Reduce, Reuse, Recycle, Respect
Recycle your old sponges in your potted plants. Especially good for keeping outdoor soil pots moist, old cellulose sponges make the perfect bottom component of planted pots.
- Rinse the old sponge throughly to remove any soap residue.
- Cut sponge to fit into plant pot, place in pot, then cover with potting soil, and add plant(s) and top off with soil. Compress soil gently with hands.
- Water in!
The great thing about sponges is that they will absorb and hold excess water and slowly release it to the soil – so it essentially create a home made self-watering pot. The sponges also hold dirt in (for those pots with larger drainage holes). Plus, now you finally have something to do with your old sponges!
