Pond Boss Forums MANAGING AN EXISTING POND Fertilization Using old fertilizer

Completly disagree. I bought some old fertilizer from a client who did not want it. It was tough to get the stir it up, but I did and it worked just fine. It may not work quite as good, but I can not think of any negatives in trying to use it in your pond. Especailly useful in the early spring when trying to get the bloom started. LIke all liquid fertilizers dilute it down 4 to 1 before applying to the pond. My 2 cents.
