Our Playground Bark is excellent for play areas. Engineered and tested to handle falls this is the choice for creating a playground area. Other options include coarse sand for sand boxes and underneath above ground pools. We have pea gravel which works well around playground equipment that is out of the direct sun and is a low impact area. Our turf builder is typically used for hydroseeding grass but also works great for getting extra muddy and would work well in a ‘mud kitchen’. And if you’re looking to teach the kiddos gardening we sell a gardener’s a-b-c mix of organic soil and compost. Kindness Rocks Project? We sell river rock by the 5 gallon bucket too!
