The Pros and Cons of Using Sponges in Potted Plants.

The "sponge" hack for potted plants, which involves cutting up sponges and placing them at the bottom of the planter before adding soil, has been touted as a way to help plants retain excess moisture and prevent root rot. However, gardening experts warn that waterlogged sponges can actually cause root rot and promote the growth of harmful microorganisms in the soil. Instead, they recommend using traditional drainage materials such as gravel or sand. The sponge hack may be useful in specific scenarios, but proper watering practices and well-draining soil mixes are the best ways to ensure healthy plant growth.
