Can watering the leaves of outdoor plants and trees kill the plant or tree?
Watering the Leaves of Plants
Not usually, unless perhaps it is done during the hottest times or most intense sunlight time of the day. The water droplets can act like magnifying glasses and burn the leaves, thus taking away some of the ability of the tree or plant to thrive as it should. I like to wash the foliage of the plants, shrubs, roses and trees as I water them in the early morning or in the evening once the temps have cooled down. It helps open the pores on the leaves and allow them to function better.
