Don’t Throw Away Old Sponges: “They’re Worth Their Weight in Gold” | I Still Use Them Like This in the Garden

Protect Roots
Sponges provide additional protection to roots, helping them grow stronger and healthier. By creating a stable, well-aerated environment, sponges reduce stress on roots, facilitating their development. In addition, sponges prevent roots from rotting by preventing excessive water accumulation, while providing a protective barrier against temperature fluctuations and physical shocks.

Frequently Asked Questions
Are all sponges suitable?
No, it is advisable to use biodegradable sponges and not synthetic ones so as not to pollute the environment. Biodegradable sponges, made from natural materials such as cellulose, decompose without leaving toxic residues, unlike synthetic sponges which can release microplastics and other pollutants.

How long do sponges last in soil?
Sponges can last several months in the soil. However, it is recommended to replace them 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 best results.

Can I use sponges that are already degraded?
It is best to avoid sponges that are too degraded because they will not retain moisture well and may 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 garden.

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.
