Spent mushroom blocks, also known as spent mushroom substrate (SMS), can be a valuable addition to your garden as a soil amendment or mulch. Utilizing this material involves a few simple steps to ensure it benefits your plants effectively.
Guide to Using Spent Mushroom Substrate
Based on gardening practices, incorporating spent mushroom substrate into your garden primarily involves applying it directly to the soil surface as a mulch or incorporating it into the soil structure.
Step-by-Step Application
According to guidance on using spent mushroom substrate, here are the key steps to follow:
- Put the spent substrate straight on the soil.
- Apply the material directly onto the surface of your garden beds or around plants. This allows it to work its way into the soil over time and act as a protective layer.
- Make sure the spent substrate is laid down at least 5 cm thick.
- A sufficient layer is necessary for the substrate to effectively suppress weeds, retain moisture, and contribute organic matter to the soil. Aim for a minimum thickness of 5 centimeters.
- Make sure the spent substrate is in a shady place or add a thin layer of leaves, bark, wood chips or landscape fabric on top of the bed.
- Keeping the substrate moist is crucial. Applying it in naturally shady areas or covering it with materials like leaves, bark, wood chips, or landscape fabric helps prevent it from drying out quickly, maintaining its beneficial properties.
- Water regularly.
- Consistent moisture is essential for the spent substrate to break down gradually and for any potential residual fungi to remain dormant rather than drying out and becoming airborne. Regular watering supports its function as a mulch and soil conditioner.
Summary of Application
| Step | Action | Purpose |
|---|---|---|
| 1. Direct Application | Place spent substrate directly onto garden soil. | Acts as mulch and soil amendment. |
| 2. Apply Thick Layer | Lay down at least 5 cm (approx. 2 inches) of substrate. | Effective weed suppression and moisture retention. |
| 3. Location/Cover | Apply in shady spots OR cover with leaves, bark, wood chips, etc. | Prevents drying out, maintains beneficial properties. |
| 4. Water Consistently | Water the applied substrate regularly. | Aids decomposition and maintains desirable moisture levels. |
By following these steps, you can effectively integrate spent mushroom blocks into your garden, improving soil health and suppressing weeds.
