Growing Tree Tomato (Tamarillo) in Kisii
Soil suitability analysis based on Kisii's nutrient profile
Yes, with the right inputs — Kisii is moderately suited to Tree Tomato (Tamarillo). Kisii's soil (pH 5.21, strongly acidic) gives Tree Tomato (Tamarillo) a suitability score of 65/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Kisii County is a solid choice for Tree Tomato (Tamarillo), with a soil-match score of 65/100. At an average pH of 5.21 the soil is moderately acidic, below Tree Tomato (Tamarillo)'s preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.09 g/kg, P 13.1 mg/kg, K 151 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Tree Tomato (Tamarillo), which favours loam. On ShambaIQ's soil-match model, Tree Tomato (Tamarillo) is the #36 soil match of the 106 crops we assess for Kisii County. Tree Tomato (Tamarillo)'s full potential is about 8,000 kg/acre (~KES 640,000/acre at KES 80/kg), but at Kisii's 65/100 suitability a realistic target here is closer to 6,500 kg/acre (~KES 520,000/acre) unless the constraints above are addressed.
