What to do if the second flush of mushrooms does not appear? Causes and solutions
Normally, after the first flush of mushrooms is harvested, the second flush will begin to appear in about 10 days. In some cases, no mushrooms appear for a long time. The main reasons are, first, a high yield in the first flush and too long a growing period, causing a serious shortage of water content in the growing medium; second, temperature that is too low or too high, affecting the timing and yield of the next flush.
The solution is to soak the growing medium bags in clean water for 1-2 hours, adding to the water 1% white sugar, 0.3% potassium dihydrogen phosphate, 0.5%-1% magnesium sulfate, 0.1% urea, and 0.1% zinc sulfate, which is even better and can improve yield and quality. After they absorb enough water, cultivate them again at a suitable temperature, and mushrooms will soon appear.
