What indicates the right time to stop pruning Tokay grapevines?

The most suitable time to stop pruning Tokay grapevines is when the sap begins to run. This physiological response indicates that the vines are transitioning from dormancy to active growth, meaning they are ready to start growing new shoots and leaves. Pruning at this time can be detrimental, as it may remove buds that are about to break, potentially impacting the vine's yield and vigor for the upcoming growing season.

Pruning too late, after the sap has started flowing, can lead to excessive sap loss, which weakens the vines and might encourage diseases or pests to take hold. Therefore, recognizing the moment when the sap starts to run is essential for effectively timing pruning activities to ensure the healthiest growth of the Tokay grapevines.
