Why Pepper Plants Flower but Don't Set Fruit

Top Causes

1. Poor pollination — peppers are self‑pollinating but benefit from bee vibration. Gently shake plants every few days. Plant flowers (sunflowers, marigolds, cosmos) to attract bees.
2. Overwatering — water deeply 1–2×/week (1.5" total), not daily. Mulch heavily.
3. Excess nitrogen — lush leaves, few fruit. Switch to high‑phosphorus/potassium fertilizer (tomato/pepper formulas).

Summary Checklist

• Fertilize low‑N, high‑P/K every 2 weeks.
• Water deeply, infrequently.
• Mulch with straw/grass clippings.
• Shake plants gently for pollination.
