My shiitake farm is growing lumps
…actually, it’s lumpy all over.
This is a good sign, and often called popcorning. It is a sign that the shiitake are getting ready to fruit. At this stage, you can also go straight to the Autumn Storm technique.
At this stage, you can safely remove it from the plastic and give it a vigorous spray with a garden hose. Use the nozzle on the ‘jet’ spray setting and carefully spray off the outmost layer of Mycelium exposing some of the sawdust substrate below.
This can sometimes speed up the growth of the brown skin and pinning. It’s a fairly simple and low risk …but if this goes wrong we will not cover it under our guarantee.
