Decomposition Day

An experiential day in the forest to let go, decompose what needs to end, and grow what’s next from the parts.

what do we create next?
what needs to rot first?

Join us for a learning club Saturday social! Together we will learn from fungi, nature’s hero decomposers, how to design through decomposition.

For many of us, endings feel like failure, and letting go feels like loss. For others, endings feel like something happening to us: collapse arriving at speed while we brace for uncertain futures. Both come from the same disconnection: we've never learned to end things well.

Decomposition Day is an invitation to practise endings differently: not as failure, waste or collapse, but as the oldest method we have for returning value to ourselves, our work, and the living world we're part of.

What to expect: You’ll spend the day in a learning club with good people. Go slow in nature, take a beat and re-orient. ​Meet mycelium in the woods. Embody a decomposer mushroom in meditation. Let something go in a rot ritual. Mushroom snacks and birthday cake! (p.s. we’ve also got 8 Sporesight totes that need new homes; first come first served at checkout).

We’ll learn a new method: Rot to Regenerate → Design through Decomposition. Play with mycelium materials, decompose something extractive and ask: what remains, what rots? 

You’ll acquire sporesight: the capacity to see what needs to rot, let it go well and grow what regenerates from the parts.

Who is this for? Anyone feeling the limits of business-as-usual. Designers, strategists, futurists, solarpunks, sustainability leads, creatives, educators, world-builders, recovering corporate wizards. You share an intuition that the dominant model of growth is doing harm. You've got something you know needs to end, and you're ready for some fresh fun(gi) thinking.

You’ll ease away with: Rot, reframed as transformation. A method to practise on Monday. A booklet, stickers and carabiner. A connection to others doing this work. And a mycelial gift to compost in your home 🍄‍🟫

Come and get your mushroom eyes on with us.

Yours in spores,

Jess, Sporesight Foundress

why now?

We’re obsessed with creating; terrible at ending. In 2025 we crossed seven out of nine planetary boundaries. In 2026 Earth Overshoot Day landed in July; the rest of this year we're borrowing from our futures. The same growth-at-all-costs logic is stripping our time: highly productive, always behind, time-starved for someone else’s gain.

We all know this. And yet we keep making more.

In nature, death isn't the end of life; it's part of a regenerative cycle. Transitions work the same way: the new can't grow until the old composts. So rather than asking what to create next, let's ask what needs to rot first.

Call it de-growth; call it getting your mushroom eyes on. Once you see, you can't unsee.

  • Giulia Romano, Field Notes

    “I loved Decomposition Day! Spending a day in the forest reflecting on what fungi can teach us about sustainable growth - and about letting go of the things that no longer serve us - was engaging, inspiring, thought-provoking and fun.”

  • Natasha Compagnone, PA Consulting

    “This was a refreshing and provocative new way of thinking, which is exactly what our team needed!”

  • İlayda Bakare, Exhibits App

    “Before learning about decomposition I assumed infinite resources, especially with AI. Now I ask: ‘What are we retiring to free up capacity?’ This mindset changed how I approach everything in my work.”

  • Christian Leake, System

    “I found Sporesight’s workshop genuinely fruitful. After decomposing inherited assumptions, what seemed ossified became fluid and alive. I'd love to apply the strength of the process to other industries!”

  • Michael Kibedi, First & Fifteenth

    “Before, I held onto half-finished ideas in my own practice. After learning to decompose what wasn't working, I released them. Now I'm intentional about work I take on, and far less guilty admitting when something has ended.”

  • Caitlin Keeley, RADAR

    “I loved the materials, design, altar, vibe that you conjured. As someone who believes in a mycelial model of change, it was cool to see you invoke our mushroom mentors to reflect on a very relevant topic. Mushrooms! Endlessly inspiring!”

All you need to know…

  • Yes! If the extractive status quo is wearing you down and you want a way to let go, with a group of folks ready to rot. If you're curious about regenerative futures and don't know where to start. If you've got something that needs to end.

    No fungi knowledge required. Just an open mind, and something you're willing to let go of.

  • Highgate Woods is within reach of central London. Exact location details and travel advice will be shared on signup.

  • Light picnic lunch. Notebook, pen, camera, walking shoes, waterproofs. Something you’re willing to let go of (a habit, process, mindset or thing). No laptops.

  • The location is a natural landscape and requires walking.

    Please let us know if you are joining and have any accessibility needs. We will be doing group work, with the option for solo and to find your own space at any time.

    In future we would like to host wheelchair accessible Decomposition Days dependent on interest. If this is you, let us know! Email hello@sporesight.co

  • Absolutely! Every team and business is unique. Let us know what you need, and we'll work with you to shape a plan that fits your goals and budget.

  • Sure, we can issue a refund if cancelled at least 72 hours in advance.

  • Ticket sales help us cover costs: the venue, materials, prep, time and all the work that has gone into developing this methodology.

    Sporesight is a social enterprise. What’s left after costs goes back into the mission.

    That being said, we get it - times are tough! If money is the only thing standing between you and the day, please reach out to discuss potential options for reduced pricing.

    Yours in spores.
