What is the best way to avoid problems with wood-boring insects?

• A. Maintain plant health
• B. Apply pesticides regularly
• C. Prune only in winter
• D. Water heavily

Answer: (A)

Keeping plants healthy is the most effective way to prevent problems from wood-boring insects. When trees and shrubs are well-watered, properly nourished, and protected from wounds and stress, they mount stronger natural defenses and are less attractive to borers. A healthy plant can resist and recover from attacks more easily, reducing the chance that wood-boring insects will take hold or cause serious damage.

Regular pesticide use isn’t the best approach because it targets pests after they appear and can lead to resistance and harm to beneficial insects and the environment. It doesn’t address the underlying health of the plant, which is what truly reduces susceptibility.

Pruning only in winter doesn’t reliably prevent borers. While timing matters for some diseases or other pests, pruning can create fresh wounds that attract borers if not done carefully, and it doesn’t tackle the stress factors that make infestations more likely.

Watering heavily tends to weaken plants by promoting root problems and disease, which increases stress and susceptibility to attacks.
