Which action is considered an essential step in pruning to maintain plant health and form?

• A. Remove dead or diseased wood
• B. Prune only during the hottest part of the day
• C. Cut below a healthy bud
• D. Use unsterilized tools

Answer: (A)

Removing dead or diseased wood is essential in pruning because it targets tissue that can’t contribute to the plant’s health and can harbor pests or pathogens. By taking out this compromised material, you improve air circulation and light inside the canopy, which helps the remaining growth develop more evenly and vigorously. This step directly protects the plant’s health and supports a strong, well-structured form, making future pruning easier and more effective.

Other actions don’t support healthy pruning: pruning during the hottest part of the day stresses the plant and speeds water loss, which can damage young tissue; cutting below a healthy bud can remove the very point from which new growth should emerge; and using unsterilized tools risks spreading disease between plants.
