Things You'll Need:
- Spray bottle
- Pump sprayer
- Hose attachment
-
Step 1
Decide on a method to apply the liquid fish fertilizer. There are methods to choose from including: a hand-held spray bottle, industrial-sized pump sprayer and a smaller garden hose bottle attachment. Any of these methods works well.
-
Step 2
Mix the fish fertilizer with water according to the directions on the package. Because liquid fish fertilizer comes in different concentration levels, it's important to mix it with the appropriate ratio of water recommended by the manufacturer.
-
Step 3
Apply the liquid fertilizer early in the morning or late at night to allow the plant to absorb the liquid. Do not apply it the middle of the day as most of the liquid will evaporate because of the heat of the sun.
-
Step 4
Apply the fertilizer directly to the soil at the base of the plant. Water until the ground is thoroughly soaked. Then spray the fertilizer onto the stem and leaves of the plant.
