Growing Spider Plant (Saga) in Nyandarua
Soil suitability analysis based on Nyandarua's nutrient profile
Nyandarua County is a solid choice for Spider Plant (Saga), with a soil-match score of 70/100. At an average pH of 5.38 the soil is moderately acidic, below Spider Plant (Saga)'s preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Spider Plant (Saga)'s requirements, so a maintenance fertilizer programme is enough. Spider Plant (Saga) prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. Spider Plant (Saga)'s full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Nyandarua's 70/100 suitability a realistic target here is closer to 4,375 kg/acre (~KES 218,750/acre) unless the constraints above are addressed.
