How does proper pruning promote plant health in shrubs and trees?

• A. Increases trunk diameter rapidly by stimulating growth.
• B. Improves air movement and light penetration, removes diseased wood, and encourages healthy new growth.
• C. Makes plants more drought-sensitive.
• D. Reduces flowering potential.

Answer: (B)

Pruning promotes plant health by opening up the canopy to air and light, which helps leaves photosynthesize efficiently and dries leaf surfaces more quickly to reduce disease risk. It also allows you to remove branches that are diseased, damaged, or crowded, preventing the spread of pathogens and decay through the plant. By directing growth to healthy shoots, pruning encourages vigorous new growth that strengthens the plant’s structure and resilience to stress. The idea is that better air circulation and light, plus removal of problem wood, combine to keep shrubs and trees healthier overall and easier to maintain. In contrast, simply pruning to increase trunk diameter isn’t how growth works, and pruning isn’t inherently about making plants more drought-sensitive. Also, pruning doesn’t automatically reduce flowering potential; in many cases, it can even enhance flowering depending on the species and timing.
