1. An unsuitable spawn temperature type or sowing date can prevent fruiting. For example, a medium-to-low-temperature oyster strain sown in late spring may finish colonizing during weather too hot for fruiting.
Remedy: cover the substrate with soil in a shaded place through summer, then remove the soil and manage fruiting when autumn temperatures fall.
2. Excessive nitrogen-rich bran, rice bran or urea creates a relative carbon shortage, leading to excessive vegetative growth and a mycelial mat that delays fruiting and reduces yield.
Remedy: break the mycelial mat or skin with a small wire rake, improve ventilation, then apply the article's suggested 0.5% glucose or 1 ppm triacontanol to adjust the carbon–nitrogen balance. Moderate temperature differences, ventilation and light may promote pinning.
3. A few early mushrooms may be mistaken for normal fruiting, leading to bags being opened too soon. Warm, dry conditions then form a hard surface skin that prevents mycelium from forming primordia.
Remedy: replenish water according to moisture loss, then scratch the mycelial surface as described above. Moderate ventilation, light and temperature differences can encourage primordia formation.
