High K 3-4M

High K 3-4M

Boost potassium in your compact plants








Osmocote® Exact High K 3-4M is highly suitable for pot plants requiring high-potassium feeding over 3 to 4 months and where compact growth is important, such as cyclamen, violets and primulas. Also ideal for herbaceous perennials and for use in nitrogen-rich irrigation water. Osmocote® Exact High K works very well in combination with Peters® Professional water-soluble feeding. The recommended rates should be adapted, depending on the amount of water-soluble feeding. Can be used in combination with Osmocote® CalMag when an addition of calcium and magnesium is recommended (for example soft water cultures) or in cultures that demand more nitrogen during the first months of growth. And for crops with high iron demand, this product can be combined with Osmocote® Iron.
