Which of the following practices would not help manage pests in roses?

Neglecting plant care is the practice that would not help manage pests in roses because a healthy plant is less susceptible to pest infestations. When plants are properly cared for, they are typically stronger and can better withstand stressors, including pest attacks. Good plant care practices include appropriate watering, fertilization, and maintenance, all of which contribute to the overall health of the rose plants.

In contrast, regular pruning helps to remove dead or diseased material, which can harbor pests. Applying chemical controls can be effective when targeted and used correctly, while monitoring for signs of infestations enables early detection and management of pest problems. Together, these practices create a proactive approach to pest management, whereas neglecting care allows pests and diseases to thrive without intervention.
