Whether you’re an admirer of flowers or a professional gardener, applying fish fertilizer is one of the best things you can do for your plants.
Seagate Fish Fertilizer Concentrate (FFC) is a fertilizer derived 100% from whole anchovies and sardines caught along the shores of Baja California. The highly concentrated powder is made from and is the equivalent of 16 pounds of whole fish. Fish is full of healthy nutrients and has been used as a fertilizer around the world for centuries. It’s ideal for giving flowers, trees, and vegetables an extra boost and provides long-lasting benefits for both indoor and outdoor plants.
Benefits of Fish Fertilizer
These are some of the many benefits of using fish fertilizer as an alternative to chemically produced products on your plants.
- It’s safe to use with kids and pets around
- Easy to apply both indoors and outdoors
- Lasts for up to 4-5 months between applications
- No other fertilizing products are necessary for most plants
- Prevents root-burn common to many chemical-based fertilizers
- Safe for edible fruits, vegetables, and herbs
- One container can fertilize hundreds of plants
Tips for Indoor Plants
When you apply our fish fertilizer on indoor plants, make sure it is applied below the surface unless you want your house to smell like fish. Pour a small amount of FFC into a small hole opened near the plant’s roots, and then completely cover the fertilizer with soil to prevent unwanted odors in your home.

Most indoor plants are relatively small, so you’ll only need one teaspoon of FFC for both existing plants and new plantings. Always make sure to water your plants right after feeding them with fertilizer to help stimulate the bacterial action.
When you choose to fertilize has a huge impact on the effectiveness of your fertilizing strategy. The faster plants grow the more fertilizer they will need, and nutrient needs change with different stages of plant growth. On average, one good application of the FFC will last 3-4 months.
Tips for Outdoor Plants
For outdoor gardens, it is also better to apply FFC beneath the surface because this is where the soil microbes will break it down. Odors may not be as big of a concern outdoors as they are indoors, but FFC is simply more effective when it reaches the roots.
It utilizes the slow bacterial decomposition of fish into its protein and mineral components to deliver those nutrients to the plants you love. If you are growing rose bushes, apply FFC one month prior to the first bloom each year.

Dogs and cats often love the smell of fish, so prevent your pets from getting into your fertilized plants by placing fertilizer under the soil’s surface. This is also a useful tactic to prevent raccoon, foxes, and unwelcome animals from entering your garden. Always wash your hands thoroughly after applying FFC to avoid odor and any potential irritations.
These are some of the many plants that really benefit from fish fertilizer usage.
So if you’re looking to feed your plants a steady diet of the key nutrients they need, then give FFC a try this season!
I have been trying to make my plants grow with lush green leaves and produce flowers. However, this does not happen always. My water jasmine is a mess and vellaris glabra does not flower well. Someone suggested using fish meal and I am a bit hesitant to use them because they can emit foul smell. If you could enlighten me on how to use this type of fertiliser and gibberalic acid, I shall be immensely grateful.

Hello Moosa,
I have been using the fish fertilizer in my own garden on everything – rose bushes, avocado trees, lemon trees, orange trees, sunflowers, misc. flowers, etc. In our company, we use the fish for fertilizing all of our crops – tomato, olive tree, pomegranate, broccoli … etc. We have been doing this both at home and commercially for ~30 years. As long as you bury the fish below the surface of the soil, you will not have a smell. This is also a more efficient way to use the fertilizer because it gives the soil bacteria a better chance to break down the fish, rather than leaving it on the surface in the air where it will just dry out and smell. Depending upon the size of the plants, you would add more or less. If buried correctly, it will usually last a few months as the soil bacteria slowly break it down into the basic nutrients. One thing to keep in mind is if you have any animals that like to dig things up, they likely will be attracted to the area where the fish is buried and will start digging holes to get at the fish. We use the fish as a stand-alone fertilizer, not requiring any additional sources of fertilizer.
