Grapevine

Question

Where can I find Zinc and the cow manure for my Grapevine?

Answer 1

If a soil test has determined that you have a zinc deficiency, you can purchase chelated zinc to work into the soil.
You can easily find soil amendments including the cow manure at garden centers and greenhouses.
