What are the temperature thresholds for polyethylene planters before they become brittle?
Polyethylene planters are popular for their durability and flexibility, but they can become brittle under extreme temperatures. Typically, polyethylene starts to lose its flexibility and becomes brittle at temperatures below -20°F (-29°C) or above 120°F (49°C). Prolonged exposure to these extremes can cause cracking or breaking. To extend the lifespan of your planters, avoid leaving them in freezing conditions or direct scorching sunlight. For colder climates, consider moving planters indoors during winter or using insulating materials. Understanding these thresholds helps gardeners make informed decisions for long-term use.
