Overview

• Argentine outlets on Aug. 28–29 report specialists recommending wrapping the pot rim or partially covering the soil with foil while keeping it away from the stem.
• Practitioners say the foil creates a physical barrier that discourages crawling pests such as ants and slugs.
• Covering part of the substrate is reported to lower evaporation, helping the soil stay moist longer and reducing water stress.
• The reflective surface can redirect light onto foliage in low-light spaces and help stabilize root-zone temperatures on hot days.
• Coverage pairs the tip with advice on pot size, drainage holes, and material choice, and frames reusing foil as a simple, low-cost sustainability step.
