There are often $10/yard mulch sales from Living Earth (normally $28/yd) for as much as you can haul usually 2 times a year. Check out Randy Lemmon's website. He usually posts about it on there. There is a Living Earth close to you in New Caney. They might not have another sale until Fall. IDK when you plan to do the project but contact Living Earth and see what they can do for your church project?
