Make Your Own Rabbit Manure Fertilizer


Though liquid fertilizers can be made from livestock manure, rabbit poop contains a great deal of nitrogen, which is ideal for fertilizing plants in your garden. The droppings are compact and do not smell quite as strong as livestock manure.


You Will Need:

  • 1 pound of rabbit manure
  • 1 ounce of unsulfured molasses
  • 5 gallons of water
  • 6 gallon bucket with lid
  • Nylon stocking or burlap sack
  • Strainer, cheesecloth, or fine sieve
  • Goggles for eye protection
  • Rubber gloves for skin protection
  • PreGro Plant Sprayer

Directions

When handling manure, always make sure to protect your eyes and skin. Put on your protective eyewear and rubber gloves. Then put the rabbit excrement into a nylon stocking or burlap sack, tying off the ends to make sure the droppings do not leak out. Put 1 ounce of unsulfured molasses into a 5-gallon bucket, then pour two and a half gallons of water into the bucket. Place the sack of rabbit manure into the bucket and secure the lid. Allow the droppings to steep in the liquid for 2 to 4 weeks, giving it ample time to ferment.

 

Once the fermenting period is over, put on your protective gear, open the bucket, and remove the nylon stocking or burlap sack. Use a strainer, cheesecloth, or fine sieve to make sure any solids that might be in the liquid are removed. Remove 9 ounces of this liquid rabbit manure fertilizer and combine with 9 ounces of fresh water, diluting the solution in a 1-to-1 ratio. Pour this solution 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:

Fish Emulsion Liquid Fertilizer


High in nitrogen, soluble phosphorus and potassium, fish emulsion is a great way to use inedible parts of freshly caught fish to feed your garden. Your fresh fish must first be composted.


You Will Need:

  • 1 pound fresh fish waste (inedible parts)
  • 2 pounds of leaves, straw or sawdust
  • 1 ounce of unsulfured molasses
  • 5 gallons of water
  • Qty. (2) 5 gallon buckets with lids
  • Nylon stocking or burlap sack
  • Strainer, cheesecloth, or fine sieve
  • Goggles for eye protection
  • Rubber gloves for skin protection
  • PreGro Plant Sprayer

Making the Compost

When handling compost, always make sure to protect your eyes and skin. Put on your protective eyewear and rubber gloves. Place your fish parts in a 5-gallon bucket then add leaves, straw, or sawdust. Add at least 1 ounce of unsulfured molasses to the bucket to help minimize odor. Secure the lid and let all these ingredients decompose for 2 weeks. Make sure to get your protective gear on every 2 days so you can open the bucket to stir the mixture. The compost needs to be aerated every 2 days; stirring will provide air circulation to support the composting process. After 2 weeks, your fish compost should be ready to be made into liquid fertilizer.

 

Making the Fish Emulsion Liquid Fertilizer

Put on your protective eyewear and rubber gloves. Then put the fish compost into a nylon stocking or burlap sack, tying off the ends to make sure the compost does not leak out. Put 1 ounce of unsulfured molasses into a 5-gallon bucket, then pour two and a half gallons of water into the bucket. Place the sack of fish compost into the bucket and secure the lid. Allow the droppings to steep in the liquid for 1 to 2 weeks, giving it ample time to ferment.

 

Once the fermenting period is over, put on your protective gear, open the bucket, and remove the nylon stocking or burlap sack. Use a strainer, cheesecloth, or fine sieve to make sure any solids that might be in the liquid are removed. Remove 9 ounces of this fish emulsion liquid fertilizer and combine with 9 ounces of fresh water, diluting the solution in a 1-to-1 ratio. Pour this solution 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.

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.

DIY Compost Tea Spray


Brewing compost tea is a great way to create a homemade liquid fertilizer that will provide your plants with vital nutrients and beneficial bacteria to help suppress fungal diseases and support seedling growth.


You Will Need:

  • 1 pound of mature compost
  • 2 tablespoons organic unsulfured molasses, no preservatives
  • 4 gallons of water
  • 5 gallon bucket
  • Nylon stocking
  • Rock or weight
  • Aquarium pump with 3 feet of aquarium hose and gang valve
  • Fine mesh strainer bag, strainer, cheesecloth, or fine sieve
  • Goggles for eye protection
  • Rubber gloves for skin protection
  • PreGro Plant Sprayer

Directions

When working with compost, always make sure to protect yourself. Put on your protective eyewear, rubber gloves to safeguard your skin, and a facemask for those concerned about inhaling potentially dangerous microbials. Dangerous bacteria, such as E. Coli. can exist in the raw ingredients of a compost pile, so make sure to use mature compost, which has a sweet, earthy smell. Put your pound of mature compost into a nylon stocking and tie off the end. Fill a 5 gallon bucket with 4 gallons of water and place the nylon stocking full of mature compost into the bucket of water. Use an aquarium pump with a 3 foot hose and a gang valve to aerate the liquid. The gang valve divides the flow of air into separate streams. Attach a rock or weight to the end of the aquarium hose so that it sits at the bottom of the bucket and pushes a good amount of air throughout the liquid. Add 2 tablespoons of organic, unsulfured molasses with no preservatives to the liquid. The beneficial organisms in the compost will feed off the molasses and release gasses, creating a bubbly foam on top of the liquid. Consider adding 1 tablespoon of organic liquid fish emulsion fertilizer and 1 tablespoon of liquid seaweed to the bucket to make your compost tea more powerful. Let the compost bubble and brew in your bucket for 24 to 30 hours. You will know the compost tea is finished when it is a dark brown liquid with a foamy, white, bubbly top and a strong yeast smell. Once the compost tea has been brewed, remove the aquarium hose to stop aeration. Strain the compost tea using a fine mesh strainer bag, cheesecloth, or fine sieve. All solids must be removed from your final compost tea in order to make the spray. Pour the strained liquid 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:

  • Spray your plants in the early morning or evening, so as not to burn the leaves during the heat of the day.
  • Test your homemade compost tea on a single plant to make sure the compost tea does not have adverse effects.
  • DO NOT spray compost tea to any vegetable within 3 weeks of its planned harvest date.
