What is the least expensive ground cover?
There are a few different types of ground cover that can be used for landscaping, and the least expensive option is usually mulch. Mulch can be made from a variety of materials, such as wood chips, leaves, or straw, and it helps to keep the soil moist and prevents weeds from growing. Another option is to use gravel or stones, which is a more durable option but also more expensive. If you're looking for something that's cheap and easy to maintain, mulch is the best option.
