What People Say About Us

I decided to try out this soil last year after always using big name bag dirt (fox farm etc.) I was blown away! best soil i have used, incredible results and the customer service is probably the best i have come in contact with in a long time. If you are shopping around, looking at other brands etc. STOP SHOPPING AND BUY THIS SOIL.

In short, Bud is more passionate about his soil than anyone I’ve ever met!  His soil is the best quality and you barely have to water your plant when most soils barely absorb.  We talked for an hour with him as he explained his soil base and the best way for us to use it!  Hands down best soil and we will be life long friends and customers.

Love this place! Bud and his staff are excellent, knowledgeable, and ready to assist you in anyway possible. Bud takes pride in his business, as demonstrated through his blends. I use the fourway on my veggies and bud’s blend for my flowers; both remain happy and healthy throughout the season.

As a gardener who has been buying bulk soil for years, it is rare that some debris is not mixed in, and often that debris comes from compost. I’ve been through well over 10 yards this spring, and can’t report anything “at the bottoms of my piles”….I will continue to support NorCal in the future, and encourage those in Lake and Mendocino counties to do the same!
