As the growing season ends, giving your urban planter boxes a thorough clean is crucial for next year's success. This process removes disease pathogens, pests, and residual salts that can harm new plants. Start by completely removing all old plant debris and soil; do not compost diseased material. Next, scrub the empty planter's interior and exterior with a stiff brush using a solution of one part white vinegar to four parts water—an effective, eco-friendly disinfectant. For persistent mildew or suspected disease, a diluted bleach solution (one part bleach to nine parts water) can be used; rinse thoroughly afterward. Allow the planter to dry completely in the sun before storing it in a cool, dry place over winter. This simple end-of-season ritual ensures your containers are a healthy foundation for another vibrant growing season.
