Growing Passion Fruit in Nairobi

Soil suitability analysis based on Nairobi's nutrient profile

Quick answer

Yes — Nairobi is well suited to Passion Fruit. Nairobi's soil (pH 6.85, near-neutral) gives Passion Fruit a suitability score of 89/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.

Nairobi County is well suited to Passion Fruit, scoring 89/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 5.5–7.5 band Passion Fruit 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 Passion Fruit, which favours loam. On ShambaIQ's soil-match model, Passion Fruit is the #34 soil match of the 106 crops we assess for Nairobi County. At current prices (about KES 70/kg) and a typical 8,000 kg/acre yield, a well-managed Passion Fruit crop here can gross roughly KES 560,000 per acre.
