How to Use Poo Pourri?

You can use Poo Pourri immediately, use it throughout the gardening season or store it for up to a year. Poo Pourri can be directly mixed with your potting soil or garden soil as an organic fertilizer. or used as a top dressing for your indoor or outdoor plants.  In pots and containers, don’t use pure Poo Pourri. Mix a ratio of 1:4 Poo Pourri to potting soil.  You can also use Poo Pourri to make “worm tea” liquid fertilizer to sprinkle near the roots of plants. See Poo Tea.

In the spring and prior to planting or as soon as the ground becomes workable mix 1”- 4” of Earthworm Castings (Poo Pourri) into the top 4” – 6” of soil and water in.

Add 1-part Earthworm Castings (Poo Pourri) with 2-parts of your favorite (fertilizer-free) peat or coconut coir based seed starting mix.

Annuals, Vegetables, or Perennials:

Seeding: Line seeding trench, hole, or bed.

Transplanting: Dig a hole, fill with ½ – 1 cup Earthworm Castings (Poo Pourri), then dig hole in the Poo Pourri. The idea is to let the roots grow down into the Poo Pourri, but also let them grow through the mix as they grow outward.

Potted Plants:

Apply 1 tablespoon for each 2 – 3” inches of pot diameter, gently work into soil, and water well.

DIY Potting Soil:

1 part worm castings

1 part coco-coir

1 part vermiculite or sand

Add your favorite supplements like kelp, Azomite etc.

Applying to Mulch:

Too inoculate and increase nutrient cycling ability of mulch, apply ¼” – ½” Earthworm Castings (Poo Pourri) and cover with the mulch. Water in both the mulch and Poo Pourri.

Compost Inoculation:

For a diverse biology that will accelerate the composting process, broadcast Earthworm Castings (Poo Pourri) between each layer of compost and lightly water-in.  

Store in dark, cool place — keep in a breathable container where the vermicompost won’t dry out. The active microbes will live for up to a year.
