Growing Tree Tomato (Tamarillo) in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Kwale County is a challenging environment for Tree Tomato (Tamarillo) (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 6.76 — neutral and inside the 5.8–7 band Tree Tomato (Tamarillo) 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/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Tree Tomato (Tamarillo), which favours loam. At 200 m, the county sits below Tree Tomato (Tamarillo)'s preferred altitude range (1500–2800 m), which limits yield potential due to heat stress. Tree Tomato (Tamarillo)'s full potential is about 8,000 kg/acre (~KES 640,000/acre at KES 80/kg), but at Kwale's 1/100 suitability a realistic target here is closer to 100 kg/acre (~KES 8,000/acre) unless the constraints above are addressed.
