It requires a moderate climate with consistent temperatures between 24°C and 30°C for optimal bulb development, although cooler temperatures of 12-24°C are preferred during the early vegetative stages. The crop is sensitive to excess moisture and humidity; therefore, it thrives in areas with low rainfall, often supplemented by irrigation during dry spells. Garlic farming in Kenya flourishes in areas with low humidity, low sunshine, moderate rainfall, and consistent temperatures throughout the year. Best Regions for Garlic Farming in Kenya: The following regions are highly suitable for garlic farming in Kenya: These areas offer ideal temperatures ranging from 12°C to 24°C and well-drained, fertile soils that contribute to healthy crop development and reduce disease risks. Rainfall and Water Requirements: Moderate water is essential for healthy garlic development. The crop typically requires between 400 and 600 mm of rainfall over its growing period. However, excessive rainfall can lead to fungal diseases, particularly if water pools around the bulb. In regions with low or unreliable rainfall, drip irrigation becomes crucial for successful garlic farming in Kenya. Chapter 3: Soil Requirements and Land Preparation for Garlic Farming in Kenya: Soil Characteristics: Garlic requires well-drained, fertile loam or black cotton soil rich in organic matter. The ideal soil pH should range between 5.5 and 6.8. It is critical to avoid heavy clay soils, as they restrict the physical enlargement of the bulbs and lead to poor yields. Key soil requirements for garlic farming in Kenya: Soil Testing: Before starting garlic farming in Kenya, conducting a soil test is essential. It reveals the soil’s pH, texture, and nutrient levels, guiding the farmer on necessary amendments. Where necessary, lime can be applied to raise soil pH, while sulfur can help reduce it. Land Preparation Steps: Proper land preparation is the foundation of profitable garlic farming in Kenya: Chapter 4: Choosing the Right Garlic Varieties for Garlic Farming in Kenya: Main Garlic Varieties in Kenya: Three main garlic varieties dominate garlic farming in Kenya: 1. Softneck Varieties: Softneck garlic is the most popular among commercial farmers engaged in garlic farming in Kenya because it is easier to grow and has a longer shelf life of up to six months. 2. Hardneck Varieties: Hardneck varieties produce fewer but larger cloves and are characterized by a woody central stem that produces a false flower stalk known as a scape.While Hardneck garlic is prized for its intense flavor, it does not store as well as Softneck types, making it less ideal for commercial garlic farming in Kenya focused on long-term storage. 3. Elephant Garlic: Elephant garlic is distinguished by its massive size and subtle, mild odor. It has large bulbs and bigger cloves, but the taste and smell are less strong compared to hard and soft neck species. It is less common in mainstream Kenyan markets but commands premium prices where available. Why Softneck Garlic Is Preferred: Softneck garlic remains the preferred choice among Kenyan farmers due to its: Chapter 5: Planting Guide for Garlic Farming in Kenya: Seed

Onion farming in Kenya has emerged as one of the most lucrative agricultural ventures for smallholder and commercial farmers alike. With onions being a staple ingredient in virtually every Kenyan household, hotel, and food processing industry, the demand for quality bulbs remains consistently high throughout the year. Whether you’re a young entrepreneur looking to break into agriculture or an experienced farmer seeking to diversify your crops, onion farming in Kenya offers an incredible opportunity to build wealth from the soil up. The beauty of onion farming in Kenya lies in its relatively moderate capital requirements compared to other agribusiness ventures, combined with strong profit margins that can transform a modest investment into a million-shilling enterprise. In this comprehensive guide, we’ll walk you through everything you need to know about onion farming in Kenya from selecting the right varieties and preparing your land, to managing pests, harvesting, and marketing your produce for maximum returns. Understanding the Onion Market in Kenya: The Growing Demand for Onions in Kenya Onion farming in Kenya benefits from an ever-expanding market. Onions are not just a cooking ingredient; they are an essential component of Kenyan cuisine. From the famous sukuma wiki to rich beef stews, pilau, and chapati accompaniments, onions form the flavor foundation of countless dishes. This universal demand means that onion farming in Kenya enjoys a stable market that rarely experiences prolonged slumps.According to agricultural