Growing Tea in Nairobi
Soil suitability analysis based on Nairobi's nutrient profile
Possible but challenging — Nairobi is only marginally suited to Tea. Nairobi's soil (pH 6.85, near-neutral) gives Tea a suitability score of 43/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.
Nairobi County is a challenging environment for Tea (soil-match score 43/100) and will need significant amendment before planting. At an average pH of 6.85 the soil sits above Tea's preferred 4.5–6 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 1.1 g/kg, P 22.1 mg/kg, K 236 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Tea, which favours clay. On ShambaIQ's soil-match model, Tea is the #100 soil match of the 106 crops we assess for Nairobi County. Tea's full potential is about 2,200 kg/acre (~KES 55,000/acre at KES 25/kg), but at Nairobi's 43/100 suitability a realistic target here is closer to 1,183 kg/acre (~KES 29,575/acre) unless the constraints above are addressed.
Better matched to Nairobi's soil: Dhania, Pumpkin, and Rosemary — each scores higher on the same soil.

Top dressing guide
Nairobi's nitrogen (1.1 g/kg) is 92% of the 1.2 g/kg Tea needs, so the standard 1 bag/acre is raised to 1.25. Split it across two applications to limit leaching.
