2PCS 22 in Coconut Liners for Half Round Planters - Moisture Retention

Our review of the 2PCS 22 in coconut liners finds them best suited for gardeners who want a natural, breathable planting surface for half round troughs and hanging boxes. The single biggest reason to buy is the material: these liners are 100% natural coco fiber that holds moisture while allowing good drainage and air circulation, making them a simple replacement for worn or missing half round liners. They are offered as a two pack, which is convenient for matching pairs of window boxes or replacing liners in multiple containers at once.

Key Features

• 22 in width: Sized to fit many half round planters and window troughs so installation is straightforward for compatible containers.
• 100% natural coco fiber: Made from renewable resources to provide a biodegradable planting surface that supports healthy root aeration.
• Moisture retention and drainage: The liner holds moisture against the root zone while still allowing excess water to drain away, reducing waterlogging risk.
• Good air circulation: The fibrous structure helps air reach roots, which benefits many potted ornamentals and bedding plants.
• Two pack convenience: Comes as a pair so you can outfit two planters or have a spare liner ready for rotation.

Who It's For

This product is aimed at hobby gardeners, apartment balcony growers, and landscapers who use half round troughs, window boxes, or wall-mounted planters and prefer natural materials. It is especially useful for those who want improved drainage and root aeration compared with non-breathable liners.

Gardeners who need an exact custom fit should measure their planters first; some customers reported mixed fit depending on planter shape and internal dimensions. If you require a different shape or an exact bespoke size, look for other liner shapes or sizes rather than assuming a universal fit.
