Christmas Cactus - Everything You Need to Know!

G et ready to jingle all the way with the stunning Christmas cactus (Schlumbergera bridgesii)!  In the middle of the winter season, when everything seems to be hibernating, this vibrant holiday plant bursts into bloom, spreading holiday cheer with its colorful flowers.

Native to the tropical rainforests of Brazil, your Christmas cactus belongs to the family Cactaceae and is often referred to by its other common names, including holiday cactus, winter cactus, and crab cactus. This unique tropical plant is named after Frédéric Schlumberger, a Frenchman who was an avid collector of cacti and succulents in the 19th century.

The Christmas cactus gained popularity because of its stunning and vibrant flowers, which typically bloom during the holiday season. Its flat, segmented leaves and cascading or trailing growth habit make it a visually striking addition to any space.

There are three types of holiday cacti: Thanksgiving cactus, Easter cactus, and Christmas cacti, each with unique characteristics. It is a particularly beautiful houseplant for the winter season, making it a festive addition to any home.

Its popularity can be attributed to its relatively easy-care requirements and its ability to thrive indoors. With proper care and the right conditions, this captivating succulent can bring joy and beauty to your home year after year. 

How to Get a Christmas Cactus to Bloom - Flowering Tips  

Your Christmas plants bloom approximately 12 weeks after planting under optimal conditions. Christmas plants will continue to bloom for a period of 4-6 weeks: making them a delightful and long-lasting addition to your indoor or outdoor garden. 

Blooming a Christmas cactus indoors

To encourage blooming, it's important to provide your cactus with the right conditions. 

• Make sure it gets plenty of bright, indirect light during the day. Avoid placing it in direct sunlight, as this can cause sunburn.
• During the fall season, give your cactus a period of uninterrupted darkness for about 12-14 hours each night. This mimics the natural light conditions that trigger blooming.
• Keep the soil slightly moist but not overly saturated, and avoid overwatering.

Blooming a Christmas cactus outdoors

If you're growing your Christmas cactus outdoors, it's important to consider the climate and growing conditions.  

• Make sure to place it in a spot that receives bright, indirect light but also some shade during the hottest parts of the day.
• Outdoor cacti benefit from a period of cooler temperatures (around 50°F to 55°F) for about 6-8 weeks in the fall. This temperature drop helps stimulate bud formation and blooming.
• Remember to protect your cactus from frost and bring it indoors if temperatures drop too low.

The Christmas cactus blooms in response to changes in light and temperature. As the days get shorter and the temperatures cool down, it signals the plant to produce, flower buds form, and eventually flowers.

Regardless of whether your cactus is indoors or outdoors, proper care is essential for optimal blooming. Ensure that the soil is well-drained and use a cactus-specific potting mix. Fertilize your cactus during the growing season with a balanced, water-soluble fertilizer diluted to half strength. Avoid fertilizing during the blooming period. Lastly, be patient! Christmas cacti typically bloom in response to changes in light and temperature, so it may take a bit of time for them to produce those stunning flowers. 

With these tips and minimal care, you'll increase your chances of getting beautiful blooms from your cactus, whether it's growing indoors or outdoors. 

Care of Christmas Cactus - Step-by-Step Guide 

Christmas cacti are incredibly easy to care for. In their native areas, they are epiphytic plants, which means they grow on trees and absorb moisture from the air. However, they can also thrive indoors with minimal care. Here's a step-by-step guide for easy Christmas cactus care: 

Christmas Cactus Watering

When it comes to watering your cactus, it's important to strike the right balance. Unlike most cacti, the Christmas cactus requires more watering; but they don't like to sit in water. Aim to water your cactus when the top inch of the soil feels dry to the touch. Use room temperature water and thoroughly saturate the soil, allowing any excess water to drain away. Avoid overwatering, as this can lead to root rot and other issues.  

During the growing season, which is typically spring and summer, your Christmas plant may require more frequent watering. Keep an eye on the soil moisture and adjust your watering schedule accordingly. However, it's important to reduce water in early fall and mid-October. This mimics the drier conditions of its native habitat and helps promote a healthy flowering period during the holiday season. 

