I received a Kalanchoe as a gift plant this summer and I am now struggling to get it to bloom anew. Kalanchoe is an African native that has become a common house guest in North American homes. These plants require low light conditions to force budding. Ideally, the plant should experience 14 hours of lightless conditions to promote budding and bloom. Getting Kalanchoe to bloom again requires a bit of a rest period for the plant, correct lighting and some good fertilizer to fuel the process. A few tips on how to make a Kalanchoe rebloom will ensure success and a beautiful flowering houseplant in winter.
Kalanchoe Bloom Time
Usually, the plant is in full bloom at purchase and produces a constant parade of flowers for weeks or even months. Kalanchoes are forced to bloom by nurseries in order to present their flowers for purchasers. When does Kalanchoe bloom naturally? In its native region, Kalanchoe can bloom almost year around, but as a container houseplant, it is most commonly blooming in late winter to late spring. This cycle will slow down as lighting increases.
Getting a Kalanchoe to bloom again requires a rest period for the plant, and then tricking it into thinking it is a different time of year. Exposure to lower light levels during fall and winter will generally encourage the plant to bloom, but plants in higher light regions will need some closet time to mimic the lower light hours of a winter hibernation.
A hibernation, or rest period, is necessary for the plant to amass energy for blooming and growth when conditions are favorable. Keeping the plant in no light for this period will awaken the plant from its winter slumber and cause flower production. Failing to provide a rest period is often the reason getting Kalanchoe to bloom again may be unsuccessful.
How to Make a Kalanchoe Rebloom
After the flowers on your plant begin to fade and die, cut them back and remove the spent blooms. This prevents the plant from directing energy to trying to sustain a part that is already spent.
During the summer, keep the plant in well-drained soil in a sunny location and maintain a moderate moisture level.
When fall arrives, cut back on water and move the plant indoors if you are in a zone below USDA 9 or where frost is expected. The plant will experience low light conditions from fall to late winter, which normally causes flowers to form.
Fertilize with a 0-10-10 in late winter or just as the first buds are forming. This will promote better and more Kalanchoe flowering and enhance plant health and vigor.
Tricking a Kalanchoe into Blooming
If you want your plant to bloom at a specific time, such as Christmas, you will need to do some planning. Minimize watering and give the plant a 14-hour period without light daily 6 weeks before the desired bloom time. Place the plant in a closet or under a box for 14 hours and provide 10 hours of bright light.
Keep the plant warm and away from drafts. Do not water or feed the plant for 6 weeks, as it is dormant. As soon as you see flower buds, move the plant to brighter lighting and resume watering. Feed the plant in spring and remove spent flowers to encourage new buds.
These plants are easy to grow and provide up to 6 months of beautiful little flowers and thick attractively scalloped leaves.

Kalanchoe does not bloom and stretched
Having studied it is possible to learn the life cycle of cause and cause the appearance of inflorescences of the plant. Flowering is the end of the vegetative cycle, which in most plants is constantly repeated from year to year.
Additional information!We Kalanchoe appearance of new buds in the home takes place in the period from December to July.
There may be several reasons why this process has been broken, from which one can understand why not a decorative Kalanchoe blooms:
- unsuitable climatic conditions
- the wrong watering schedule
- improper placement on the windowsill
- lighting is poor
- unsuitable temperature conditions
- no fertilizing or over-saturation of soil nutrients
- no rest period.
House plant can withstand the heat and dryness in modern apartments. Height formed flowers and buds be suspended if the air becomes cool or drafts occur. In warmer months, it is recommended to maintain the room temperature not higher than +25 ° C.
NoteIf the ambient temperature is not changed, but not decorative Kalanchoe blooms – it may be a natural aging plants
Watering is carried out with water at room temperature once a week – usually on the heat. The flower does not tolerate frequent and abundant watering. The next watering is carried out when the soil dries 2 cm. In winter, reduce watering to 2 times a month.
How often flowering Kalanchoe? Another fact that should be considered florist: Kalanchoe pleased with its flowering only once a year. This culture blooms sporadically, even in the wild.
Tropical flowers always love sunlight. Kalanchoe is desirable to place on the sunny side, but avoid direct sunlight. Summer suitable for placing flower western and eastern side sills. With a large number of light leaves becoming saturated in color. With a deficit of light leaves turn pale and become thinner, the shoots are stretched, and then flowering and growth stops.
Among the common causes for which new buds do not appear – excessively rapid growth of succulents. Kalanchoe blooms and not drawn when the owner does not follow the height of a house plant and not to limit it. The optimal plant size should not exceed 25-35 cm stem can grow up to 40 cm when in the care of these mistakes have been made for him.:
- abandonment of crop shoots
- a large amount of fertilizer
- high ambient temperatures.
