If your Christmas cactus is dropping buds, read this guide to know the reasons and solutions to have abundant festive blooms this season!
Are you looking for reasons why your Christmas cactus drops buds every year and flowers less prolifically, no matter what fertilizer regime you follow? Well, keep reading for the answers below.
If your Christmas cactus is dropping buds, read this to know the reasons and solutions!
1. A Change in the Environment
It is quite a sensitive houseplant that does not do well in sudden environmental changes or when transferring to new surroundings.
In such a case, move back to its earlier location and observe if it brings any changes. Or else, let it acclimate to the new location slowly, and do not overdo or change any other care routine. Let it simply take time to adapt to the new environment!
2. Irregular Watering
Unlike other cacti, this cactus has different watering needs and is also very clingy when it comes to inconsistency! Yes, so if you have made a change in its watering routine or if you are not using room-temperature water to feed it, then it is likely to cause bud dropping in your Christmas cactus.
So, do not try to experiment with inconsistent watering, especially not during its blooming period. It surely is not a fan of keeping it thirsty for a long time!
You can always check the top layer of the soil before moistening it again, as too frequent watering can lead to root rot, and too infrequent watering can induce bud drop.
3. Inadequate Light Conditions
Lighting has a big role to play during the Christmas Cactus’s blooming period. It requires a period ranging from 12 to 14 hours of total darkness to force bud formation from September to the end of November.
You will also need to provide it with bright light for 7-8 hours for the rest of the time. Once buds have set and begun to open, the long darkness period can end.
So, if you keep your plant in a place where it receives less light even after bud formation, then definitely this will take a toll on your Schlumbergera! You will see the buds falling, and the flowers won’t open up well during holiday season.
The trick is to keep it in a place where it receives a certain period of indirect sunlight during the day.
Pro Tip: If you still have a concern that the light is not enough, you can always use grow lights.
4. Temperature Fluctuations
The holiday plant blooms in winter, and the use of radiators is common during these cooler months. This leads to fluctuations in temperature and an increase in dry warm air in your home.
If you are keeping your plant anywhere near these vents, it will eventually cause bud dropping and dry, shrivelled foliage as well.
A simple solution to this is to keep your plant far away from the vents to avoid dry air. You can use a thermostat to maintain a uniform temperature, mostly below 90°F (32°C), because anything above this can result in bud dropping.
Pro Tip: Try keeping it near a window, with other plants, or a hallway where there is much open space to balance the air conditions; however, ensure that your plant’s leaves are not touching the windowpane.
5. Insufficient Humidity
Again, the use of heaters and radiators can cause excessive dry air in your home, which is the biggest reason for insufficient humidity.
Since Christmas cactus loves moist air due to its rainforest origins, the imbalance in humidity leads to bud drops!
Try to balance or maintain a good percentage of humidity inside, and this is not so difficult to accomplish. Just place a saucer filled with pebbles, stones, and water, and keep it near or under the plant. The water that evaporates from this saucer will moisten the air.
You can also place a humidifier near your Christmas cactus; it’s also quite inexpensive.
6. Pest Infestations
After ensuring all the right conditions, if you still see buds dropping, it can be due to pesky invaders. Pest infestations like aphids or mealybugs can severely hamper the delicate buds from developing.
Keep an eye out for white coating on segments and buds, and treat your Christmas cactus with one of these remedies. The best remedy is to use organic pesticide sprays like Neem oil to avoid side effects and speedy recovery.
7. Improper Potting Mix
Too much or too little fertilizer in the soil, and a compact texture can increase the trouble of dropping buds.
If you overuse fertilizer, it will make the soil oversaturated with nutrients and make it unhealthy for developing blossoms. On the other hand, using less fertilizer means there is not enough nutrition to promote bud formation.
Also, if the potting mix is not loamy, it will lead to waterlogging and root rot and eventually make the plant weaker, not enough to support blooms.
The best way to solve this is to use succulent soil. We have a great list of potting mix recipes here!
8. Excessive Number of Buds
This happens when this favorite holiday season plant forms more flower buds than it has the capability to support, especially during peak time.
To conserve energy, it may shed a few extra ones. The best way to help is not by deadheading these excessive buds, but by keeping growing conditions steady.
Avoid moving the plant suddenly to another location for a better flower show, watering inconsistently, and not maintaining good light and humid surroundings are also big red flags.
Apply these tips and your Christmas cactus will hold onto its buds and reward you with a dazzling bloom.
