why are the leaves on my christmas cactus limp

The limpness of the leaves on your Christmas cactus is likely due to the plant not receiving enough water. Christmas cacti need consistent moisture to thrive, so it's important to water them regularly. Try giving your plant a deep drink, allowing the water to soak into the soil. If the leaves still don't perk up after a few days, you may need to increase the frequency of watering. Remember, Christmas cacti prefer evenly moist soil but don't like to sit in wet conditions.
