Why Don't We Use Fertilizers? A Different Way of Growing Tea
When people visit our tea fields, one of the questions we hear most often is:
"Why don't you use fertilizer?"
It's a reasonable question.
Most tea farms—whether conventional or organic—use fertilizer to support healthy growth and maintain stable harvests.
So why would anyone choose not to?
At Kenichi Shizen Nouen, we grow tea without pesticides or fertilizers.
Not because we believe fertilizer is inherently bad.
But because we believe tea trees are capable of growing without it.
In this article, we'll explain why most tea farms use fertilizer, what happens when you stop using it, and why we have chosen a different approach.
Do Tea Plants Need Fertilizer?
The simple answer is:
No.
Tea plants (Camellia sinensis) can grow without fertilizer.
Like many perennial plants, they naturally develop root systems that search for water and nutrients in the soil.
However, growing and producing are two different things.
Without fertilizer, tea trees generally grow much more slowly.
They produce fewer new shoots, harvests become smaller, and in some years there may be very little suitable for picking.
The trees survive.
They simply grow at their own pace.
Why Do Most Tea Farms Use Fertilizer?
There are many good reasons.
Every time tea leaves are harvested, nutrients leave the field as well.
To maintain healthy plants and stable production, many farmers return nutrients to the soil through fertilizers.
Organic tea farms do the same, except they use approved organic fertilizers rather than synthetic chemical fertilizers.
This approach helps produce consistent harvests year after year and supports the practical realities of commercial tea farming.
There is nothing unusual about this.
It is simply a different way of growing tea.
Why We Chose a Different Path
At Kenichi Shizen Nouen, our goal is not to produce the largest possible harvest.
Instead, we want to understand how tea trees grow when they are allowed to follow their natural rhythm.
Without fertilizer, the trees grow more slowly.
Some years they produce only a small harvest.
Occasionally, nature decides that they need another season before producing leaves worth picking.
Rather than asking the trees to adapt to our schedule, we adapt ourselves to theirs.
We see this slower growth not as a weakness, but as the tea tree's natural pace.
What We Have Observed in Our Tea Fields
After growing tea without fertilizer for many years, we have noticed changes that go beyond harvest size.
One of the biggest differences is underground.
Deeper Roots
In our tea gardens, we have observed that tea trees grown without fertilizer tend to develop deeper root systems.
Instead of relying on nutrients near the soil surface, the roots appear to grow further into the ground in search of water and nourishment.
This is one of the clearest differences we notice compared with tea fields where fertilizer is regularly applied.
Slower, Softer New Shoots
The spring shoots look different as well.
In many fertilized tea fields, young shoots emerge quickly with a rich green color.
In our tea gardens, they grow more slowly.
The new leaves often appear with a soft yellow-green color before gradually becoming darker as they mature.
To some people, these leaves may look less vigorous.
To us, they simply reflect the natural rhythm of the tea tree.
A Different Tea Garden
The difference is not limited to the tea trees.
Wild grasses grow between the rows.
Many kinds of insects live in the fields.
Birds visit throughout the seasons, and wild animals occasionally pass through.
Rather than managing only tea plants, we care for an ecosystem where many forms of life can coexist.
This is simply what our tea gardens have become over time.
What We Have Learned
We do not believe every tea farm should stop using fertilizer.
Every farm has different goals, different climates, and different challenges.
Our choice is simply one possible approach.
For us, tea farming is not about encouraging the fastest possible growth.
It is about allowing the tea tree to grow as naturally as it can.
We believe that when we respect the pace of the tea tree, we also begin to respect the landscape that supports it.
Conclusion
Fertilizer has an important role in modern agriculture, including organic farming.
Our decision not to use it is not about rejecting other methods.
It is simply the path we have chosen.
By allowing tea trees to grow at their own pace, we hope to produce tea that reflects not only the plant itself, but also the soil, climate, and living ecosystem that surround it.
For us, growing tea is not about changing nature.
It is about learning from it.
