Sponges can last for 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 as they will not retain moisture well and may decompose too quickly. Sponges that are too worn out lose their structure and effectiveness, reducing 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 choosing 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 proper 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:
