Osmocote Exact High K 5-6M is ideal for pot plants needing extended high-potassium feeding (5-6 months) and compact growth (e.g., cyclamen, violets, primulas). It suits herbaceous perennials and nitrogen-rich irrigation. When used with Peters Professional water-soluble feeding, adjust rates accordingly. Combine with Osmocote CalMag for added calcium and magnesium, suitable for soft water cultures or nitrogen-demanding early growth. For high iron-demanding crops, mix with Osmocote Iron.
