Sponges can last several months in the soil. However, it is recommended that they be replaced regularly to maintain their effectiveness. As the 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 a better result.
Can I use already degraded sponges?
It is better to avoid excessively degraded sponges because they will not retain moisture well and could decompose too quickly. Too-sewn sponges lose their structure and efficiency, reducing their ability to help with soil ventilation and water retention. Use good-notch sponges to ensure optimal performance in your gardening.
Practical tips and advice
Use biodegradable sponges
Biodegradable sponges are ideal because they decompose naturally without harming the environment. By opting for sponges made from natural materials, you help to reduce pollution and preserve ecosystems. These sponges, often made of cellulose or other natural fibres, decompose without leaving toxic residues.
Ensuring good ventilation of the soil
The earth-sponge mixture allows better ventilation of the soil, which is crucial for the proper development of the roots. Sponges create air spaces in the ground, facilitating the flow of oxygen and preventing compaction from the soil.
To further improve ventilation, you can add sand to the mixture. The sand helps to maintain the structure of the loose soil, allowing the roots to expand more easily and absorb nutrients and water better. Here's how to do it:
Preparation of the mixture:
