Tips for vineyard workers
In many grapevines, in the irrigation areas especially, canopies tend to be excessively dense. This causes the inside leaves to be in the shade, which impacts negatively on grape analyses, fertility and diseases, amongst others. Breaking out of leaves, whether manual or mechanical, is rapidly becoming common practice in South Africa.
