The gardener revealed how the used sponges are worth pure gold for plants because of their water retention capacity. She explained that people are “wasting a powerful ally for plants” by throwing away the old, worn-out sponges in their homes. The YouTube creator noted that sponges are made of plastic and may not be the best for the environment because of their long decomposition process. But we can put that characteristic to good use and enrich our gardens by utilizing the sponge in plant pots. As the weather warms up, gardeners and plant enthusiasts will struggle to protect their gardens from dehydration and overwatering at the same time.
Finding that right balance is a task, but with this sponge hack, gardeners can get used to bright flowers and lush greenery without fretting over the right amount of watering. Using a simple technique, sponges can be added to the potting soil or even the ground and help the plants retain moisture even during summer months. The longer and hotter days would no longer be a cause for concern with sponges layered beneath the plant that absorb and retain water for longer durations than the soil. This gardening hack is especially useful when done before July rolls in to prepare the garden for the heat waves and limitless sunlight. Sponges can also be used to keep plants hydrated when traveling.
Eventually, the sponge will mix with the soil and absorb the water in the soil. When the soil gets too dry or the plant is dehydrated, the sponge layer will act as a self-watering agent and help keep the plant green and fresh. The gardening expert shared that all her plants are potted with sponger layers in the soil. “I have been doing this for years. I just put a piece of sponge over the base of the pot. I am an addicted gardener and this has never caused any problems,” wrote @cherylmonopoli2896. Others were worried about the plastic nature of the sponges that could degrade soil quality, and also mentioned the risk of mold growth. “Since the sponges hold water and it is dark in the pots, this could be a prime setup for mold to grow,” stated @gardenspluswithwilsey1237.
