Growing grapevine in (or into) the greenhouse — shade, humidity and autumn fruit

Growing a grape vine in a glasshouse provdes humidity during a hot summer

A grapevine trained into or across the greenhouse gives summer shade, humidity and autumn fruit — a lovely multi-purpose solution.

How to do it simply

• Site & support: Plant a young vine next to the greenhouse wall and run wires or rope into the greenhouse roof. Train lead shoots horizontally along wires to encourage fruiting. GardenAdvice recommends training and establishing vines in the greenhouse for shade and to speed crop growth.
• Training & pruning: Train two or three main canes horizontally along wires and prune in winter/dormant season to the framework that suits your variety. Remove excess laterals to focus vigour into fruiting canes.
• Benefits: Vines create shade and higher humidity for summer crops (helpful for melons/tomatoes), and produce bunches of grapes from late summer/autumn if trained and pruned properly.
