  • The mycelium (the vegetative part of the fungus) needs to colonize the substrate before the mushrooms start to fruit.
  • During the incubation period, the mycelium will establish itself and spread throughout the growing medium.
  • Once the substrate is fully colonized, small pin-like structures will begin to form, which are the precursors to the actual mushroom caps.
  • From pinning to harvest, it usually takes about 7 to 14 days for the shiitake mushrooms to reach maturity.
  • Harvesting should be done when the caps have fully opened but are still relatively young and firm.

Oyster Mushrooms

Oyster mushrooms are incredibly versatile and are prized for their delicate flavor and velvety texture. Here’s what you should know about growing oyster mushrooms:

  • Oyster mushrooms have a relatively quick growth cycle, with a harvestable crop typically ready within 3 to 4 weeks from the time of inoculation.
  • The mycelium of oyster mushrooms is fast-growing and aggressive, allowing for rapid colonization of the substrate.
  • Once the substrate is fully colonized, the mushrooms will start to develop clusters of small, white pinheads.
  • These pinheads will gradually enlarge and unfold, eventually forming the characteristic umbrella-shaped caps of oyster mushrooms.
  • Depending on the specific strain and growing conditions, oyster mushrooms can be harvested when the caps are fully grown but still firm and before they begin to release spores.

White Button Mushrooms

White button mushrooms are the most widely consumed mushroom variety worldwide, known for their mild flavor and versatile culinary uses. Here’s what you can expect when growing white button mushrooms:

  • The growth cycle for white button mushrooms ranges from 2 to 3 months, varying depending on the specific cultivation method and environmental conditions.
  • It all starts with the mycelium colonizing the substrate, which could be a mixture of compost, manure, and other organic materials.
  • Once fully colonized, the mycelium starts to form small, pin-like structures called primordia.
  • These primordia will continue to grow and mature, eventually forming the classic dome-shaped caps and short stems that white button mushrooms are known for.
  • Harvesting is typically done when the caps have reached their desired size and just before the veil underneath the cap breaks, exposing the gills.

So there you have it – the typical timelines for growing shiitake mushrooms, oyster mushrooms, and white button mushrooms. Whether you’re a beginner or an experienced grower, understanding these timelines can help you plan and anticipate the exciting journey of mushroom cultivation.
