There's a thing called foliar spraying, where you do spray water and nutrients on the leaves. You don't do it in the sunshine though because the water droplets will magnify the light and burn the leaves.
- Kerrick 2y agoThis magnifying glass effect is a pervasive and dangerous (to thirsty plants) garden myth. Don’t let sunshine stop you from watering a plant that’s suffering from lack of water. https://s3.wp.wsu.edu/uploads/sites/403/2015/03/leaf-scorch.pdf https://s3.wp.wsu.edu/uploads/sites/403/2015/03/leaf-scorch....
- thatcat 2y agoThanks for busting that myth. Foliar isn't about hydration state, it has chemicals and surfactants and it's recommended to do it in morning/night. according to this AL extension office, it can causes a phytotoxicity (leaf burn) at high leaf temps (probably because higher uptake rate of the chemicals) https://www.aces.edu/blog/topics/lawn-garden/foliar-feeding-vegetables/ https://www.aces.edu/blog/topics/lawn-garden/foliar-feeding-...
