Directions

consult rate tables printed on bag
verify product analysis, longevity and rate for plants in your production system (for assistance, contact your regional ICL-SF Territory Manager or call the ICL Lab at 877-467-8522)
fill tank with water to approximately 1/3 of full volume (use warm water if possible, to dissolve the fertilizer faster)

add STEM and mix vigorously
top off tank with water
a product trial is recommended before adopting a new fertilizer program or making full-scale changes to standard cultural practices (test several rates on representative plant types)
