Wondering if your urban planter boxes have enough drainage? Proper drainage is crucial for healthy plants. Here's how to know for sure.
First, inspect the bottom. There should be multiple holes, not just one. A good rule is at least one hole for every square foot of soil surface area. For larger boxes, several holes spaced evenly are best.
Next, perform a simple water test. Pour a generous amount of water into the dry soil and watch the bottom. Water should flow out freely within a minute or two. If it pools on the surface or drains extremely slowly, you likely have insufficient drainage.
Watch for signs of poor drainage in your plants. Yellowing leaves, stunted growth, and a general look of wilting despite wet soil are key indicators. A musty smell from the soil is another red flag.
Finally, check the material. Ensure holes aren't blocked by a tightly attached saucer or a non-porous liner. Sometimes, debris or compacted soil can clog holes from the inside, so occasional cleaning is helpful.
By ensuring adequate drainage, you prevent root rot and create an ideal environment for your urban garden to flourish.
