Comfrey Liquid Fertilizer Tea


Comfrey contains three key plant nutrients – nitrogen, phosphorus, and potassium – making it an ideal ingredient for liquid fertilizer tea. Before making the comfrey liquid fertilizer tea, prepare your materials.


You Will Need:

  • Leaves from a Comfrey plant
  • 1 ounce of water
  • 1 plastic water bottle
  • 1-gallon pitcher
  • Measuring cup (ounces)
  • Strainer, cheesecloth, or fine sieve
  • Goggles for eye protection
  • Rubber gloves for skin protection
  • pH Test Kit
  • PreGro Plant Sprayer

Directions

Begin by drilling a very small hole in the bottle cap of a plastic water bottle. Because comfrey leaves can be irritating to the skin, it is important to wear long sleeves and gloves when handling this plant material. Put on your protective eyewear and rubber gloves. Pour 1 ounce of water into your plastic bottle then shove the comfrey leaves into the bottle. Screw the cap onto the bottle and turn the bottle upside down into a gallon-sized pitcher. Leave the plastic bottle to drip into the pitcher for 3 weeks. After 3 weeks, the gallon-sized pitcher will contain a highly-concentrated and extremely smelly dark liquid. Put on your protective gear once again and dilute the brown liquid by pouring in 15 times as much water. For example, if you get 3 ounces of comfrey concentrate, add 45 oz. of water (roughly 3 pints) for proper dilution. Strain the solution of all solids using a strainer, cheesecloth, or fine sieve. All solids must be removed from your final fertilizer tea. Use a pH test kit to make sure the acidity levels are between 6 and 6.5. If the tea is too acidic, you can dissolve a sprinkle of baking soda in the liquid to lower the acidity. If the tea is too alkaline, you can add one or two drops of vinegar to increase the acidity. Pour the final fertilizer tea into the easy-to-fill glass container. Never shake the PreGro Plant Sprayer when the glass container is attached to the sprayer. The PreGro Plant Sprayer utilizes aerosol technology, but does not contain CFCs. For optimal spray, hold sprayer between a 90 degree angle and a 45 degree angle.

 

Important Tips:

  • Test your homemade liquid fertilizer on a single plant to make sure the solution does not have adverse effects.
  • Spray your plants in the early morning or evening, spraying the underside of the leaves and near the base of the plant.
