Pearl Oyster Mushroom Plug Spawn – Pleurotus ostreatus is probably the most common edible mushroom found on hardwoods. Growing on alder, cottonwood, poplar, oak, birch, beech, aspen and many other hardwoods, our aggressive strain is renowned for its productivity. Hardwood logs and stumps can be used for inoculation; after incubating the logs may be partially buried, horizontally-oriented, to conserve water during fruiting.
