So I got back from my uncles house and I brought these fresh nice organic non pesticide grape leaves/rose of sharron, and am wondering what I should do before I feed them and how to make them last the longest. I noticed on the back of the rose of sharron leaves there is the little white fly dots, I know if I soak them in a bag with alittle dawn and water it will get rid of them, but not sure if thats ok. Thanks for the advise.