experts, local onion production in Kenya has improved significantly over the years, supplying a large portion of domestic demand. However, during periods of local shortage, imports from neighboring countries supplement supply, creating opportunities for Kenyan farmers to capture more of this market through strategic timing of their harvest Step 1: Choosing the Best Onion Varieties for Kenya: Your variety choice is the foundation of successful onion farming in Kenya. The wrong variety means small bulbs, disease susceptibility, and poor marketability. The right variety? Bigger bulbs, higher yields, and buyers lining up at your farm gate. Top-Performing Onion Varieties in Kenya: Variety Maturity (Days) Yield (kg/acre) Key Features Best For Red Pinoy F1 90 15,000 Fastest maturing, 6-month shelf life, disease tolerant Quick turnaround, export markets Red Coach F1 110–120 16,000 Deep dark red, stores 5 months, uniform bulbs Premium local & export markets Jambar F1 90–120 10,000 Dark red, easy to cure, greenhouse-compatible All-year production African Red F1 120 18,000 Pink root & purple blotch tolerant, 5-month storage Disease-prone areas Red Creole 150 16,000 Excellent storage, pungent flavor, drought-tolerant Long-term storage, dry areas Bombay Red 120–150 16,000 Globe-shaped, deep purple-red, widely adapted Beginners, diverse climates Texas Grano 120 12,000 White/golden, mild taste, ideal for salads Salad onion market Neptune F1 110–120 15,000 Firm shiny red, pink root resistant, 5–6 month storage High-value markets Hybrid vs. Open-Pollinated: The Cost-Yield Debate: Hybrid F1 varieties like Red Coach and Neptune cost between KSh20,000–KSh50,000 per kg of seed but deliver yields of 15–20tonnes per acre. Open-pollinated varieties like Red Creole cost as little as KSh6,000–KSh25,000 per kg but yield 2–10tonnes per acre. Step 2: Land Preparation: The Make-or-Break Phase: Onions are shallow-rooted. Poor land preparation is the #1 reason farmers fail at onion farming in Kenya. Here’s how to get it right: Soil Requirements: Land Preparation Checklist: Step 3: Nursery Management: Raising Champion Seedlings: Most successful onion farming in Kenya starts in the nursery. Direct seeding in the field leads to poor germination and weak seedlings. Here’s the nursery blueprint: Nursery Bed Setup: Sowing and Care: Transplanting time: 6–8 weeks after sowing, when seedlings are about 15 cm tall. Step 4: Transplanting for Maximum Bulb Size: Transplanting is a delicate operation in onion farming in Kenya. Do it wrong, and you’ll lose 20–30% of your crop to shock. Transplanting Best Practices: The Spacing Secret: Want bigger bulbs? Space plants 10–15 cm apart within rows. Want more plants per acre? Use 8 cm spacing but expect smaller bulbs. Market preference in Kenya favors medium-to-large bulbs, so don’t overcrowd. Step 5: Water Management: The Lifeline of Your Crop: Water can make or break onion farming in Kenya. Onions have shallow root systems and need frequent, light watering not deep flooding. Irrigation Strategies: Growth Stage Water Needs Frequency Establishment (Weeks 1–4) High Every 2–3 days Vegetative growth Moderate-High Every 3–4 days Bulb formation Consistent moisture Every 2–3 days Maturation (2–3 weeks before harvest) Reduce gradually Every 5–7 days Drip Irrigation: The Game Changer for Onion Farming in Kenya: In 2026, drip irrigation is the gold standard for commercial onion farming in Kenya. Here’s why: Investment reality: A drip irrigation system pays for itself within one season through water savings, higher yields, and better bulb quality. For farmers serious about scaling onion farming in Kenya, this is non-negotiable. Step 6: Fertilizer and Nutrition Management: Onions are heavy feeders. Starve them, and you’ll get small, thin-necked bulbs that nobody wants to buy. Fertilizer Program for Onion Farming in Kenya: Application Timing Fertilizer Type Rate/Acres Purpose Basal (at planting) DAP or NPK + manure 50–100 kg DAP Root development Top-dress 1 (3 weeks after transplanting) CAN or Urea 50 kg Leaf growth Top-dress 2 (6 weeks after transplanting) CAN or Urea 50 kg Continued vegetative growth Bulb formation stage Potassium-rich fertilizer As recommended Bulb swelling and firmness Foliar feeding Micronutrients (Boron, Zinc, Magnesium) Every 2 weeks Prevent deficiencies, boost sizing. The Nitrogen Trap: Excessive nitrogen late in the season delays maturity, produces thick necks, and ruins storage life. Stop nitrogen applications once bulbs start forming. Common Nutrient Deficiencies in Onion Farming in Kenya: Apply foliar feeds containing these micronutrients during the bulb-swelling stage for maximum impact. Step 7: Pest and Disease Control: Protecting Your Investment: The warm Kenyan climate that makes onion farming in Kenya possible also favors pests and diseases. Vigilance is your best defense. Major Pests in Onion Farming in Kenya: Pest Damage Control Measures Thrips Silvery streaks on leaves, stunted growth Monitor weekly; apply insecticides when thresholds exceed 5 thrips per plant Onion flies / Cutworms Seedling death, root damage Soil drenches, good nursery sanitation,

