The place where we get the spawn made the recommendation for type of tree to use.
www.fieldforest.net
We live in a very well shaded woods so we were able to harvest fresh logs of the recommended species, and our inoculated logs lay out in the woods.
Its almost essential that they be close enough to a water source....we lay a soaker hose across the logs and let it spray a gentle all day mist on them............(when we think of it----It should be once a week----we have not been as faithful as we should have been).
Now thay we've started the soft maple wood chip bed------in a spot that is more visable from the house...I hope we'll be more consistent with the watering.
Our neighbor, lacking natural shade, placed their logs inside a pole building.
They had little success-------'cause when they forgot to water------the logs really dried out---as compared to with our logs in the woods -----when I forget to water, the logs still recieve moisture from natural rainfall-------and they also lay on the natural forest floor with all its dampness, rather than on a sandy dry floor of a pole shed.
It continues to be an adventure of sorts.
