Planting and caring for high-yield, sustainable pepper
Ideal growing conditions for pepper
Pepper grows well with:
- Temperature: 25–28°C
- Rainfall: 2.000–2.500mm/year, with good drainage
- Soil: Red basalt soil, loose, pH 5.5–6.5
- Light: enough sun, with light shade in the first 1–2 years
Pepper planted in low-lying, waterlogged or nutrient-poor soil is prone to quick wilt and slow decline.
Planting pepper – the stage that decides 80% of success
✅ 1. Preparing support posts
- Living posts: kapok, muồng đen (Senna siamea), keo dậu (Leucaena) – provide windbreak; soft bark is easy to climb
- Dead posts: concrete or hardwood stakes – 3–4m high, buried 60–70cm deep
✅ 2. Digging holes – preparing the soil
- Hole size: 60x60x60cm
- Mix topsoil with 10–15kg well-composted manure + 0.5kg lime + 0.5kg phosphate
- Leave for 20–30 days beforehand to treat pathogens
✅ 3. Planting cuttings
- Choose healthy cuttings with good dormant buds, free of pests and diseases
- Plant 10–15cm from the post and tie loosely to it
- Shade for the first 1–2 months; water to keep moist
Caring for pepper – from rooting to fruiting
1. Fertilising – balanced nutrition
| Stage | Fertiliser type | Suggested rate |
|---|---|---|
| Years 1–2 | Manure + NPK 16-16-8 + micronutrients | 2–3 applications/year |
| Year 3 onwards | NPK + KNO₃ + microbial fertiliser | 3–4 applications/year, plus foliar fertiliser |
Add Viet-up 90 when spraying foliar fertiliser for good adhesion and fast penetration, especially in the rainy season.
2. Watering and keeping moisture
- Dry season: water 2–3 times/week
- Rainy season: ensure fast drainage
- Mulch the base with straw or dry leaves to reduce evaporation
3. Pruning – shaping the canopy
- Remove water shoots, diseased branches and branches growing inside the canopy
- Keep the canopy open for easier spraying and even light
4. Regular pest and disease prevention
| Disease/pest | Solution |
|---|---|
| Mealybugs, aphids | Use Pilaravia 155SC + Viet-up 90 (two-way systemic insecticide) |
| Nematodes, root rot | Mix lime + microbial products; use Besviet 0.02SP to stimulate healthy roots |
| Pink disease, slow decline | Rotate products; improve the soil after each season |
