Prof. Samuel Fitzgerald, Ph.D.Bell peppers prefer consistently moist... without being waterlogged. Water deeply so that plants receive 1-2 inches per week, tested with a rain gauge or a container filled with water. Adjust watering according to extreme weather conditions: water more during heatwaves and less during cooler weather. A consistent supply of moisture is needed to prevent dropping blossoms and cracking fruit.
Timing & Method
- Water at soil level using soaker hoses or drip systems
- Always water before 10am to allow leaf drying
- Avoid overhead watering to prevent fungal diseases
Moisture Conservation
- Apply 3-inch organic mulch layer around plants
- Use straw or shredded leaves for best results
- Replenish mulch monthly as it decomposes
Special Conditions
- Double water frequency during 90°F+ heat waves
- Reduce to bi-weekly when temperatures drop below 60°F
- Pause watering entirely during rainy periods
The type of soil also affects how quickly it absorbs water; sandy soils dry out much faster and require more frequent soaking, while clay holds moisture for longer. A good handful of compost can mitigate any shortcomings. I thrust my finger 2 inches down into the soil. If it feels dry at that depth, I'll give it a good soak.
Be aware of the signs of water stress immediately. If your plant has droopy leaves in the morning, it likely needs water immediately. Leaf curling can indicate chronic water stress. Slow yellowing of the lower leaves may mean it has too much water. Update your watering schedule according to your plant's specific needs.
Drip irrigation systems apply water efficiently. Place emitters at the base of plants, not at the stem. Run the systems for at least 30 to 45 minutes per irrigation session. Timers are used to ensure each plant is watered consistently, especially if you are away for several days, to prevent underwatering.
Watering adjustments may be needed with the seasons. Water more often during the hot summer months, and less frequently as the weather cools in the fall. Stop watering the overwintering plants completely over the winter season. When new growth appears in the spring, you can resume watering.
Harvest timing affects water needs. Stop watering 24 hours before picking for firmer fruits. Resume immediately after harvesting. This technique extends storage life while maintaining plant health for continued production.
