Growing Rosemary in Laikipia
Soil suitability analysis based on Laikipia's nutrient profile
Yes, with the right inputs — Laikipia is moderately suited to Rosemary. Laikipia's soil (pH 4.99, strongly acidic) gives Rosemary a suitability score of 61/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Laikipia County is a solid choice for Rosemary, with a soil-match score of 61/100. At an average pH of 4.99 the soil is strongly acidic, below Rosemary's preferred 6–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 mg/kg) all meet Rosemary's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Rosemary, which favours sandy loam. On ShambaIQ's soil-match model, Rosemary is the #48 soil match of the 106 crops we assess for Laikipia County. Rosemary's full potential is about 2,500 kg/acre (~KES 375,000/acre at KES 150/kg), but at Laikipia's 61/100 suitability a realistic target here is closer to 1,906 kg/acre (~KES 285,900/acre) unless the constraints above are addressed.
