Move your kit outdoors

Moving your mushroom kit outdoors can be an effective way to revitalise it and encourage further growth. Here are some detailed steps and considerations to help you successfully move your mushroom kit outdoors:

Select an appropriate location: Choose a shady spot in your outdoor space, as direct sunlight can inhibit mushroom growth. Additionally, consider the specific needs of the mushroom species you are cultivating. Some mushrooms prefer cooler environments, while others may require more warmth. For example, Pink Oyster mushrooms won't fruit outdoors unless temperatures are above 70 degrees Fahrenheit.

Create a favourable microclimate: Mushrooms thrive in humid environments. You can create a humid microclimate by placing the kit under vegetation, such as fern fronds or potted plants. This helps protect the kit from direct sunlight while maintaining humidity.

Maintain moisture: Keep the plastic on your kit to retain moisture and prevent the block from drying out. Spray the kit periodically, especially on dry and humid days, just as you would when it was indoors.

Monitor temperature shifts: Changes in temperature can stimulate fruiting. After heavy rainfall or a significant temperature shift, check your kit for signs of new growth. Mushrooms may start to appear after such weather events.

Bury the mushroom block: Consider burying the mushroom block in the soil. This helps protect it from the elements, and the fungi can wick moisture from the nearby soil. Adding a layer of mulch or soil on top provides additional protection from direct sunlight.

By following these steps and maintaining the right environmental conditions, you can increase the chances of successful outdoor mushroom cultivation and extend the life of your mushroom kit.

Bury the mushroom block

Burying the mushroom block outdoors is an effective way to reuse your mushroom kit. This method protects the block from the elements, allowing the fungi to wick moisture from the nearby soil. Before burying the block, ensure that you have removed it from the box and recycled the box.

When selecting a location to bury the block, opt for a shady or semi-shady area in your garden. This helps to maintain the necessary humidity levels and provides a buffer from direct sunlight. You can further enhance the humidity by placing the block under the cover of vegetation, such as fern fronds, which creates a humid microclimate for the fungi to thrive.

As you prepare the burial site, consider adding mulch or soil on top of the block. This additional layer offers extra protection from direct sunlight and helps maintain moisture. Generously water the patch to ensure it doesn't dry out, as proper hydration is crucial for mushroom growth.

If you're feeling adventurous, try burying different types of blocks next to each other to create a unique landscape feature. With some patience and care, you can expect vibrant mushroom bouquets to burst from the ground in a couple of weeks!

Make mushroom clay

Making mushroom clay sculptures is a fun way to reuse your mushroom kit. Here is a step-by-step guide to making mushroom clay:

Preparing the Clay

Firstly, prepare the clay by kneading it until it is soft and malleable. You can use air-dry clay or polymer clay for this project. If you want to make your own clay, you can find recipes online. However, if you don't feel like making clay, you can purchase air-dry clay or polymer clay from craft stores or online.

Forming the Mushroom Stems

Take a small piece of clay and roll it into a ball. Then, roll the ball into a long, thin cylinder, thicker at one end, to form the stem of the mushroom. The thicker end will be the bottom of the stem, which you can flatten to create a stable base. You can curve the stem if you prefer a more natural look. Use a toothpick to create a hole in the base of the stem, which will help secure the mushroom in the soil or moss when placing it in a planter.

Creating the Mushroom Caps

Roll out another piece of clay into a ball, this time slightly larger than the stem. Flatten the ball slightly and press it in the center with your thumb to create a domed shape. You can use your fingers to shape and flatten the edges, creating a tapered look for the mushroom cap. Make sure the cap is at least 1/4 inch thick.

Attaching the Stems and Caps

To attach the stem and cap together, dab a small amount of water on the top of the stem and the center of the cap's bottom. Center the cap on the stem and gently push down to connect the two pieces. You can also use glue to attach the pieces, especially if you want to paint the mushroom before assembling it.

Drying and Baking the Mushrooms

Allow the mushrooms to air dry for 2-3 days at room temperature. Alternatively, you can bake them in the oven to speed up the drying process. Place the mushrooms on a parchment-lined baking tray and bake at 200°F for around 1 hour.

Painting and Decorating (Optional)

Once the mushrooms are dry, you can paint them with acrylic paint or tempera paint, depending on your preference and whether children are involved in the project. You can also add decorations, such as jump rings or twine, by pressing them into the clay while it is still soft.

Displaying Your Mushroom Clay

Your mushroom clay sculptures are now ready to be displayed! You can place them in planters with soil or moss, glue them into foil, or simply set them on a shelf as cute ornaments.

Feel free to experiment with different colors of clay, create various mushroom cap shapes, and explore different ways to display your mushroom clay creations. Enjoy your whimsical and magical mushroom clay journey!

Assess the kit's condition

To assess the condition of your mushroom kit, start by examining the substrate for any signs of contamination or depletion. Look out for mould or bad smells, as these are indicators that the substrate may not be suitable for reuse. If the substrate appears healthy and free of any contaminants, it is likely still viable for another crop of mushrooms.

It is important to carefully inspect the kit for any remaining mushroom parts or debris. This includes spent substrate and any other organic matter that may be left over from the previous crop. Removing all remnants of the previous crop is essential to prepare the kit for the next one.

Once the kit has been thoroughly inspected and all visible contaminants have been removed, it is time to clean and sterilize it. This step is crucial to prevent the growth of unwanted bacteria or fungi that could hinder the development of your new mushroom crop. Use hot, soapy water to wash the container, and then rinse it thoroughly with clean water to eliminate any soap residue.

After cleaning, sterilize the kit using a mild bleach solution (one part bleach to ten parts water) or a natural disinfectant like vinegar. Allow the kit to air dry completely before adding fresh substrate. Proper sanitation is key to combating pests and diseases that could affect your mushroom crop.

Additionally, pasteurizing the substrate by heating it can be an effective way to reduce the risk of contamination. This step can be done before or after introducing the new mushroom spores or spawn into the substrate.

Clean and sterilise the kit

Before attempting to reuse your mushroom kit, it is important to assess its condition to ensure a successful second harvest. Start by examining the substrate for any signs of contamination, such as unusual colours or odours, which could indicate bacterial or fungal issues. The presence of mycelium, the white thread-like structures, is a positive sign that your kit is still viable. If the mycelium appears healthy and spread throughout the substrate, your kit may be ready for another cycle.

The next crucial step is cleaning and sterilisation. This process is vital to remove any contaminants that could hinder the growth of new mushroom crops. Begin by removing all spent substrate and any remaining mushroom parts from the kit. Wash the container with hot, soapy water and rinse thoroughly with clean water to remove any soap residue.

Sterilise the kit using a solution of bleach and water (1 part bleach to 10 parts water) or use a natural disinfectant like vinegar for a more eco-friendly option. Allow the kit to air dry completely before adding fresh substrate. Sanitation is a foundational step in combating pests and diseases in mushroom cultivation.

If you are feeling crafty, you can even create your own mushroom clay with the substrate block! All you need is equal parts substrate, glue, and cornstarch. Combine these ingredients in a large mixing bowl and knead the mixture until it becomes stiff. You can then form the clay into whatever shape you like. Place your creation in an airtight container to let it dry for 1-2 days, or speed up the process by putting it in the oven at a low temperature for one hour.
