You should water a snake plant only when its soil is completely dry. During the growing seasons of spring and summer, this typically means watering about once every 1 to 2 weeks, but it can vary depending on light, temperature, and humidity conditions. In cooler months like fall and winter, reduce watering to once every 3 to 6 weeks, as the plant's growth slows and it requires less moisture

. Key points to consider:

• Always check the soil moisture by feeling the top 1-2 inches; if dry, it's time to water

• Water deeply but sparingly, allowing excess water to drain to avoid root rot

• Snake plants store water in their leaves, so they tolerate drought well and prefer to be underwatered rather than overwatered

• Environmental factors like light (more light means more water), temperature (warmer means more water), humidity (drier means more water), soil type, and pot drainage affect watering frequency

• Watering with room temperature, filtered, or rainwater is ideal to avoid chemical buildup from tap water

In summary, a good general schedule is watering every two weeks during warm months and less frequently in winter, always ensuring the soil has dried out completely before watering again
