Where Can I Find Triple Ground Mulch?

Q: Where do I find triple ground mulch like I used in Pennsylvania? It looks great and it works wonders under shrubs.

A: Due to shipping costs, mulch is usually generated from local sources. Triple ground bark mulch might be common up North for the same reason that pine straw and pine bark chips are readily available here. Some of the local bulk landscape supply places sell a double ground bark material which might be workable for you but it might be a bit too coarse. Almost all stock a product called aged pine fines. It is pine bark that’s been ground and screened to have particle sizes less than 1/4”. I’ve seen the same ground pine bark sold as “bark mulch” in bags at local nurseries. Look around for split bags to see if what’s inside will work for you.
