Had to take down some top-damaged red oaks. Spring is a great time to innoculate stumps or logs with wood-loving fungus mycelium "plugs" availabe online or at local sources. 20-30 bucks gets you 100 plugs.(Edit- 200 plugs, enough for 8 3' by 4" logs) I jammed these oyster mushroom plugs in a few shallow chainsaw cuts, and hammered wedgeshaped pieces in behind. - this isn't the recommended way, but I had to get them going because the plugs were growing mycelia so fast. Luckily, this oyster strain is an agressive, local one that should do well. Oysters are the easiest to grow, by the way. These Maitake or Hen of the woods plugs are more finicky. Buy from a reputable source, as some strains reportedly will not fruit well. Due to our repeated freezings, that do not look to end soon, I brought two big log sections inside after soaking to give them a warmer head start.I used 3/8" drill bit (5/16 is better) sank into the sap wood about 1/2 inch in a ring shape, tap in with mallet and seal with food-grade wax beeswax or cheesewax. Decided to play a joke on the wife and dollied them in front of the dryer just for kicks . I will bury these 1/2 way down in a damp, shady area with nice loamy soil as "artificial stumps". Where I cut the trees is probably going to be to dry and sunny anyway. These 2 took about 70 plugs each, ( I put 2 in some holes i over-drilled, as well as a diamond pattern down the sides.) .I''ll do a third, smaller one later this week for my school's courtyard. I also did some shitake logs I will bury 1/3 in sand in a shady location I can get to easily with a garden hose. When I see a few start to fruit, i will soak in the stream overnight and the'll fruit like this one from several years ago.
