Osmocote Exact High K 8-9M is perfect for pot plants needing extended high-potassium feeding (8-9 months) and compact growth (e.g., cyclamen, violets, primulas). It's great for herbaceous perennials and nitrogen-rich irrigation. When combined with Peters Professional water-soluble feeding, adjust rates based on water-soluble feeding levels. Mix with Osmocote CalMag for added calcium and magnesium in soft water cultures or nitrogen-demanding early growth. For crops with high iron demand, use with Osmocote Iron. Achieve precisely the right nutrition for outstanding results.
