King Oyster (Eryngii) and casing for outdoor fruiting
    #6196104 - 10/21/06 11:10 PM (17 years, 3 months ago)

Well, I started myself up some king oysters using the LC direct to fruiting substrate in spawn bags procedure. The substrate this time is mostly alder sawdust (coarse) with 1% calcium carbonate flour, 2.5% WBS, and 2% brown rice protein powder (which is 80% protein). The final nitrogen is about 0.3% to 0.4% I compute which is pretty rich. Anyway, I'm only 24 hours post injection, and I can see the mycelium starting up already. I think it's going to finish really fast.

My question is if others have tried to use a casing on these? I know in nature that king oysters grow close to the wood-soil interface, and I'd like to try that. The reason is because I want to grow them outside rather than in a controlled setting using the bag sides to keep the moisture up. But even with the bag side up, the ambient humidity is pretty low. I figured the casing would help.

I've never tried oysters with a casing layer. I wonder if you could bury or partially bury the bags to simulate the soil/wood interface?

I don't think this applies to all oysters. I have only read oysters growing at the soil-wood interface in regard to the King Oyster. Most of the rest grow directly on the wood. What I am going to try is pasteurized, buffered Uni-Gro cactus mix, which is nutritive, at a thin layer of about 1/3rd inch and a pH of 7. I'll keep the bag flaps up to about 5 inches around the top of the surface and keep the bag outside but free from sun and wind. I'll do some of the other bags the traditional way in a humidity tent and see which works better.

I buried a straw block of ostreatus half of its size in my vegetable garden and covered the rest that was exposed to the air with translucent plastic bags. I watered the soil once in a while and mist the exposed straw twice daily and it worked. I know eryngii is not ostreatus but might work as well. Here are the pics:





You can see the bags that covered the straw and the stones that kept the bags in place, you know I live in a very windy location.

I have fruited Eryngii outside, dug a hole and burried the block in
the garden in a shady spot.

WOW! This is awesome, guys! Thanks for the pictures, Semilanceata! Your block is an inspiration. Maybe I'll try to bury the bag sort of then. At least I could bury the bag bottom just to keep it more temperature stable, even if it doesn't directly contact the dirt.

And falcon, you don't have a picture of that buried Eryngii do you? According to Paul Stamet's latest book Mycelium Running, Pleurotus Eryngii is naturally cultivated via buried logs and "does better in a terrestrial setting than do most species from the genus Pleurotus." There is also a picture showing it growing from carrot roots and breaking up through the ground! Despite all of this, I have not seen pictures of artificial cultivation close to the soil of this species, although I bet it would do well.

Nope, don't have a picture. There was a P. ostreatus block that was
burried at the same time as the eryngii and they fruited a couple of days
apart.

I've tried the exact same thing Bluehelix, with the exception they weren't King's. The Oyster mycelium simply colonized the casing layer completely, making it kind of useless for humidification. Maybe you'll have better luck than I did.
