Important: Always contact your ICL Specialty Fertilizers advisor for tailored advice for your nursery. Granules left on pavements can cause stains. Rates are based on average needs and pot volumes. Rates mixed in the freshly delivered growing medium can be higher in this case. Recommended application method is mixing. Plant-hole dibbling is NOT recommended. In case of pre-mixing in medium growing bunker, please consult your ICL Specialty Fertilizers advisor.
