Christmas Cacti (Schlumbergera) are beloved houseplants that are popular with Christmas Cactus bloom during the holiday season. Characterized by their tubular flowers, which can appear in shades of pink, red, white, and purple, these plants typically bloom from late November to January. Unlike other cacti, Christmas cacti thrive in bright indirect light and prefer a cooler environment, which helps to trigger a Christmas cactus to bloom.
Each year, it goes through a cycle of growth, blooming, and dormancy. During the growing season (spring and summer), the plant actively develops new leaves. From late November to January, Christmas Cactus becomes attractive for its vibrant blooms. Generally, Christmas Cactus bloom lasts around 4 to 6 weeks. After blooming, it enters a resting phase, where it requires less water and minimal care. With proper attention and care throughout the year, Christmas cactus can live for many years. This article will tell you how to better care for Christmas Cactus. From light, soil, watering frequency, temperature, and its favorite fertilizer, you can ensure your plant thrives and produces stunning blooms each holiday season.

Can a Christmas Cactus Live Outside?
A Christmas cactus can live outside, but it requires specific conditions or the Christmas Cactus become wilt. Ideally, it should be placed in a shaded or partially shaded area, as direct sunlight can scorch its leaves. The temperature should remain between 60°F to 70°F (15°C to 21°C), as these plants are sensitive to extreme heat or cold. Additionally, they need well-draining soil and should be protected from heavy rain or frost. If the outdoor environment aligns with these requirements, a Christmas cactus can flourish outside during the warmer months, but it should be brought indoors before temperatures drop in the fall.
How to Care For Christmas Cactus Inside?
As these vibrant plants bring color and joy during the holiday season, you may wonder how to care for Christmas Cactus to extend its lifespan, making it a long-lasting decor in your house.
Christmas Cactus Light
Proper light is essential for the health and blooming of a Christmas cactus. As these plants thrive in bright indirect sunlight, you can put them near a window with filtered light. Note that too much light can scorch the leaves but insufficient light can prevent blooming. Especially, during the winter months, when the cactus is preparing to flower, maintaining consistent light conditions is particularly important. If natural light is limited, consider using LED grow lights to provide the necessary illumination.

Christmas Cactus Soil
Using the right soil will help prevent root rot and promote healthy growth. The best soil for a Christmas cactus is a well-draining potting mix that retains some moisture without becoming soggy. Here are a few options:
Christmas Cactus Soil
- Cactus or Succulent Mix: Pre-packaged cactus or succulent potting mixes are specifically formulated to provide excellent drainage and aeration, making them a great choice for Christmas cacti.
- Custom Mix: You can create soil by combining standard potting soil with perlite or coarse sand in a 1:1 ratio. This mix enhances drainage while still retaining some moisture, which is beneficial for the plant.
- Orchid Bark: Adding orchid bark to your mix can further improve drainage and provide the aeration that Christmas cacti prefer.
Additionally, coffee grounds can also be beneficial for Christmas Cactus. They can provide a small amount of nitrogen and improve soil structure, enhancing drainage and aeration. Additionally, coffee grounds can help increase acidity in the soil, which some houseplants, including Christmas cacti, may appreciate.
Christmas Cactus Watering Frequency
How much water a Christmas cactus needs mainly depends on the season. During the growing season in spring and summer, you should water the plant every 2 to 3 weeks. This will allow the top inch of soil to dry out between waterings. As the plant enters its dormant phase in fall and winter during the blooming period, you can reduce watering to every 3 to 4 weeks. Monitor the soil moisture and ensure your Christmas cactus remains healthy and vibrant throughout the year.
How Often to Water Christmas Cactus
When watering Christmas Cactus, water the plant thoroughly until you see excess water draining out of the bottom of the pot. This ensures that the roots receive adequate moisture. Avoid letting the plant sit in standing water, as this can lead to root rot.
Christmas Cactus Temperature
There are slight differences between the best Christmas Cactus temperatures between the stage of growth and bloom. From Spring to Summer, Christmas cacti prefer to thrive in temperatures between 70°F and 80°F (21°C to 27°C). This warmth encourages healthy growth and development, allowing the plant to establish new leaves and prepare for blooming.
In contrast, during the blooming period, which occurs in late fall to winter, it’s beneficial to lower the temperature slightly. Ideal temperatures during this time are around 60°F to 70°F (15°C to 21°C). Cooler temperatures help stimulate flower bud formation, leading to a more abundant and vibrant display of blooms. If the temperature is not that ideal for growing Chrismas Cactus in winter, you can use a heat mat to maintain the growing temperature instead.
Christmas Cactus Fertilizer
During the growing season, the ideal ratio of water-soluble fertilizer is the N-P-K ratio of 10-10-10 or 20-20-20. This provides essential nutrients like nitrogen, phosphorus, and potassium. Instead, during the fall and winter months, particularly while the cactus is blooming, it’s best to reduce or stop fertilization to allow the plant to rest and conserve energy for producing flowers.

Where is the best place to put a Christmas Cactus?
The best place to put a Christmas Cactus is in a location that receives bright, indirect light. A spot near a window with filtered sunlight, such as one covered with sheer curtains, is ideal. This allows the plant to benefit from natural light without the risk of leaf scorch from direct sun exposure.
What triggers a Christmas Cactus to bloom?
The changes in light and temperature can trigger a Christmas Cactus to bloom. To encourage blooming, it requires a period of darkness for about six weeks prior to its expected flowering time. During this period, it should receive 12 to 14 hours of uninterrupted darkness each day, mimicking the natural shortening of daylight in late fall. Additionally, cooler temperatures, ideally around 60°F to 70°F (15°C to 21°C), during this time can stimulate bud formation. Proper care, including appropriate watering and fertilization, also plays a crucial role in ensuring a vibrant display of blooms during the holiday season.
How many times a year does a Christmas cactus bloom?
A Christmas cactus usually blooms once a year, between late November and January. While some varieties may have the potential to bloom again later in the year, it's less common, and the primary flowering event is generally celebrated during the winter months.
Why is my Christmas cactus blooming in October?
If your Christmas cactus blooms in October, it may be due to a few factors. One possibility is that the plant is experiencing environmental conditions that mimic its natural habitat, such as cooler temperatures and shorter daylight hours, which can trigger early blooming. Besides, if the plant has been exposed to stress—like changes in light or temperature, or irregular watering—it may respond by flowering sooner than expected.
