Growing Banana in Nairobi

Soil suitability analysis based on Nairobi's nutrient profile

Banana can be grown in Nairobi County, but the soil scores 45/100 and needs targeted management to reach full potential. Local soils average pH 6.85 — neutral and inside the 5–7 band Banana prefers, so no lime is usually required. 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/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Banana, which favours loam. At current prices (about KES 12/kg) and a typical 7,500 kg/acre yield, a well-managed Banana crop here can gross roughly KES 90,000 per acre.
