I absolutely love the new store!
This has been my go-to home garden fertilizer place for a very long time and the friendly people help me with all soil and plant questions.
I would not go anywhere else for serious home and small farm plant growing needs.
Keep it up, Concentrates NW folks!

Wow! What a great store. My farm has been purchasing feed and soil supplies at Concentrates since 2005. They have such a great staff, good prices and valuable selection. Appreciate the superior customer support over the years.
Congratulations on the new showroom!

This is the only place around that I could find large bags of vermiculite. It’s totally worth the hour drive!
