Growing Mint in Nairobi

Soil suitability analysis based on Nairobi's nutrient profile

Quick answer

Yes — Nairobi is well suited to Mint. Nairobi's soil (pH 6.85, near-neutral) gives Mint a suitability score of 92/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.

Nairobi County is well suited to Mint, scoring 92/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 6–7.5 band Mint 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/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Mint, which favours loam. On ShambaIQ's soil-match model, Mint is the #12 soil match of the 106 crops we assess for Nairobi County. At current prices (about KES 100/kg) and a typical 4,000 kg/acre yield, a well-managed Mint crop here can gross roughly KES 400,000 per acre.

Bags per acre in Nairobi
0.50.3

Nairobi's nitrogen (1.1 g/kg) is 92% of the 1.2 g/kg Mint needs, so the standard 0.3 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
