Total Lawn is a natural liquid lawn fertilizer made from North Atlantic fish — a rich source of nitrogen plus the amino acids and micronutrients synthetic fertilizers leave out. Our low-heat process protects the nutrients that get cooked off in conventional fish emulsions, so more of it reaches your roots. The result is steady green growth and stronger root systems without burn, runoff, or the boom-and-bust cycle of synthetic quick-release products. 2-4-1 NPK.
