Growing grapevines in a cold glasshouse in the UK is possible, but it requires careful attention to a few key factors. Here are some tips to help you get started:

Choose a suitable variety: Some grape varieties are more tolerant of cold temperatures than others. Look for varieties that are known to be hardy and are suited to the UK climate, such as ‘Boskoop Glory,’ ‘Madeline Angevine,’ or ‘Siegerrebe.’

  • Select a good location: Choose a spot in your glasshouse that receives plenty of sunlight and has good air circulation. Grape vines need at least 6 hours of direct sunlight per day to thrive. Normally they are planted outside the glasshouse and trained to grow inside or planting in the glasshouse in a soil bed 
  • Prepare the soil: Grape vines prefer well-drained soil with a pH between 6.0 and 6.5. Add compost and organic matter to improve soil fertility and drainage.
  • Plant the vines: Plant grape vines in late winter or early spring, while they are still dormant. Dig a hole that is deep enough to accommodate the roots, and plant the vine so that the base of the stem is just above the soil level.
  • Provide support: Grape vines need a strong support structure to grow on. Install a trellis or wire system along the wall of your glasshouse or overhead.
  • Water and fertilize: Grape vines need regular watering, especially during dry periods. Fertilize with a balanced fertilizer every two weeks during the growing season.
  • Prune the vines: Grape vines need to be pruned regularly to control their growth and promote fruit production. Prune in late winter or early spring, before new growth appears.
  • Harvest the grapes: Grapes are ready to harvest when they are fully colored and slightly soft to the touch. Depending on the variety, this could be anywhere from late summer to early autumn.
