Beds of six or more layers are possible in the wet season. Four or sixlayer beds are constructed, depending on the season. The leaf bed also requires the elevated plastic sheet on a bamboo frame immediately after planting. During the dry season, the bed may be watered gently but generously on the sixth or seventh day after planting, and this should be repeated once a day until the mushroom pin-heads have developed. During the rainy season, the bed may not need further watering, or at least not as much as during the dry months.
Water is applied more along the sides of the bed in the rainy season.
When the mushrooms are at the pin-head stage, the bed should not be watered. Water should be applied only when the mushrooms reach the size of corn seeds and the bed has become somewhat dry. Harvesting Under normal conditions, the first harvest of mushrooms is taken 10 to 14 days after planting. The harvest usually lasts for three consecutive days. This is the so-called first flush.
