When flowers fall off orchids? Flowers fall off Orchids when a fast shift in temperature or humidity happens. Low humidity, unexpected temperature changes, and dry air from air conditioners are the main causes of orchid blooms and buds falling off.
Indoor heating in the winter also contributes to this problem.
It should be noted that as part of their natural cycle, orchids naturally lose their blossoms after 6–10 weeks.
Why flowers fall off orchids
The most common causes of orchids falling off flowers or flower buds:
Orchid Flowers Fall Off Naturally After 6-10 Weeks
The most common houseplant orchids normally bloom just once a year (although they can blossom more frequently under ideal conditions), and as long as the conditions are right, the flowers typically last 6 to 10 weeks.
While moth orchids can bloom at any time of the year.
Fresh flower spikes usually develop during the colder Winter months, and the blooms are then shown throughout the Spring.
Orchids need a cold nighttime temperature in order for orchids to bloom in their native habitat in time to exhibit flowers for spring and summer.
Blossoms might fall off after 6 to 10 weeks because of the orchid’s response to the varying amounts of light and temperature with each season. This is a typical occurrence for orchids and is not always a symptom of stress.
You should prune the flower spike down to a height of half an inch above a developing node because orchids’ are not able to reproduce flowers on the same stem again.
If the stem (also known as a flower spike) becomes yellow and dried after the flowers have fallen off, cut the stalk down to the orchid’s base. Read my essay on the yellowing orchid stem.
Change in Temperature- Orchids Flowers and Buds Dropping
A sudden change in temperature that is outside of the orchid’s typical temperature range is one of the most frequent causes of orchid blooms and flower buds falling.
This often occurs when wintertime inside heating suddenly raises the temperature which kills the flowers.
Orchids can survive at temperatures between 66 to 86 degrees Fahrenheit which is ideal for most indoor settings.
Yet orchids usually adapt to particular environmental conditions.
Outside of the orchid’s typical temperature range, a quick temperature shift (hot or cold) can stress an orchid to the point that it drops all of its blooms or flower buds before they have opened.
The following factors are the most frequent causes of sudden temperature changes that harm orchids:
- climate control.
- sources of heat such as heaters forced air and fireplaces.
- temperature changes outside that can have an impact on orchids in conservatories or on window sills.
Orchids also require a colder temperature at night than during the day to mirror the natural temperature cycle in their natural habitat.
In most homes, the temperature rises at night (especially in the winter when interior heating is on) which is not what the orchid prefers.
Moth orchids (Phalaenopsis) enjoy a nighttime temperature range of 16–19°C (61–66°F).
So, it’s crucial to choose a location in the home that’s distant from draughts and direct heat sources.
Keep your orchid a little bit away from a chilly window sill because the blossoms can drop if the leaves or flowers come into touch with the window at night.
The orchid blossoms should remain on the plant for 6–8 weeks in stable conditions before dying.
Low Humidity Causes Orchid Flowers and Buds to Drop
Tropical plants native to Asia’s woods where humidity levels typically vary from 50% to 80% include orchids.
Household humidity is often substantially lower, at about 10%. The orchid loses water too rapidly and displays stress by dropping blooms because of the change in humidity.
While orchids are tropical plants, the common Phalaenopsis (‘Moth’) orchid has been developed such that it can survive somewhat lower levels of humidity than its native habitat, which is approximately 30%. Nonetheless, the orchid still needs more humidity than the air in most homes.
Homes’ relative humidity can vary rather wildly for a variety of causes, including:
- Draughts, forced air, air conditioning air currents, and conventional air currents brought on by heat sources.
- Much less humidity is present inside thanks to central heating or fireplaces.
- One of the first indicators of low humidity stress on an orchid is the loss of blooms, but low humidity also dehydrates the orchid’s leaves, aerial roots, and flowers, causing the leaves to droop or become brown. This is a sign of drought stress.
How to Fix It
By generating a humid microclimate that decreases drought stress and fosters favorable conditions for orchid blooms to last longer.
