Orchids are known for having some of the most beautiful flowers. But sometimes those flowers can start falling off the plant prematurely.
If your orchid is losing its flowers then you’re probably worried or upset. And wondering why your orchid flowers are falling off.
Well there are a number of factors to consider. In this article we’ll take a look at some of the most common reasons why orchid flowers may drop off and what you can do to prevent it from happening.
Natural Causes of Orchid Flower Drop
It’s important to note that in some cases it’s perfectly normal for orchid flowers to drop off naturally. This is especially true for Phalaenopsis orchids. They’re known for their long lasting blooms that can last for several months. But eventually the flowers will begin to wilt and drop off, making way for new growth.
In other cases orchids may naturally shed flowers as part of their natural growth cycle. This is particularly true for Dendrobium and Cattleya orchids, which have a more seasonal blooming pattern.
So make sure it’s not happening because of totally natural causes. If you’ve ruled that out then keep reading for more reasons.
Environmental Factors
One of the most common reasons why orchid flowers may fall off prematurely is due to environmental factors. Orchids are sensitive to changes in temperature, humidity and light, and any changes to their growing conditions can cause stress and lead to flower drop. Here are a few factors to consider:
Temperature
Orchids prefer warm, humid conditions and can be sensitive to drastic changes in temperature. If the temperature drops suddenly or they’re exposed to cold drafts then you may find the flowers dropping off prematurely.
Try warming them up by putting them somewhere warmer, away from anywhere there are drafts.
Humidity
Orchids thrive in humid environments. Low humidity levels can cause stress and lead to flower drop. Make sure your orchid is in a location with adequate humidity levels. If not then consider using a humidifier.
Light
Orchids require bright, indirect light to thrive. If the plant is not receiving enough light it could lead to it dropping its flowers prematurely.
Annoyingly orchids are very sensitive about light both ways though. So if it is receiving too much direct sunlight the flowers may become sunburned and drop off too.
Getting the light levels just right is one of the most important things you can do to keep an orchid happy. And a happy orchid will be much less likely to lose it’s leaves.
Watering and Fertilization
Another common cause of premature flower drop in orchids is watering and fertilizing them wrong.
Keep the following in mind to keep your prchids thriving:
Watering
Overwatering or underwatering can both lead to stress and cause flowers to drop off prematurely. Make sure you are watering your orchid properly. That means allowing the soil to dry out slightly between waterings and not overdoing it.

Fertilization
Orchids can do well without fertilizing. But doing so regularly will help them to thrive even more so.
Much like watering though too much or too little fertilizer can cause problems. So don’t go mad with it. Start slower and sparingly.
And make sure you are using the right type of fertilizer and applying it correctly. Using the wrong type will only stress and upset your orchid and make it more likely to die.
Pests and Diseases
Lastly, orchids can be susceptible to pests and diseases that can cause flower drop.
These are the most common issues to watch out for:
Pests
Mealybugs, spider mites and thrips are all common pests that can infest orchids and lead to flower drop. Keep an eye out for signs of infestation, such as webbing, white cottony masses or tiny bugs on the plant.
Diseases
Orchids can be susceptible to a number of diseases. The likes of root rot, bacterial or fungal infections or even viral diseases are common.
These can all cause stress and lead to flower drop. Make sure you are keeping your orchid clean and avoiding overwatering. If you water an orchid too much it can lead to fungal growth.
How to Prevent Flower Drop in Orchids
Preventing flower drop in orchids starts with understanding the needs of your specific plant and providing it with the right growing conditions. Here are a few tips to keep in mind:
- Keep your orchid in a warm, humid environment with bright, indirect light.
- Water your orchid properly, allowing the soil to dry out slightly between waterings.
- Make sure you are using the right type of fertilizer and applying it correctly.
- Keep an eye out for signs of pests or diseases and address any issues promptly.
- Avoid overhandling or moving your orchid too much, as this can cause stress and lead to flower drop.
It’s also important to note that some orchid varieties are simply more prone to flower drop than others. For example, Miltoniopsis orchids are known for their delicate blooms that can be easily damaged or drop off due to stress. If you are growing a more delicate orchid variety, it may require extra care and attention to prevent flower drop.
What to Do If Your Orchid’s Flowers Are Falling Off
If your orchid’s flowers are falling off prematurely there are some things you can do to help the plant recover.
- Address any environmental issues such as temperature or humidity fluctuations, and adjust your growing conditions as needed.
- Check your watering and fertilization practices and make sure you are providing your orchid with the right nutrients.
- Inspect your orchid for signs of pests or diseases and treat any issues promptly.
- Avoid overhandling or moving your orchid too much, as this can cause stress and lead to further flower drop.
It’s also important to remember that orchids are resilient plants and can recover from flower drop with the right care and attention. In many cases the plant will produce new blooms in the next growing season.
Final Thoughts
There are a number of reasons why orchid flowers may fall off prematurely, including environmental factors, incorrect watering or fertilization, and pests or diseases. By understanding the needs of your specific orchid and providing it with the right growing conditions you can help prevent flower drop and keep your plant healthy and thriving.
