I haven’t planted anything in the straw bales yet, but something is growing! I have a big crop of mushrooms in one bale and a smaller crop of grass popping out of some of the other bales. Both of these are expected events, though still a bit surprising. The mushrooms are “inky cap mushrooms,” which are mushrooms that dissolve into a black goo after a day or so — I noticed the goo pretty heavily on one of the bales.
Cornell University’s mushroom blog has an interesting post on inky caps and their tendency to destroy themselves. In addition to sprouting mushrooms and grass, the bales are definitely heating up and I expect to be planting them out within a week or so.
