How to Divide a Christmas Cactus for Propagation
How to Divide a Christmas Cactus?
To divide a Christmas cactus, wait for a period of dormancy after the flowers have fallen off.
Gently remove the entire root ball from the pot and separate the plant into distinct sections.
Cut any tangled roots with a clean knife and transplant any stem with attached roots.
Use the “propagation by cutting” method on stems without roots to stimulate root growth.
Plant the sections in small pots with fresh cactus or succulent soil, allowing for an extra inch of soil on all sides.
Water well immediately after replanting, and repot the cactus every few years to promote growth.
Dividing can be done by cutting through the thick roots with a sharp knife and replanting in a well-drained potting mix.
Alternatively, new cacti can be started from cuttings by sinking half of each stem in sterile soil, keeping them in a warm location without direct sunlight and keeping them moist.
Within two to three weeks, new roots should appear, and the cactus should become root-bound before being transplanted into a bigger pot.

Did You Know?
1. Despite its name, the Christmas cactus is not actually a cactus, but rather a type of succulent originating from the tropical rainforests of Brazil.
2. The Christmas cactus, also known as Schlumbergera, is a unique plant that blooms during the winter months, making it a popular choice for Christmas decorations.
3. You can propagate a Christmas cactus by simply snipping off a segment of one of its stem segments and placing it in a pot with well-draining soil. In a few weeks, roots will form and a new plant will start to grow.
4. If you place your Christmas cactus in complete darkness for about 14 hours a day for a few weeks, it can help stimulate blooming during the holiday season.
5. The Christmas cactus is not only beautiful but also has air-purifying qualities, as it helps remove toxins from the environment, making it a beneficial addition to your home or office.
Dividing A Christmas Cactus During Dormancy
The best time to divide a Christmas cactus is during a period of dormancy, which occurs after the flowers have fallen off. This is usually in the late winter or early spring. Dividing the plant during this time gives it the opportunity to recover and establish new roots before the next blooming season.
During the dormancy period, the cactus is not actively growing and is less likely to be stressed by the division process.
To begin dividing a Christmas cactus, gently remove the entire root ball from the pot. This can be done by turning the pot upside down and tapping on the bottom or squeezing the sides of the pot to loosen the soil.
Once the root ball is free, carefully separate the plant into distinct sections. Some sections may have individual stems, while others may be clusters of stems. The goal is to divide the plant into healthy and well-established sections that can thrive on their own.

Dividing during this period allows for recovery and root establishment before the next blooming season. Gently remove the root ball from the pot and separate the plant into distinct sections. Divide the plant into healthy sections that can thrive independently.
Techniques For Dividing A Christmas Cactus
When dividing a Christmas cactus, it’s important to handle the plant with care to prevent damage to the roots. If the roots are tightly woven together and cannot be separated by hand, use a clean, sharp knife to cut through them. Be sure to sanitize the knife with rubbing alcohol or a household disinfectant to minimize the risk of introducing pathogens.
After cutting through the entangled roots, transplant any stem sections that have attached roots into separate pots. This will help ensure that the new sections have a good foundation for growth. For stems without roots, you can use the propagation by cutting method to stimulate root growth. Simply cut a stem section and plant it in a rooting medium, such as water, moist vermiculite, or a peat/perlite mixture.
Propagating A Christmas Cactus Through Cuttings
Propagating a Christmas Cactus through Stem Cuttings
A great method for propagating a Christmas cactus is through stem cuttings. This involves taking a section of the stem and encouraging it to develop roots on its own. Cuttings can be obtained by breaking the stem at the joint between the phylloclades, which are the flat leaf-like segments of the cactus.
To successfully root the cuttings, follow these steps:
- Sink half of each stem in a sterile potting soil.
- Place the cuttings in a warm location with indirect sunlight.
- Keep the soil moist.
- After two to three weeks, new roots should begin to appear.
Remember to closely monitor the cuttings, ensuring they receive sufficient moisture and warmth for successful root development.
Transplanting Divided Sections Into Small Pots
Once you have divided the Christmas cactus into separate sections, it’s time to transplant them into individual pots. Choose small pots that provide enough room for the roots to grow, allowing for an extra inch of soil on all sides. This will give the new sections space to establish themselves without feeling cramped.
