Osmocote CalMag


DUBLIN, Ohio – Calcium is essential for proper cell wall development in young plants, stems, terminal buds, bracts, flowers and fruit. Magnesium is a critical component of the chlorophyll molecule, the green pigment that creates energy for plants. Now, ICL Specialty Fertilizers’ Osmocote CalMag 9-0-0 blend is available to provide additional calcium and magnesium to plants that need it most. 

“Many plants exhibit calcium or magnesium deficiencies for a variety of reasons,” said Kurt Brace, ICL’s ornamental horticulture marketing manager for the Americas. “By simply adding Osmocote CalMag to their fertilizer programs, growers can provide these plants with a steady supply of calcium and magnesium over time. This practice can eliminate repeat applications, saving time, labor and money.” 

Osmocote CalMag is a blend of ICL’s patented E-Max polymer coated technology and micronutrients. It’s ideal for plants that require extra calcium and magnesium, as well as those grown in lower root zone pH levels; those irrigated with low alkalinity rain, surface or well water; or simply those plants tested and found to be deficient in these micronutrients. 

Growers can topdress Osmocote CalMag or incorporate it into growing media – a particularly wise practice when using lower lime rates. Plants should be watered immediately following an application of Osmocote CalMag. 

“Osmocote CalMag can be used in combination with ICL’s other Osmocote and Peters fertilizers,” Brace said. “By providing supplemental calcium and magnesium, Osmocote CalMag can help improve the overall health and appearance of potted plants, bedding plants, perennials, sub-tropicals and container nursery stock crops.”

Osmocote controlled release fertilizers have provided reliable, effective plant nutrition for over 50 years. To learn more about Osmocote CalMag 9-0-0, contact an ICL Territory Manager near you or view this comprehensive product information sheet.
