Q: Is there a recipe I can make at home that would work just like Wilt Pruf to put on my Rhododendron? The price of Wilt Pruf is just getting to pricey for me.
Sorry, I know of no home brew that acts as an anti-desicant. Wilt-Stop by Bonide is less expensive and works as well. The concentrate is less expensive than the ready to use. Best And Happy Yardening, Nancy.
