Calcium nitrate for grapes
I have read on several ag extension and nursery websites that calcium nitrate should be applied to 1st year grape plants once per month through the summer. It also says to apply 10-10-10 once per month through the summer as well (apply each 15 days apart)
Do you recommend the calcium nitrate? What is this supposed to do? I assume the nitrates are the good guy here. Could nitrate of soda be a substitute? I can only find calcium nitrate online.
