Guava farming guide — Kenya

Soil requirements

Growing conditions for Guava

Guava does best with 700–1,800 mm of rainfall a year at 0–1,800 m above sea level. In drier areas, irrigation or water harvesting closes the gap; outside the altitude band, growth and yields drop.

Optimizing soil and fertilizers for Guava in Kenya

To achieve maximum yields when farming guava in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 5.5 to 7.5. Soils that fall outside this range can lock out essential macro and micro-nutrients, leading to stunted growth or crop failure. For acidic soils, applying dolomitic or calcitic agricultural lime is recommended at least 30 days before planting to normalize acidity.

Fertilizer application should be calibrated based on the crop’s nutrient demands. Guava has a medium nitrogen requirement, medium phosphorus requirement, and medium potassium demand. Using certified seed varieties suited for your specific altitude and rainfall pattern, combined with a precise basal and top-dressing program (such as applying CAN at Twice per year at start of rains), ensures high crop quality and protects your overall farm investment.

How to grow guava in Kenya

1. 1
   Prepare the soil

   Ensure soil pH is between 5.5 and 7.5. Preferred texture: Loam. Apply agricultural lime if your pH is below 5.5, ideally 30 days before planting.
2. 2
   Plant at the right time

   Plant guava during Long Rains (Transplanting & Basal–Fruit Development) or Short Rains (Transplanting & Basal–Fruit Development), timed to the start of the rains.
3. 3
   Apply basal fertilizer

   Guava needs medium nitrogen, medium phosphorus, and medium potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
4. 4
   Top-dress

   At Twice per year at start of rains, apply 0.5 bag(s) per acre of CAN. Ring-apply around the drip line. Add NPK at flowering.
5. 5
   Monitor and harvest

   Scout regularly for pests and disease. Expected yield is about 10,000 kg/acre at roughly KES 60/kg.

Planting calendar

Establishment timeline

Guava is a perennial — it takes ~2 years to first harvest before your first crop, then yields for many years. Here is what each stage involves.

1. Year 0 — Planting

   Plant grafted or seedling trees 4–5 m with manure.

2. Year 1 — Vegetative

   Prune to shape, weed, irrigate.

3. Year 2 — First fruit

   First flowering and fruit; control fruit fly.