Christmas Cacti Love Humidity

Another important aspect of watering your cactus is, humidity. These winter plants appreciate higher humidity levels, which can be achieved by placing a tray filled with water and pebbles beneath the Christmas cactus pot. As the water evaporates, it creates a humid microclimate around the plant. Alternatively, you can mist the leaves occasionally to provide a boost of moisture. Just be careful not to overdo it, as excessive moisture can lead to fungal issues. 

Christmas Cactus Light Requirements

The Christmas cactus is a popular houseplant; as it can handle bright, indirect light. It prefers a spot near a window where it can receive plenty of bright, filtered sunlight throughout the day. However, direct sunlight can be too intense for this plant and may cause sunburn on its leaves. So, it's best to avoid placing it in direct sunlight, especially during the hot summer months. 

If you're wondering how much light your cactus needs, aim for about 4-6 hours of light per day. During the growing season, which is typically spring and summer, providing longer daylight hours can help promote healthy growth and blooming. You can achieve this by placing your cactus near a window with bright, indirect light or by using artificial grow lights if natural light is limited. 

In contrast, during the fall and winter months, the Christmas cactus benefits from shorter daylight hours. So, if you want your cactus to bloom, it's important to provide it with around 8-10 hours of darkness at night. This can be achieved by placing it in a room that's not illuminated by artificial lights during the evening hours.

Keep in mind that it is adaptable when it comes to light conditions. It can tolerate lower light levels, but it may result in slower growth and fewer blooms. On the other hand, exposing it to too much bright light or direct sunlight can lead to leaf burn and damage. Finding that sweet spot of bright, indirect light and providing the right balance of daylight and darkness will help your cactus thrive and put on a stunning display of flowers.

The 3 Types of Holiday Cactus 

As a holiday plant, this hybrid Christmas cactus is often mislabeled and confused with other similar cacti by garden centers. The Thanksgiving and Easter cacti are often referred to as types of Christmas cacti because they share similar characteristics and are part of the same genus, Schlumbergera. These holiday plants are known for their ability to bloom zygomorphic flowers (two differently sized petal) around the holiday season, just like the Christmas cactus.  

Christmas cacti thrive in shaded or bright indoor pots and can be grown indoors anytime until summer. With proper care, it can grow quickly, reaching a two-foot spread in just a few years, with blooms at the beginning of each winter. All varieties can be planted indoors until summer, allowing for easy replanting or outdoor relocation. Here are the detailed differences between these: 

Choosing the Best Soil for Your Holiday Cactus

When it comes to choosing the right soil for your adorable Christmas cacti plant, you need to be careful! It's like picking out the perfect outfit for a date—you want to make sure everything is just right so there no surprises later on. 

You see, the amount of moisture in the soil can literally make or break your little green friend. Too much water and BAM! You've got root and stem rot faster than you can say "succulent." That's why we at Planet Desert have got your back with our specialized cactus potting mix. This organic substrate has mycorrhizae which helps your plants grow a healthy root system that makes all those spiky stems stand up tall and proud.  As an okay alternative, you can create your own potting mix by combining equal portions of perlite, coarse sand, and good natural potting soil.  

If you prefer a DIY approach, you can create your own soil mix by combining equal parts of regular potting soil, perlite, and coarse sand. This mixture will help mimic the well-draining conditions that Christmas cacti prefer. Just be sure to avoid using heavy garden soggy soil or mixes that retain too much moisture, as this can lead to root rot and other issues. 

Additionally, it's worth mentioning that the cactus is not too picky when it comes to soil pH. It can tolerate slightly acidic to slightly alkaline soil, with a pH range of around 5.5 to 7.0. So, as long as you provide a well-draining potting mix that allows air to reach the roots and prevents waterlogging, your cactus should be happy and healthy! 

How & When to Fertilizer Your Christmas Cactus 

When it comes to fertilizing your Christmas cactus, it's important to provide it with the right nutrients to support healthy growth and vibrant blooms. A balanced, water-soluble fertilizer formulated specifically for Christmas cacti. Look for a fertilizer with an NPK ratio of around 5-10-5. 

During the active growing season, which typically occurs in spring, you can fertilize your cactus once a year. Dilute the fertilizer according to the package instructions and apply it to the soil around the base of the plant. Be careful not to over-fertilize, as this can lead to salt build-up and damage the roots. Remember, it's always better to under-fertilize than over-fertilize. 

