Christmas Cactus Watering 101: A Simple Guide

Understanding the Needs of Your Christmas Cactus

The Christmas cactus, known scientifically as Schlumbergera bridgesii, is a popular houseplant treasured for its colorful, tubular flowers that bloom right in time for the holiday season. Originating from the tropical rainforests of Brazil, these cacti are actually quite different from their desert relatives and have specific watering needs that must be met to keep them thriving. A well-hydrated Christmas cactus will reward you with a spectacular display of blooms, but it is also very sensitive to over-watering which can lead to root rot and other issues.

When to Water Your Christmas Cactus

Determining the right time to water your Christmas cactus is a vital component of caring for this plant. Unlike many other types of cacti, the Christmas cactus prefers the soil to be slightly moist at all times; however, it does not fare well in waterlogged or dry soil. The best practice is to check the moisture level of the soil before watering. You can do this by simply touching the top inch of the soil with your fingers. If the soil feels dry, it’s time to water. During active growth periods, usually in the spring and summer, watering may be needed more frequently.

Seasonal Watering Considerations

The Christmas cactus has different watering needs depending on the time of year and its growth cycle. During the growing season (spring and summer), water the plant more often, allowing the topsoil to dry out between waterings. When fall arrives, reduce the frequency of watering to encourage blooming. In the winter, after the blooming period, water sparingly, maintaining just enough moisture to prevent the soil from completely drying out.

How to Water Your Christmas Cactus

When you water your Christmas cactus, it’s important to do so thoroughly. This means watering until excess water begins to drain out of the bottom of the pot. Be sure to empty the saucer beneath the pot after watering to ensure the plant is not left sitting in standing water. Using room temperature water can help avoid shocking the plant’s root system, which can be sensitive to sudden changes in temperature.

The Soak and Dry Method

A recommended method of watering your Christmas cactus is known as the soak and dry method. This involves allowing the plant to soak up water from the bottom. To do this, place the pot in a sink or container filled with a couple of inches of water and let it sit for about 30 minutes. Make sure the water can reach the drainage holes at the bottom of the pot. After the time has elapsed, remove the pot and let it drain thoroughly.

Signs of Improper Watering

Being aware of the signs of over and under-watering can help you adjust your care routine for a healthier Christmas cactus. Over-watering can lead to swollen, limp, or discolored leaves and stem segments, while under-watering may cause shriveled leaves and a lack of flowering. Adjusting your watering schedule according to the season, plant growth, and humidity conditions will help prevent these issues.

The Right Water for Your Christmas Cactus

The type of water you use can also affect the health of your Christmas cactus. Tap water can be used, but if it is highly chlorinated or contains high levels of minerals, it may be beneficial to let the water sit for a day before using it or to use filtered or distilled water instead to avoid potential buildup of harmful substances in the soil that could damage the plant.


Watering your Christmas cactus properly is a delicate balance that requires attention and understanding of the plant’s needs. By following the watering guidelines provided, paying attention to the moisture level of the soil, and recognizing the signs of watering issues, you can maintain a healthy, blooming Christmas cactus that will brighten up your home every holiday season.
