Soil Booster versus Soil Rejuvenate? I poked around online a bit (off your site) and didn't really find a clear answer What's the difference between these two products in terms of their intended use?
I've updated both product pages with the labels and a bit more information.
The Soil Booster is a more complete product for general usage. The Rejuvenate isn't as nutrient rich and is targeted at new plantings and trees under stress.
