Growing Dragon Fruit in Garissa
Soil suitability analysis based on Garissa's nutrient profile
Generally not ideal — Garissa is poorly suited to Dragon Fruit. Garissa's soil (pH 7.96, alkaline) gives Dragon Fruit a suitability score of 15/100. Match fertilizer to Garissa's nitrogen and phosphorus levels for the best result.
Garissa County is a challenging environment for Dragon Fruit (soil-match score 15/100) and will need significant amendment before planting. At an average pH of 7.96 the soil sits above Dragon Fruit's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.61 g/kg, P 37.7 mg/kg, K 407 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Dragon Fruit, which favours sandy loam. Garissa receives approximately 250 mm/year — well below Dragon Fruit's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Dragon Fruit is the #26 soil match of the 106 crops we assess for Garissa County. Dragon Fruit's full potential is about 5,000 kg/acre (~KES 2,500,000/acre at KES 500/kg), but at Garissa's 15/100 suitability a realistic target here is closer to 938 kg/acre (~KES 469,000/acre) unless the constraints above are addressed.
Better matched to Garissa's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
