Sponges can last several months in the soil. However, it is recommended to replace them regularly to maintain their effectiveness. As sponges decompose, their ability to retain moisture decreases, so it is advisable to monitor their condition and replace them every 3 to 6 months for best results.
Can I use sponges that have already degraded?
It is best to avoid sponges that are too degraded because they will not retain moisture well and could decompose too quickly. Sponges that are too worn out lose their structure and effectiveness, which reduces their ability to help aerate the soil and retain water. Use sponges that are in good condition to ensure optimal performance in your gardening.
Tips and practical advice
Using biodegradable sponges
Biodegradable sponges are ideal because they decompose naturally without harming the environment. By opting for sponges made from natural materials, you help reduce pollution and preserve ecosystems. These sponges, often made of cellulose or other natural fibers, decompose without leaving toxic residues.
Ensure good soil aeration
The soil-sponge mixture allows for better soil aeration, which is crucial for good root development. Sponges create air spaces in the soil, facilitating the circulation of oxygen and preventing soil compaction.
To further improve aeration, you can add sand to the mixture. Sand helps maintain the loose structure of the soil, allowing roots to spread more easily and better absorb nutrients and water. Here’s how to do it:
Mix Preparation:

Combine garden soil with cut-up sponge pieces.
Add sand in a ratio of 1 part sand to 3 parts sponge-soil mixture.
Mix well:
Mix well to ensure even distribution of sand, sponge pieces, and soil.
Make sure the sand is well incorporated to maximize its beneficial effects on soil aeration.
By following these practical tips, you are creating an optimal environment for your plants to grow, while taking an eco-friendly and sustainable approach.
Top 3 Mistakes to Avoid When Using Sponges
Using Synthetic Sponges That Aren’t Biodegradable: Synthetic sponges are often made from non-biodegradable materials, such as plastic, which can pollute the environment when they decompose. Using biodegradable sponges is essential to minimize environmental impact, as they decompose naturally and do not leave harmful residues.
Not disinfecting sponges before using them: Kitchen sponges, especially those that have been used, can harbor bacteria and other microbes. It is crucial 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 by using a bleach solution for a more thorough disinfection. A clean sponge ensures that you are not introducing pathogens into your soil, thus protecting the health of your plants.
Using sponges that are already degraded or too worn: Sponges that are too worn or degraded are no longer effective at retaining moisture, one of the main reasons for using them in gardening. Additionally, sponges that are very degraded can quickly disintegrate in the soil, reducing their ability to aerate the soil and protect plant roots. Therefore, it is best to use sponges that are still in good condition to ensure their effectiveness in the garden.
The 2 Golden Rules for Successful Gardening
Always use clean and disinfected sponges: Before integrating your used sponges into the garden, it is essential to ensure that they are perfectly clean and disinfected. This will eliminate any traces of bacteria, mold or other contaminants that could harm your plants. To do this, wash the sponges in hot water and disinfect them by soaking them in vinegar or baking soda for 24 hours. You can also use a bleach solution, but prefer disinfectants that are gentler on the environment if possible.
Make sure the soil-sponge mixture is homogeneous: To fully benefit from the advantages of sponges in gardening, it is crucial to mix the sponge pieces well with the soil. A homogeneous mixture ensures that the sponges are evenly distributed, which allows for better moisture retention and optimal aeration of the soil. It also facilitates root growth by providing a stable and well-structured environment. For best results, mix the sponge pieces thoroughly with the soil in a bag or container before using it in your pots or garden beds.
