Changes to Pro-Mix BX

The original Pro-Mix BX no longer contains Mycorise and has been changed back to the black bags that they used a few years ago:

The Pro-Mix BX containing Mycorise now is considered a premium product that has 50% more Mycorise in it than before and costs about a dollar or two more per bale. The benefits of Mycorise is that it increases root development which, in turn, helps the plants fight transplant shock and get off to a better start.
