Before you add something to your soil,
know what you're buying.
Meet Soily.
A vermicompost and biochar blend for houseplants, containers, and garden soil.
An amendment for the mix you already use.
Worm-worked compost, blended with biochar.
Together in one bag, in the quantity that fits your project.
Our process starts with aged compost.
It's watered and turned.
This is real footage from that preparation.
Then the worms get to work.
You're seeing the worm stage of our process.
The two are already blended,
so you can add Soily to the soil or growing mix you already use.
Choose two-and-a-half, five, or ten pounds.
We're thirty percent off, with five pounds at twenty-seven dollars and thirty cents.

FROM BAG TO YOUR SOIL
Made to be added.
Add Soily as an amendment alongside a suitable growing medium. It is not a complete potting mix. Choose your application before choosing the amount.
One blend. Your choice of bag.
2.5 lb is our smallest bag. Choose 5 lb for more material, or 10 lb when your project calls for it. Each contains the same blend, sold by net weight.

Ask about your project
Care starts long before the bag.
A little more patience.
A lot more intention.
We start with manure, sawdust and aged wood chips. Turned and aged over multiple years, then worked by red wigglers with selected additions and biochar. We bag the finished blend for each order.
Inside Soily
Compost first.
Worms second.
From aged compost to vermicompost rich in worm-worked material, including worm castings and biochar. Bagged for each order.
01 Give it time.
Manure and carbon-rich materials are blended, turned and aged over multiple years. Only then does the finished compost reach our worms.
02 Choose the inputs.
We blend in measured additions, including alfalfa meal and biochar, before feeding the compost to the worms. No yard waste or food scraps.
03 Let the worms work.
Red wigglers are natural composting specialists: they live near the surface and feed on decaying organic matter. That makes them well suited to our compost-fed beds, where they help turn aged material into vermicompost. Tens of thousands live in our wedge beds beneath a three-seed cover mix.
04 Know your blend.
The finished vermicompost contains worm castings and other worm-worked organic matter, with biochar included. Use it as a soil amendment alongside your growing medium.
05 Bag it for your order.
We fill each bag directly from our finished pile as we prepare your order for dispatch. This limits time in the shipping bag.
Good questions
A few things
worth knowing.
How does the fall sale work?
30% off applies automatically at checkout. Free standard shipping on orders containing only 2.5 lb and 5 lb bags, within the contiguous US + DC. Orders including a 10 lb bag have shipping calculated at checkout. Tax is additional. Other discounts do not stack. Dispatch is when your order leaves us; carrier delivery follows.
Are worm castings and vermicompost the same thing?
Gardeners often use both names for worm compost. More precisely, castings are what worms excrete; vermicompost includes castings and other decomposed organic matter from the worm system. Soily is a vermicompost blend with biochar.
Why do you age the compost first?
Composting is the first stage of our process. We turn and age the manure and carbon-rich materials for multiple years, then feed the finished compost to worms. Those years refer to compost preparation, not time spent in the worm beds.
Do you use yard waste or food scraps?
No. Our process starts with manure, sawdust and aged wood chips, followed by measured additions to the worm feed. We do not use yard waste or food scraps.
Why plant the worm beds?
Living roots release carbon compounds that feed microbes around them. We plant a three-seed cover mix in our worm beds to bring living roots into the system. This describes our growing practice, rather than a measured nutrient claim for the finished bag.
What is biochar?
Biochar is a porous, carbon-rich material used in soil. It is one part of our vermicompost blend.
What makes Soily a premium blend?
Years of compost preparation, selected worm feed, planted red wiggler beds and biochar are part of our process. Each bag is filled per order from our finished pile. The value is in the ingredients, preparation and handling.
How do bagging and storage affect the microbes?
Worm compost is biologically active, and moisture and temperature affect its microorganisms. We bag per order to limit time in the shipping bag. After delivery, keep it cool and shaded, use it promptly and avoid complete drying. Bagging alone does not guarantee a particular microbial count.
What sizes can I choose?
2.5, 5, and 10 lb bags. The same blend in each size. Free standard shipping on orders containing only 2.5 lb and 5 lb bags. Contiguous US and DC only; tax is additional. 10 lb shipping is calculated at checkout. Contiguous US and DC only; tax is additional.
Can I pick up an order?
Soily Co. ships orders to the destinations available at checkout. Local pickup is not offered.
