As the growing season ends, cleaning your urban planter boxes is crucial for next year's success. Start by removing all spent plants and roots. Shake off excess soil from the roots back into the box. Next, take out the old potting mix and place it in your compost bin, as it's likely depleted of nutrients. Now, scrub the empty planter box with a solution of one part vinegar to nine parts water to disinfect it and remove mineral deposits. Rinse thoroughly and let it dry. For the final step, refill the box with a high-quality, fresh potting mix. Consider adding a slow-release fertilizer to give new plants a strong start. This simple cleanup prevents disease, refreshes the soil environment, and sets the stage for another bountiful season on your balcony or patio.
