How to Make Liquid Fertilizer for Grass


Liquid fertilizer is an easy, quick way to add nutrients to your lawn. The spray benefits the soil immediately because the liquid starts to soak into the ground within minutes of being applied. This improvement to the earth feeds the grass through the roots over time. Unlike granules, liquid fertilizers also stick to the blades of grass and are absorbed into the plant surface, feeding them directly. They can also be easily mixed together so that you can spread various nutrients in one application instead of separately.

Basic Fertilizer

Step 1

Pour into a spray container 2 tablespoons of Epsom salts and 2 tablespoons of ammonia.

Step 2

Add to the container 4 gallons of water.

Step 3

Put the lid on the container and shake it well to mix it all together.

Step 4

Spray the lawn with the mixture. It should cover 800 square feet of yard.

Seaweed Tea

Step 1

Fill a large trash can with water.

Step 2

Add seaweed to the water. Use at least three large bags full.

Step 3

Immerse the seaweed in the water completely, and put the lid on the can.

Step 4

Wait for at least two months. You will know it is ready when the seaweed is completely broken down.

Step 5

Mix one part fertilizer to one part water in a watering can or sprayer to feed the garden.
