Watching your urban garden thrive is rewarding, but plants confined to planter boxes can silently signal distress. Knowing when to give them more room is key to their health. Here are five clear signs your plants are root-bound and need repotting.
First, check for roots growing out of the drainage holes. This is one of the most obvious indicators that the root system has exhausted the available space below and is searching for new territory. Second, notice if water runs straight through the soil without being absorbed. This happens when roots have taken over so much space that little potting mix remains to retain moisture. Third, observe the plant's growth. Has it stopped producing new leaves or flowers despite adequate sunlight and fertilizer? Stunted growth often points to restricted roots. Fourth, gently lift the plant from its container. If you see a dense, circular mat of roots encircling the soil ball, the plant is pot-bound. Finally, wilting frequently, even when watered regularly, can signal that the roots are too crowded to take up water and nutrients effectively.
To address this, choose a new container that is only 1-2 inches larger in diameter. Gently loosen the root ball before placing it in fresh, high-quality potting soil. With more space, your plants will quickly return to vigorous growth, ensuring your urban green space remains lush and productive.
