Growing Cape Gooseberry in Mombasa
Soil suitability analysis based on Mombasa's nutrient profile
Mombasa County is a challenging environment for Cape Gooseberry (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 6–7.5 band Cape Gooseberry prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing those deficits. Cape Gooseberry prefers loam soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. At 50 m, the county sits below Cape Gooseberry's preferred altitude range (1200–2600 m), which limits yield potential due to heat stress. Cape Gooseberry's full potential is about 5,000 kg/acre (~KES 600,000/acre at KES 120/kg), but at Mombasa's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
