Wood Ear
Auricularia Angiospermarum
Wood Ear mushrooms, known scientifically as Auricularia Angiospermarum, are prized for their culinary uses and unique texture. Originating from Asia, they thrive in moist, shaded environments and are relatively easy to cultivate, making them a favorite among mushroom enthusiasts.
Everything it needs
9 essentials at a glance
Watering
Water the Wood Ear mushroom regularly to keep the substrate consistently moist but not soggy.
During the growing season, water every 2-3 days, ensuring the substrate is damp. In cooler months, reduce watering frequency to once a week. Signs of over-watering include a slimy texture on the substrate and a foul odor, while under-watering may cause the mushrooms to dry out and shrivel.
Light
Wood Ear mushrooms thrive in low to moderate light conditions.
They prefer indirect light and should be placed in a shaded area or under a grow light for about 12 hours a day. Avoid direct sunlight, as it can dry out the substrate and inhibit growth.
Soil
Ideal substrate for Wood Ear mushrooms includes hardwood sawdust or a mix of straw and wood chips, with a pH range of 5.5 to 6.5.
Ensure good drainage and aeration to prevent waterlogging. A commercial mushroom growing mix can also be used for optimal results.
Humidity
Wood Ear mushrooms prefer high humidity levels of around 85-95%.
To increase humidity, mist the growing area regularly or use a humidity dome. Signs of humidity stress include dry caps and stunted growth, while excessive humidity can lead to mold growth.
Temperature
The ideal temperature range for Wood Ear mushrooms is 60-75°F (15-24°C).
They can tolerate temperatures as low as 50°F (10°C) and as high as 80°F (27°C) but may stop fruiting outside the ideal range. They grow best in hardiness zones 7-10.
Fertilizing
Use a balanced organic fertilizer with an NPK ratio of 5-10-10 during the growing season, applying every 4-6 weeks.
Signs of nutrient deficiency include slow growth and pale caps. Adjust fertilization based on growth performance.
Pruning
Pruning is not typically necessary for Wood Ear mushrooms.
However, if any fruiting bodies appear unhealthy or diseased, use sterilized scissors to remove them. This helps to promote healthy growth and prevents the spread of disease.
Repotting
Repotting is not applicable for Wood Ear mushrooms as they grow in a substrate.
However, if the substrate becomes exhausted (after 2-3 fruiting cycles), replace it with fresh substrate. Signs of exhaustion include reduced fruiting and smaller caps.
Propagation
Wood Ear mushrooms can be propagated using spawn or by inoculating a substrate with mycelium.
To do this, prepare the substrate, sterilize it, and inoculate it with Wood Ear spawn. Cover and maintain humidity until the mycelium colonizes the substrate, then expose it to light for fruiting. Best timing for propagation is in spring or fall.
When it's unhappy
Mold growth
Why it happens
Excessive humidity and poor air circulation.
How to fix it
Reduce humidity levels and improve ventilation. Remove affected areas and ensure proper sanitation.
Dry caps
Why it happens
Low humidity levels.
How to fix it
Increase humidity by misting or using a humidity dome to maintain moisture.
Slow growth
Why it happens
Nutrient deficiency or unsuitable temperature.
How to fix it
Fertilize with a balanced organic fertilizer and ensure the temperature is within the ideal range.
Discoloration
Why it happens
Poor light conditions or nutrient imbalance.
How to fix it
Ensure adequate indirect light and adjust fertilization as needed.
Shriveling
Why it happens
Under-watering.
How to fix it
Increase watering frequency to keep the substrate consistently moist.
Care through the year
Spring
In spring, ensure the substrate is prepared and inoculated for optimal growth. Maintain humidity and monitor temperatures as they rise.
Summer
During summer, keep the growing area cool and shaded. Increase misting frequency to combat heat and maintain humidity levels.
Fall
In fall, continue to monitor humidity and temperature as they drop. This is a good time for propagation and preparing for the next growing cycle.
Winter
In winter, reduce watering frequency and ensure the growing area remains warm enough to prevent dormancy. Maintain humidity to promote healthy growth.
Toxicity & Safety
Wood Ear mushrooms are non-toxic and safe for pets and children. They are edible and commonly used in cooking. However, ensure they are properly identified before consumption, as some look-alikes can be toxic.
