Gravel is a popular hardscaping tool that enhances the visual appeal of a yard and is easy to maintain. It is drought-tolerant, deters pests, and suppresses weed growth. However, sometimes weeds may still appear. Adding more gravel is a simple DIY solution to prevent weed growth.
Ensure that your gravel layer is at least 3 to 4 inches deep and evenly spread to prevent weeds from breaking through. Adding a thin layer of gravel annually can smother any weeds forming. Regularly raking the gravel can also disrupt weed growth by turning over the rocks.
What kind of gravel is best for weed prevention?
Pea gravel is a budget-friendly option that can help prevent weeds, but may get dislodged in high-traffic areas. Construction gravel is a stable ground coverage option that is cost-effective. Angular gravel like lava rock, brick chips, or crushed granite compact nicely and are ideal for preventing weed growth.
Additional gravel tips to prevent weed growth
Consider using landscaping fabric or crushed stone underneath the gravel for extra weed prevention. Ensure there is proper drainage and minimal watering in areas where gravel meets landscaping that requires watering. Adding polymeric sand to fill cracks between stones can further prevent weed growth in gravel areas.
