Winter Mode.
Why bulbs need cold: the invisible architecture of growth
Have you ever wondered why bulbs need cold weather?
It’s not the typical question you wake up with, but if you share a mild obsession with gardening, your curiosity eventually runs that deep. We tend to view winter as a season of "nothingness," but the biology of a garden tells a much more provocative story about how we actually grow.
The science of vernalisation: why cold is activation
I recently dove into the botanical research behind this, and what I found surprised me. In the world of horticulture, the cold isn't a pause; it’s a process called vernalisation.
According to botanical science, the cold is an essential activation trigger. Each species has an internal clock, and winter is when the real work begins—cellular reprogramming at a biochemical level we’ll never witness. All that invisible architecture is being built in the dark, in the cold, beneath frozen ground.
We only see the epilogue: the bloom. But the magic—the actual transformation—happened in the unseen months. In "winter mode."
The "Spectacle" trap in business and life.
I think about this more than I should. We’ve trained ourselves to measure growth only by what is visible:
The promotion at work.
The KPIs in our businesses.
The breakthrough moments we can post on social media.
We’ve made spectacle synonymous with progress. But what if the most critical development happens precisely when nothing appears to be happening? When you feel stuck, frozen, or "buried" in conditions that seem designed to break you rather than build you?
Recognising your season.
We all have our seasons. The challenging part isn’t enduring them—it’s recognising which one we’re actually in.
If you are currently in a "winter" phase of your life or career, ask yourself:
Am I stalled, or am I deepening?
Is this a lack of progress, or is it "cellular reprogramming"?
What invisible architecture am I building right now that will support my future bloom?
The difference isn’t always obvious from the inside. When you’re under the frozen ground, it just feels cold.
Learning from the winter gardens.
Maybe we need to see ourselves the way we’d observe a garden in winter. With patience for the intelligence of timing, with trust in processes we can’t track, and with reverence for the invisible work that precedes every bloom.
The stuff we don't see may be the most important part. Like the bulbs.
