Leaves yellowing on all my plants!
Hi! 50% of my plants in my yard have yellowing leaves starting at the bottom of the plant slowing moving upward. I do see some whiteflies around some of the plants but not all of them. When I inspect the undersides of the leaves with a magnifying glass I do see some very very tiny white specks .Are these larvae of whiteflies. You can't see them without the magnifying glass.What can I use to spray that won't harm the plants in this horrible hot summer we are having? I've been afraid to spray anything for fear of the plant dying with all the heat.Any suggestions would be great! The leaves are all yellowing on my plumeria's, some of my hibiscus which are all in pots.I have and Indian Carnation, Lo and Behold Blue Chip and my blue butterfly clerodendrum which seem to be affected the most. Thanks so much!
