Chilli is one of the most used spice crops in the world. There is no better way to provide the harsh and bitter taste in your food than using chilli. It is an absolute delight to use chilli to bring out the flavour of your food and make it worth it. Indian have always been very excited about their rich spices, and they never lagged behind in this. The Indian chillies are worldwide known and are amazing to taste.
Chilli is a part of the botanical family Solanaceae. The flowers seen on the plant are small, white ones, and they often are downward facing. Even the chilli fruit which grows on the plant is similarly growing downward, and hence they hang beautifully from the main plant.
But this transformation of the flower to the main fruit depends on a number of factors. The fruit bears seeds and without this, it is not possible to have the next growth. There can be a number of reasons why a situation of chilli plant flowering but not fruiting is seen. It is really hard to get close to perfection and then later losing the result of the fruit.
Flowers growing into fruit depends on a number of factors such as the intensity of the sunlight, humidity, water content, air, and many other such things. Chilli drop is a usual event, but a situation where chilli flowers dropping off is seen as very tragic.
Why does such a thing happen?
The gardeners very easily face this problem of chilli flower drop in their plants. It’s also a natural phenomenon as these shrubs do drop the flowers for giving a balance to the plant.
The main stem of chilli is so weak that due to excess flowering, it is seen that the plants do shed their flowers. It’s very normal for a healthy chilli plant, but there can be many other reasons for having this “blossom drop.”
Optimal temperature matters-
This factor really plays a lot for flowering and fruiting. The chilli plant is very limited in the temperature range. They are very sensitive to high temperature, and due to this factor, the gardeners face problems in maintaining the crop.
The morning temperature ranges from 20-10 degree celsius in the daytime. The plant drops the flower as an option to survive. This is a typical case of chillies flowering but no fruit. There can be other temperature-related facts, but you will have to see and analyze exactly which part of your plant gets damaged by the heat variation.
Fertilizers-
Another big point in chilli flower dropping off is the misuse of fertilizer. Many gardeners don’t get the entire concept of fertilizing, and hence they often think that using extra fertilizer is beneficial, but it is completely a myth. It can just backfire, and hence one needs to have a clear and keen analysis of the type of fertilizer, and the quality of fertilizer one should use. A better way would be consulting an expert for this—one who can analyze and work in detail.
Water Content-
Water plays a very unique role in plants. When you analyze the situation and see how it can work, you can observe the fact that both extreme water and low water can be harmful to the chilli plant. Both of them can cause chilli flowering but no fruit. When the water content gets lowered up in the soil and eventually in the plant, the chilli plant goes for an option to save the water from transpiration so that the water can be there for useful processes involving its life.
Flowers have their own water requirement, and also the surface area of the flower gives more surface for the water to escape; hence one can see chilli flowers dropping off. Similarly, in the case where water is in excess, the plant becomes heavy. Even the flower becomes loaded up with water, and the stem is full of water. In such a case, the flower can drop easily. The weight is a big factor in chilli plants, and hence they can’t make it easy if the plant gets full of water. It can even break the main stem.

Pollination-
It is a process in which the male spores from the male plant are transferred on the stigma of the female to form a zygote and later a seed. This process in chilly does happen via an agent. It can be air, water and many other such things. In the chilly plant, pollination is mainly via an insect.
Garden bees are a very common vector for this transfer. It is amazing to notice that lack of these vectors can cause the stoppage of pollination. Most of the gardeners aren’t aware of this fact. It will eventually lead in the death of the flowers.
The flower without being pollinated gets dried up, and hence the flower sheds off the plant. In such conditions, the flower needs to be pollinated by artificial means so as to make the flower stay on the plant. Even the gardener can do such a thing by using a cotton brush and artificial techniques.
Improper and incomplete pollination
Basically, even if anyone of the given conditions doesn’t match with a compatible pollination environment, then the process could be a complete failure. Any type of poor air circulation and improper agents can lead to such a situation. The life span of these flowers on the plant is very short, and even with a small change in the complete process, the pollination misses. This leads to Chilli Flowers Dropping Off the chilli plant after being dried up. The solution to such problems is easy, and a g can easily take some of these.
