Is foliar nutrition worthwhile? Foliar nutrition is really only a temporary solution. The biggest contribution of foliar nutrition is that it stimulates the plant to take up or extract more of a specific element from the soil (if such element is indeed available in the soil). You can nourish the plant with foliar nutrition applications, but if you do not have good soil fertility, the plant will ultimately display the same symptoms again. Early in the season, when the soil temperature is still low and the root activity starts to increase, foliar nutrition applications can help to combat spring fever in the vineyard. Foliar feeds are also mostly micro-element-driven, and these additions are most effective before flowering. See you in the profile pit! 
