Growing seeds from your own plants is usually a lot of fun, and right now, during the winter, your Schlumbergera cacti, sometimes referred to as holiday, Christmas, or Thanksgiving cactus, may be in full bloom.
It’s the ideal time to have fun pollinating the flowers on your Schlumbergera cactus while they are all gorgeously flowering to see if you can get seeds. The process of pollinating the flowers is really simple, and I’ve included a few films I’ve created for my Cacti & Succulent You Tube channel called Desert Plants of Avalon where I demonstrate the process in detail.
All you need is a Schlumbergera cactus that is in bloom, preferably with at least two flowers on it. In my personal experience, I have always found it more successful to cross pollinate the flowers on the same plant or if you have two different Schlumbergera that are flowering at the same time, for example, a red flowering one and a pink flowering one.
Although I have had wonderful luck pollinating Schlumbergera blossoms and have typically had seed when I have done so, I have discovered that many of my more recent Schlumbergera purchases have not been successful in producing fruit and seeds for me. I’ve heard that some of the more recent hybrids on the market are more difficult to pollinate for seed, but I don’t yet have enough proof to support that. Please let me know if you have had success pollinating the flowers on the more recent Schlumbergera hybrids that are currently available.
If you have only one flower, it is best to take the pollen from that flower and gently dab it onto the stigma of the other flower or flowers. If you have more than one flower, it is best to take the pollen from the one flower and gently dab it onto the stigma of the other flower or flowers. All you need to do is use a clean, tiny brush, such as a tiny paintbrush, lip brush, or q tip cotton bud, and load the pollen from the flower.
Here is a picture of one of my Schlumbergeras, Schlumbergera ‘Golden Charm,’ in bloom with the bright pink stigma hanging out. The stigma is the portion of the flower that hangs out almost like a tongue, hehe. Hopefully, this will demonstrate what the stigma looks like.
Here is a step-by-step video I prepared on how to pollinate Schlumbergera Christmas and Thanksgiving Cactus flowers for my cactus and succulent You Tube channel, Desert Plants of Avalon:
Simply dab the pollen from the one flower or flowers from one Schlumbergera cactus onto the other stigma on the other cactus flower if you wish to cross-pollinate two distinct flowering Schlumbergera cacti, such as a white one crossed with a red, pink, or orange one.

If pollination was successful, the base of the flower where it emerges from the end of the leaf segment will start to swell up and turn a darker green color within a few days. If not, the blooms will naturally begin to droop and dry up before falling off ( see photo below )
The fruit may not fully mature for several weeks, months, or even a whole year. When the fruit is ready to be harvested for its seeds, the fruit pod will typically become very soft and frequently turn a dark crimson color, resembling a delicious tiny berry.

Once the seeds have been harvested, it is time to sow them. Growing these plants from seeds rather than cuttings takes much more time, but it is also far more enjoyable and fulfilling.
Cacti can be grown from seed in a variety of ways, but I prefer to grow my seeds in pots that are then put into “baggies.” This keeps the seeds and young seedlings moist at all times without having to worry about the soil drying up. Depending on their size, I remove them from the clear bags in around 3 to 6 months and treat them like young seedlings, ensuring sure the soil is always moist but not waterlogged.
All cacti seeds should be sown in the spring, but if you have grow lights and additional warmth, you can start sowing them at any time of the year.

