Good point, Chris. Most professionals I've read from or talked to would say you should drill it with mycelium within one month. Some say 2 weeks, some say 3 weeks. I usually start before a month because it might take me a few weeks to finish those logs. Of course, if where you live it is solidly frozen for the whole time, you might be able to go longer than a month. I think that they say cut in the spring as the flow starts because that is when it has the most sugars in them that the mycelium can grow on. Of course, that's for full time mushroom farmers. Many of us have other things to do, kids, spouses, full time other work, friends, other hobbies, etc. Sometimes we can get it for free. Spring is my busiest part of the year, and I live in a mild winter area, so I am more likely to cut or drill in the winter.
