What should be done to prevent disease after pruning?

To prevent disease after pruning, ensuring proper disposal of pruned material is essential. When grapevines are pruned, the cuttings can harbor pathogens such as fungi and bacteria. If these materials are left on the ground, they may lead to the spread of disease either by direct contact with the plant or by creating a habitat for pests that could further compromise the vines' health.

By removing and disposing of pruned material, you significantly reduce the risk of diseases that may affect the grapevines and ultimately the quality of the grapes. This practice helps maintain a cleaner vineyard environment and supports the overall health of the vine.

Other approaches like leaving pruned material on the ground could expose the vines to pathogens, applying fertilizer immediately might not directly address disease prevention, and pruning only at night does not have a proven impact on reducing disease risks associated with pruning wounds.
