Growing Cape Gooseberry in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Quick answer

Generally not ideal — Kwale is poorly suited to Cape Gooseberry. Kwale's soil (pH 6.76, near-neutral) gives Cape Gooseberry a suitability score of 2/100. Match fertilizer to Kwale's nitrogen and phosphorus levels for the best result.

Kwale County is a challenging environment for Cape Gooseberry (soil-match score 2/100) and will need significant amendment before planting. Local soils average pH 6.76 — 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 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Cape Gooseberry, which favours loam. At 200 m, the county sits below Cape Gooseberry's preferred altitude range (1200–2600 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Cape Gooseberry is the #92 soil match of the 106 crops we assess for Kwale County. Cape Gooseberry's full potential is about 5,000 kg/acre (~KES 600,000/acre at KES 120/kg), but at Kwale's 2/100 suitability a realistic target here is closer to 125 kg/acre (~KES 15,000/acre) unless the constraints above are addressed.

Better matched to Kwale's soil: Dhania, Pigeon Peas, and Mango — each scores higher on the same soil.
