Today I topped up my homemade liquid fertiliser using banana trunks and peels — a simple, earthy ritual that feels like returning nutrients to their natural cycle. The steps were straightforward:
- Chopped banana trunks and peels — freshly cut and added to the blue barrel.
- Rainwater base
— nothing fancy, just clean rainwater from the farm tap to moisten and
activate the mix.
- Fermentation
— the mixture will sit and slowly break down, releasing its goodness over
time.
Each layer of banana matter adds
texture and life to the brew — fibrous trunks, soft peels, and the occasional
green fruit remnants.
The Benefits
This humble liquid fertiliser is a
powerhouse of natural nutrients:
- Potassium boost
— bananas are rich in potassium, which strengthens plant stems and
improves fruit quality.
- Phosphorus and calcium — essential for root development and flowering.
- Microbial activity
— the fermentation process encourages beneficial microbes that enhance
soil health.
- Moisture retention
— banana trunks contain natural fibres that help retain water in the soil.
- Eco-friendly recycling — turning farm waste into nourishment reduces
dependency on chemical fertilisers.
Over time, the liquid becomes a mild,
nutrient-rich tonic that can be diluted and applied to vegetables, fruit trees,
and ornamental plants alike.
There’s something deeply satisfying
about watching waste transform into life-giving nourishment. The scent, the
texture, and the slow bubbling of decomposition remind me that farming is both
science and poetry — a rhythm of renewal.
Step-by-step banana liquid
fertiliser recipe
Step
1: Gather Materials
Banana trunks and peels — freshly chopped pieces from harvested plants.
Rainwater — collected naturally or from my farm tap.
A large barrel or container — preferably with a lid to keep insects out.
Optional: a small amount of molasses
or brown sugar to speed up fermentation.
Step
2: Prepare the Base
- Fill the barrel about halfway with rainwater.
- Add the chopped banana trunks and peels.
- Stir gently to mix — this helps oxygenate the water and
start microbial activity.
Step
3: Fermentation
- Cover the barrel loosely to allow gases to escape.
- Let it sit for 2–3 weeks in a shaded area.
- Stir every few days to keep the mixture active and
prevent foul odours.
- You’ll notice bubbles and a mild earthy smell — signs
of healthy decomposition.
Step
4: Application
Strain the liquid before use.
Dilute 1 part fertiliser to 5
parts water for general watering.
Apply directly to soil around plants
or as a foliar spray for leafy crops.
This simple brew transforms farm waste into a living
nutrient cycle — a perfect example of permaculture
in action. It’s low-cost, sustainable, and deeply
connected to the rhythm of my land.

自制香蕉液体肥料
今天我为自制液体肥料进行了补充,加入了香蕉树干和香蕉皮。整个过程简单自然:
- 切碎香蕉树干与香蕉皮 — 新鲜切段后放入蓝色桶中。
- 雨水为基底 — 使用农场收集的雨水作为天然溶液。
- 发酵 — 让混合物静置发酵,缓慢释放养分。
每一层香蕉材料都在分解中释放出生命的能量,形成天然的养分循环。
这种自制香蕉液体肥料富含天然养分:
- 钾元素 — 强化茎干,提升果实品质。
- 磷与钙 — 促进根系生长与开花。
- 微生物活性 — 发酵过程产生有益菌群,改善土壤健康。
- 保湿纤维 — 香蕉树干的天然纤维有助于保持土壤湿度。
- 环保循环 — 将农场废料转化为养分,减少化肥依赖。
发酵后的液体肥料可稀释后使用,适合蔬菜、水果树及观赏植物。
看着废料转化为滋养生命的肥料,是一种深刻的满足。那股泥土的气息与缓慢的发酵声,提醒我农业不仅是科学,更是一种诗意的循环
