CalMag

This innovative product has an abundance of calcium, magnesium, and nitrogen, all rolled into one fully coated controlled-release fertilizer. It’s just the thing for soft water irrigation systems, where plants so often crave extra calcium. Osmocote® CalMag gives them a daily helping of calcium, plus some extra nitrogen for the first few months of the growing cycle, just when plants like perennials need it. It’s easy to use, versatile, safe, and so effective – and great value too. Perfect for potted or bedding plants, perennials, and container nursery stock. Plus it’s especially good in peat-reduced growing media such as substrates with wood fiber, bark, cocopeat, or compost. Lower emissions of nutrients, in comparison to water-soluble calcium nitrate. Also works wonders combined with other Osmocote® products and water-soluble fertilizers, to get just the mix you need.
