What Factors Should Be Considered When Selecting Plants for Full Sun?

When selecting plants for full sun planter boxes, several key factors should be considered to ensure optimal growth and aesthetic appeal.

• Climate Adaptability: Select plants that are well-suited to the local climate, including temperature extremes and humidity levels. Native plants or those adapted to similar climates often have better resilience and require less maintenance.
• Pest and Disease Resistance: Some plants are more susceptible to pests and diseases, which can be exacerbated by full sun conditions. Choosing healthy, resistant varieties can minimize the need for chemical treatments and promote a more sustainable garden environment.