Picture this: You’ve invested KES 150,000 into your onion farming in Kenya operation. The seedlings from your nursery looked vibrant. The rains were generous. But one morning, walking through your field in Kajiado or Nyeri, you notice something terrifying bright orange pustules dotting your onion leaves like rust on old iron. Within weeks, your crop weakens, bulbs shrink, and your expected profit of over KES 500,000 evaporates. This is onion rust caused by the fungus Puccinia allii and it’s one of the most underestimated threats to onion farming in Kenya. While Kenyan farmers often worry about purple blotch, downy mildew, and thrips, rust quietly destroys yields from the inside out, reducing bulb size by up to 50% and making crops unmarketable.In this comprehensive guide, we’ll explore everything you need to know about onion rust: its biology, symptoms, lifecycle, and most importantly, how to prevent and manage it within the context of onion farming in Kenya. Whether you’re a smallholder in Kitui or a commercial grower in Nakuru, this guide will arm you with the knowledge to protect your investment. Part 1: Understanding the Enemy:What is Onion Rust? The Fungus Behind the Disease: Onion rust is caused by Puccinia allii, a strictly parasitic fungus that belongs to the order Pucciniales the rust fungi. In onion farming in Kenya, understanding this pathogen’s biology is crucial because it determines when and how the disease strikes.The fungus is an obligate parasite, meaning it can only survive in the presence of living host plants. It attacks species within the genus Allium including onions, garlic, leeks, shallots, and chives. Why Onion Rust Matters for Kenyan Farmers: In the context of onion farming in Kenya, rust is particularly dangerous because: Once rust appears on a farm, continuous cropping of Allium species can lead to serious losses. This is a critical warning for onion farming in Kenya, where short rotations and continuous cropping are common practices. Part 2: Recognizing the Symptoms Early Detection Saves Crops: Early identification is critical in onion farming in Kenya because once rust is established, chemical control becomes necessary, and prevention is always cheaper than cure. Initial Symptoms (Week 1–2): Active Infection (Week 2–4): Advanced Damage (Week 4+) Even a few lesions can reduce marketability in crops like spring onions where the leaves are eaten. For bulb production in onion farming in Kenya, the impact is equally severe—smaller bulbs mean lower prices per kilogram Part 3: Conditions That Favor Onion Rust in Kenya: The Perfect Storm: Climate and Cultural Factors: For onion farming in Kenya, several conditions create ideal environments for rust: 1. Temperature Sweet Spot The fungus thrives between 15°C and 24°C. This means: 2. Humidity and Leaf Wetness: 3. Nutritional Imbalances: Infection is worse on nitrogen-rich soils with low potassium. In onion farming in Kenya, where farmers often over-apply nitrogen to boost growth, this creates a hidden vulnerability. 4. Continuous Cropping Growing onions, garlic, or leeks in the same field year after year builds up inoculum. The fungus overwinters in debris and volunteer plants, making the next season’s crop more vulnerable. 5. Weedy Allium Hosts Wild onion relatives and uncontrolled volunteer plants serve as reservoirs for the fungus, constantly reinfecting commercial fields. Part 4: Integrated Management Strategies for Onion Farming in Kenya: Effective rust management in onion farming in Kenya requires an integrated approach combining cultural, biological, and chemical methods. No single strategy is sufficient. Strategy 1: Cultural Control (The Foundation): Crop Rotation Sanitation Proper Spacing and Ventilation: Irrigation Management: Balanced Fertilization: Resistant Varieties While no fully resistant onion varieties exist, some show partial tolerance. In onion farming in Kenya, consider: Strategy 3: Chemical Control (The Last Resort): When rust appears, fungicides may be necessary. For onion farming in Kenya, the following approaches are used: Protectant Fungicides Critical Application Rules for Onion Farming in Kenya: Strategy 4: Onion Doctor App: Scan your onion plant using the Onion Doctor app to identify the disease correctly and get help from our Agronomist.

