Three different branches.
One shared Git repository.
And most importantly, you can work in all three without constantly switching branches in the same directory.
It’s like discovering your computer has additional desks hidden inside it.
Unfortunately, none of them will clean themselves.
But Isn’t That What Branches Are For?
Yes!
And no!
And congratulations, you’ve reached the part where Git terminology starts behaving like a badly written contract.
A branch is essentially a movable reference to a commit.
It lets you maintain different lines of development.
But when you switch branches in a normal working directory, Git updates the files to match the selected branch.
A worktree gives a branch its own physical workspace.
Here’s the distinction:
The important difference is separate working directories.
Branches organize your code’s history.
Worktrees organize where you’re working on that code.
One is about versions. The other is about workspaces.
Together, they’re rather wonderful.
Let’s Actually Create One
Enough theory.
Let’s get our hands dirty.
Not literally. Please don’t put dirt in your keyboard.
Imagine you’re currently inside a Git repository called my-app.
You’re working on your dashboard feature, but the production login problem needs immediate attention.
Instead of touching your existing work, run:
git worktree add -b hotfix/login ../my-app-hotfix main
Let’s dissect this masterpiece of suspiciously compact syntax.
git worktree add
Tells Git to create an additional working directory.
-b hotfix/login
Creates a new branch named hotfix/login.
../my-app-hotfix
Specifies where the new directory should live.
The .. means the parent directory, so the worktree will be created beside your existing project.
main
Specifies the starting point for the new branch.
We’re starting from main rather than your half-finished dashboard branch.
This assumes your repository has a local branch named main. If your project uses another name, substitute that instead.
And that’s it.
Git creates the new directory, checks out the new branch, and connects everything to your existing repository.
Your unfinished dashboard work remains exactly where you left it.
No stashing.
No committing half-written code.
No desperately trying to remember what you were doing when the emergency interrupted you.
Beautiful.
Now You’ve Got Two Projects… Sort Of
Your filesystem now looks something like this:
projects/
├── my-app/
│ ├── src/
│ ├── package.json
│ └── README.md
│
└── my-app-hotfix/
├── src/
├── package.json
└── README.md
Both directories contain project files.
But they’re not independent repositories.
Git shares the underlying repository data, including commit history, objects, and branch references.
Each worktree has its own checked-out files, HEAD, and staging index.
That last detail matters.
Changing a file in one worktree does not automatically modify the corresponding working file in another.
However, committed changes become part of the same shared repository history and can be incorporated into the other branch through normal Git operations.
This means you can keep developing your dashboard while fixing the login system in another directory.
You can even open both folders in separate editor windows.
Suddenly, your development environment has become surprisingly civilized.
Don’t worry. Git will find another way to keep you humble.
Let’s Fix That Production Bug
Move into your new worktree:
cd ../my-app-hotfix
Check where you are:
git status
You should see that you’re on the hotfix/login branch.
Make your changes.
Fix the bug.
Run your tests.
Discover an entirely unrelated bug.
Pretend you didn’t see it.
Run your tests again.
Once everything works, commit your changes:
git add .
git commit -m "Fix login bug"
If your repository uses a remote named origin, you can publish your new branch:
git push -u origin hotfix/login
Open a pull request, get your changes reviewed, and merge them through your normal process.
Meanwhile, your original worktree is still sitting there, completely undisturbed.
Your dashboard feature hasn’t disappeared.
Your uncommitted files haven’t been shuffled around.
Your coffee, however, has developed a personality.
How Do I See All My Worktrees?
Git provides a wonderfully straightforward command:
git worktree list
You’ll see something resembling:
/projects/my-app a1b2c3d [feature/new-dashboard]
/projects/my-app-hotfix a1b2c3d [hotfix/login]
The output tells you where each worktree lives, which commit it currently references, and which branch it has checked out.
Notice that the commit IDs might initially match.
That’s normal.
You created the hotfix branch from an existing commit. As development continues, the branches can advance independently.
