Pests in Gardens and Landscapes

Physiological leaf roll

Symptoms of leaf roll include the downward rolling of leaves, generally on all plants, with no yellowing of new leaves and no stunting.


Physiological leaf roll is very common. This is not caused by a pathogen. No action is needed. It will not harm plants.
