Wondering if your urban garden is thriving or just surviving? A key factor often overlooked is root space. Plants confined to small planter boxes can become "root-bound," stunting their growth and health. Here’s how to perform a simple check.
First, look for visual clues above the soil. Is growth slowed or halted despite proper care? Are leaves yellowing, wilting, or browning at the edges? Do you notice roots visibly circling the soil surface or poking out of the drainage holes? These are strong indicators that your plant is pot-bound.
For a definitive diagnosis, you need to look at the root ball itself. Gently remove the plant from its container. If you see a dense, tangled web of roots completely encircling the soil, with little dirt visible, the plant has outgrown its home. Healthy roots should be firm and spread loosely through the soil, not form a tight, matted mass.
When you confirm your plant is root-bound, it's time for action. Gently loosen the outer roots with your fingers to encourage them to grow outward. Then, repot the plant into a container that is one to two inches larger in diameter. This provides the necessary space for continued healthy growth, allowing your urban plants to flourish once more.
