Q&A Home

Rick from Clarkston, Wa writes,

Can the Peters Professional Liquid S.T.E.M fertilizer be applied as a foliar spray for wine grapes? Rate?


The product label states that the product can be used as a soil drench or a foliar spray as a supplement product with other fertilizers being used for plants. However, it does not specifically state whether it can be used on grapes or edibles in general. We would suggest contacting the manufacturer directly at 800-492-8255.
