For annual production outdoors, Cinderite is most effective when incorporated upon initial cultivation of the soil in the fall - minimal tillage/ one-time till is recommended.  Cinderite can be broadcasted or used as a top dressing at any time of the year.
For perennial production outdoors, Cinderite is best applied as a general top dressing in the fall. Acute treatment of disease in fruit cultivars may be accomplished at any time of the year by using the agglomerate as a rock mulch within the cultivar's dripline.
For container growing and succulents, Cinderite should be added to the soil matrix and applied as a rock mulch upon planting.
