Are your urban plants looking unhappy despite your regular watering? You might be giving them too much love. Overwatering is one of the most common mistakes in container gardening, and it can be fatal. Here’s how to diagnose it.
First, check the leaves. Are they turning yellow and feeling soft and limp? This is a classic sign, often mistaken for underwatering. If the leaves are yellow but the soil is wet, you've likely found the culprit. Wilting is another confusing signal; a plant wilts when it's too dry, but also when its roots are drowning and can't absorb oxygen.
Next, feel the soil. Don't just trust the surface. Push your finger about an inch or two down into the soil. If it feels consistently wet or soggy, your plant does not need more water. A musty smell emanating from the soil is another red flag, indicating a lack of oxygen and potential root rot.
Look for leaf drop. An overwatered plant may drop both old and new leaves. Also, be vigilant for mold or algae, which appear as a white or green fuzzy layer on the soil surface. This fungus thrives in excessively moist conditions.
Finally, inspect the roots if you can. Gently remove the plant from its planter. Healthy roots are firm and white. Roots suffering from rot will be dark brown or black, mushy, and may have a foul odor.
The solution is simple: let the soil dry out. Before you water again, always perform the finger test. Ensure your planter boxes have adequate drainage holes. Consider the season; plants often need less water in cooler, cloudier weather. By paying attention to these signs, you can adjust your routine and keep your urban garden thriving.
