Vitus Madeleine Sylvaner Care.
Vitis ‘Madeleine Sylvaner’ you will indeed need to trim it.The best time to prune vines is during November or December after a spate of cold weather, when the sap is down at the base of the plant.They can be cut back quite hard.Here I have outlined the way to prune your grape like a cordon. Initially you want to shorten the new growth of the main shoot, ‘the leader’, by one half.Once you have reached the top of your support then you want to allow approximately one inch of growth each subsequent season cutting back to a bud.The side shoots, ‘the laterals’ need to be cut back an inch from the leader.It is on these side shoot that the fruiting spurs will be formed.In the spring and summer you need to train the side shoots horizontally pruning the side shoots leaving five leaves on them. At first you do not want your plant to fruit too much so limit the number of trusses on a branch by pruning . This means that the grapes left on the plant will be bigger because the plants energies are concentrated into fewer trusses. Madeleine Sylvaner is a great variety for our climate as it flowers late and ripens early so is useful for cooler areas.It is good as a grape for eating and wine making.
