Once your setup is ready, and you have your spores or spawn, you’re prepared to move on to the planting and inoculation stage. Remember, patience and attention to detail are key in mushroom cultivation.

Planting and Inoculation

Planting Black Trumpet mushrooms is a unique process due to their mycorrhizal nature, which means they form a symbiotic relationship with certain tree roots. Here’s how to proceed:

1. Preparing the Spores or Spawn: If you have obtained Black Trumpet spores or spawn, begin by preparing them according to the supplier's instructions. This often involves soaking or mixing them with a substrate.
2. Inoculating the Substrate: Spread the prepared spores or spawn evenly across the substrate. If using wooden beds or logs, drill holes and insert the spawn, then seal with wax. This mimics the natural process where spores infiltrate tree bark. You can check our detailed mushroom inoculation guide.
3. Creating the Right Environment: After inoculation, cover the substrate with a thin layer of soil or additional leaf litter to protect the spores. Maintain the humidity and temperature as discussed earlier.
4. Monitoring and Patience: Black Trumpet mushrooms may take several months to a year to start showing growth. Regularly check the substrate for any signs of mushroom formation. Ensure the environment remains consistent, and adjust as needed.
5. Natural Symbiosis: If possible, introduce the inoculated substrate near the roots of living hardwood trees like oaks or beeches. This encourages the natural mycorrhizal relationship and can enhance the growth and yield of your mushrooms.

Remember, growing Black Trumpets is more challenging than other mushroom varieties due to their complex life cycle and specific environmental needs. Patience and careful monitoring are essential during this phase.

Care and Maintenance

Once you have planted your Black Trumpet mushrooms, consistent care and maintenance are crucial for successful cultivation. Here are key practices to follow:

1. Moisture Management: Keep the substrate consistently moist but not waterlogged. Use a fine mist spray to gently water the area, ideally twice a day. Avoid over-watering, as this can lead to mold growth.
2. Monitoring Temperature and Humidity: Use a thermometer and hygrometer to keep a close eye on the growing environment. Maintain the temperature between 50°F and 70°F (10°C to 21°C) and humidity levels between 75% and 90%.
3. Checking for Growth: Regularly inspect the substrate for signs of mycelium growth (white, thread-like structures). This is an indication that your mushrooms are developing correctly.
4. Pest and Disease Control: Watch for any signs of pests or diseases. Common issues include mold and mushroom flies. Address any problems promptly, using organic or recommended treatments to avoid contaminating the mushrooms.
5. Adjusting Conditions as Needed: Depending on the growth progress and environmental changes, be prepared to adjust the moisture levels, temperature, or humidity. Adapting to the mushrooms' needs is key to successful cultivation.

Remember, growing Black Trumpet mushrooms can be a slow process. It's important to remain patient and attentive to the subtle needs of the mushrooms throughout their growth cycle.
