|Weed seeds need sunlight in order to sprout and grow. Weed block keeps most of the sunlight from penetrating the soil and that's what keeping the weeds from growing. Weed block also helps the soil warm up faster in the spring. However, it can also hold in heat which can stunt plant growth. Weed block can also keep fresh air from the soil, which can also affect plant growth. Hope this answers your question.
