Cleaning and disinfecting your urban planter boxes between planting seasons is a crucial step for maintaining plant health and ensuring a successful harvest. Begin by completely removing all old plant debris and soil. Scrub the empty boxes thoroughly with a solution of mild dish soap and warm water using a stiff brush to remove dirt and mineral deposits. For disinfection, prepare a solution of one part white vinegar to nine parts water or a diluted bleach solution (1 part bleach to 9 parts water). Apply the disinfectant to all interior surfaces, let it sit for 10-15 minutes, then rinse the planter boxes completely with clean water. Allow them to air dry fully in the sun before adding fresh potting mix and new plants. This process eliminates harmful pathogens, pests, and fungal spores that could compromise your next season's growth.
