Knowing when to water your urban planter boxes can be tricky. Overwatering is just as harmful as underwatering. The most reliable method is the finger test. Simply insert your finger about two inches into the soil. If it feels dry at that depth, it's time to water. If it feels moist, wait another day.
Observe your plants for visual cues. Wilting, drooping leaves often signal thirst. However, check the soil first, as wilting can also occur from overwatering. Light-colored or dry soil on the surface is another indicator. Lift the planter; if it feels surprisingly light, the soil has likely dried out. For a more high-tech approach, a soil moisture meter can give you a precise reading.
Establishing a routine is helpful, but always let the soil's condition be your final guide. Different plants have different needs, so adjust your watering schedule accordingly. Proper drainage in your boxes is crucial to prevent root rot. With these simple techniques, you can master the art of watering and keep your urban garden thriving.
