Why Are the Leaves of My Bean Plant Drying Out and Falling Off?
Bean plants are susceptible to several factors that can cause their leaves to dry out and fall off. Here are some of the most common causes:
- Water stress: Bean plants need regular watering, especially during hot, dry weather. When the soil becomes too dry, the plant will be unable to absorb enough water, leading to leaf drying and wilting.
- Nutrient deficiency: Bean plants need adequate nutrients, including nitrogen, phosphorus, and potassium. If the soil is lacking in any of these nutrients, the plant may exhibit symptoms of nutrient deficiency, including yellowing or browning leaves.
- Pest infestation: Pests such as aphids, mites, and whiteflies can feed on bean plants, causing damage to the leaves and weakening the plant. This can lead to leaf drying and falling off.
- Disease: Bean plants are susceptible to several diseases, including bacterial blight, powdery mildew, and rust. These diseases can cause damage to the leaves, leading to drying and falling off.
- Cold damage: Bean plants are sensitive to cold temperatures. If temperatures drop below 10°C (50°F), the leaves may become damaged and fall off.
