Prune Grapevines

Prune Grapevines before Christmas (or very early in the New Year) to avoid bleeding of stems as the sap starts to rise in the spring.

Shorten the new growth by half and cut back some side shoots back to one bud from the leading stem and others to two buds with sharp Secateurs, these will form the fruiting spurs.

Cut back developing main stems by half their new growth, and established stems to a single new bud.

Later in the summer you can shorten non-flowering laterals to four or five leaves and any side shoots growing from these, to one leaf.
