Why You Should Use Kitchen Sponges To Help Your Potted Flowers Thrive
By ROCHELLE HEATH-HARRIS
Over-watering is quite common in potted plants and can lead to root rot, but using a kitchen sponge can aerate the soil and provide better drainage for a healthier root system.
Place a few small sponges at the bottom of the planter before adding soil. Ensure you're not using old or pretreated sponges with detergents or antibacterial compounds.
The sponges will absorb moisture and retain water that would typically sit at the bottom of the planter once the plant has had enough to drink.
Wet sponges will help keep the soil moist, save you money for potting soil as they take up space in the container, and make the containers lighter to carry.
