Oyster mushrooms are a delicious and nutritious addition to any meal, and growing them can be a rewarding experience. But how do you know when your oyster mushrooms are ready to harvest? And what is the best way to harvest and store them? In this guide we answer all your questions about harvesting mature oyster mushrooms.
How to Harvest Oyster Mushrooms?
Identification of Maturity
The first thing you need to know is how to tell if your oyster mushrooms are ready to harvest. Here are some signs that your oyster mushrooms are mature:
- Hat brim: The brims of the hats begin to curl or flatten.
- Color: The hats have a uniform color without spots.
Harvesting techniques
There are several methods of harvesting oyster mushrooms, but the most common are:
- Cutting: Use a clean, sharp knife or scissors to cut the mushrooms at the base of the stem, as close to the growing medium as possible.
- Turning: You can also gently turn the mushrooms to remove them from the substrate. This works especially well with bunches, where the base usually breaks off in its entirety.
Post-Harvest Care
After harvesting, it is important to properly care for the growing medium to prevent further contamination and encourage future harvests:
- Inspection: Check the growing medium for and remove any remaining stems or debris.
- Humidity: Keep the medium moist by misting it lightly with water, especially if the mushrooms begin to dry out.
- Storage: Store freshly harvested oyster mushrooms in a paper bag in the refrigerator for up to one week. For longer storage, the mushrooms can be dried and later rehydrated by soaking them in water.
Which Oyster Mushroom is the Tastiest?
There are several types of oyster mushrooms, each with their own unique taste and texture. Here are some popular varieties:
- Gray Oyster Mushroom: Has a mild, nutty flavor and a soft texture. Ideal for stir-fries and soups.
- Blue Oyster Mushroom: Starts out deep blue and turns dark gray with age. Has a meatier texture and a rich umami flavor. Perfect for pasta and stews.
- Pink Oyster Mushroom: Has a delicate, slightly sweet taste and a velvety texture. Great for salads and light dishes.
How to Harvest Mushrooms?
In addition to oyster mushrooms, there are many other types of mushrooms that you can grow and harvest. Here are some general tips for harvesting mushrooms:
- Timing: Harvest mushrooms when they are fully mature but before they start to age. This is usually when the caps have fully opened and the edges begin to curl.
- Clean Tools: Always use clean tools to prevent contamination.
- Caution: Take care when harvesting not to damage the mycelium (the underground network of fungal threads) so that the medium can produce multiple harvests.
How do you store oyster mushrooms?
Properly storing oyster mushrooms is crucial to maintain their freshness and flavor. Here are some tips:
- Refrigeration: Store freshly harvested oyster mushrooms in a paper bag in the refrigerator. They stay fresh for up to a week.
- Drying: For longer storage, oyster mushrooms can be dried. Cut them into thin slices and dry them in a dehydrator or in an oven at a low temperature. Store the dried mushrooms in an airtight container in a cool, dark place.
- Freezing: You can also freeze oyster mushrooms. First blanch them briefly in boiling water, let them cool and then freeze them in airtight bags or containers.
Multiple Harvests
Oyster mushroom growing medium can often produce multiple harvests. Here are some tips to maximize this:
- Humidity: Keep the medium moist and in the right conditions (10-20 degrees Celsius, out of direct sunlight) to encourage further growth.
- Rest period: After each harvest, give the medium a rest period of about a week before expecting new mushrooms.
- New Batch: If no new mushrooms appear after a few weeks, you can start a new batch with the remaining substrate mixed with fresh coffee grounds and new spawn.
Specific Tips for Blue Oyster Mushrooms
Blue oyster mushrooms are a popular variety because of their unique color and flavor. Here are some specific tips for harvesting and caring for blue oyster mushrooms:
- Harvest time: Harvest blue oyster mushrooms just before they are fully mature to preserve more energy and extend shelf life.
- Harvest cycles: Expect approximately 2 to 4 harvests from the same substrate, with each harvest cycle lasting approximately 7-14 days.
- Humidity: After each harvest, temporarily increase humidity to a maximum of 95% to prepare for the next fruiting cycle.
Common Problems and Solutions
You may encounter some problems when growing and harvesting oyster mushrooms. Here are some common problems and their solutions:
- Dehydration: If mushrooms begin to dry out, mist them with water to maintain humidity.
- Contamination: Immediately remove visible mold or unwanted fungi to prevent spread.
- No Growth: Ensure growing conditions are optimal and be patient, some batches may take longer to produce mushrooms.
By following these steps, you can successfully harvest mature oyster mushrooms and enjoy your homegrown mushrooms while keeping the growing medium healthy for future harvests.
