Buying Guide
What size should you choose? Align liner length and depth with your window box or railing planter. Typical sizes include 24 inches for smaller boxes and 30 inches for larger displays. If you have irregular planters, consider a roll that you can cut to fit.
What material matters? Natural coconut fiber provides porosity for drainage and airflow, which supports root health and reduces soil compaction. It is environmentally friendly and visually rustic, suitable for outdoor use in many climates.
How easy is installation? Pre-formed liners save time and ensure a stable fit. For custom shapes, a roll or flexible liner lets you tailor coverage, but may require trimming and shaping for a clean edge.
What about drainage and moisture? Coconut liners help moisture retention while allowing excess water to drain. Ensure your planter has drainage holes and avoid overwatering, especially in hot or dry conditions.
Maintenance tips: Rinse liners between seasons if they become stained or moldy. Allow liners to dry before reinsertion to prevent mold growth. Replacing liners periodically keeps planters looking fresh and supports plant health.
