1. Mix compostable material together

Mushrooms can’t form enriching compost on their own; therefore, you’ll need to combine them with other elements to make homemade compost. Combine the mushrooms with items such as…

  • Leaves
  • Wood shavings
  • Newspaper
  • Straw
  • Hay
  • Cardboard
  • Kitchen scraps
  • Grass clippings
  • Manure

Avoid things like meats, greases, and processed meals when putting kitchen wastes into your mushroom compost. For your homemade compost recipe, stick to fruits and vegetables. If you’re going to utilize dung, be sure it’s not from pets like dogs or cats. Use dung from cows, horses, or llamas instead.

2. Saturate your compost pile

Once you’ve gathered all of your compostable stuff in a bin, water it with the yard hose until it feels like a wet sponge. Water the compost pile frequently but not excessively, or it will rot rather than decompose. Warm and wet, not soggy and saturated, is how the compost pile should feel.

If you’re new to composting, a thermometer can help you keep track of how far your compost pile has progressed. As it “cooks,” the middle of the pile should be approximately 130 to 150 degrees Fahrenheit.

3. Turn Your Compost Pile Weekly

Once your compost pile has achieved an interior temperature of 130 to 150 degrees Fahrenheit, you should toss it with a shovel or pitchfork once a week. This allows air to flow throughout the pile, assisting the composting process and preventing waste from becoming squashed, producing an odor, or rotting.

4. When Your Mushroom Compost is Ready

When your mushroom compost is no longer warm, dry, and crumbly, you know it’s ready to use. It will also have a basic brown tint, similar to the compost you would buy at a store. Make sure you apply a thin coating of fertilizer to your garden, around an inch deep. This will guarantee that your plants receive additional nutrients without wasting any.

Final Thoughts

If you notice new unattractive lawn mushrooms growing in your mulch, remember to watch the quantity of water you use and follow these guidelines. When the mulch needs to be replaced, removed, or raked, do so. Prepare to welcome a mushroom or two into your garden as a welcome addition.