Before planting the divided sections, make sure to shake off the old soil from the roots. This helps remove any compacted dirt and allows the roots to have better access to fresh potting soil. Use a cactus or succulent potting soil that provides good drainage and aeration. Place the divided sections in the pots, ensuring that the roots are covered with soil and the stems are supported.
After transplanting, water the newly potted Christmas cactus well to settle the soil and hydrate the roots. This initial watering helps the plant adapt to its new environment and promotes healthy growth.
Repotting A Christmas Cactus For Growth And Health
To promote growth and maintain the health of a Christmas cactus, it is highly recommended to repot the plant every few years. Repotting allows the roots to have more room to grow and replaces the old potting soil with fresh soil that provides better aeration, drainage, and nutrients.
According to the Clemson Cooperative Extension, repotting a Christmas cactus is necessary approximately every three years. When repotting, it is important to carefully remove the cactus from its current pot, being mindful of the root system. Gently shake off the old dirt from the roots and replant it in a well-drained cactus potting mix.
After repotting, continue to care for the Christmas cactus by providing the appropriate amount of water, light, and temperature. Regularly monitor its growth and health, and adjust the care as needed.
Growing A New Christmas Cactus From Stem Cuttings
If you only have one stem section from a Christmas cactus, you can still grow a new plant from it. By placing the bottom of the stem in water or a moist rooting medium, such as vermiculite or a peat/perlite mixture, you can stimulate root growth and establish a new cactus.
For faster root growth, you can also dip the stem in water and then rooting hormone before placing it in damp, coarse sand. Rooting hormone contains auxins that can encourage root development. Keep the stem in a warm location without direct sunlight and ensure that the rooting medium stays moist.
Check for root growth after approximately two weeks. Once roots have developed, the new Christmas cactus can be transplanted into a bigger pot. This allows the plant to establish itself and continue growing.
Dividing a Christmas cactus can be a rewarding experience that allows you to propagate the plant, fill your home or office with flowers, and even give them as gifts. By following the proper techniques of dividing, propagating through cuttings, transplanting, and repotting, you can ensure the health and growth of your Christmas cactus for years to come.
Frequently Asked Questions
Can I propagate a broken piece of Christmas cactus?
Absolutely! Propagating a broken piece of Christmas cactus is indeed possible. Simply take a cutting of the broken segment, ideally consisting of one to four segments, and allow it to dry in a cool and dry location for a couple of days. Once dried, plant the cutting approximately one inch deep in a fresh soil mixture, preferably one which incorporates sand and peat. Initially, water the cutting sparingly until either roots or new growth emerge, and then begin watering it regularly as you would with a mature plant. With patience and care, your broken Christmas cactus segment has the potential to flourish into a thriving new plant.
Can Christmas cactus grow from cuttings?
Yes, Christmas cacti can indeed grow from cuttings. It is a straightforward and simple process. By carefully removing sections of the plant made up of 2 to 5 flattened stem segments and cutting or pinching them off at a joint, you can easily propagate new Christmas cacti. Allowing the cut or pinched ends of the cuttings to callus overnight is also crucial in ensuring successful growth.
How do you shape a Christmas cactus?
To shape a Christmas cactus, start by gently twisting the stems at the narrow joint between leaf segments. If the stems are thicker, you can use a knife or pruners for a clean cut. If you want to give the plant a specific shape, lightly prune a few segments to achieve your desired form. Additionally, if you wish to control the size of the plant, it is recommended to remove up to one-third of the plant each year. This will help maintain a more compact and manageable size.
How do you divide cactus plants?
Dividing cactus plants requires a careful and systematic process. Begin by laying out newspapers to prevent a messy workspace. Next, carefully remove the plant from its pot, taking care not to damage the roots. Before dividing, determine how many plants you want to produce from the division. Gently separate the root ball into individual sections, ensuring that each division has roots, a healthy stem, and leaves or shoots. Finally, pot each division in a clean pot with proper drainage to promote healthy growth. Following these steps will ensure successful division of cactus plants.