A Christmas cactus needs to be pollinated, right?
The Christmas cactus (Schlumbergera x buckleyi), also referred to as the Thanksgiving cactus, is an epiphytic succulent cactus that can survive in plant hardiness zone 9 of the United States Department of Agriculture. The Christmas cactus, a seasonal favorite, has trumpet-shaped flowers with white, orange, pink, or red petals that are naturally pollinated by birds but can also be done by hand. Even though certain Christmas cacti kinds are self-fertile, hand-pollination will produce more diverse offspring. For successful pollination, you will need a minimum of two Christmas cacti, ideally of different hues.
The stigma and the anther are the two reproductive components that may be seen on flowers. A Christmas cactus’ scarlet stigma sticks out from the middle of the blossom. The stigma is situated adjacent to the pollen-coated anther, which is affixed to the end of a different tube known as a filament.
The day after the flower opens, gently rub one Christmas cactus’ anther with a cotton swab. Verify if some pollen has stuck to the cotton swab. On the second Christmas cactus, rub the stigma’s sticky top with the pollen.
How are Christmas cactus seeds obtained?
My cactus is currently in bloom. What will happen to this fruit from last year going forward? The wilted blossom is still attached, as you can see.
Your instinct was right—there are seeds within. According to one source, you should snip the thin end of mature (bright pink) pods, squeeze the pulp into some sand in your palm, then rub the seeds about to separate them (seeds should be chocolate brown to black). In small pots, scatter over moist soil mixture (1 part perlite to 3 parts peat). Keep moist and shaded. It takes seeds about a week to grow.
Why doesn’t the Christmas cactus bloom?
Due to its short day length, the Christmas cactus cannot blossom due to drought stress or excessive light exposure. Christmas cacti are adapted to wet, frequently rainy jungles. If the conditions are dry or there are too many hours of sunshine during bloom production, it does not flower.
I’ve listed here a few other reasons that can stop the Christmas cactus (Schlumbergera) from flowering:
Continue reading to learn why your Christmas cactus isn’t blossoming and the finest methods for putting remedies in place so that it can produce blossoms.
Can a Christmas cactus be started from a cutting?
Christmas cacti are relatively simple to grow from seed. Cut segments of one to four and leave them to dry out for two to four days in a cool, dry location. Plant a sand/peat mixture an inch deep in fresh soil. Prior to the development of roots or new growth, water sparingly.
When will Christmas cactus cuttings begin to bloom?
Whether they have a green thumb or not, many Christmas Cactus owners have had success in maintaining their plants, but getting them to bloom is frequently a different story. Christmas cacti are renowned for requiring extremely precise maintenance in order to produce blossoms.
Christmas Cacti often bloom around the holidays, as their name suggests. Once in flower, you’ll have a total of four to six weeks to enjoy the lovely blooms.
You must first permit your Christmas Cactus to go into dormancy in order to promote blooming. Around October or November, you’ll start to reduce the amount of water you feed your plant. You don’t want to fully cease watering, in contrast to other animals that hibernate.
Instead, water your Christmas cactus less regularly, but longer. The soil should continue to be just barely damp. This is essential because, if your plant already has buds, overwatering or underwatering can make them fall off.
The next step is to ensure that your Schlumbergera receives 12 to 14 hours of darkness each day. Darkness is more essential for the growth of flower buds the warmer the nighttime temperatures. The typical bright, indirect light is fine during the day.
You must keep your Christmas Cactus away from drafts during this time. Extreme temperature swings have the potential to shock the plant and cause the flower buds to fall off.
Before buds start to form, you’ll need to maintain your Schlumbergera’s care for around six to eight weeks after you start doing so. You’ll need to continue your therapy once the buds have formed for another 12 weeks or more before the first flowers start to bloom.
If all went according to plan, you’ll soon be savoring a tropical delight during a typically chilly time of year. This is a fantastic chance to pollinate your plants if you’re interested in growing Christmas Cactus from seeds. These plants are naturally pollinated by insects and birds, but they are also simple to pollinate by hand.
Can a cactus be pollinated by its own pollen?
Because cactus blossoms don’t persist long, wind or insect pollination is more challenging. Cacti are unable to produce fruits and seeds without pollination. When you self-pollinate cacti, you have complete control over the outcome, whether you’re aiming to develop a novel hybrid or develop a particular cactus variety. Hand pollination is the only way to guarantee that the two types you are attempting to cross pollinate, as hybrid pollination does not always result in the production of viable seeds.
Once flowers start to develop, put your two cactus plants next to one another. You can try to create a hybrid with the same type of cactus or with two different types by crossing them. Choose which plants you want to pollinate if the cacti are outside. Although more pollen can be transported when the plants are close to one another, this is not necessary.
To get ready, soak your brushes in rubbing alcohol to get rid of any filth or bacteria, then let them air dry.
Check your flowers every day for pollen. The stamens, which are frequently fluffy threads encircling the part of the flower where the stigma are located, are where pollen grows. The flower’s petals show a thin dusting of pollen.
The second cactus flower’s stigma should be painted with pollen. The stigma, which resembles tiny fingers in appearance, are thicker than the stamens. In order to help them capture the pollen, the tops are typically slightly open and sticky. Wait another day before attempting to pollinate if the stigma tops are not yet open to give them time to do so.
Wait for the brush to dry after cleaning it. The second cactus bloom should be used to complete the process, with the pollen being applied to the stigma of the first cactus after dusting the stamens for pollen.
Nylon stockings should be placed over both cacti to stop pollination by other cactus plants. Only if you want to try and influence the kind of seed the plants produce is this important. If your primary objective is to induce the cactus to produce fruit or seeds, keep the plants exposed to attract insects and wind, which will aid in additional pollination.
Cacti are they self-fertile?
There is no need for even two blossoms if a species is self-fertile. Some plants may self-pollinate on their own without any help, while others require an intermediary to move pollen from the anthers to the stigma. For instance, even if only one flower opens at a time, my Echinopsis ancistrophora always sets seed when it blooms outdoors because hover flies visit it. When I took it indoors to bloom, it occasionally failed to produce pollen (and the flowers lasted longer).
How are cactus seeds obtained from flowers?
The cactus blossoms produce seeds. If you want to try collecting them, pick the faded blooms and put them in a tiny paper bag. As soon as the blossoms have completely dried out, you can find the seeds. As many seeds are sold online, you can also buy them. Make sure you’re buying from a reliable source by checking. You want seeds that are healthy and likely to grow.
The seed must be awakened from its dormancy before it may sprout. When learning how to plant cactus seeds successfully, there are several ways to eliminate the dormancy factor that are crucial.
Nick the seed’s protective hard shell. Some types of seeds require soaking before planting. One of the seeds with a hard seed coat is opuntia, which will germinate more quickly if the seed surface is scratched and wet. The cold stratification procedure is advantageous for opuntia seeds as well. Follow the steps in this order for the best seed growth:
- With sandpaper, a little knife, or your fingernail, scarify the seed by creating a tiny opening.
- Spend a few days soaking in warm water, changing it every day.
- Put the soil in the freezer or somewhere cool to stratify for 4 to 6 weeks.
Following these procedures, sow your seeds in a moist, well-draining seed starting mix, and then cover them. Avoid planting deeply. Some can simply be placed on top of the soil, like the golden barrel cactus. For others, all that is required is a light soil covering.
Locate away from the sun yet in a bright area. Sunlight with filters is acceptable. Cactus can survive in dry climates, but it needs sufficient humidity to germinate. The soil must be kept wet but not drenched. In a few weeks to a few months, seeds will begin to sprout. A virtue is patience.
According to information on growing cactus seeds, above-ground development takes shape before the root system does, therefore constant hydration and high humidity are required until roots have fully formed. This typically continues until the plant has filled the starter container. Then you can transfer the cactus you started from seed.
