Mushrooms can survive in the soil for several months. However, to maintain their effectiveness, it’s recommended to replace them regularly. Because mushrooms lose moisture over time, it’s recommended to check their condition and replace them every 3 to 6 months for optimal results.
Can I use mushroom material that has already decomposed?
Avoid highly decomposed mushroom material, as it retains moisture poorly and spoils too quickly. Overly decomposed mushrooms lose their structure and effectiveness, reducing their ability to aerate the soil and retain water. Use mushrooms that are in good condition for optimal results in your garden.
Tips and practical tips for using biodegradable sponges.
Biodegradable sponges are ideal because they decompose naturally without harming the environment. 
By choosing sponges made from natural materials, you contribute to reducing pollution and protecting ecosystems. These sponges, often made from cellulose or other natural fibers, decompose completely, leaving no toxic residue.
Ensure good soil aeration: A soil-sponge mixture improves soil aeration, which is essential for proper root growth. Sponges create air spaces in the soil, promoting oxygen circulation and preventing compaction.
To further improve aeration, you can add sand to the mix. 
Sand contributes to a looser soil structure, allowing roots to spread more easily and absorb nutrients and water more effectively. Here’s how:
Preparation of the mixture:
Mix garden soil with pieces of sponge. Add sand in a ratio of 1 part sand to 3 parts soil and sponge mix.
Mix thoroughly: Mix thoroughly to ensure even distribution of sand, sponge pieces, and soil. Ensure the sand is thoroughly mixed to maximize its positive effect on soil aeration.
With these practical tips, you can create optimal growing conditions for your plants while caring for the environment and sustainability.
3 mistakes to avoid when using sponges:
Using non-biodegradable synthetic sponges: Synthetic sponges are often made of non-biodegradable materials, such as plastic, that can pollute the environment as they decompose. Using biodegradable sponges is important to minimize environmental impact, as they decompose naturally and leave no harmful residue.
Not disinfecting sponges before use: Kitchen sponges, especially used ones, can harbor bacteria and other microorganisms. It’s important to thoroughly wash and disinfect sponges before using them in the garden. This can be done by soaking them in vinegar or baking soda for 24 hours, or using a bleach solution for a more thorough disinfection. A clean sponge ensures you don’t introduce pathogens into the soil, thus protecting the health of your plants.
Using already rotten or over-rotted sponges
Worn: Heavily worn or weathered sponges no longer retain moisture—one of their primary functions in the garden. Furthermore, severely damaged sponges can quickly rot in the soil, reducing their ability to aerate the soil and protect plant roots. Therefore, it’s best to use sponges in good condition to ensure their effectiveness in the garden.
Two golden rules for successful gardening:
Always use clean and disinfected sponges: Before using used sponges in the garden, it’s important to thoroughly clean and disinfect them. This removes bacteria, mold, and other contaminants that could harm your plants. To do this, wash the sponges in warm water and disinfect them by soaking them in vinegar or baking soda for 24 hours. You can also use a bleach solution, but choose more environmentally friendly disinfectants whenever possible.
