Growing Celery in Kwale
Soil suitability analysis based on Kwale's nutrient profile
Generally not ideal — Kwale is poorly suited to Celery. Kwale's soil (pH 6.76, near-neutral) gives Celery a suitability score of 3/100. Match fertilizer to Kwale's nitrogen and phosphorus levels for the best result.
Kwale County is a challenging environment for Celery (soil-match score 3/100) and will need significant amendment before planting. Local soils average pH 6.76 — neutral and inside the 6–7.5 band Celery prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Celery, which favours loam. At 200 m, the county sits below Celery's preferred altitude range (1000–2600 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Celery is the #85 soil match of the 106 crops we assess for Kwale County. Celery's full potential is about 12,000 kg/acre (~KES 840,000/acre at KES 70/kg), but at Kwale's 3/100 suitability a realistic target here is closer to 450 kg/acre (~KES 31,500/acre) unless the constraints above are addressed.
Better matched to Kwale's soil: Dhania, Pigeon Peas, and Mango — each scores higher on the same soil.

Top dressing guide
Kwale's nitrogen (0.93 g/kg) is 78% of the 1.2 g/kg Celery needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
