Growing Rosemary in Nairobi
Soil suitability analysis based on Nairobi's nutrient profile
Yes — Nairobi is well suited to Rosemary. Nairobi's soil (pH 6.85, near-neutral) gives Rosemary a suitability score of 93/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.
Nairobi County is well suited to Rosemary, scoring 93/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 6–8 band Rosemary prefers, so no lime is usually required. Nitrogen (1.1 g/kg), phosphorus (22.1 mg/kg) and potassium (236 mg/kg) all meet Rosemary's requirements, so a maintenance fertilizer programme is enough. Rosemary prefers sandy loam soils, while Nairobi is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Rosemary is the #3 soil match of the 106 crops we assess for Nairobi County. At current prices (about KES 150/kg) and a typical 2,500 kg/acre yield, a well-managed Rosemary crop here can gross roughly KES 375,000 per acre.

Top dressing guide
Nairobi's nitrogen (1.1 g/kg) already meets Rosemary's 0.8 g/kg requirement, so this is a maintenance rate.
