A by-product of our mushroom growing is large amounts of spent growing blocks.

After a few harvests, these block are no longer viable in the grow room, however, they make excellent additions to compost piles! The blocks are made of sawdust and soybean hull that is consumed by mycelium and will accelerate the decomposition of your compost while adding beneficial microorganisms to your garden.

Our supply is available for FREE to our CSA members!

After our pile thaws in the spring/early summer, we'll send out an email with more details to our current (Summer) CSA members, as well as those from the previous Fall and Winter sessions.

Pickup & Composting: You'll need to load the blocks into your truck or trailer and each block has a plastic bag that need to be removed before composting, so it is a bit of work.

We do recommended composting the blocks for at least one year before adding them to your garden. First year blocks (not composted) will very likely overrun your garden with mushrooms - you could experiment with creating a dedicated garden bed of 'wild' gourmet mushrooms! Second year blocks will be fully decomposed.

Quantities: We are typically looking for people who can haul at least a pickup truck's worth or more.
