When it’s time to replace your kitchen sponge, your first instinct might be to toss it in the trash. But did you know that old sponges can be incredibly useful in your garden? Instead of discarding them, you can give these humble household items a new purpose, reducing waste and enhancing your gardening efforts. Here’s how old sponges can benefit your plants and garden.

Old sponges are excellent at absorbing and retaining water, making them perfect for keeping your soil moist. Place a few clean, used sponges at the bottom of your potted plants before adding soil. They will:
- Absorb excess water, preventing overwatering.
- Slowly release moisture back into the soil, keeping your plants hydrated for longer.
This technique is especially useful for plants that need consistent moisture, such as herbs and ferns.

Sponges can also enhance drainage in pots and planters. By lining the bottom of the container with sponges, you:
- Allow excess water to drain away, preventing root rot.
- Maintain a lightweight pot, unlike heavy gravel or stones.
