Growing Tree Tomato (Tamarillo) in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Mombasa County is a challenging environment for Tree Tomato (Tamarillo) (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 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 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Tree Tomato (Tamarillo) prefers loam soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. At 50 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 Mombasa's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