Powdery mildew is one of the most destructive yet frequently misunderstood diseases threatening onion farming in Kenya today. Whether you’re a smallholder in Makueni, a commercial grower in Kajiado, or managing a nursery in Meru, understanding this pathogen can mean the difference between a profitable harvest and a devastating loss. At Onion Doctor, we’ve seen firsthand how powdery mildew can quietly destroy entire onion fields across Kenya’s key production regions. This blog is designed to be the most comprehensive, practical, and actionable resource on powdery mildew specifically tailored for onion farming in Kenya. We’ll cover everything from the science behind the pathogen to field-tested management strategies that work in Kenyan conditions. Chapter 1: Understanding Powdery Mildew :The Silent Crop Killer: What Is Powdery Mildew: Powdery mildew in onions is caused by the fungus Leveillula taurica. Unlike the powdery mildew you might see on cucurbits or roses, onion powdery mildew has a unique “internal” or hemi-endophytic lifestyle that makes it particularly tricky to manage in onion farming in Kenya. This pathogen doesn’t just sit on the leaf surface it penetrates the leaf tissue and grows between the cells of the mesophyll, making it harder to reach with surface sprays. This biological characteristic is critical for farmers practicing onion farming in Kenya to understand, as it explains why some treatments fail. Chapter 2: Identifying Powdery Mildew in Your Onion Field: Early Symptoms to Watch For: The first signs of powdery mildew in onion farming in Kenya are easy to miss if you don’t know what to look for. Early detection is your best defense. On the Upper Leaf Surface: On the Lower Leaf Surface: Advanced Symptoms: Why Onion Farming in Kenya Is Particularly Vulnerable: The climate patterns in Kenya create ideal conditions for powdery mildew outbreaks. The pathogen thrives when daytime temperatures reach 26°C with relative humidity around 70-80% conditions common in many onion-growing regions of Kenya, particularly during the transition periods between rainy and dry seasons. The combination of hot, dry days followed by cool, humid nights a pattern frequently experienced in areas like Kajiado and Makueni during certain months is the perfect recipe for powdery mildew epidemics in onion farming in Kenya. Chapter 3: The Disease Cycle:How Powdery Mildew Spreads: Understanding the Pathogen’s Life Cycle: Powdery Mildew pathogen can only survive and reproduce on living plant tissue. This has important implications for management in onion farming in Kenya. Primary Sources: Infection Process: Favorable Conditions for Outbreaks in Onion Farming in Kenya: Factor Optimal Range for Disease Kenyan Context Temperature 10°C to 33°C Common across all onion-growing regions Relative Humidity Below 40% for infection, 70-80% for spread Prevalent during rainy seasons and early mornings Dew on foliage Promotes infection Common in highland areas like Nyeri and Meru Dense plantings Reduces air circulation A common mistake in small-scale onion farming in Kenya Chapter 4: Integrated Disease Management (IDM) for Powdery Mildew: Effective management of powdery mildew in onion farming in Kenya requires an Integrated Disease Management (IDM) approach. No single method is sufficient on its own. Strategy 1: Cultural Practices: Crop Rotation Rotate onions with non-host crops for at least one year. Excellent rotation crops for onion farming in Kenya include: Avoid rotating with solanaceous crops (tomato, pepper, eggplant) as these are also hosts for the pathogen. Field Selection and Preparation: Spacing and Plant Density: Irrigation Management: Nutrient Management: Weed Control: Sanitation: Strategy 2: Resistant Varieties: While specific powdery mildew-resistant onion varieties are still being researched globally, choosing the right variety for your region is crucial. In onion farming in Kenya, popular varieties include: Variety Characteristics Suitability Red Coach F1 High yield, good market color Most popular in Kenya Malbec F1 Disease tolerant, high yielding Good for various regions African Red F1 Early maturing, drought-tolerant Ideal for ASAL regions Neptune F1 High yielding, disease tolerant Suitable for multiple counties Note: While no onion variety is fully resistant to powdery mildew, healthy, vigorous plants from quality seedlings from Onion Doctor are better able to withstand infection. Strategy 4: Chemical Control: When cultural and biological methods are insufficient, chemical fungicides remain an important tool. In commercial onion farming in Kenya, the following active ingredients are effective: Sulfur-Based Fungicides Application Guidelines: Chapter 5: Common Mistakes in Managing Powdery Mildew: Mistake 1: Waiting Too Long to Act: Powdery mildew in onion farming in Kenya