Are your urban planter box plants trying to tell you something? When greenery outgrows its container, it sends clear distress signals. The most obvious sign is roots escaping through drainage holes or circling the soil surface – a condition called being root-bound. You might notice slowed growth despite proper care, with plants producing smaller leaves and fewer flowers. Soil that dries out unusually fast indicates more roots than earth. Another clue is yellowing lower leaves as the plant struggles to absorb nutrients. Gently slide your plant from its container to inspect; if you see a dense root web with little soil visible, it's time for an upgrade. For quick relief, move plants to containers 2-4 inches wider, or divide overcrowded perennials. Regular root checks every growing season will keep your urban garden thriving in its limited space.
How can I tell if the plants in my urban planter boxes need more space?
