The plant is usually in full bloom when purchased, and it produces a steady stream of blooms for weeks or even months. Nurseries compel Kalanchoes to bloom in order to present their flowers to potential buyers. When does Kalanchoe flower in the wild? Kalanchoe can bloom virtually all year in its native habitat, but as a container houseplant, it blooms most frequently from late winter to late spring. As the amount of light available rises, this cycle will slow down.
To get a Kalanchoe to bloom again, you must first give it a rest and then mislead it into believing it’s a different season. Plants in higher light locations will require some closet time to replicate the lower light hours of winter hibernation, but plants in lower light regions will need some closet time to simulate the lower light hours of winter hibernation.
When conditions are favorable, a hibernation, or rest phase, is required for the plant to accumulate energy for flowering and growth. Keeping the plant in complete darkness for this time will cause it to awaken from its winter dormancy and produce flowers. Failure to provide a rest interval is one of the most common reasons for Kalanchoe not blooming again.
How many times does kalanchoe bloom?
On a small, upright plant approximately 6-12 inches tall, kalanchoe flower heads bloom in vibrant oranges, pinks, yellow, red, and white. The flowers last for months, while the green plants look good all year.
The most popular kalanchoe variety is K. blossfeldana, although there are many more to select from, including pendant (hanging) variations and nonflowering cultivars grown for their distinctive leaf. Growing conditions are the same for all kalanchoes.
Kalanchoe Growing Tips
Kalanchoes are low-maintenance plants that thrive in low-humidity environments like winter homes. Choose Kalanchoe plants with a lot of unopened flower buds instead of ones that are fully bloomed, and be sure to offer them:
Kalanches require a lot of light in the winter, particularly from a south-facing window, and intense indirect light (from an east/west window) in the summer. It’s likely that your Kalanchoe plant isn’t getting enough light if it’s lanky and thin.
Soil: Kalanchoe plants thrive in a well-draining cactus and succulent potting mix, or add plenty of perlite or sand to promote drainage.
Temperature: Kalanchoes perform well in average household temperatures, although drafts should be avoided. Keep your kalanchoe above 50 degrees Fahrenheit.
Overwatering is the most common cause of kalanchoe death! Between waterings, let your kalanchoe dry out. Then, after properly watering until it runs out the bottom, empty the drainage tray. It’s never a good idea to leave the plant submerged in water.
Fertilizer: Feed your kalanchoe with a balanced organic fertilizer every few weeks while it is blooming.
Pots: Kalanchoes grow best in clay pots with a drainage tray that can be emptied. They’re little plants that don’t need to be repotted too often.
Summer care: In the summer, you can bring your kalanchoe outside, but make sure it is protected from the rain.
Kalanchoes can be propagated easily from stem or leaf cuttings. Plantlets are produced by some kinds, which can be removed and potted.
To keep your kalanchoe looking tidy, remove any wasted blossoms. Dust can also be removed by wiping or lightly spraying them.
How to Make Kalanchoe Bloom
Many people treat kalanchoes as annuals, discarding them once they’ve bloomed. It takes some discipline to get them to bloom again, but once you get the hang of it, you’ll be able to make your kalanchoes bloom on demand! Here are some suggestions for re-blooming your kalanchoe:
Flowering is Light-Dependent: Kalanchoes are photoperiodic, meaning they bloom in reaction to the length of the day. They blossom in the early springtime. Six weeks of simulated winter illumination conditions are required to force your plant to set bloom buds.
Put your plant in complete darkness for 14 hours a day and brilliant light for 10 hours a day for six weeks to simulate night. To obtain complete darkness, you can bring it in and out of a closet or use a cover. When you observe blossom buds opening after six weeks or so, you can move your plant back into regular light conditions and continue watering. Check out our articles on how to grow poinsettias and Christmas cactus for more information on photoperiodic blooming.
How do I get my kalanchoe to bloom in the summer?
Maintain the plant’s temperature.
- Until midsummer, keep the kalanchoe in a warm room near a bright southerly window out of direct sunlight.
- During the growing season, water the kalanchoe thoroughly when the top inch of soil is dry.
How long does a kalanchoe bloom?
The kalanchoe blooms at the end of winter and the beginning of spring in its natural habitat. This occurs because it is a “short days” plant, which requires at least 13 hours of darkness per day to begin flowering. As the day lighting level rises, this cycle grows slower.
