Growing Passion Fruit in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Kwale County is a challenging environment for Passion Fruit (soil-match score 2/100) and will need significant amendment before planting. Local soils average pH 6.76 — neutral and inside the 5.5–7.5 band Passion Fruit prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Passion Fruit, which favours loam. At 200 m, the county sits below Passion Fruit's preferred altitude range (1200–2500 m), which limits yield potential due to heat stress. At current prices (about KES 70/kg) and a typical 4,500 kg/acre yield, a well-managed Passion Fruit crop here can gross roughly KES 315,000 per acre.
