- Proper Depth
- Having 8-12 inches of mulch depth will ensure a “bounce affect” when children fall on the surface. This details is one of the specs in the ASTM certification. (American Society for Testing Materials)
2. Chipped vs. Shredded
- A quality playground mulch will have a chipped consistency rather than shredded. This cuts down on splinters, and doesn’t stick to socks nearly as much.
3. Non-dyed Material
- Most mulch dyes are not very mouth and hair friendly. They might look pretty, but to a discerning 3 year old pallet, not so much.
