Wondering if you're giving your urban planter boxes a little too much love with the watering can? Overwatering is a common issue that can be just as harmful as neglect. Here’s how to know if your plants are getting too much water.
First, check the soil. Before you water, push your finger about an inch into the soil. If it feels wet or clings to your finger, hold off on watering. The top layer can be deceiving; the moisture level below the surface is what truly matters.
Next, look at the leaves. Yellowing leaves, particularly on the lower part of the plant, are a classic early sign of too much water. If the leaves start to feel soft and mushy or appear swollen, it's a clear indicator. In severe cases, you might see blisters or lesions.
Don't forget to inspect the roots. If you suspect overwatering, gently remove the plant from its box. Healthy roots are firm and white. Overwatered roots will be brown, black, mushy, and may have a foul, rotten smell. This is root rot, a serious condition caused by waterlogged soil.
Finally, be vigilant for mold and pests. Consistently soggy soil creates the perfect environment for green algae or white, fuzzy mold to grow on the surface. It can also attract fungus gnats, which look like tiny flies hovering around the soil.
The best fix is always prevention. Ensure your planter boxes have adequate drainage holes. Use a well-draining potting mix, not heavy garden soil. Adjust your watering schedule with the seasons—plants often need less water in cooler, cloudier weather. When in doubt, it's safer to underwater.