It is necessary to recreate the orchid’s preferred higher levels of humidity from its natural environment in the home in order to prevent orchid flowers from falling.
keep the orchid away from drafts, air currents, and heat sources because these conditions go against nature.
At your house, you can produce a humid microclimate in three ways:
- Every day, mist the orchid’s roots and flowering leaves.
- Put the orchid in a tray of water that has been filled with stones. This will keep the bottom of the orchid’s pot above the waterline, allowing moisture to drain after watering to avoid root rot.
- Employ a humidifier for indoor plants that enables you to precisely adjust the humidity level to the orchid’s optimum range.
I suggest misting the leaves or setting the orchid in a tray of water with stones for the majority of homes (the water evaporates around the orchid which increases the humidity).
But, a plant humidifier (available at garden shops and on Amazon) is the best choice if you live in a very dry region because it is extremely good at recreating the ideal conditions for orchids.
The orchid can keep its blossoms for a longer period of time if it is in a more ideally humid environment, and any budding flower buds can emerge without running a higher chance of falling off.
Drought Condition Causes Orchid Flower Buds to Drop
Low humidity and insufficient watering can cause orchids to last drought stress which causes them to lose their blooms and flower buds.
Low humidity dehydrates the leaves, roots, and flowers, and if the potting soil entirely dries out, the flowers and flower buds fall off.
While in bloom or while the flower buds are growing, orchids need at least 40% humidity and should be watered at least once a week.
When an orchid experiences drought stress, its leaves become yellow and look to be withering.
During a time of drought condition, the blooms disappear fairly rapidly because the orchid cannot support them and drops the blossoms to preserve its resources and maximize its chances of immediate survival.
Always give orchids a good soak to ensure that all of the potting material is uniformly saturated and that any surplus water drains through the drainage holes in the base.
As an alternative technique of watering, you can submerge the orchid’s pot in a basin of water for a short while. This will effectively ensure that the potting material is equally wet.
The top inch or two of the potting material only gets wet when the orchid is watered too little, and the water does not effectively reach the roots where it is needed.
This is supposing that the orchid is positioned in a pine bark-based potting media designed especially for orchids because this mimics the growth conditions of the plant’s natural habitat and has an aerated stricture.
Watering Too Often- Orchid Dropping Flowers
Overwatering can damage orchid roots because it prevents oxygen from getting to the potting soil which might hinder the orchid’s capacity to absorb moisture and nutrients.
As a result, the blooms and flower buds fall off and the roots begin to die.
To preserve resources and protect vital plant tissue, such as the surviving roots, leaves, and pseudo-bulbs, which often turn yellow in response to overwatering, orchids will lose their blooms and flower buds if their roots are dying.
Orchids normally need watering once every seven days throughout the spring and summer, and once every ten days during the winter.
The top inch or two of the orchids’ potting media should somewhat droop between watering sessions.
Overwatering is the probable reason for the orchid losing its blossoms if you water it more often than once per week.
In addition to watering, choosing the proper potting media is crucial to ensuring that your orchid has the ideal moisture balance.
The best potting soils for orchids are those based on pine because they mimic the well-draining, aerated conditions in that orchids naturally thrive.
Orchids are epiphytic plants meaning they grow in trees rather than the ground.
If they are put in potting soil it prevents oxygen from reaching the roots and holds too much water.
The orchid will rapidly die and the blooms will fall off.
Repot your orchid because when the moss or pine bark decomposes every two to three years.
It will retain too much moisture and less oxygen.
Repotting Shock- Orchids Flowers Falling off
Repotting orchids while their flower buds are still growing might result in the loss of the blooms or flower buds.
Repotting an orchid interferes with the root system’s capacity to suck up moisture and nutrients from the potting material.
After repotting, blooms will wither as an indication of stress if the roots cannot absorb moisture effectively.
Orchids should be replanted every two to three years because the potting media decomposes with time.
Retaining too much moisture and reducing the amount of oxygen surrounding the roots of the plant.