can explode from a few spots to a field-wide epidemic in 2-3 weeks. By the time you see heavy sporulation, significant damage has already occurred. Solution: Scout your fields at least twice weekly during high-risk periods. Mistake 2: Relying Only on Chemicals: Spraying fungicides without addressing cultural factors is like treating symptoms without curing the disease. Solution: Implement the full IDM package: cultural, biological, and chemical methods together. Mistake 3: Using Overhead Irrigation: Wetting the foliage creates perfect conditions for powdery mildew and other fungal diseases. Solution: Switch to drip irrigation it’s both water-efficient and disease-preventive. Mistake 4: Planting Too Densely: Many farmers in onion farming in Kenya try to maximize yield by overcrowding, but this backfires by creating a humid microclimate. Solution: Follow recommended spacing (30cm × 8-10cm) religiously. Mistake 5: Ignoring Weeds and Volunteer Crops: Weeds and volunteer onions are silent reservoirs of Powdery Mildew Solution: Maintain clean fields and remove all volunteer plants. Mistake 6: Using the Same Fungicide Repeatedly: This selects for resistant pathogen populations. Solution: Rotate fungicides with different modes of action.

Onion farming in Kenya has grown significantly over the past decade, becoming one of the most profitable horticultural ventures for smallholder and large-scale farmers alike. However, onion farming in Kenya faces numerous challenges, with downy mildew standing out as one of the most destructive diseases threatening yields and profitability. This comprehensive guide is designed to equip every farmer engaged in onion farming in Kenya with the knowledge needed to identify, prevent, and manage this devastating disease effectively. Whether you are a beginner just starting onion farming in Kenya or an experienced grower looking to refine your disease management strategies, understanding downy mildew is critical to your success. In onion farming in Kenya, where climatic conditions in highland regions like Timau, Molo, and parts of the Rift Valley create ideal environments for this pathogen, proactive management is not optional it is essential. What is Downy Mildew? Downy mildew is a fungal-like disease caused by the oomycete Peronospora destructor. Despite being commonly referred to as a fungus, it is actually a water mold that thrives in cool, humid conditions. In onion farming in Kenya, this disease is particularly problematic during the long rains and in irrigated fields where moisture levels remain high.The pathogen attacks the leaves first, destroying the photosynthetic capacity of the plant, and can later infect the bulbs, rendering them unmarketable or causing them to rot in storage. For farmers practicing onion farming in Kenya, where profit margins can be tight and market prices fluctuate, a downy mildew outbreak can mean the difference between a profitable season and total crop loss. Why Downy Mildew Matters for Onion Farming in Kenya: The economic impact of downy mildew in onion farming in Kenya cannot be overstated. Globally, yield losses from uncontrolled downy mildew can range from 30% to 75%, with extreme cases reporting losses of up to 80% in favorable disease conditions. In onion farming in Kenya, where many smallholder farmers rely on onion sales for household income and school fees, such losses are devastating. The disease not only reduces bulb size and quality. In onion farming in Kenya, where post-harvest handling infrastructure is often limited, these secondary infections can destroy an entire harvest during storage.Moreover, onion farming in Kenya is increasingly becoming export-oriented, with Kenyan onions finding markets in Tanzania, Uganda, and the Middle East. Export markets demand high-quality, disease-free bulbs. Downy mildew-infected onions fail to meet these standards, locking farmers out of premium markets. Therefore, mastering downy mildew management is a key competitive advantage in modern onion farming in Kenya. How Downy Mildew Spreads: The Disease Cycle: Understanding the disease cycle is the first step toward effective management in onion farming in Kenya. The pathogen has a complex life cycle with multiple survival strategies: Primary Inoculum Sources: Disease Development: Once conditions are favorable typically when nighttime temperatures range between 4°C and 24°C and relative humidity exceeds 95% the pathogen produces sporangia on infected leaves. These spores are dispersed by wind and splashing rain to neighboring plants. In onion farming in Kenya, the cool, wet conditions of the highlands and the heavy dews common in early morning create perfect conditions for spore production.The disease cycle can complete in as little as 11–15 days, meaning an outbreak can escalate from a few spotted leaves to a