What your vines need is largely a function of the soil. If you have a local county co-op or agent, you should be able to get soil sample boxes, follow the instructions on how to sample and fill them, and mail them off. In a few weeks, you'll get results back along with fertilizer / soil amendment recommendations, based upon the type of crop you are going. I do this sampling/testing/fertilizing at my hunting property every three years, it's really pretty easy......Is there a good general fertilizer to apply to first and second year vines? What about Miracle Grow?
Hooo, boy. Sounds like a George Carlin routine coming.Else, there is mostly only lime sulfur or copper for organic.
I understand this is not a serious comment.Why do we call inorganic chemical compounds "organic" but most organic chemical compounds don't qualify as organic?
(This is not a serious comment on your post, Balaton. Just a wry observation on language.)
