Can cedar planters be lined with plastic to reduce soil contact and prolong life?

Cedar planters are popular for their natural beauty and durability, but prolonged soil contact can lead to rot and decay. Many gardeners wonder if lining cedar planters with plastic can help reduce soil exposure and extend their lifespan.

The answer is yes—using a plastic liner can create a barrier between the soil and the wood, slowing moisture absorption and preventing rot. However, proper drainage must be maintained to avoid waterlogging. Perforated plastic or landscape fabric can be effective alternatives, allowing airflow while protecting the wood.

For best results, choose a high-quality, UV-resistant plastic liner and secure it properly. Regular maintenance, such as checking for trapped moisture, will further prolong your cedar planter’s life. This simple step can keep your garden looking fresh while preserving the natural appeal of cedar.
