Top 10 Questions for Vine Pruner Interview

1. Describe the different types of vine pruning techniques?

• Cordon pruning: This technique involves training the vine to grow along a horizontal wire, with canes (lateral shoots) growing vertically from the cordon. This method is commonly used for wine grapes and table grapes.
• Guyot pruning: This technique involves leaving two canes on each vine, with one cane trained horizontally and the other vertically. This method is also used for wine grapes and table grapes, and it is known for producing high-quality fruit.
• Head pruning: This technique involves cutting back the vine to a single head, or stump, each year. This method is used for grapes that are grown for raisins or for making juice.
• Cane pruning: This technique involves leaving several canes on each vine, with each cane trained vertically. This method is used for grapes that are grown for wine or for making juice.

2. What are the key factors to consider when pruning vines?

Vine age and vigor

• Younger vines need more aggressive pruning to shape the vine and encourage fruit production.
• Older vines may need less pruning, but it is still important to remove dead or diseased wood and to thin out crowded canes.

Grape variety

• Different grape varieties have different pruning requirements.
• For example, wine grapes typically require more aggressive pruning than table grapes.

Climate and soil conditions

• In warm climates, vines may need to be pruned more heavily to reduce sun exposure and prevent sunburn.
• In cooler climates, vines may need to be pruned less heavily to allow for more sunlight exposure.

3. What are the common mistakes to avoid when pruning vines?

• Over-pruning: This can weaken the vine and reduce fruit production.
• Under-pruning: This can lead to overcrowding and reduced fruit quality.
• Pruning at the wrong time of year: This can damage the vine and reduce fruit production.
• Using the wrong pruning tools: This can make pruning more difficult and can also damage the vine.
