Greenhouse
Bell Pepper

When plants are too close, they compete for light, water, and nutrients. Dense canopy reduces photosynthesis — the plant can't produce enough energy for fruit development.

Solution: Maintain 40–50cm between plants, 75–90cm between rows. Maximum 4 plants per m².

Above 32–35°C causes massive blossom drop. Below 15°C at night impairs pollen production. Nigerian greenhouses can hit 40°C+ without proper ventilation.

Solution: Shade cloth (30–50%), roll-up side vents, ridge vents, misting systems. Monitor with digital thermometers.

Greenhouse air is often too still for effective self-pollination. Flowers need physical agitation to release pollen.

Solution: Introduce bumble bees, use fans for air circulation, manually shake plants every 2–3 days, or hand-pollinate.

Both over-watering and under-watering trigger flower drop. Inconsistent watering creates stress cycles.

Solution: Drip irrigation for consistent, measured watering. Never let growing medium dry out completely.

Insufficient potassium, calcium, boron, and magnesium during flowering directly causes abortion. Many farmers apply fertiliser monthly when bi-weekly is needed.

Solution: Bi-weekly fertiliser during flowering. High-K + Ca formulations. Foliar sprays of calcium and boron.

When a plant carries too many developing fruits, it aborts newer flowers because it can't supply enough energy to all of them.

Solution: Strategic fruit pruning — limit fruits per node. Remove deformed or excess small fruits early.

Thrips, whiteflies, aphids, and spider mites attack flower buds. Root diseases weaken the plant's ability to support fruit.

Solution: Insect-proof netting, yellow sticky traps, neem oil, and integrated pest management.
