Complete Guide for Mushroom Farming In Kenya For the Year 2025

Many people have lately realized what a potential we have in agribusiness in Kenya and have gone into some of the lucrative ventures in the country such as Kienyeji chicken farming, fruit farming and mushroom farming. The latter has specifically attracted many youth especially those in urban settings. There are obvious reasons as you will see in the discussions in this article.

The Mushroom Market in Kenya

Let me give you some facts about mushroom farming in this country that will stir your interest: according to the National Farmers Information Service (NAFIS), our country produces only 500 tons of mushrooms per year yet the demand just within the country is 1200 tons.

Do you know what that means? The consumers of mushrooms in our country have to import at least 700 tons every year. Such a high and undersupplied demand only means one thing: there is huge ready market for mushrooms, making its farming a huge business opportunity as well.

We have actually written on the cost involved in mushroom farming in Kenya and how profitable the venture is in this article: How Profitable is Mushroom Farming in Kenya: Costs and Market Analysis

Mushroom Farming Requires only a small space

Another fact that will excite you about mushroom farming is that you do not need several acres of land to make a good income. In Kenya, some farmers are actually turning their backyards and even garages into   mushroom farms, and confess that they make way more than what they did from their large scale farming of other crops.

But well, it’s not all easy money and overnight success as the foregoing statements might make it sound. To start a solid business in mushroom farming, one needs to invest in a number of things. Let’s take you through these things; we shall be glad to clarify anything that doesn’t come out clearly later. You can always Call Richfarm Kenya or Whatsapp us on 0724698357.

Mushroom Growing House Design and Requirements

So the first investment you need to make is building a mushroom growing house. It’s not really costly: in fact, all you need is a simple mud-house with a grass thatched roof. This can be done the very traditional way of using posts and sticks to build the wall structure then fill it up with mud or you can do it as we did using earthen bricks as shown below.

Once the house is complete, you need to make shelves. We chose to use wood and off-cuts since these are readily available and cheap materials. These shelves are used hold the mushroom growing bags. Now that’s where the science starts- the bags!

You Can Prepare or Buy Ready Mushroom Growing Bags

Mushroom growing bags are simply plastic bags filled with a material called a substrate. The substrate is specially prepared using agricultural remains. Basically, anything grown on land is a potential substrate for mushroom cultivation. One may use rice husks, dry banana leaves or coconut waste. Anything from the legume family, such as bean waste, is great because of the nitrogen content. Most commercial mushroom farmers in Kenya use hay, wheat straw or rice husks. Its preparation process is a bit detailed; I cannot cover it in this article but you can always reach us by email or Whatsapp for help in that.

We have also designed a special course for you that will focus on training you on how to make compost. These trainings will teach you how to reduce your costs in mushroom farming, specialize in the best variety of mushrooms, and take your mushroom farming business to a professional level. These trainings will take place once every month at our mushroom farm in Banana starting March 2025. 

Where To Buy Spawns - The Mushroom Seeds

Next are the spawns, or the mushroom seeds. These seeds can only be bought from a professional propagator so as to be sure you get clean, non-contaminated material. On average, 1 kg of spawn will cost ksh 600 and would be enough for approximately 40 standard size bags. These seeds are introduced in the bags filled with the substrate and all a farmer does from there on is simply maintain the recommended moisture levels in the bags and the growing house, and wait to start harvesting: no weeding, no spraying pesticides and fungicides and no working under a scorching sun!

Wholesale Mushroom Prices in Kenya

Due to the crop’s lower cost of production and the high yielding capacity, mushrooms present a good opportunity for small to middle-scale farmers. A kilo of mushroom retails at between Ksh 400 and Ksh 600. This high profit margin means that you will take a shorter time to break even and eventually make profits.

There are a total of fifteen different cultivated mushrooms varieties in the world. A farmer may need to know the various types in order to make the right decision when investing in this sector. The most common ones in Kenya are button and Oyster mushrooms. There are exotic mushrooms that can be grown, often for medicinal use, but they require more skills to grow and knowledge of the markets to find buyers.

The best mushroom variety to grow in Kenya

Button mushrooms are quite popular and readily available. The downside is that they are prone to diseases and infections. Oyster mushrooms on the other hand, are hardier and more resistant to infections. Besides, substrates for button mushrooms are prepared and cultured a month ahead. For oyster mushrooms, you can pasteurize your substrate today and introduce the spawns the following day.

The mushrooms are best when freshly picked, so most are sold to local consumers. After they are harvested, they are delivered to local chefs, food co-ops, grocery stores and directly to consumers at the local market.

Challenges

One of the things that can eat into your profits is firewood for pasteurization, which is costly. If one fails to pasteurize properly, the fungi develops mould and that’s a loss. The good thing is that you can buy ready bags of professionally prepared substrate, already spawned (the mushroom seeds already sowed) from Richfarm Kenya.

Harvesting and Marketing

Once ready, mushrooms are harvested consistently twice or thrice a week. Mushrooms have a high demand in Kenya but of course, you have to seek this market. That simply involves informing potential buyers, mostly hotels and supermarkets, of your products. You will get very nice orders especially if you can prove to them that you will be a consistent supplier.


