Depending on your home's temperature, humidity, and specific conditions, you may need to water your Goeppertia burle-marxii approximately once or twice a week. However, adjusting the watering frequency based on the plant's needs is essential. Always check the soil's moisture level before watering to ensure you're providing adequate moisture without overwatering.
