Frequently Asked Questions

What are worm castings?

Worm castings are a nice way to say worm poop. Don’t worry, they’re odor-free! For the science nerds and those who want to know the technical info, worm castings are stabilized organic matter that are produced by the interaction of earthworms and microorganisms under controlled conditions.

How do worm castings make my plants or produce grow better?

Worm castings provide readily available nutrients plants need. Since worms do a majority of the processing, plants can easily and quickly absorb those nutrients and minerals. Worm castings are also full of elements that help fight plant diseases that can be caused by soil and soil deficiencies. They also repel other insects from wreaking havoc on your plants.

What’s the difference between chemical based fertilizers and using worm castings?

Chemical fertilizers are a short-term boost to plant’s growth, but after the initial growth the soil is left depleted and “addicted” for more chemicals. We even joke that worm castings are a rehab for soil because they restore living microorganisms that break down organic matter, providing it with the nutrition it needs to live. Worm castings show faster and stronger growth than plain soil, making plant health sustainable, not just pretty on the outside. 

Because the worms digest and break down organic materials to create the castings, they are in the perfect form to be used in your garden. They’re plant and soil ready without needing additional dilutions or solutions to make them useful in your garden.

Do I order worm castings separately from soil?

Our soils include worm castings. Our soil recipes and our custom blends are made of high quality, nutrient-rich compost and a specifically formulated combination of all-natural ingredients. 

Already have soil and want to add worm castings? Our worm castings, sold separately, can be added to any soil to aid healthy plant growth. 

You can order online here or visit us at an event or purchase from one of these locations!

Can I just add worms to my plants or garden?

As long as they’re regularly fed, yes.

To create your own version of a worm farm, we recommend our specially designed worm towers. Worm towers act as a tiny compost tunnel so you can start your own organic soil fertilizing right in your own backyard!

Great for gardens or spaces without room for a larger setup, we’ll guide you through how to correctly install and upkeep your worm towers.
