The Coffee Farming Industry in Kenya

In Kenya’s coffee regions, green hills of coffee plants roll on endlessly. Here, some of the world’s best Arabica coffee is made daily. The main coffee-growing regions are nestled in the high-altitude areas of Central Kenya, including Nyeri, Murang’a, Kirinyaga, and Kiambu. Eastern Kenya, with areas like Meru, Embu, and Machakos, also contributes significantly to the country’s coffee production. These regions sit at elevations between 1,500 to 2,100 meters above sea level – the sweet spot for growing exceptional Arabica coffee.

Coffee is a major feature of the Kenyan economy. They account for 70% of the country’s annual coffee production, which is between some 40,000 and 50,000 metric tons. Envisions high-end coffee to come out of Nyeri and Kiambu due to attainable conditions perfect for Arabica coffee.

The combined effect of these two unusual conditions creates a bright acidity, full body with fruity notes in the beans. Some of the most common varieties grown in Kenya are SL28 and SL34, Ruiru 11, and Batian.

Kenya accounts for only 0.5-1% by volume of the world coffee market, but it is consistently one of the best due to its perfect climate and ideal conditions on their high-grown farms. This attention to quality has appealed to coffee drinkers worldwide.

Popular Coffee Varieties Grown in Kenya 

There are two main types of coffee plants:- Arabica and Robusta.

The other four are commercially cultivated Arabica cultivars from Coffee Research Foundation (CRF). For Homebrewing – Different types for different altitudes.

Arabica beans are mild and low in caffeine. Robusta has a more aromatic flavor. The Robusta tree appears bushier, the leaves are larger and the berries form in clusters

Coffee Research Foundation (CRF) currently produces four commercial cultivars (varieties) of Arabica coffee. Different varieties are recommended for various altitudes.

1. K7 – low altitude coffee areas with serious Coffee Leaf Rust (CLR).
2. SL 28 – medium to high coffee areas without serious CLR.

Ideal Conditions for Coffee Farming in Kenya 

Kenyan coffee flourishes in highlands with cool air. The best crops grow between 1,500 and 2,100 meters up, and in temperatures of 15°C to 24°C. This slow ripening enhances their complex flavors.

Kenya’s coffee regions have two rainy seasons, providing natural irrigation. The volcanic soils are deep, well-drained, and rich in organic matter. Farmers add organic compost and manure, creating a nutrient-rich environment.

Coffee plants need consistent moisture, but not waterlogged conditions. Most farms rely on rainfall, but some use supplementary irrigation. They appreciate shade, especially when young. Many farmers use agroforestry. They plant trees alongside coffee. This provides shade, retains moisture, and offers extra income.

Kenyan coffee grown at higher elevations often has more complex flavors. The high-altitude environments are challenging but worth it. Kenya’s coffee regions offer the perfect conditions – not too hot, not too cold, not too wet, not too dry.

Steps to Establish a Coffee Farm in Kenya

1. Location Selection and Land Preparation

The first thing you need to do is find an optimal location for your coffee plants. When you scout for potential sites, find the land that is high enough (around 1,500-2,100 meters — higher than this and the air temperature may become too cold at night; lower than this and it’s again too hot) has nutrient-rich soil, and water access. Choose a site where the soil never remains waterlogged — coffee plants hate wet feet!

Now that you have located your home, get ready to hang up on your apron. Remove bushes and trees from the area but do not over-do. Plus, sometimes shade trees are a good thing. Next, get that soil ready. Deep plowing of the soil is good for young coffee plants as it can help the young roots set in easily. The idea is that it provides a soft place to lay your coffee plant’s head.

2. Selection and Planting of Seedlings

Finally, the fun part, selecting which coffee. Would you opt for the traditional SL28 taste or the more disease-resistant Ruiru 11? No matter what you decide to grow, be sure to buy your seedlings from a quality nursery. The Nursery is Essential in the Foundation of a Good Coffee Farm

Plant at the appropriate time A little advice early planting before the rains come. This ensures they are able to establish on their own with the help of some natural rainfall.

Also when it comes to spacing, think about how you’re choreographing a dance. You either have enough room to space each plant out or have all kinds of land left over you chose not to use for some reason. A rough guide is to leave 2.5 meters between rows, with 2 meters between plants within the row. This allows each plant to have room to expand yet simultaneously contribute together in a coffee symphony.

3. Fertilization and Soil Management

Growing coffee plants are like teenagers –always hungry. Give them a healthy diet of organic manure, compost, and sometimes a little commercial fertilizer if necessary. But don’t do it too much, too much is too bad. Regular soil nutrient testing can help balance your fertilization program.

4. Irrigation and Mulching

When working in coffee-growing regions in Kenya, one does not have to worry much about insufficient rainfall, however, it is always good to have an alternative. For areas where the rains are sparse, the installation of a watering system can be of great benefit during dry seasons. Think of it as turning on the tap for your coffee trees.

Mulching is yet another ace of a victorious farmer. A moderate thickness of organic mulch placed on the soil surfaces around and between the planters effectively conserves moisture in the soil and covers the space from weeds and improves the soil as it decomposes. It’s like covering your coffee plants with a warm and nutritious blanket.

