Growing Rosemary in Homa Bay

Soil suitability analysis based on Homa Bay's nutrient profile

Rosemary can be grown in Homa Bay County, but the soil scores 56/100 and needs targeted management to reach full potential. At an average pH of 5.27 the soil is moderately acidic, below Rosemary's preferred 6–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.05 g/kg, P 13.8 mg/kg, K 147 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Rosemary prefers sandy loam soils, while Homa Bay is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Rosemary is the #77 soil match of the 106 crops we assess for Homa Bay County. Rosemary's full potential is about 2,500 kg/acre (~KES 375,000/acre at KES 150/kg), but at Homa Bay's 56/100 suitability a realistic target here is closer to 1,750 kg/acre (~KES 262,500/acre) unless the constraints above are addressed.

Better matched to Homa Bay's soil: Macadamia, Avocado, and Pineapple — each scores higher on the same soil.
