What is the main objective of root pruning?

1. Increase water absorption

2. Fit the plant in a hole

3. Develop a compact and fibrous root system

4. Encourage normal stem growth

The correct answer is: Develop a compact and fibrous root system

The primary goal of root pruning is to develop a compact and fibrous root system. When roots are pruned, it encourages lateral growth, leading to a denser root network. This is essential for the overall health of the plant, as it allows for better nutrient and water uptake and enhances stability when transplanted. A fibrous root system is particularly beneficial for young plants, providing a strong foundation that supports vigorous growth and improves their ability to adapt to new environments. In contrast, while increasing water absorption, fitting the plant in a hole, and encouraging normal stem growth may all be related to overall plant health, they do not specifically encapsulate the core purpose of root pruning. Root pruning's emphasis on creating a better root structure ultimately contributes to ensuring that these other factors can be effectively optimized in the long run.
