Not All Fish Emulsion Is The Same! I was surprised when I learned this. Fertilome Fish Emulsion is top quality plant food that will not burn your plants. But it still smells like fish emulsion. Formula analysis on fish emulsions will vary. Even more important is the nitrogen type in the fish emulsion. You can use fish emulsion for any growing plants. I have put it in a hose end sprayer and sprayed my lawn and garden with it in the early part of the season. My kids hated the smell but I told them to pretend they were at the beach. It has more nitrogen than I want to use later in the season, but the good news is that Fertilome fish emulsion is a slower release nitrogen. 1 Gallon jug.
