EarthBox 81123 Original Mulch Cover Kit (2 Pack), Red

One of the key secrets to the EarthBox container gardening success is the EarthBox Mulch Cover. In addition to keeping unwanted weeds out, the EarthBox Mulch Cover helps conserve water and keep nutrients in, all while insulating the system and protecting its environment. Made from durable agricultural film, it's one of the most important elements of the EarthBox gardening system and should be used with each growing season. Depending on the climate and which color is face up, the mulch cover helps to attract or reflect sunlight. This assists in controlling the temperature of the growing media. Use the white side up in climates with sustained temperatures over 85 Degree F climates to prevent young seedlings from dying; or in contrast, in cooler climates, use the black side up to help warm the soil to stimulate growth. In some studies, red mulch covers have been shown to increase tomato and strawberry production by 12-20%. The red mulch cover reflects sunlight rays to the plant, in turn speeding up the growing process. Once in use, all mulch covers last an entire growing season. Each mulch cover is sized according to the growing system.