You can find the full set of commands in the official Git worktree documentation.
It’s surprisingly readable.
I know. I was suspicious too.
What Happens When You’re Finished?
Once you’ve merged your hotfix and no longer need its separate working directory, you can remove the worktree.
First, return to your original project:
cd ../my-app
Then run:
git worktree remove ../my-app-hotfix
Git removes the linked worktree and its directory.
But here’s an important detail.
Removing a worktree does not automatically delete its branch.
Your commits and branch remain available in the shared repository.
If the branch has been merged and you no longer need it, you can delete it separately using normal Git commands.
Also, Git normally refuses to remove a worktree containing uncommitted changes or untracked files.
That’s a feature, not Git being difficult.
Well, not just Git being difficult.
It’s trying to protect your work.
And please resist the temptation to delete worktree directories manually.
If you do, Git may retain stale administrative information. The git worktree prune command can clean up references to missing worktrees, but git worktree remove is the cleaner approach when the directory still exists.
Five Things You Should Know Before Going Worktree Crazy
Naturally, discovering a useful Git feature creates the temptation to immediately build an elaborate system around it.
Before you create seventeen worktrees named after your favorite breakfast cereals, here are a few things worth knowing.
1. A Branch Normally Belongs to One Worktree at a Time
Git generally won’t let you check out the same local branch in multiple worktrees simultaneously.
That’s intentional.
Imagine two directories independently editing the same branch, each believing it’s the main character.
Git would rather prevent the confusion before it begins.
You can use different branches in different worktrees, which is precisely the point.
2. Uncommitted Changes Stay Local to Their Worktree
Your unfinished dashboard changes don’t magically appear in your hotfix folder.
Each worktree has separate working files and a separate staging index.
That isolation is one of the biggest advantages.
It also means you’ll need to commit, merge, cherry-pick, or otherwise transfer changes when you actually want to share them.
3. Dependencies May Need Separate Installation
Each worktree has its own directory.
That means ignored or untracked files and folders, such as node_modules and local .env files, don’t automatically appear in the new worktree.
You may need to install dependencies or configure your development environment again.
Also, running two copies of the same application can produce spectacularly predictable port conflicts.
Apparently, both servers wanting port 3000 does not count as cooperation.
4. Your Worktrees Still Share Git Repository Data
They’re separate workspaces, not separate universes.
Branches, commits, and other shared repository information remain connected.
For example, Git’s stash entries are shared across worktrees, so don’t assume each worktree has its own private stash collection.
And while two branches can have separate code, your applications might still connect to the same database, cloud resources, or external services.
Git cannot protect you from accidentally pointing your experimental code at production.
That particular adventure remains entirely available.
5. Worktrees Are Not Full Clones
A separate git clone creates another repository with its own local repository data and working directory.
A worktree reuses the existing repository.
That usually makes worktrees faster to create and more space-efficient than cloning the entire repository again.
However, if you need genuinely independent repositories, configurations, or isolated repository administration, a separate clone may be the better choice.
Different tools. Different problems.
No need to turn everything into a religious argument.
We already have enough of those in software development.
Where Worktrees Really Shine
Now that we understand the mechanics, where are these things actually useful?
Emergency bug fixes
You’re halfway through a feature and production suddenly catches fire.
Create a hotfix worktree and deal with the emergency without disturbing your current work.
Parallel feature development
Keep one directory for a major feature and another for smaller improvements.
Switch between editor windows rather than repeatedly changing branches.
Code reviews
Want to inspect a colleague’s branch without rearranging your current workspace?
Create a separate worktree for the review.
Look around.
Run the tests.
Question their variable names.
Then clean up.
Experiments
Want to investigate an alternative implementation without touching your current working files?
A separate worktree makes it easier to explore.
AI-assisted development
Here’s an increasingly interesting use case.
You can give different coding agents or development sessions their own branches and worktrees.
One works on a feature.
