Growing Rosemary in Bomet

Soil suitability analysis based on Bomet's nutrient profile

Rosemary can be grown in Bomet County, but the soil scores 53/100 and needs targeted management to reach full potential. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 6–8 band Rosemary prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 mg/kg) all meet Rosemary's requirements, so a maintenance fertilizer programme is enough. Rosemary prefers sandy loam soils, while Bomet is largely clay loam, so drainage and organic-matter management matter more here. Rosemary's full potential is about 2,500 kg/acre (~KES 375,000/acre at KES 150/kg), but at Bomet's 53/100 suitability a realistic target here is closer to 1,656 kg/acre (~KES 248,400/acre) unless the constraints above are addressed.
