What is the recommended approach for pruning trees at planting?

1. Limit pruning to removing dead or damaged limbs

2. Do not prune; let them develop naturally

3. Delay pruning until the third year after planting

4. Cut back trees to at least one-half their size

The correct answer is: Limit pruning to removing dead or damaged limbs

Limiting pruning to the removal of dead or damaged limbs during the planting stage is the recommended approach because it helps promote healthy growth without unnecessarily stressing the young tree. Young trees are still establishing their root systems and overall structure; thus, minimizing interventions allows them to focus their energy on developing roots and acclimating to their new environment. Pruning only those limbs that are dead or damaged ensures that the tree can grow with a natural form while removing any potential hazards that may interfere with its health. This cautious approach also helps reduce the risk of infection or disease entering the tree through pruning cuts, as fresh cuts can create entry points for pests and pathogens. Other methods, such as not pruning at all, can lead to overcrowding as lower limbs may die off due to lack of sunlight. Delaying pruning until a few years down the line might not effectively manage tree shape and structure in the early stages. Drastically reducing a tree's size by cutting back to half can shock the plant, compromising its ability to thrive as it redirects resources to regrowth rather than establishing a strong foundation.
