Vine Life - Pruning

Between now and harvest in April 2011, we are going to blog the growing season of a Seresin vine to show how we manage our vineyards and what being biodynamic means for us. Every time we touch this vine, be it pruning, leaf-plucking, or spraying compost tea we'll show you what we're doing and why.

Outside our Cellar Door are a few rows of Semillon vines, the fruit from which makes up around 5 per cent of our Seresin Sauvignon Blanc each year. We have chosen one of these vines to profile.

Yesterday brought the first job of the growing season for this Semillon vine; pruning it to remove last years growth and getting the plant ready to grow again. Here Wendy is removing some of the old wood.

While Semillon is typically spur pruned, we also prune almost all the vines on our estate the same way, which is not so typical. There's a great picture here which shows the difference between spur and cane pruning. We find that spur pruning gives us more control of how the vine grows and the spacing between the shoots. It also means that the vine naturally yields less fruit, which improves quality. It also makes the vine hardier, and gives it a buffer against damage from frost and grass grub.