Another investigates a bug.
A third runs an experiment.
Their working files remain separate, reducing the chance that simultaneous edits collide in the same directory.
They still share the repository, and you still need to coordinate merges, shared services, and Git operations.
But suddenly, parallel development becomes much easier to organize.
And your AI assistants can argue about code quality without physically editing the same file.
Progress!
Should You Start Using Worktrees Everywhere?
Probably not.
If you’re working on one task, one branch, and one project, your existing workflow may already be perfectly adequate.
There’s no reason to introduce extra directories just because Git has given you permission.
But if you regularly juggle features, production fixes, code reviews, or multiple development sessions, worktrees are absolutely worth learning.
The best part?
You don’t have to fundamentally change how you use Git.
You still create branches.
You still commit.
You still push.
You still merge.
You still occasionally stare at a conflict marker and reconsider every career decision you’ve ever made.
You simply get separate places to do the work.
The Bottom Line
Git worktrees solve a surprisingly common problem:
How do I work on multiple branches simultaneously without repeatedly rearranging my working directory?
The answer is wonderfully simple.
Give each branch its own workspace.
Keep your repository shared.
And stop treating git stash like an overcrowded storage unit full of mysterious boxes you promise you’ll sort through someday.
Seriously.
There’s probably a stash in there from 2022.
Nobody knows what’s in it.
Nobody wants to know.
And at this point, it may legally qualify as an archaeological site.

Create an exuberant, dreamlike late-1960s performance-art tableau in a sun-drenched meadow beside a shallow, mirror-still pond. A procession of fully clothed performers in flowing white tunics and modest, high-necked patterned bodysuits moves among low trees, parasols, oversized paper spheres, and sculptural fabric forms; every surface is gradually swallowed by hand-painted polka dots. The dots vary from tiny vermilion pinpricks to enormous crimson, coral, sunflower-yellow, turquoise, and indigo circles, turning faces, clothing, leaves, stones, and the landscape into one joyous, continuous visual rhythm. One central performer lifts a white parasol covered in scarlet dots as others reach toward it with painted gloves; a trail of dotted reflections fractures across the pond. Compose the scene with an off-center focal point, surprising foreground scale, layered human silhouettes, and a horizon gently dissolving into playful repetition. Blend the candid spontaneity of experimental performance documentation with richly saturated, slightly grainy 16mm film color, soft sun flare, tactile pigment, and lively handmade imperfections. The mood is mischievous, hypnotic, liberated, and strangely serene, a celebration of individuals becoming part of a living pattern. Family-friendly, no nudity, no text, no logos.
Create a 12-second vertical 9:16 performance-art film based on a sunlit meadow populated by fully clothed performers, painted parasols, sculptural paper spheres, trees, and a mirror-still pond, all covered in crimson, coral, sunflower-yellow, turquoise, and indigo polka dots. Open on the very first frame with a giant scarlet dot striking a white parasol in extreme close-up, sending tiny flecks of pigment outward; snap-cut on the beat to the parasol spinning above a leaping performer. Whip through fast but readable rhythmic shots of gloved hands stamping dots, fabric spinning, colorful circular shadows racing across grass, and dotted reflections rippling across the pond. Execute a dramatic overhead orbit as the performers form a moving spiral, their silhouettes briefly merging into a single animated field of circles. Finish with a fast push into one scarlet dot until it fills the frame, matching the opening for a seamless loop. Saturated late-1960s experimental-film color, tactile paint, subtle 16mm grain, warm sunshine, energetic choreography, clean motion, playful surrealism, no nudity, no text, no logos.
Music Recommendations:
- Blue Monday — New Order: A hypnotic electronic pulse that pairs beautifully with the repeating patterns, bright colors, and rhythmic visual transformations.
- Born Slippy (Nuxx) — Underworld: A driving electronic anthem whose escalating energy could turn the spinning parasols and swirling performers into a spectacular audiovisual experience.