We hope you make it big in mushroom farming in Kenya. However, there are a few other interesting farming ventures that can suit you, having only a small scale. These include:

Avocado Farming: How To Get the Highest Yield Per Acre in Kenya

Avocado Farming in Kenya and the Market Outlook

Avocado farming in Kenya, as well as around the globe, is gaining prominence, mostly because of the nutritious benefits of the fruit. The fruit is gaining popularity as a healthy super food and as such, the annual global demand is increasing at a faster rate than the annual global supply. This results in the fruit fetching high prices on the world market. See what Juan Escorcia from Avocados Aguirre says in this article: Demand For Kenyan Avocado Continues to Climb: The Issue Right Now Is Providing a Continuous Supply.

Despite the increase in the prices, the fruit’s demand continues to grow. Kenya has become the 6th largest producer of avocados in the world and as such, there is a great deal of talk and action around avocado farming in Kenya. Even the government is making a lot of efforts to retain our reputation for good quality and sustainable production for both domestic and global market.

Hass avocado Farming in Kajiado, Kenya

Avocado farming is a long-term project that takes 2 years for the trees to come into production. To reap healthy rewards, a farmer needs to adopt specific practices so as to maintain a healthy plantation that yields top production for many years.

Some of the requirements needed so as to get the highest yield in Kenya include;

Cool temperatures

Hass Avocados are generally bigger in cool areas that are in altitudes between 1000m to 2000m, as compared to warm areas. The optimum temperature is 20 to 24 degrees Celsius. Hot, dry weather may cause the Hass Avocado fruit to drop prematurely. Although avocados are fairly resistant to drought, well distributed rainfall of 1000mm - 1200mm is needed for proper crop development. Avocados also hate wind. This is because the trees have very brittle branches that snap off easily. This explains why the highlands of Kiambu, Muranga and Kisii have been considered as the ideal places for hass avocado farming in Kenya.

Irrigation

Hass avocado plants require about 25mm water per week. The main roots are very shallow, thus drip or micro sprinklers are best suited for the plants. The farmers should have enough water all year round; without water, avocado trees can dry up fast. The irrigation water quality should be tested for pH, since high salts, sodium and chloride have a negative effect on the plants. A diligent farmer will invest in soil moisture monitoring system, so as to ensure water is evenly distributed throughout the root area.

Cultivation Requirements

Land preparation

This should be similar to the preparation of land for the other crops. In the case that it’s a newly cleared land, a farmer is advised to plant an annual crop for example, maize, peas or watermelon so as to achieve a good tillage of the cleared land. In the case of strong winds, ensure that there are necessary wind breakers such as hedges are in place.

Planting materials

Avocados can be grown from either seedlings or from the seeds. However, Hass avocados, which are preferred in the export market, are best grown from grafted seedlings. Grafting improves the variety by increasing its resistance to diseases, hence increasing the yield and increases its adaptability to various soils. The seedlings should be inspected by a professional so as to ensure that they are free from diseases. If you want to be sure you are getting high quality grafted hass avocado seedlings, buy them from Richfarm Kenya nurseries.

Planting holes

The standard spacing for grafted hass avocado in Kenya is 5 by 5 meters. With this spacing, 150 avocado trees can be planted in an acre. However, tree spacing within the line can range from 3m to 5m while the space between the lines should be at least 5m and at most 7m. The best practice is to dig the holes in a straight line. This will make tending to the trees and harvesting easy. 

The holes should be at least 2 feet but can be up to 1m deep. Soil samples should be taken when digging the holes, while being careful not to mix the topsoil with the subsoil. Send the samples to a legitimate soil testing center for pH testing.

Planting

The farmer should use two buckets of farmyard manure properly mixed with the topsoil, 250gm of double superphosphate fertilizer, and a certified insecticide to fill the planting holes. Planting should be after the onset rains when the rainwater has properly penetrated the soil. Irrigate the newly planted seedlings until the first shoots appear. Sometimes, the young grafted hass avocado seedlings might need to be tied up with sticks to support them.  

Mulching

A thick organic mulch is recommended in young plants so as to reduce evaporation off the soil and prevent very high and low root temperatures and salinity build up. The mulch also reduces weed competition.

Pruning

Pruning starts at the planting stage when shoots from the rootstock of the grafted seedlings are removed in order to redirect all the growing energy to the top part. It is also done before flowering and upon completion of harvesting. Pruning allows light to penetrate the orchard, improves yield and provides a superior tree structure. We have extensively explained avocado pruning in this article: How to Prune and Train Avocado Trees for Maximum Production

Thinning

This involves removing some of the already formed fruits so as to reduce competition for nutrients. I know it’s a painful thing for a farmer to pluck off fruits that have already formed. However, it is necessary to do so in order to have a number of fruits that can be perfectly supported by the tree to grow to the desired large size.

Pests and Diseases

Prevention is the most efficient and economical method of pest and disease control. These measures include weed control, proper fertilizer application, maintaining optimum plant density and proper selection of planting materials.
