Curling Leaves
Leaf curling is a stress response where leaves roll inward or outward. It can indicate watering issues, environmental stress, or pest activity.
संभावित कारण
Underwatering
Why: Plants curl their leaves to reduce surface area and minimize water loss through transpiration.
Signs to check: Soil is dry, leaves curl inward, plant may also be drooping.
Low Humidity
Why: Dry air causes excessive moisture loss from leaves, triggering curling as a defense mechanism.
Signs to check: Leaf edges curl inward, tips may also be crispy, common during winter.
Heat Stress
Why: Excessive heat causes leaves to curl to protect themselves from further moisture loss.
Signs to check: Plant is near a heat source, leaves curl upward, soil dries quickly.
Pest Damage
Why: Sap-sucking pests like aphids or thrips can cause leaves to distort and curl.
Signs to check: Sticky residue on leaves, visible insects, new growth is distorted.