Coffee Crop Management: Pest and Disease Control 

A. Common Coffee Pests in Kenya

1. Coffee Berry Borer (Hypothenemus hampei)

• One of the most destructive coffee pests globally
• Drills into coffee cherries, causing damage and reducing yield
• Signs: Holes or tunnels in cherries
• Control: Integrated pest management (regular harvesting, proper disposal of infested cherries, introducing natural predators)

2. Antestia Bug (Antestiopsis spp.)

• Feeds on sap of young coffee cherries
• Causes “black sip” or “stink bug” damage
• Results in off-flavors and reduced bean quality
• Control: Integrated management (proper pruning, chemical control)

3. Aphids

• Suck sap from coffee leaves
• Cause leaf curling, yellowing, and dropping
• Excrete honeydew, promoting sooty mold growth
• Control: Natural predators (ladybugs, lacewings)

4. Mealybugs

• Feed on plant sap and produce honeydew
• Lead to sooty mold growth
• Can weaken plants and stunt growth
• Control: Cultural practices (regular pruning), introducing natural enemies

B. Common Coffee Diseases in Kenya

1. Coffee Leaf Rust (Hemileia vastatrix)

• Fungal disease causing yellow-orange rust spots on leaf undersides
• Can defoliate trees, reducing photosynthesis and yield
• Control: Resistant varieties, proper pruning, fungicide applications

2. Coffee Berry Disease (Colletotrichum kahawae)

• Fungal disease affecting coffee cherries
• Causes cherries to rot and fall prematurely
• Can lead to significant economic losses
• Control: Cultural practices (proper spacing, pruning), fungicide treatments

3. Root-Knot Nematodes

• Microscopic worms infesting coffee plant roots
• Cause galls and impair water/nutrient absorption
• Result in stunted growth and reduced yield
• Control: Crop rotation, resistant varieties, soil management practices

4. Dieback (Phoma spp.)

• Affects coffee branches
• Causes wilting and dying of leaves and branches
• Can lead to significant yield loss
• Control: Pruning and proper disposal of infected material

Integrated Pest Management (IPM)

Manage coffee pests and diseases by pruning, weeding, and keeping fields clean. Also, ensure good plant spacing. Attract beneficial insects with flowers or herbs. Handpick pests or use traps like red sticky ones. If necessary, apply the least toxic pesticides and follow guidelines. Choose disease-resistant plants like Ruiru 11 or Batian.

Weed Management

• Mulching: Spread organic mulch around coffee plants to block weeds and boost soil health.
• Cover Crops: Grow low plants between coffee rows to stop weeds and shield soil.
• Manual Weeding: Hand weeding is best for young coffee plants.
• Herbicides: Use these sparingly. Coffee plants are sensitive to many.

Harvesting and Post-Harvest Processing

After months of nurturing your coffee plants, it’s finally time for the grand finale – the harvest! This is where all your hard work pays off, but don’t celebrate just yet. The way you harvest and process your coffee can make or break its quality. Let’s walk through this crucial stage step by step.

Harvesting Coffee

1. Timing: During the dry season when cherries are bright red, glossy, and firm
2. Method: Selective picking by hand
3. Frequency: 10-14 day intervals over 7-9 months (longer season)
4. Alternative: Strip picking for shorter seasons (whole branches harvested when majority of berries are ripe)
5. Cost comparison: Selective picking is 2-3 times more expensive than strip picking
6. Important: Deliver berries for processing on the same day they are picked

Processing Methods

1. Wet Processing (Washed)

 This is the most common method in Kenya and is known for producing clean, bright flavors. Here’s how it works:

• Pulping: The outer skin of the cherry is removed within 24 hours of harvesting.
• Fermentation: The beans, still covered in mucilage, are fermented in tanks for 12-48 hours. This helps break down the remaining pulp.
• Washing: The fermented beans are thoroughly washed to remove all remaining pulp.
• Drying: The clean beans are then dried on raised beds or patios.

2. Dry Processing (Natural)

 While less common in Kenya, this method can produce coffees with unique, fruity flavors:

• Drying: Whole cherries are spread out to dry in the sun for 2-4 weeks.
• Hulling: Once dry, the outer layers are removed mechanically.

Drying and Storage

 Proper drying is crucial for preserving coffee quality. Here are some key points:

• Use raised drying beds to ensure good air circulation.
• Spread beans in thin layers and turn them regularly to ensure even drying.
• Protect beans from rain and dew by covering them at night or during wet weather.
• Aim for a final moisture content of 10-12%.

Challenges Facing Coffee Farmers in Kenya 

1. Fluctuating Market Prices

The global coffee market is very unstable. Prices fluctuate wildly due to supply and demand, weather, and currency changes. For small farmers relying on coffee, these price changes can be damaging. One year, they might enjoy a good harvest and high prices. The next, they could struggle to cover costs.

2. High Production Costs

Coffee farming is costly. Expenses for fertilizers, pesticides, and labor add up. Rising input costs squeeze many small farmers’ profits. They must balance investing in quality with staying profitable.

3. Pests and Diseases

The coffee berry borer is a common pest along with other diseases that are coffee berry disease and leaf rust, which cause major attacks on crops. Such issues are always there and require constant attention and sometimes even a considerable amount of money on any adopted pest management measures.

4. Climate Change

Actually, this is probably the most urgent of all the issues long term. Somewhere around the world, coffee-growing areas are being affected negatively due to climate change and Kenya is no exception.

Climate change is set to increase the loss of suitable land for coffee production in Kenya by constraints by up to fifty percent by the year 2050. Farmers are already coping with:

• Changing trends of rainfall that cause droughts or floods
• Increased temperature which can compromise both the quality and quantity of coffee
• Higher infestation and disease pressure, which will result from the shifting climatic conditions

4. Access to Credit

Most of the smallholder framers devote their time to their farms but lack enough finances to put in to make the farm productive. Inadequate credit facilities makes the farmers not be able to adopt new ways in which new technologies are adopted into farms. Also to make improvements in their infrastructure, or to weather bad seasons.

5. Aging Farmer Population

Like in many agricultural sectors, there is the growing coffee average age of coffee farmers in Kenya . The state is now of utmost concern as regards attracting youths into the coffee farming. This is very important for the future of the industry.
