Can I wash my hosta?
We have just been overrun by aphids this year. They've made a nice home in the pecan trees around here. Everthing is covered with that sticky goo commonly referred to as honeydew, including all my hosta. The flies and gnats are thick. My friend suggested that I use dawn dishwashing detergent to wash the hosta. She said her mom used Ivory regularly for insect control and didn't think that it would cause any problems.
I planned to dilute the dawn and put in in a pump up sprayer and spray the hosta leaves and then hose them off. Any ideas, pro or con?
