Safety Concerns

Chemical Composition of Weed Block

Weed block, also known as landscape fabric, is typically made from synthetic materials such as polypropylene or polyester. These materials are designed to be durable and provide effective weed control by blocking sunlight and preventing weeds from germinating. However, some weed blocks may contain chemicals or additives that could potentially leach into the soil and affect the growth of vegetables in the garden.

Potential Risks to Vegetable Plants

One of the main concerns regarding the safety of using weed block in vegetable gardens is the potential risk of chemical exposure to plants.
