Osmocote Exact High K 12-14M is perfect for pot plants needing high-potassium feeding for 12 to 14 months and compact growth (e.g., cyclamen, violets, primulas). Also suitable for herbaceous perennials and nitrogen-rich irrigation. When combined with Peters Professional water-soluble feeding, adjust rates based on water-soluble feeding levels.