However, replanting shouldn’t be done when the plant is in bloom or while the flower buds are forming.
Although flowers and flower buds need a lot of energy and resources from the plant.
If the orchid is under any form of stress when it is producing its flower or the flower buds. It prioritizes survival and drops any flower buds.
When plants are repotted, their roots are frequently disrupted from their familiar potting mix and are unable to adequately absorb water which causes stress.
Repotting orchids in pine bark-based potting media is also recommended because they have the ideal structure to provide the right amount of moisture for orchid growth.
When an orchid is replanted into a moss-based potting media, the well-draining pine bark and the relatively greater moisture retention moss often cause the blooms to fall off and the roots to shrivel up.
The optimal time to repot orchids is in the spring or fall after they have bloomed, while it is feasible to do it at any time of the year.
Key points
- Usually, too high of a temperature or too low of a humidity level causes orchid blooms to wilt. Tropical plants called orchids demand high humidity and temperatures between 61 and 86 degrees Fahrenheit. If the temperature is too hot or the air is too dry from interior heating or air conditioning, orchids lose their blossoms.
- If there is a rapid shift in temperature and humidity, or if the orchid is underwatered or overwatered, the flower buds will fall off. When the potting material fully dries up in between waterings, orchids get stressed and lose their flower buds.
- In the event that the potting soil fully dries up, orchid blossoms fall off. The orchid strives to preserve moisture by dropping its blossoms if it is not watered often enough or too sparingly. While in bloom, water orchids every 7 days to keep the blossoms from falling off.
- If orchids are watered too often, their blossoms can fall off. The roots are unable to carry moisture and nutrients throughout the plant to sustain the display of flowers if the potting media is persistently wet, which prevents oxygen from reaching the area surrounding the roots and causes the flowers to fall off.
- If an orchid is replanted while it is in bloom, the blossoms will fall off. Repotting disrupts the existing root structure of the orchid and can momentarily impair its ability to absorb water adequately. Flowers should droop after repotting if the roots cannot absorb water to assist the orchids in efficiently saving their resources.
- Flowers on orchids usually last 6 to 10 weeks before falling off. This is a typical aspect of the orchid’s annual cycle and is not a sign that anything is amiss with the plant.
What Happens When an Orchid is Done Blooming?
Your orchid will bloom for a time and then go into its resting phase, much like many other flowering plants.
The blooms will start to droop, wilt, and finally fall off as the stem begins to turn yellow.
They will fade away at their own rate, just like the flowers did when they opened one by one.
Over the course of a week or two.
As the Phalaenopsis orchid plant reaches its resting stage after finishing its blooming cycle its flowers fall off.
It must focus all of its energy on the root system at this stage of its life cycle in order to keep it alive, healthy, and ready for the next cycle of flower production.
The plant stores energy in preparation for reblooming, or the production of new blooms during the orchid’s resting phase.
What to do when orchid flowers fall off
The greatest thing you can do for your orchid once all the blooms have fallen is to trim the tall ‘spike,’ relocate it to a cool location, and maintain its health.
How to Cut Back an Orchid After Blooming
Use clean and clear pruning shears (stainless steel is best) because you don’t want to give your plant any additional germs or unwanted objects.
First, after all of the blossoms have fallen look at your flower spike or stalk.
Just below the final blossom, if it is a great bright green color and somewhat solid, trim it back. This will be above the node, which is the highest joint.
Another cluster of blooms could appear here if the spike is healthy.
The plant doesn’t have to use a lot of energy to develop a new spike as long as the existing spike is healthy and remains that way. Thus, this could indicate a quicker rebloom.
It mostly depends on the kind of orchid. On an old spike, blooms have sometimes grown back more quickly for me.
Even though a spike initially seemed to be in terrific condition, it sometimes ends up withering away.
But, keep a watch on this spike; if it even hints at becoming brown.
You’ll need to trim it even further.
