How to Grow

Cultivation

Although the plants are hardy this cultivar needs to be grown in a greenhouse or conservatory, with heat in the autumn, to produce a decent crop. The vines require regular attention including feeding and watering, pruning and thinning, pest and disease control. See indoor grape cultivation for details

Propagation

Propagate by hardwood cuttings in late autumn or winter, or by softwood cuttings or semi-ripe cuttings from late spring to midsummer or grafting onto Phylloxera resistant rootstocks

Suggested planting locations and garden types

Mediterranean climate plants
Climber and wall shrubs
Conservatory and greenhouse
Edible fruit

Pruning

The main pruning time is early winter (Nov-Dec) but pinching and thinning are needed throughout the growing season. See Grape pruning