ImportantWhen the plant is limited in growth, but does not plan to bloom and the leaves appear whitish stains or cracks – it means exhausted the earth in a pot
How to make Kalanchoe flower at home
Prepare the culture of the new season of flowering as soon as the plant ottsvetot. After the flowers on the plant withered and dried up, they are cut.
Otherwise, the plant will not be able to properly prepare for the next season of flowering. At the same time cut off unnecessary shoots, to give the desired shape flower. Such pruning is carried out continuously, with the growth of new shoots. This will form a lush, beautiful bush.
Succulents in heat form the high bush flower needs to be translated in a cool place. Overfeeding prevents the formation of flower buds because fertilizer stimulates the growth of leaf mass.
Stress makes it possible to stimulate the release of stems, but only if it does not last long and controlled. The sequence of operations will be as follows.
- Gain watering frequency. The soil under the succulent must be constantly moist for 2-3 days.
- Double portion of fertilizers. The plant will rise “sleeping” kidneys.
- Loosening the soil at the roots.
Aeration of the root system provides the roots of the plant air.
How to crop flowering kalanchoe for?
Pruning is recommended for all types of ornamental plants as a measure to stimulate flowering. Since the development of the stem with the top runners have a tendency to stretch and become infertile.
It is important to know how to pinch Kalanchoe her to blossom. Two processes (topping and pruning) are similar to each other, so they can be combined into one:
First you need to choose the weakest apexes, which for a long time were not strewn with flowers. A small portion of the stalk removed with scissors or your fingers to the wound was small.
The edges of the stems to avoid the death of a flower after topping treated ash or activated carbon.
The process of removing wilted stems and leaves to prevent the development of diseases and the plant will give a neat appearance.
Tips for care bloom
To flower buds appeared on the houseplant care regimen should be reconsidered.
Permanent stay on the window sill on the sunny side of the house, forcing the plant to grow in height, spending on this process all the juices.
It is necessary to refuse from excessive watering. The leaves can accumulate moisture and spend it gradually, so the lack of water is not as damaging as the surplus. In the summer watering process should be carried out once a week, twice a month in the winter.
Fertilize the plant ready fertilizer for succulents. If it does not bloom, it could mean that he wanted mineral complex with potassium, sodium and manganese in the composition.
Kalanchoe is easy to grow, and with that can handle even the children who are interested in flowers.

Getting Florist Kalanchoe to re-bloom
Once you have mastered these kalanchoe blossfeldiana care tips, you’ll want to know how to get it to flower again next year. This can be a problem since it loves cool, short days.
For this reason, Kalanchoe blossfeldiana is often cared for as an annual. Many people just allow it to have its months of bloom time and discard it.
The plant is cold hardy only in zones 10 and 11, so it can’t be planted outdoors after the flowers have faded and expect it to over winter, so what is one to do with it?
Getting this pretty succulent to re-bloom is possible but does require some skill. Read on for tips to extend your bloom time.
Kalanchoes, like Poinsettias and a few other holiday plants, are photoperiodic. This means that they react to low light days by setting buds. In nature, kalanchoes will flower in early spring. This happens after a period of low light shorter days.
To get your plant to re-bloom next year, you will need to simulate natural winter light conditions in your home for a period of six weeks. This can be a challenge because of artificial lighting indoors.
Start by cutting down on your watering schedule. Water only half as often as normal (or even less than this.)
During this period of 6 weeks, put your plant into complete darkness for 14 hours a day and then bring it back to bright light for 10 hours a day. This might seem impossible for most homes, but it really only means using a closet or other dark room for the 14 hours to achieve the darkness.
Another way to achieve the darkness requirement is to have a box handy that is large enough to slip over the top of the plant. Just pop it over each night for 14 hours and remove the next day.
If you do this for a period of 6 weeks, you will encourage new flower buds to form. At this time, bring your plant back into normal light conditions and begin watering again.
Be careful of temperatures during this period. If they go too low, this can prevent buds from forming.
This is exactly the same process that you use to get a poinsettia or Christmas cactus to bloom again each year. It requires some discipline and a tight schedule but is worth it to get the pretty flowers that you know will last for another few months to come.
If you do this process about 6 weeks before the holidays, you’l have a beautifully flowering plant at Christmas time next year that will keep its cheery color all through the following winter months!
How to Get a Kalanchoe to Bloom
Kalanchoes are flowering succulents that come in a variety of colors of blooms such as yellow, pink, red, orange and lilac. Pronounced ka-lan-ko-ee, they are perennial and evergreen with an average blooming period of 40 to 65 days. Kalanchoes are succulent plants suitable for dry landscapes or container gardens and ideal as indoor plants. Getting kalanchoes to bloom again after the first blooms dry out can be a challenge however, it is doable depending on certain environmental conditions.
Purchase kalanchoes in pots during the bud stage to give you longer blooming period.