Kalanchoe will bloom poorly or not at all if the resting phase is not carefully observed.
How do you take care of kalanchoe in the summer?
Kalanchoes can be raised to rebloom the next season with proper care. After the plant has finished flowering, move it to a slightly larger pot. Kalanchoes are succulents that thrive in a well-drained, well-aerated potting soil made up of 60% peat moss and 40% perlite. Tall growth and old flower stems should be pruned. In a sunny, warm window, keep well hydrated. After the threat of frost has passed, relocate outside for the summer to a bright, lightly shaded location. Gradually acclimate them to outdoor conditions to avoid burning fragile foliage. Return to the house before the first frost or three months before the ideal bloom time.
Kalanchoes, like poinsettias, need short days (long nights) to form flower buds. Between October 1 and March 1, natural day lengths allow flower buds to form. Keep the plant in a room with no lights on during the naturally dark hours, or alter the length of the day by putting it in a closet in the late afternoons and then bringing it out to a high light environment each morning. Flower buds need about six weeks of normal winter day lengths to form. Kalanchoe will have a 14 to 16-hour night period due to natural winter day lengths. Temperatures exceeding 80 degrees Fahrenheit during the lengthy night period can cause a “heat delay,” preventing bloom development. Day length is no longer important after the flower buds grow large enough to be seen above the foliage. Plants can be placed in any position at this time, independent of night lighting. In early October, plants exposed to naturally short day durations should begin flowering by January (i.e. approximately 12 weeks from start of long nights).
Why are my kalanchoe not flowering?
Kalanchoe plants can flower for several months at a time, but they must shed their blooms at some point in order to rebloom. They will enter this dormant stage depending on the time of year and the length of the days. They usually lose their leaves at the end of the summer or the beginning of the fall season and begin growing new buds. The buds will bloom into beautiful blooms as the days grow longer in late winter and early spring. Don’t be concerned if your plant’s blossoms fade. It will bloom again in due time. Just make sure your plant gets adequate light in the spring so it can flower. A window facing south or west is great.
If a Kalanchoe plant has dead blooms on it, it may be spending its energy attempting to keep a section of the plant alive that is already dead. The plant will begin to spend its energy to generate new buds to replace the dead flowers if the dead blossoms are cut or pinched away.
Kalanchoe is a low-maintenance plant that should only be watered when the soil is completely dry. Allowing the plant to become too dry will cause it to wilt. Wilting can have a significant impact on future flower production. Also, take careful not to overwater the plant, as this might cause root rot. Check the soil on a frequent basis to check whether it needs to be hydrated! You can irrigate the soil if it is completely dry.
You may get the Kalanchoe to bloom at any time of year if you don’t want to wait for spring. Controlling the quantity of light the Kalanchoe receives will encourage it to blossom and bloom. Place the Kalanchoe in a dark closet for 12-14 hours every day, then return it to strong light for the last 10-12 hours. Buds will appear in 6-8 weeks if this procedure is successful.
Will kalanchoe bloom again?
It is feasible to re-flower a kalanchoe, but it will require some effort. Kalanchoes are’short day’ plants, which means that in order to develop buds, they require a’rest time’ of short days and long nights. That is why they begin to bloom organically around February. You can get around this natural propensity by allowing them only eight or nine hours of daylight every day for at least a month you can do this by putting it in a cupboard or a windowless room and only watering sparingly. After two months, you should notice fresh flower buds and can resume routine watering and feeding.
Is kalanchoe annual or perennial?
Kalanchoe blossfeldiana, also known as kalanchoe, is a succulent perennial with scalloped leaves and enormous umbels of flower clusters held above the foliage. It has a multi-branched, upright growth habit. For a houseplant, their bloom time is surprisingly long.
Why do kalanchoe leaves turn yellow?
Zinc insufficiency is a problem for Kalanchoe blossfeldiana, which is exacerbated by excessive phosphorus levels in the soil. Yellowing of leaves between veins, as well as curling, withering, and leaf deformation, are all signs of zinc deficiency. Zinc deficiency in Kalanchoe can result in fasciation, which is a highly branching, flattened stem. Kalanchoe requires a soil pH of 6.0 to 6.5 or a rich growing medium of equal parts peat and perlite to reduce the risk of zinc deficiency.
