Bosmere F919 Pre-Formed Coco Liner with Soil Moist — 30-Inch Replacement Liner for Window Boxes & Baskets

Refresh Your Planters with a Smart, Breathable Liner

Give 30-inch window baskets and planter frames a fresh start with the Bosmere F919 Pre-Formed Coco Liner. Crafted from natural coco fiber and pre-shaped for a confident fit, this liner creates a breathable, supportive home for roots and young plants while you relax into the growing season.

The built-in Soil Moist layer is designed to help keep soil moisture where it matters most. Moisture-retention means watering needs may decrease in hot spells, while roots stay hydrated during dry periods. This combination of air and water flow supports robust, well-structured root systems and healthy top growth.

Notable benefits at a glance

• Custom fit for 30-inch planters, delivering a secure, professional appearance
• Natural coco fiber construction promotes airflow around roots
• Soil Moist layer helps hold water in the soil longer
• Improves drainage and prevents soil from washing out
• Easy drop-in installation for quick planter refresh

Where you might use it is as versatile as your containers. Install the liner in window boxes along a sunlit railing, in traditional basket frames, or in decorative planter boxes that host flowering annuals, herbs, or trailing plants. The coco fiber supports plant structure by allowing air and water to move through the liner while giving roots the support they need to spread and grow.

Real-life use cases include creating a drought-tolerant summer display with trailing vines, or a fragrant herb window box that stays hydrated without constant attention. The liner’s breathable fabric helps with drainage and root health, while its pre-formed shape keeps the installation neat and tidy, restoring the professional look of your containers.

How to install and care

• Drop the pre-formed liner into your 30 in basket or window box frame
• Fill with soil and plant; ensure even distribution around the root zone
• Water as needed; Soil Moist helps retain moisture between waterings
• Inspect and refresh seasonally for best results

Environmentally friendly coco fiber is a renewable byproduct of coconuts, and the liner's pre-formed design minimizes trimming and adjustments, helping you get a clean look with less waste. The breathable material promotes aeration, reducing soil compaction and encouraging robust root exploration in containers.
