Wondering if your urban planter box has enough drainage? Proper drainage is crucial to prevent waterlogged soil and root rot. Here's how to check. First, look at the bottom. Are there holes? A good rule is one half-inch hole for every square foot of soil surface. For a long planter, several holes spaced along the base are best. Next, perform a simple water test. Pour a moderate amount of water into the empty planter and observe how quickly it drains out. Slow dripping or no flow means inadequate drainage. Also, check if the holes are blocked by a flat surface or a saucer that isn't elevated. Finally, observe your plants after watering. If the soil stays soggy for days or if plants show yellowing leaves and stunted growth, poor drainage is likely the culprit. Ensure your planter has clear, unobstructed holes and use a well-draining potting mix for healthy urban greenery.
