What Our Customers Are Saying...

  • ★★★★★
    I’ve tried so many composts, but nothing compares to this. My heavy clay soil used to repel water—now it holds moisture beautifully and is full of life. I’ve even noticed more worms showing up!
    — Daniela S., San Ramon, CA
  • ★★★★★
    As soon as I spread it, I knew this compost was different. The texture, the smell—everything screams high quality. My plants have taken off, and my raised beds have never looked better.
    — Eli K., Oakland, CA
  • ★★★★★
    I added this to a struggling flower bed, and within weeks, the transformation was obvious—better color, stronger stems, and visible new growth. It's now my go-to for every planting project.
    — Matt B., Dublin, CA
  • ★★★★★
    I love knowing this was made in small batches with care. There’s real biology in here—mycorrhizae, beneficial microbes, everything your soil needs to thrive. Worth every penny.
    — Sophia R., Berkeley, CA
  • ★★★★★
    I’ve never seen so many earthworms so quickly. This compost doesn’t just feed the plants—it feeds the soil. It brought my tired backyard beds back to life.
    — Jake L., Livermore, CA
  • ★★★★★
    My garden soil is dense and silty, and I’ve struggled with drainage for years. After adding just one layer of this compost, the difference was immediate. Water now absorbs evenly, and my veggies are thriving.
