Azolla is a fast-growing water fern that is changing the way Kenyan farmers feed their livestock. With its rich protein content and fast growth rate, Azolla is one of the cheapest and most sustainable feeds for animals like poultry, cattle, pigs and even fish.
It also works well as organic fertiliser. Many farmers across Kenya are now turning to Azolla farming to cut feed costs and boost productivity.
If you are looking for a simple and affordable feed option, Azolla farming in Kenya might be the solution you need.

Why Azolla Farming In Kenya Is Gaining Popularity
Azolla farming is not only cost-effective but also easy to start. It does not require large pieces of land or expensive inputs. Farmers can grow it in ponds, ditches or even containers at home. Once introduced, Azolla multiplies quickly and can be harvested every few days.
This makes it ideal for farmers seeking a reliable and continuous feed source. Beyond its use as animal feed, Azolla also improves soil fertility when used as compost. These multiple benefits make Azolla a valuable addition to any farming system in Kenya.
Common Varieties Of Azolla You Can Grow
There are several types of Azolla, but not all are suited for the Kenyan climate. The main varieties include:
Azolla Nilotica – Common in wet regions of Africa
Azolla Imbricata – Known for its thick growth pattern
Azolla Pinnata – Most common and widely grown in Kenya
Among these, Azolla Pinnata is the best variety for local farmers. It grows fast and adapts well to different environments, making it a top choice.
Nutritional Value That Makes Azolla A Super Feed
Azolla is rich in nutrients that make it perfect for livestock consumption:
High protein levels – Up to 25–30% protein, great for animal growth
Essential amino acids – Boost animal immunity and productivity
Vitamins A and B12 – Improve animal health and performance
Minerals – Contains calcium, magnesium, phosphorus and potassium
Rich in fiber – Supports digestion, especially in ruminants
With these nutrients, Azolla supports faster growth and better health in livestock, reducing dependence on commercial feeds.
Conditions You Need For Azolla To Thrive
Azolla requires a moist and shaded environment to grow well. Here is what you need:
Growing space – Ponds, containers, old tanks or any wet ground
Water source – Still or slow-moving water is ideal
pH levels – Grows in pH range of 3.5 to 10; best growth at 4.3 to 7
Temperature – Ideal range is 20°C to 30°C
Light – Needs 25% to 50% sunlight exposure
Manure – Use fully composted manure in the pond to boost growth
Spacing – Ensure at least two feet of space for holding the manure
With these simple requirements, Azolla can produce up to 12 tonnes per hectare under proper care.
Step-by-Step Guide To Starting Azolla Farming
Starting your Azolla farm is easy. Here’s how to go about it:
Select a site – Choose a place with partial shade and still water
Prepare the pond – Use plastic sheets, cement tanks, or old containers
Add composted manure – Spread a layer to feed the growing Azolla
Introduce Azolla culture – Spread a small amount on the water surface
Control weeds and pests – Keep the area clean to avoid contamination
Monitor regularly – Maintain pH and water levels to support healthy growth
Azolla grows fast and spreads across the water surface in just a few days.
How To Harvest Azolla And Use It
Azolla is ready for harvesting every three days once it has fully covered the pond surface. You can harvest it in two main ways:
Feed fresh – Scoop and feed directly to livestock
Dry and store – Dry it in the sun and store for future use
Drying is recommended when you have excess harvest. Since Azolla spoils quickly, drying extends its shelf life and prevents wastage.
Ways To Use Azolla On The Farm
Azolla is highly versatile and can be used in several ways:
Livestock feed – Cattle, goats, pigs, poultry and fish benefit from it
Fertiliser – When decomposed, Azolla adds nitrogen and organic matter to the soil
Compost booster – Mix with other organic materials to speed up composting
Its ability to improve both animal health and soil fertility makes it a dual-purpose crop worth investing in.
Azolla farming in Kenya offers a smart solution to the high cost of livestock feed. It is easy to grow, fast to harvest and rich in essential nutrients.
Whether you are running a small farm or a large livestock operation, adding Azolla can improve your productivity and reduce costs. Get started with simple tools and enjoy the many benefits of this super plant.
