Treatment Plan

Vineyard nitrogen status is typically determined by visual observations of canopy fill and leaf color.  Nitrogen deficiency is associated with pale green to yellow leaf color, short internode length, and inadequate vegetative growth.  Bloom petiole sampling can be used to verify nitrogen deficiency if needed – contact our office if nitrogen analysis is desired for bloom petiole samples as this is not included with our typical petiole analysis and requires an additional fee.
