How To Make Natural Rocket Fuel For Plants


If you want to boost your sweet plants giving them a real fastest growing, you can try this homemade fish emulsion fertilizer. Maybe, it is just what they need to get a more sophisticated upright growth.

The best thing about it is its organic nature, which means that it is ‘brim-full’ with nutrients to supercharge vegetal growth, and to act as a pest repellent at the same time! To find out how to make this “rocket fuel” read the lines below…

Homemade Fish Emulsion Fertilizer

You may find the extraction of the fish emulsion the most tedious part in making homemade fish emulsion, but it is worth the effort. Once you get the fish emulsion stored in bottles, it is a piece of cake to use it in your garden. The fish emulsion contains oil, so it is thick and viscous, resembling dense syrup. Make sure to shake the bottle before using to even the texture.

Note: 1 liter of this concentrated liquid fish emulsion goes a long way. A tablespoon of the fish emulsion should be diluted in a gallon of water (around 4 liters), and with this diluted mixture you water your garden plants. Never pour concentrated fish emulsion directly onto your plants.

Ways to apply your homemade fish emulsion fertilizer

There are two smart ways to apply the liquid fish emulsion:

1. The first is to water directly the base of the plant for best root uptake.
2. The second is by foliar spraying of the leaves.

The procedure given below outlines the first way – watering the plant roots. I chose this one for it is more effective and reduces fertilizer wastage. But because a ‘water runoff’ can happen while watering the ground, I use a funnel applicator to ensure focused application of fertilizer to garden plants. The simple use of the fish fertilizer may vary from once every 2 weeks to once every month.

You need these materials:

  • liquid fish emulsion
  • plastic spoon
  • funnel applicator (cut top half of a used soda pop bottle)
  • a watering can (without the sprinkler cap)

This is the application procedure:

First prepare the fish emulsion fertilizer for watering in this way:

  • The ratio of dilution is 1 tablespoon of fish emulsion to 1 gallon of water.
  • Carefully pour the fish emulsion into a tablespoon. Because of its oily content, homemade fish emulsion has the consistency of heavy syrup.
  • Pour the tablespoon’s contents inside the watering can.
  • The fish emulsion will get sticking on the spoon, so flush it with a garden hose.
  • Continue filling up the watering can with the garden hose at high pressure until you get the correct dilution ratio.

You will notice rich foaming on the surface of the water. This is due to the nutrient-rich fish oil in the fertilizer.

Next, prepare the funnel applicator and the watering hole like this:

  1. Cut off the top half of an empty soda pop bottle and remove the cap as shown in the picture below. This will allow you to funnel all the liquid fish emulsion fertilizer into the ground where the plant’s root area is.
  1. To create the watering hole, 3 inches deep below the ground jab a thick stick or a metal rod, or where you intend to water. Below is the one I used. In fact it is the same metal rod I use to manually till the soil.
  2. Create a conical hole on the ground with an encircling motion, as seen below:
  3. This conical watering hole has 2 purposes: one is to center the watering in the root zone and not cause spillage or runoff, and the other is to keep the funnel applicator stable and not allow it to topple over when you start watering. The finished conical hole should look like this one right below:

Finally, swiftly apply the fish emulsion with the watering can 

  • Press and position the funnel applicator into the conical hole and keep it steady.
  • Gently bucket the fish emulsion fertilizer into the funnel with the watering can (remove the sprinkler cap beforehand), as seen below:

Note: If the planting soil is slow draining, make a few more holes in the ground for nearby plants while waiting for the ground to absorb the fish emulsion fertilizer. Repeat the previous 2 phases for applying the fish emulsion fertilizer to other garden plants in need.

How to use the leftover fish emulsion pulp

When you extracted the liquid fish emulsion there was a leftover fish emulsion pulp in the basin, right? I hope I am not late to say: Do not throw it away! The leftover pulp is nutrient-rich and may be of great help to your garden’s soil.

All you need to do is evenly spread it out and mix it in your soil, as it is quite concentrated. Afterwards, don’t forget to water plentifully!

I also heartily recommend another use of the surplus fish emulsion pulp, which is return all of it in the 5-gallon bucket. This can become a quick “starter culture” for your next batch of fish scraps or wastes.

The leftover fish emulsion pulp already has plenty of active microbes in it, so the remaining amount of molasses in the pulp will now help expedite the decomposition of the second batch of fresh raw fish scraps.

This one is a definite bonus of this practical garden fertilizer:

Due to its rapid decomposition, the second batch of fish emulsion will not smell as bad as when you started from scratch with the first one. The second batch’s fishy odor in the first week of processing will definitely be more tolerable.

Hopefully, your family will have understanding for your willing to have the best-looking garden in the vicinity! If not, go to the local farmer’s market and buy a ready-made odorless fertilizer. If you can smell it, they can sell it, right?
