The statement that native plants generally need less irrigation than non-native species is accurate due to several reasons related to their adaptations and ecological background. Native plants have evolved within their specific regional environments, developing traits that allow them to survive and thrive with the local climate, soil types, and water availability. As a result, they are typically more resilient to drought conditions and can rely on natural precipitation rather than requiring additional watering.

In contrast, non-native species often come from different environments where water conditions may vary significantly. These plants may not have the same adaptations for conserving water or dealing with local stresses, which can lead to a higher water requirement for their survival and growth.

The other statements focus on various misconceptions. Some native plants can indeed thrive without irrigation, especially those well adapted to arid regions, but this is not universally true across all native species. While certain native plants can perform well with minimal water, they may still benefit from some irrigation during particularly dry spells. Additionally, while specialized irrigation techniques might be employed in specific contexts, most native plants are generally suited to conventional irrigation methods—or none at all—when planted in their native habitats.
