The depth of your decomposed granite depends on its intended use, but around 3 to 4 inches is the most common depth. Driveways that need to support a lot of weight should be at a depth of no less than 6 inches. Walkways that won’t see a lot of weight but lots of foot traffic should be built at a depth of 3 to 4 inches, and patios should also be between 3 and 4 inches deep.

Seal bags firmly for materials like soil or mulch, store unused parts in dry and cool spaces to prevent decay and use material visually formed covers for extended periods.

Yes, weeds can still grow in decomposed granite. If properly compacted, it can act as a good weed suppressant, meaning you’ll only pull weeds occasionally.

Mulch costs anywhere from $30 to $150 per cubic yard, depending on several factors. On the lower end, common types like red and black mulch cost about $35 to $40 per cubic yard and are often made from recycled wood. More premium options like cedar, cypress, and rubber mulch can cost between $100 and $120 per cubic yard. The total cost is also influenced by delivery, which can be around $75 per cubic yard, though many companies provide a free estimate. It is generally cheaper to buy mulch in bulk and have it delivered, but buying it in bags may be more cost-effective for smaller areas. Other factors like the quantity you need, time of year, your geographical location, and professional installation will also affect the final price. Before getting quotes, it's a good idea to calculate how much mulch you need. A professional can help you determine the most suitable type for your landscaping needs.
