What Is Fish Fertilizer Good For?
Fish fertilizer (typically 5-1-1 for emulsion or 2-3-1 for hydrolyzed) is good for seedlings, transplants, container plants, and gentle all-purpose feeding. Its low concentration makes it nearly impossible to burn plants. Fish emulsion is heat-processed (cheaper, less complete). Hydrolyzed fish is cold-processed (retains more nutrients and beneficial compounds). Both are OMRI-listed organic options that feed soil biology alongside plants.
