Which practice can increase plant resilience to pests?

Choosing plant varieties suited for local conditions is a key practice that can significantly increase plant resilience to pests. When plants are well-adapted to their environment—considering factors like soil type, climate, and local pest populations—they are more likely to thrive and resist diseases and infestations. Native plants or those bred for specific regional challenges often possess natural defenses that help them withstand stressors, including pest pressures.

This practice not only fosters healthier plants but also can reduce the need for chemical interventions, leading to a more sustainable approach to pest management. By selecting the right varieties, gardeners and landscapers create a biological balance that enhances the overall ecosystem, making it more difficult for pests to establish and proliferate.

In contrast, high levels of synthetic fertilizers can lead to various issues, such as nutrient imbalances and increased vulnerability to pests. Overcrowding plant species creates competition for resources, which can stress plants and make them more susceptible to pest attacks. Regular flooding can damage root systems and promote conditions conducive to root rot and other diseases, further weakening the plants and increasing their vulnerability to pests.
