Saving a Christmas cactus involves providing the right amount of light, water, and temperature. It needs to be placed in a bright area, but not in direct sunlight. It also needs to be watered only when the soil is dry, as overwatering can cause root rot. Finally, the temperature should be kept between 50-75 degrees Fahrenheit, as extreme temperatures can cause the plant to drop its flowers. Following these guidelines should help you save your Christmas cactus!
