Pests

Aphids and whiteflies can damage plants by damaging and curling leaves. Whiteflies are hard to spot due to their translucency, but insecticide sprays or natural remedies can help get rid of them.

Overwatering

Overwatering plants can lead to root rot. Adopt a less-is-more approach to watering, allowing the soil to dry before watering again and using containers with drainage holes and gravel.

Heat stress

Plants need warmth but excessive heat can be harmful, causing leaves to curl up. Relocate plants to a cooler area instead of watering them more.

Nitrogen deficiency

Amino-acid supplements can help save dying houseplants by enhancing their ability to absorb and utilize nitrogen effectively, a key ingredient in chlorophyll.

Viral infection

Curling leaves in plants could indicate a viral infection. But unfortunately, there's no cure for it. To prevent spreading, remove affected plants and inspect nearby ones for symptoms.
