Planting Guide

To successfully establish your 'Trollhaugen' Grapevine and ensure vigorous development, follow these key steps:

1. The ideal location: Choose a location in full sun to boost sugar production and ensure optimal coloration of the grapes. Provide a sturdy support such as a trellis, fence, or pergola to sustain its growth and allow good air circulation.
2. Soil preparation: This vine thrives in well-drained, loose, and fertile soil. It adapts to various soil types but dislikes standing water. Mix high-quality compost into your soil when planting.
3. Planting out: Dig a hole twice as wide as the root ball. Position the plant so the root crown sits flush with the surrounding ground level. Fill the hole, tamp gently to eliminate air pockets, and water thoroughly. Space your plants 2.5 to 3 metres apart.
4. Pollination:
   • Type: Self-fertile. The 'Trollhaugen' Grapevine fruits abundantly without requiring another vine nearby.
   • Suggested partners: No companion plant is necessary.

Care and Maintenance Guide

• Watering: Water regularly during the first year to encourage deep root establishment. Once well-established, it shows good drought tolerance, but steady moisture supports optimal berry swelling.
• Fertilization: Apply a generous layer of compost at the base of the plant every spring to nourish the soil. A balanced small fruit fertilizer at the start of the season effectively boosts healthy new growth.
• Pruning: Perform a heavy pruning in late winter or very early spring while the vine is still dormant. This essential step shapes the plant, controls its vigor, and maximizes fruit production on new canes.
• Protection:
  • Against birds: Protect your clusters by installing bird netting as soon as the fruit begins to change color, as birds highly covet its sweet taste.
  • Winter care: Thanks to its remarkable cold hardiness (Zone 3), this vine easily withstands Canadian winters without requiring any special winter protection once established.