field-wide epidemic within two to three weeks. This rapid progression makes early detection and immediate action critical in onion farming in Kenya. Recognizing the Symptoms: Early Detection Saves Crops: Early identification of downy mildew is vital for successful onion farming in Kenya. Farmers should scout their fields at least twice a week, paying close attention to the following symptoms: SYMPTOMS OF DOWNEY MILDEW: CONDITIONS THAT FAVOR DOWNEY MILDEW: EFFECTS OF DOWNEY MILDEW IN ONION: Integrated Disease Management: A Multi-Pronged Approach: There is no single silver bullet for downy mildew in onion farming in Kenya. The most successful farmers use an Integrated Pest Management (IPM) approach combining cultural, biological, and chemical strategies. 1. Cultural Control Practices: Crop Rotation Practice a minimum 3-year rotation away from allium crops (onions, garlic, leeks, chives) and allium-family weeds. In onion farming in Kenya, where land may be limited, this requires careful planning, but it is one of the most effective long-term strategies for reducing soil-borne inoculum. Field Selection and Layout: Spacing and Plant Density: Irrigation Management: Sanitation: Nutrient Management: 2. Use of Certified, Disease-Free Seed and Transplants: Always start with certified, disease-free seed or transplants. In onion farming in Kenya, using quality planting material from reputable suppliers like Onion Doctor is a foundational practice. 3. Biological Control: For organic onion farming in Kenya, biological control options include: Always verify organic certification status with your certifying body before applying any product in organic onion farming in Kenya. 5. Chemical Control: Fungicide Strategies: Fungicides remain the most reliable method for managing downy mildew in conventional onion farming in Kenya. However, improper use leads to resistance, environmental contamination, and residue problems. Follow these principles: Key Principles In onion farming in Kenya, products(mancozeb-based) are commonly recommended for downy mildew control and are best applied between 0–6 weeks after planting. Always consult with a licensed agrovet and read product labels carefully. Conclusion: Securing the Future of Onion Farming in Kenya: Downy mildew is a formidable adversary in onion farming in Kenya, but it is not invincible. Through knowledge, vigilance, and integrated management, Kenyan farmers can protect their crops, secure their incomes, and contribute to the nation’s food security and export earnings.The future of onion farming in Kenya depends on adopting modern, science-based practices while respecting the environment and human health. By combining cultural practices, resistant varieties where available, biological controls, and judicious chemical use, farmers can keep downy mildew at bay and ensure that onion farming in Kenya remains a thriving, profitable industry for generations to come.

Onions are cool-season biennials that are grown as annuals, and they thrive under specific conditions. Temperature: Successful onion farming in Kenya requires temperatures between 15°C and 25°C during the vegetative growth stage. However, bulb formation is triggered by longer daylight hours and slightly warmer temperatures. This is why onion farming in Kenya is most successful during the dry seasons when day-length and temperature conditions are optimal. Rainfall and Altitude: While onions need consistent moisture, excessive rainfall promotes fungal diseases. The best regions for onion farming in Kenya receive moderate, well-distributed rainfall or have access to reliable irrigation. Ideal altitudes range from 0 to 1,900 meters above sea level, which covers most of Kenya’s agricultural land. Soil Requirements: The soil is the engine of onion farming in Kenya. Onions demand well-drained, fertile soils with a pH between 6.0 and 6.8. Sandy loam soils are ideal because they allow for easy bulb expansion and harvesting. Before starting onion farming in Kenya, conduct a soil test to determine pH and nutrient levels. Heavy clay soils should be avoided unless properly amended with organic matter and sand to improve drainage. 4. Step-by-Step Guide to Starting Onion Farming in Kenya: If you are ready to begin onion farming in Kenya, follow this proven roadmap developed by Onion Doctor: Step 1: Land Preparation: Proper land preparation separates amateur attempts from professional onion farming in Kenya. Plough the land to a fine tilth to a depth of at least 20 cm. Remove all weeds, rocks, and debris. Onion roots are shallow and delicate; compacted soil will destroy your dreams of successful onion farming in Kenya. Step 2: Seedbed Preparation (For Nursery): Most successful onion farming in Kenya starts with a nursery. Prepare raised seedbeds about 1 meter wide and apply well-decomposed manure.
