Aged & fresh

High-quality compost

Our compost, commonly known as mushroom soil, is steam sterilized to eliminate most weed seeds, making it a clean and effective option for improving your soil. This nutrient-rich compost is formulated from a blend of animal manure, mulched hay, and crushed corn cobs, then steam-sterilized to produce a high-fertility product that’s safe and gentle enough for most gardening needs. With excellent water retention and plant nutrient content, mushroom compost is ideal for enriching, conditioning, mulching, and balancing all types of soil.

We proudly offer both fresh and aged compost options—aged compost is about 6–9 months old, while fresh is straight out of the mushroom house—giving you the flexibility to choose the best fit for your garden or landscape project. Whether you’re a homeowner or contractor, you can count on us for high-quality, nutrient-dense compost delivered right where you need it.
