How to prevent weeds in your garden with this unexpected bathroom item

How old shower curtains can help reduce weed growth

• Putting a shower curtain to work in a flower bed is fairly straightforward. The easiest approach is to install it before any planting takes place. Once the soil has been prepared, the curtain can be spread across the surface and trimmed to fit the shape of the bed.
• Openings are then cut wherever flowers, shrubs or other ornamental plants are intended to grow. The cuts only need to be large enough for the root ball and stem, helping to keep as much soil covered as possible. This leaves fewer opportunities for weed seeds to establish themselves between plants.
• After planting, the curtain should be concealed beneath a layer of mulch, decorative gravel or small stones. Apart from improving the appearance of the bed, the covering helps hold the material in place, slows moisture loss from the soil and provides an additional obstacle for weeds attempting to emerge.
• Before using a discarded shower curtain outdoors, it is worth cleaning and drying it thoroughly. Curtains that have spent months in a damp bathroom can harbour mould or mildew, neither of which is something gardeners want to introduce into freshly prepared soil.
• The method works best in newly created beds, where the barrier can be installed in one continuous sheet. Existing flower borders are often more difficult to cover because established plants and roots leave less room to position the material effectively.

How an old shower curtain can help control weeds before planting

• Rather than leaving the material permanently beneath a flower bed, they temporarily spread it across an area of bare soil during hot weather. This technique, known as soil solarisation, traps heat beneath the plastic and gradually raises soil temperatures.
• When conditions are favourable, prolonged exposure to heat can reduce weed populations and suppress certain soil-borne pests or diseases. The process typically requires several weeks and works best during the warmest part of the year.
• Solarisation is usually carried out before planting begins. Because the heat affects a wide range of organisms beneath the plastic, it is generally used when preparing a new bed rather than around established flowers.