Withhold fertilizer or stop fertilizing altogether, during the winter. This mimics the plant's natural cycle and allows it to rest and prepare for blooming. During this time, it's important to focus on providing the right environmental conditions, such as cool temperatures and reduced watering, to encourage flower bud formation. 

In addition to regular fertilizer, you can also give your cactus a boost by using organic alternatives. For example, you can use a diluted solution of compost tea or worm castings to provide natural nutrients to the plant. These organic options can help improve soil fertility and overall plant health without the use of synthetic chemicals. 

Hardiness Zone & Temperature 

When it comes to indoor temperature, Christmas cacti prefer a cozy, humid environment without too much light. They thrive in temperatures between 60°F and 70°F during the day, with slightly cooler temperatures at night. This range mimics their natural tropical habitat and helps promote healthy growth and blooming.

If you live in USDA zone 10-12; you can grow Christmas cactus outdoors. These zones are characterized by mild winters and warm temperatures. If you live in a colder region, you can still enjoy the beauty of the cactus by growing it indoors or in containers that can be brought indoors during colder months. 

 As a popular indoor plant, the cactus is loved for its vibrant blooms and easy-care nature. It adds a festive touch to any home during the holiday season. With proper care, these holiday cacti grow indoors, even in regions where the climate may not be suitable for outdoor growth. They make excellent houseplants, brightening up living spaces with their colorful flowers and unique foliage. 

Additionally, Christmas cacti can adapt to average indoor humidity levels. However, they appreciate slightly higher humidity. You can increase humidity around the plant indoors by misting its leaves with water or placing a tray filled with water and pebbles beneath the pot. This helps create a more humid microclimate, which the cactus will appreciate. 

So, whether you choose to grow your Christmas cactus indoors or in a suitable outdoor environment, maintaining the right temperature and humidity levels is key to its success. Enjoy the beauty of this popular indoor plant and its stunning blooms! 

Quick Annual Care Schedule for Christmas Cactus 

Enjoy the beautiful blooms of your cactus during the flowering season! 

Remember, these care guidelines are general recommendations, and it's essential to observe your cactus's specific needs and adjust care accordingly. 

Christmas Cactus Pruning  

When it comes to pruning your Christmas cactus, it's best to do it after the blooming period, typically in late winter or early spring. Start by examining the plant and identifying any dead, damaged, or overgrown stems. Using clean and sharp pruning shears or scissors, carefully trim these stems back to the base of the plant. This will help promote new growth and maintain a more compact and tidy appearance. Remember to prune selectively and avoid removing too much of the plant at once to prevent stress.  

In addition to removing dead or damaged stems, you can also shape your cactus through selective pruning. If you notice any stems that are growing unevenly or becoming too leggy, you can trim them back to encourage branching and a more balanced growth pattern. Additionally, if you want your cactus to be bushier, you can pinch off the tips of the stems. This will stimulate the growth of lateral branches and result in a fuller plant. Just be sure not to go overboard with pruning, as it's important to maintain a good balance between growth and overall plant health. 

Remember, pruning is a personal preference, and you can adjust the level of pruning according to your desired shape and size for your cactus. 

Propagating a Christmas Cactus 

So, to increase your chances of success, aim to propagate your cactus during the spring or early summer, when it's in its growing phase and not actively blooming. This will give your cuttings or seeds the best chance to take root and thrive. 

Propagating Christmas Cactus by Stem Cuttings:

1- Select a healthy segment of the Christmas cactus stem, around 3-4 segments long.

2- Allow the cutting to dry and callus for a few days. This helps prevent rotting.

3- Prepare a well-draining soil mix by combining equal parts potting soil and perlite or sand.

4- Place cuttings in lightly moistened soil, three stems in a 4-inch pot, and five stems in a 6-inch pot, and expect roots to form within two to three weeks.

5- Keep the soil lightly moist, but avoid overly wet soil or overwatering, as it can lead to root rot.

6- Place the cutting in a warm and bright location, but avoid direct sunlight.

7- After a few weeks, roots should start to develop, and after a few notches, the new plant will begin to grow.

Before putting the stems in the ground, you have the option to root them in water. Place the jar in an indirect light window after submerging the cut end in one to two inches of filtered water. The stems are ready to be planted in potting soil after a few weeks if their roots are at least one or two inches long. 

