Worm Casting Tea Applications – Grow Green Naturally in your Garden

Worm Casting Tea Applications for naturally nourishing your garden.
Casting to Tea Mix Ratio Reference:
1 pound of Worm Casting makes 5 gallons of Worm Casting Tea.
3.2 oz of Worm Casting makes 1 gallon of Worm Casting Tea.

For General Applications follow amounts according to the size of area needing coverage.

*For Soil Drenching Apply 4 X the amounts shown according to size of area.

1 Acre 5 gallons (640 oz) of Worm Casting Tea (1 Acre = 43,560 sq ft, which is an area of 208.71 feet x 208.71 feet)
1/5th Acre 1 gallon (128 oz) of Worm Casting Tea (1/5th Acre = 8,712 sq ft, which is an area of 93.34 feet x 93.34 feet)
1/20th Acre 1 quart (32 oz) of Worm Casting Tea (1/20th Acre = 2178 sq ft, which is an area of 46.67 feet x 46.67 feet)  
1/40th Acre 1 Pint (16 oz) of Worm Casting Tea (1/40th Acre = 1089 sq ft, which is an area of 33 feet x 33 feet)
544.5 sq ft 1 Cup (8 oz)of Worm Casting Tea will cover (544.5 sq ft, which is an area of 23.33 feet x 23.33 feet)
68 sq ft 1 Ounce of Worm Casting Tea will cover (68 sq ft, which is an area 8.25 feet x 8.25 feet)

Special Notes: on Tea Amounts for 100 & 1000 sq ft. 14.69 oz of Worm Casting Tea used on 1000 sq ft. 1.5 oz of Worm Casting Tea used on 100 sq ft. Remember to follow your brewing instructions. It is best to always spray during early morning or late afternoon hours. You may need to see that your sprayer is calibrated to spray correctly or that if you are using showerhead or other type sprayer you get an idea of your application rate before hand.

Calibrating a showerhead type sprayers: Mark off an area 10 x 10 sq ft (10 x 10 – 100 sq ft) Fill your sprayer with water, then use your general application technique and walking speed to spray the marked off area. Be sure to pick your normal walking speed and pattern of spraying you plan to use during the entire time it will take to complete the actual area(s) you plan to spray. After spraying the marked off area calculate the amount of water to fill your sprayer back up. For example, if it takes .2 gallons. Then your application rate is .2 gallons per 100 sq ft. To get this to most standard used applications rate you would multiple the 100 sq ft and/or .2 gallons x 10 to reach the standard of 2 gallons per 1000 sq ft in coverage for larger area applications. Now based on the dilution rate noted earlier in this information if you plan to spray 1000 sq ft and you have concluded you spray about 2 gallons per 1000 sq ft. Then all you need to do is take the two gallons of dilution less say 15 oz of it and add in 14.69 (15oz) of Worm Casting Tea to make up your total 2 gallons you plan to spray on the 1000 sq ft area.

Calibrating a Boom Sprayer Fill sprayer with water, turn pump on desired pump pressure, hold container under one sprayer nozzle for 1 minute then measure the amount in the container. You will want to measure each nozzle to be sure each nozzle is putting out the correct amount. A standard rule of thumb is 10% < > variance between most nozzles would say a nozzle needed replacing. (consult your manufacturers specs for correct flow rate based on a given pressure) Add the amounts released from each nozzle together to give you the total gallon(s) per minute flow of your sprayer. Example: If your sprayer has 10 nozzles and each nozzle puts out .2 gallons per minute then the sprayers output is 2 gpm. The next step is to determine how much area your sprayer will cover in a given amount of time. This depends on travel speed and width of spray coverage. Get the spray width easily by turning on and off the sprayer and measuring the wet pattern width. Next measure your sprayers speed and coverage. Do this by running the sprayer at a fixed rpm or gear and measuring how far it travels in 1 minute. Let’s say your sprayer travels 100 feet in 1 minute. The spray width is 16 feet. You now multiple these two amounts 100 x 16 = 1600 sq ft per min you have for coverage. Now you will need to determine your sprayer’s application rate. You do this by dividing the output by the coverage. In our example here it would be 2 GPM divided by 1600 which is 1.25 gallons per 1000 square feet your sprayer is putting out. So if you plan to spray an acre which is roughly 43,000 sq ft you will need 43 x 1.25 gallons of liquid (43 x 1.25 gals = 53.75 total gallons of liquid to distribute it evenly across the acre. Now of that amount what is the label rate or in our case Worm Casting Tea for general application is 5 gallons per acre so you would need roughly 49 gallons of water mixed with 5 gallons of worm tea to make up your total liquid content of 53.75 gallons.

Getting Maximum Coverage and Benefit Let’s say you are spraying large shrubs. We recommend you spray the ground and the shrub on top and all sides when possible.

When to spray. Always spray early mornings or late afternoons unless you have a cloud covered day without much sunlight. You want the microbes to have a chance at adjusting and taking hold of their new environment. We suggest soil drenching a few days to a week before planting anything new or in any case of soil erosion, depletion and other negative impacted reasons you have experienced. You can dip your seeds in the worm casting tea the day you are soil drenching. This gives the soil and the seeds a worm casting tea inoculate right from the start. If you are transplanting you can dip and/or spray roots and tops day before transplanting and during transplanting as well. Spray Worm Casting Tea 1 week after planting or transplanting and then continue every 3-4 weeks throughout the growing season. (Get a spraying in during blooming)

Special Note: We have found using Worm Casting or Worm Casting Tea reduced the number of insects in our garden tremendously. After using it on our flowers, shrubbery and lawn we noticed fewer insects on or around them also. You get the picture; less insects outside ultimately means less insects getting inside your home. It is a win across the board.


General Noted Information Our Worm Casting Tea has animal manure that has been composted before reaching the worms. This allows the breaking down of bad pathogens if any before they reach the worms. Worms then compost and digest and mix it with other feed to make it a very rich natural soil full of nutrients and other plant ready food. There are some government officials that have stated that animal manure must be composted before feeding it to the worms unless your products are going to be represented and sold as compost and compost tea. Wiggle Farm Worm Casting or Worm Casting Tea is not compost or compost tea as all manure has been composted before being mixed with other feeds and fed to the our worms. We take all the steps we find necessary to make the final blend a very rich natural soil loaded with microbes and ready for all your growing needs in an all natural way.