Put kalanchoes under full sun. They do well in a situation with lots of light. If grown for very long without enough light, they become weak. Put the pots outside during the summer, but bring them inside before the first sign of frost. When growing indoors, place the pots in front of an east- or west-facing window or put the plants under artificial plant lights for 13 hours a day.

- Purchase kalanchoes in pots during the bud stage to give you longer blooming period.
Water thoroughly and then allow to them partially dry out before watering again. Make sure to use a container with drainage holes to ensure the water drains completely. Be very careful not to let water accumulate or the plants will rot.
Keep the kalanchoes in room or warm temperature. They do well in temperatures between 60 and 70 degrees F, but are able to tolerate as low as 50 degrees F. Leaving them outdoors at 100 degrees F temperature will cause their leaves to develop brown spots.
Maintain indoor average humidity of 35 percent. Since kalanchoes are succulents, they do not require the high humidity that most indoor plants require.
- Water thoroughly and then allow to them partially dry out before watering again.
- Make sure to use a container with drainage holes to ensure the water drains completely.
Apply fertilizer only if you are planning to re-bloom later. You do not need to apply fertilizers when purchased in bloom. Fertilize after the rest period with a water-soluble fertilizer.
Remove dry or dead leaves and flowers right away. Pinch them off with your fingers or use garden shears to cut them off.
Give the kalanchoes a cool, shady, dry rest period of at least a month after all the blooms have died and then re-pot them. Choose cache pots twice the size of the plant. Use fast-draining soil when planting kalanchoes. Soil used for growing cacti known as cactus soil is ideal for growing kalanchoes. Buy ready-mix cactus soil from home improvement or garden centers. Make your own cactus soil if you cannot find the ready-mix ones by mixing one part potting soil with one part sand and adding a little gravel to the mixture to aid in the drainage.
- Apply fertilizer only if you are planning to re-bloom later.
- Use fast-draining soil when planting kalanchoes.
Force the flowers to re-bloom by giving the kalanchoes a longer night than day. Cover the pot with a cardboard during the day to accomplish this. The buds will start to appear and blooming takes place when the days become short enough (or the nights long enough). A typical long night period is 14 hours per day.
Put them back in front of the windowsill to get full sun as soon as you see flower buds appear.
Use a dark cloth on stakes in lieu of a cardboard to give a longer night period for re-blooming.

Q uestion: My 8-year-old neighbor gave me a flowering kalanchoe plant for my 90th birthday last September. It's in a 3 1 / 2 -inch plastic pot with cactus soil that's hard as a rock. I water it when it's completely dry by soaking it until the water drains out the bottom. It's growing, but it doesn't look too well and has long since stopped flowering. I have a bag of regular cactus potting soil I can transplant it with. What size pot do I need? Is a clay pot better than plastic?
Answer: Kalanchoe are wonderful flowering plants that are often found at florist shops year-round. Caring for these tough plants isn't difficult, but it does require a bit of finesse, especially if you want the plant to bloom again.
Though kalanchoes have thick, succulent leaves, they are not cacti, and actually tend to do better in standard potting mix, rather than a cactus-specific potting soil. I suggest repotting your kalanchoe into a 6-inch pot using regular, high-quality potting soil, not the cactus mix you have on-hand. A clay pot would be fine, but it isn't necessary. Standard plastic or even a decorative glazed ceramic pot would work, though no matter what type of container you choose, make sure there's a drainage hole in the bottom.
If you plan to put your potted kalanchoe outdoors for the summer, however, I would not recommend using a clay pot as they dry out far too quickly.
Kalanchoe plants should be watered every 10-14 days. Don't let it become dry to the point of wilting as that can cause major stress to the plant and affect future flower production.
Fertilize your plant using a liquid organic houseplant fertilizer once per month from March through August. Never fertilize houseplants during the winter months when they aren't actively growing.
The trickiest part about growing kalanchoes is encouraging them to bloom again. Like poinsettias, kalanchoes are photoperiodic, meaning their flower production is dependant on the day length. Kalanchoe are short-day plants that produce flower buds when the day length shortens in the autumn and winter. The kalanchoes you see in bloom at the flower shop at other times of the year are forced to bloom at a particular time by artificially subjecting the plants to shorter “day lengths” via a precisely controlled lighting system.
In order to ensure your kalanchoe blooms again this coming winter, as soon as August arrives, keep the plant in a room that only receives natural light. This means, you can't even turn a lamp on in the room or have a porch light on outside the window at night. Many varieties of kalanchoe will come into flower naturally as the day lengths shorten in the autumn, as long as they don't receive any light at all after the sun goes down.
If this isn't possible, you can put the plant in a dark closet for 12-14 hours per day for two to three weeks. You'll know the treatment was successful if flower buds appear about 6-8 weeks later.
Though kalanchoes aren't quite as sensitive as poinsettias when it comes to day length and flower production, ensuring more blooms is definitely an art of perseverance and consistently. Missing even a single day of darkness is often enough to keep the plant from producing blooms.