If you’re just starting out with orchid care, you may want to consider removing the spike at the plant’s base so it can concentrate on growing vegetatively. especially if it is in its first blooming cycle.
By eliminating the element of guesswork, the plant can concentrate on maintaining strong roots which form the framework of your plant.
You must clip down any yellow or brown spikes all the way to the plant’s root system.
The stem is in the process of withering when it reaches this color, and flowers won’t rebloom on it.
How to Care for Your Orchid in its Resting Period
It’s time to let the orchid enter its resting stage now that flowering is over and the stem has been pruned.
The plant will rejuvenate here, soaking in water and sunlight before ultimately putting itself back together to create gorgeous blossoms.
Finding the ideal quantity of sunshine is one of the key elements in orchid reblooming.
In this case, brilliant, diffused light is the ultimate aim.
It’s often not a good idea to place your orchids just in front of a window because the glare will nearly always burn the leaves.
But you can simply avoid this by covering your window with a protective film.
My bathroom has a west-facing window that is quite bright all the time, and I have numerous orchids there. We covered the glass with this opaque film, and my orchids have never been happier.
If you still want to be able to see out of your window, you can cover it with a UV protection film, which will prevent direct heat and give your orchids the same effect of diffused light while still enabling regular viewing of the outside world.
How to Make Orchids Rebloom
If given the right care and conditions, your Phalaenopsis orchid should bloom again in two to three months after the flowers have fallen off.
As the blooms fall off, there are numerous things you can do to encourage your orchid to rebloom.

As the blooms fall off, there are numerous things you can do to encourage your orchid to rebloom.
To induce dormancy, move your orchid to a cooler location.
Moving your orchid into a colder location, around 10 degrees lower than where it has been residing, is one of the greatest ways to get it to bloom again.
The natural signal that would typically be received in the wild indicating that the blooming season is over and it is time to start working on the next phase of flowers is mimicked by this.
Place your orchid next to a window if you live somewhere in a colder environment, as I do in Canada. The colder, draftier air entering through should be sufficient to activate this indicator when the outside temperature lowers.
Take your orchid outdoors and let it sleep on the porch for a few weeks if the temperature in your area doesn’t change significantly.
See how much water it needs.
Continue watering, but pay attention to the roots to see whether it still needs water or not; the timetable can not be ideal.
Give them some water if they’re starting to appear a touch lifeless.
Another approach is to raise the orchid and see whether it feels light and airy; if so, water is needed.
No additional water if it’s still heavy or the roots are almost turning yellow.
Here’s a suggestion to assist you to prevent overwatering: spritz the plant’s base once or twice a week. This is a simple method to maintain moisture without the risk of overwatering.
A little dampness is good for orchids.
Put your pot on top of a pebble-filled saucer. You can provide a little more humidity to the area surrounding your potted orchid by keeping water in the saucer’s bottom.
Fertilize
Instead, you can keep fertilizing your orchid every six weeks or once a month. And don’t worry if you forget to feed your pet.
When it comes to fertilizing orchids, little is more.
I advise using Better Gro instead of Miracle Grow fertilizers, which are manufactured in large quantities.
FAQ
Are orchids dead when the flower falls off
No, orchids are not dead when the flower falls off. Actually, the orchid’s life cycle requires that the blossoms finally wilt and drop off. The plant can continue to grow and develop new leaves as well as blossoms in the future with good care.
Do orchids grow back after the flower falls off
Yes, orchids do grow back after the flower falls off. The capacity of orchids to generate new blooms either on the same stem or a different stem entirely is well recognized. New flowers often take from weeks to months to bloom.
What month do orchids lose their flowers?
Orchids lose their flowers in late June and July.
How often do orchids shed their flowers?
Once a year orchids shed their flowers.
Conclusion
As you can see, maintaining orchids after blooming involves a little bit of a system, but if you get the hang of it, you should be blessed with orchid blooms at least a few times every year.
Good things can happen with a little awareness, tenderness, and love. You’ll want more and more and more after you manage to coax your orchid to bloom once again.
