How can I line a window box without using coconut fiber?

The birds picked at the loose coconut fibers and the rest molded. Looking for a substitute for coconut fiber. Moss Maybe?

    It sounds as if your window box did not have enough drainage. All plant matter will eventually turn to soil, but if it's too damp and doesn't compost quickly, it will likely get mold, mildew, fungi, or worms. In a window box, too much rain without good drainage will result in water bound plants and moldy coconut fiber, or moss, mulch, pine straw, or anything else natural.
    So, increase the drainage in the window box, have a thick layer of lining, and make a simple awning above the box and flowers. Best wishes 😇

    I once read that burlap is very suitable as an alternative liner (especially compared to plastic based liners) as it allows proper drainage and is biodegradable, which additionally feeds the plants over time. To prevent mold, proper drainage is very important. All the best :)

    Birds are going to eat anything available.Line your window boxes with a sheer landscape fabric.This way the water will still drain.

    Increase the drainage. Line the box with a double layer of burlap. Then use the moisture absorbing stuff from the inside of a disposable diaper to your soil. Your plant roots will have the moisture they need without the standing water at the bottom that kills them And rots your liner. Burlap will rot, but is much nicer than the coconut fiber.
