Why Pepper Plants Grow Leaves But No Flowers: Nitrogen and Temperature

Introduction

Lush pepper foliage with few flowers points to two common causes.

Excess Nitrogen Promotes Foliage

High-nitrogen fertilizer encourages leaves at the expense of blooms. Use balanced or high-phosphorus fertilizer.

Temperature Sensitivity for Flowering

Nights below 60°F prevent flower set; days above 90°F cause flower drop.

Conclusion

Cut nitrogen, monitor temperatures, and peppers will flower when conditions are right.
