What type of pruning is typically performed during the dormant season?

1. Maintenance pruning

2. Structural pruning

3. Formative pruning

4. Renewal pruning

The correct answer is: Structural pruning

Structural pruning is typically performed during the dormant season as it focuses on the fundamental shape and framework of the plant. This type of pruning is essential for young trees and shrubs because it helps establish a strong structure, promoting healthy growth and reducing the risk of damage from wind or heavy snow loads. Performing structural pruning while the plant is dormant minimizes stress on the plant and allows for better healing, as the tree is not actively growing in winter. During the dormant season, it is easier to see the architecture of the tree without the distraction of foliage, which aids in making informed cuts that will enhance the plant's shape and overall health. Additionally, pruning during this time can also help prevent the spread of diseases and pests that are more likely to affect fresh cuts during the growing season. By practicing structural pruning in the winter months, landscape horticulturists ensure that the plants maintain an optimal structure for future growth, leading to healthier, more resilient specimens.
