What slope angles require anchoring systems for rattan outdoor planters?

When placing rattan outdoor planters on sloped surfaces, anchoring systems are essential to prevent tipping and ensure stability. Generally, slopes with angles exceeding 15 degrees require anchoring, especially in windy or uneven terrains. For steeper slopes (20 degrees or more), robust anchoring solutions like stakes, weights, or wall mounts are highly recommended. Lighter rattan planters may need anchoring even on gentler slopes due to their lower center of gravity. Always consider local weather conditions and planter size when determining the need for anchoring. Proper installation enhances safety and longevity, keeping your garden both beautiful and secure.
