Growing Tree Tomato (Tamarillo) in Nyamira
Soil suitability analysis based on Nyamira's nutrient profile
Nyamira County is a solid choice for Tree Tomato (Tamarillo), with a soil-match score of 68/100. At an average pH of 5.58 the soil is slightly acidic to near-neutral, 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 0.84 g/kg, P 11.6 mg/kg, K 148 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits.
