HAOVZRI 24" Coco Coir Trough Liners — 2-Pack 24in Half‑Moon Planter Liners, Biodegradable, Improved Drainage

HAOVZRI 2-piece 24" coco coir trough liners are biodegradable half-moon coconut fiber liners made to fit window boxes, railing planters, and hanging baskets for improved drainage and healthier root growth.

These molded coir liners come as a matched pair sized to suit most standard 24-inch troughs and window boxes. Constructed from 100% natural coconut fiber, the liners are thick enough to hold soil yet porous enough to increase aeration and drainage. They arrive folded for compact storage and expand easily after a brief soak in water to conform to curved or straight planter interiors.

How do these liners help plants in confined planters?

The coir fiber structure balances moisture retention with airflow so roots get oxygen without staying waterlogged. That makes them useful in shallow or narrow planters where soil compaction and poor drainage often limit growth. Using a liner reduces soil loss through gaps while maintaining a natural root environment.

• Promotes even drainage and prevents standing water
• Improves root aeration for stronger plant development
• Retains enough moisture to reduce watering frequency
• Prevents soil from falling through basket slats or drainage holes

Will these half‑moon liners fit my existing boxes and baskets?

The semi-circular (half-moon) mold is designed to fit most common window boxes, railing planters, and wall-mounted troughs. Because the material is flexible, you can trim or fold the liner for a snug fit in nonstandard shapes. For the best result, measure the internal dimensions of your planter before installing.

• Designed for typical 24" troughs and window boxes
• Flexible coir can be trimmed or shaped to fit
• Foldable for storage and easy transport
• Simple to press into curved or flat planter interiors

How do I prepare and install the coir liners?

Installation is straightforward: briefly soak each liner to soften the fibers, press it into the planter so edges align, and add potting mix. The soak helps the liner expand and take the planter’s shape. Secure the liner with staples, clips, or by tucking the rim under planter edges as needed.

• Soak liners in water for a few minutes to soften and expand
• Press into place and adjust shape before adding soil
• Fill with well-draining potting mix and plant as usual
• Trim excess fiber with scissors for a tailored fit

Where are these liners best used around the home or garden?

They’re suitable for many container settings where a breathable, biodegradable liner is preferred. Use them in balcony railings, window sill boxes, hanging wall troughs, or decorative railing baskets. Their natural look blends with plantings and they decompose over time if left in place.

• Window boxes and sill planters for homes and apartments
• Railing and balcony planters that need lightweight liners
• Wall-mounted troughs and fence baskets for vertical gardening
• Temporary displays for events, weddings, or seasonal décor

Who is this for: Gardeners seeking an eco-friendly, ready-to-shape liner for 24" troughs and half-moon planters will appreciate this two-piece set. It’s ideal for apartment balconies, cottage-style window boxes, and anyone who wants a natural, breathable alternative to plastic liners. If you prefer a low-waste option that supports healthy drainage and easy planting, these HAOVZRI coir liners are a practical choice.
