Fantang 4-Pack 30-Inch Rectangle Window Box Liners – Black Felt Planter Basket Liners

Overview

Fantang presents a practical 4-pack of 30-inch rectangle window box liners crafted from durable non-woven felt in a sleek black finish. Each liner measures approximately 30 inches in length and 7.5 inches in depth, designed to fit rectangle window boxes, wall baskets, fence planters, and similar containers. The liners sit inside to form a stable inner lining that helps plants breathe while keeping soil contained, even in windy outdoor spots or busy patios.

Why choose a felt liner

The breathable, moisture-retentive fabric creates a microclimate that helps keep soil evenly moist while allowing airflow to reach the roots. This balance can support healthier root growth and help extend the life of your planters by reducing direct soil contact with the basket material. The material is thick enough to prevent soil from leaking through while still offering air exchange essential for many plants.

• Non-woven felt with enhanced air flow and moisture control
• Deep 7.5 inch profile accommodates shallow-rooted plants and seasonal greens
• Thick fabric minimizes soil loss and spills from the container
• Bird nesting prevention: helps deter birds from using the liner as nesting material
• Easy to install: unfold, place inside your basket, fill with soil and plants
• Suitable for indoor and outdoor use, ideal for patios, balconies, fences, and walls

Versatile uses and settings

These liners are designed to fit a range of container setups including wall hanging baskets, window boxes, garden fences, rails, and wire plant holders. Use them with shallow-rooted herbs, leafy greens, flowering annuals, or compact ornamentals for a tidy, uniform look. They also serve as an attractive, low-maintenance option for cafes, shops, weddings, and other green spaces.

Note: outcomes depend on plant choice, climate, and care. The liners are designed to complement your planter and soil mix, offering a dependable, easy-to-use alternative to natural coco liners without making guarantees about growth results.
