Perhaps buoyed by the unexpected success of my previous garden experiment, I’ve started another. This time, I’m trying to cultivate the wine cap (aka Stropharia) mushrooms in my garden. The wine caps are about the simplest of any to grow, which seems like a good fit for me since I’ve only had mixed success with growing shitakes in the past.
There are a handful of sites providing instructions on how to grow wine caps (links provided below), all of which were so short that I felt they were leaving out important information. But they weren’t leaving information out—it’s just that simple. I got my spawn from Field and Forest Products, a company out of northern Wisconsin.
The mushroom grows well in part sun to light shade, so I picked an area in prairie garden underneath a red maple tree. This area is full sun this time of year (i.e., before the leaves come out) but then is lightly shaded during the summer. Possibly because of the shade, few plants seem to creep into this area and it stays pretty clean with only mulch and minimal weeding. It’s also not far out the back door of our house, which makes it a good place to grow edibles.
I raked up the mulch, moving it just slightly to try to smother out some grass on our septic lawn. (I try to kill the lawn whenever I can.) Then I covered the area with about 1 inch of straw. Based on the instructions, it would have been better if I would have used hardwood sawdust or fine wood chips for the base, or if I would have soaked the straw for a few days first. But between spending time at the cottage and work travel, my time to work on this is limited and I decided to go for it anyway just using dry straw.
Since I didn’t pre-soak my straw, I gave it a good spray with the hose to get some moisture close to the soil. I crumbled up the sawdust spawn and spread that over the straw, and then covered that with the remaining straw so that it was a few inches deep. Then I set up a sprinkler and gave the whole area a good long soak.
I kept the sprinkler in place so that I can water the area again if we don’t get rain for a while. But otherwise, I just have to wait and see what happens. Stay tuned!