Propagating Christmas Cactus by Seeds:

1- Start by collecting ripe seeds from the fruit of your Christmas cactus.

2- Clean the seeds by removing any pulp or debris and allowing them to dry for a few days.

3- Prepare a well-draining soil mix by combining equal parts potting soil and perlite or sand.

4- Plant the seeds in small pots or seed trays, lightly covering them with a thin layer of soil.

5- Keep the soil consistently moist, but not waterlogged by misting it or using a spray bottle.

6- Place the pots or trays in a warm and bright location, but avoid direct sunlight.

7- Be patient, as germination can take several weeks or even months. Once the seedlings have grown a bit, you can transplant them into individual pots.

Remember, propagating plants can be a fun and rewarding process, but it requires some patience and care. Give it a try, and you might end up with new cactus plants to enjoy or share with others! 

Repotting Christmas Cactus 

When you do decide to repot, remember to choose a slightly larger pot and use well-draining soil. This way, your cactus can continue to grow happily and show off its beautiful blooms. 

Overwintering Christmas Cactus 

Overwintering a Christmas cactus is an important part of its care, especially if you live in a region with cold winters. During the winter months, these cacti appreciate a period of rest and lower temperatures. To overwinter your Christmas plant, you can place it in a cool room with temperatures around 50-60°F. It's important to reduce watering during this time and only water when the soil feels dry. This helps simulate the natural conditions that the cactus would experience in its native environment. By providing the right conditions, you can help your cactus stay healthy and prepare for another year of beautiful blooms. 

Common Pests & Diseases of Christmas Cactus 

There are indeed more pests that can bother our Christmas cacti, such as mealybugs, spider mites, flower thrips, and fungus gnats.

• Mealybugs are those pesky white, cottony critters that can suck the sap from the plant. To treat them, you can use insecticidal soap or wipe them off with a cotton swab dipped in rubbing alcohol.
• Spider mites are tiny red or brown specks that can cause discoloration and webbing. You can try using a miticide or gently washing the leaves with water to control them.
• Flower thrips can damage the flowers and leaves, and you can use insecticidal soap or neem oil to combat them.
• Fungus gnats are those annoying little flies that hover around the soil. To get rid of them, you can let the soil dry out between waterings and use sticky traps to catch the adult gnats. It's important to keep an eye out for these pests and take action promptly to keep your cactus healthy and happy!
• Overwatering plants can lead to fungal illnesses. In order to avoid fungal infections, avoid overwatering tropical plants. Two prevalent cactus fungi that can cause stem rot are Fusarium and Phytophthora.

Brown patches appear near the soil line of the stem due to fusarium stem rot. If detected in time, cactus may recover from the fusarium, although it's usually not a good chance. If the soil around the plant is very moist, let it dry out before applying a fungicide in accordance with the directions on the label. The stem at the soil level appears moist or water-soaked due to phytophthora stem rot. Phytophthora can be lethal. 

Avoiding Problems with Christmas Cactus Health 

Christmas Holiday cacti are sensitive to temperature and humidity, hardy above freezing temperatures but require ideal conditions for lush flowering during the holidays. Here are some points to help you avoid problems with your Christmas cactus's health. 

• Root Rot: Prevent root rot by using well-draining soil specifically formulated for cacti. Avoid overwatering and allow the soil to dry out between waterings. If you suspect root rot, gently remove the affected parts and repot your cactus in fresh, well-draining soil.
• Distorted Growth: Ensure your cactus is getting the right amount of light. Too much direct sunlight on flat stem segments of tropical cactus can lead to stunted or misshapen growth, while insufficient light can cause elongated stems. Find a bright spot with indirect light for your cactus.
• Leaves Turning Red or Pink: This can be a natural response to changes in light or temperature. However, sudden or excessive color changes could indicate stress. Maintain consistent light and temperature conditions for your cactus to minimize color variations.
• Yellowing of Leaves and Wilting: Overwatering is often the culprit behind yellowing and wilting leaves. Make sure to let the top inch of soil dry out before watering new plants again. Also, ensure your pot has proper drainage to prevent water from pooling at the roots.

Remember, each cactus is unique, so it's essential to observe and adjust care based on its individual needs.
