Tuck shoots in as normal, but ensure that there are enough shoots going through the foliage wires and good density for the top part of the canopy. All remaining shoots are raked out and the bottom foliage wire is allowed to rest on these shoots. The weight of the wire will force the shoots downward systematically. The bottom wire is then hooked in two to three weeks later. It is better to perform this hook-in action later in the day when it is warm instead of early morning. The shoots will then be more pliable and less likely to break. Contact your viticulturist for advice on hooking off of shoots. It is critical to hook shoots off to the right side in order to prevent sunburn. This action will vary between regions and localities. The top of the canopy is otherwise managed as normal and tipping/ topping actions are performed as normal. The downward positioned shoots are not tipped/topped. Ballerina Allow vineyard to grow as normal. In areas with little wind, the foliage wires can be lifted up or affixed to the post permanently. When the shoots have grown far enough through the foliage wires, the raking-out action can commence. Ensure that there are enough shoots going through the Snoei
