Growing Spider Plant (Saga) in Machakos

Soil suitability analysis based on Machakos's nutrient profile

Machakos County is well suited to Spider Plant (Saga), scoring 80/100 on ShambaIQ's soil-match model. At an average pH of 7.03 the soil sits above Spider Plant (Saga)'s preferred 5.8–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.82 g/kg, P 31.4 mg/kg, K 338 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit.
