The "golden" period that decides pepper yield
The flowering – fruit-set stage determines 60–70% of the harvest. Yet many growers face:
- Vines that do not flower or flower very little
- Mass drop of flowers or young fruit
- Empty, uneven, low-quality berries
The cause is often not pests or diseases, but incorrect technique!
5 common mistakes that stop pepper flowering or cause fruit drop
1. Not managing water before flower induction
- Continuous watering → the vine does not "sense" dry stress → no flower buds
- Watering too late or stopping water for too short a time → weak, uneven flowering
Solution:
✅ Stop watering 15–20 days before flower induction
✅ Then resume watering together with fertiliser containing phosphorus and boron
2. Nutrient shortage before and during flower formation
- Lack of phosphorus, potassium, boron, calcium → few, weak flowers that drop early
- Lack of magnesium and zinc → small fruit that drops young
Solution:
✅ Spray NPK 10-30-10 foliar fertiliser + micronutrients
✅ Add Viet-up 90 to improve uptake and reduce wash-off in the rainy season
3. Spraying insecticides and fungicides at the wrong time
- Spraying while flowers are in full bloom → flower shock
- Spraying products with "hot" ingredients → burnt flowers, young fruit drop
Solution:
✅ Stop chemical sprays during flowering
✅ If needed, use only biological products – at low rates – in cool weather
4. Not controlling mealybugs and nematodes during fruit fill
- Mealybugs attack from the flower buds → flowers fail to develop
- Nematodes weaken the roots → the vine cannot support its fruit
Solution:
✅ Use Pilaravia 155SC to control mealybugs early
✅ Stimulate roots and help the vine recover with Besviet 0.02SP
5. No canopy management, dense garden – lack of light
- Canopy too dense → flowers do not get enough sunlight
- High humidity → fungal disease causing flower drop
Solution:
✅ Prune for good airflow – especially around flowering time
✅ Do not let weeds cover the base of the vines
Pepper care calendar to limit flower and fruit drop
| Stage | Tasks | Suggested products |
|---|---|---|
| 30 days before flowering | Manage water, remove old leaves | – |
| 7–10 days before flowering | Spray P + B + KNO₃ + Viet-up 90 | NPK 10-30-10 + B |
| After flowers open | Support flowers – light disease prevention | Zn + Ca + biological products |
| Young fruit set | Stimulate roots, add calcium – magnesium | Besviet 0.02SP |