How to increase pollination?
It’s not very hard to increase the pollination rate in chilli plants. In chilli growing in gardens, the main pollinator is bees. This bee is one of the most amazing organisms in nature. To attract bees, you can plant many colorful flowers in the main garden or field where you are growing the main chilli.
Bees easily get attracted to the fragrance and sweet smell. Also, the big attractive looking flowers are very pleasing to the bees, and they like to come around these. This will accidentally help in the pollen transfer so moreover a great technique. But, you can never be sure of the success story. It is a complete case of hit and trial, and luck only can make the pollination better. If you are in an area with poor aeration or less attractiveness to pollination agents and if the pollination is the reason for Chilli flower dropping off, then you have nothing to do rather wait.
Nitrogen-
yes, don’t be surprised to know that the gas which is found the most in the atmosphere is one among the deficiencies responsible for chilli flowering but no fruit. The main reason behind this is the presence of nitrogen in free form in the soil in which the plant can use it. The nitrogen is very much important for the proper growth of chilli flowers.
Being one of the most essential macronutrients Nitrogen is very important for the blossom to remain perfect and later to transform into the chilli you want. Not only a deficiency but also an excess is very much harmful to the plant. In any case, if you took a chance to increase the nitrogen level much above the optimum, then the consequence could be a crop full of foliage bosom, and eventually, it costs in the toxicity of the land. There can be a shocking drop in the number of flowers in chilli plants, so be very strict in maintaining the appropriate amount of nitrogen for proper growth.
Air-
not only nitrogen but also air is a reason for such events. There can be many points on how air can affect the plants. The first case is itself the pollination rate. Chilli pollen is also travelled by air currents in the atmosphere which gives you an option of air pollination.
Unavailability of this airflow can reduce the pollination, dry up the flower, and then shed the flower. The second is the air content in the soil. Aeration is important for the roots. Due to tight soil, the air cannot get inside, and the roots don’t get the proper air. Further, this may lead to a lowering in the number of flowers. Even if the plant will grow, but the chilli plant flowering but not fruiting is seen.
Density-
The density or the area in which each plant is placed on the field is also a determining factor. If there are any plants on the field and the spacing is a problem, then the consumption of air and the circulation becomes weak. This may lead to chilli flowers dropping off. Sensity can be another factor by which the number of flowers can variate. The lesser the distance between pants, the lesser the growth is seen.
Humidity is very dangerous-
This plant likes to grow in dry areas. Proper and moderate humidity is required for easy and quick pollination. If the moisture content in air increases, the stickiness of the pollen also increases. The humidity is also a very important reason that can make the flowers heavy. This might be a very good cause for chillies flowering but no fruit. The content of the air is very determining, and hence small plants such as chillies do need the optimum condition. The blossom drop is very much significant in the areas with high moisture content.
Watering in the soil-
The water in the soil is important. If the water on the land where chilli is growing then it completely vanishes the fruiting in the plants. If the water level goes down the situation can be very stressful for the chilli plant. Due to such harsh conditions, the flowering might drop.
Water is very important for the overall growth, when overall is hampered the fruit is destroyed automatically. The chilli flowers dropping off can be seen in such situations, and water is something that can be really managed well. Even if the water is very much in the soil, it creates a lump. The aeration further decreases.
How to prevent this drop?
There are many factors for all these situations, and a gardener always wants a solution to it. So here are some of the things you can do to take of the problem-
- You cannot change the environment, and hence it’s not on your choice, but you can select the area where you are going to cultivate chilli. Even some solutions such as artificial heating and greenhouse gases are beneficial, and one can try using these artificial techniques for getting the plants back on track.
- Fertilization- it is very much sensitive in chilli plants. Most of them provide ammonia to the soil and hence are great with fixing nitrogen and providing other ions for the growth. Try providing a good amount of fertilizer just enough to support the flowerings.
Here is a key point with fertilizers.
Excess of fertilizers on your plant is very much more harmful than less content or no fertilizer. One has to be very specific with the amount.
- Try providing good water to the plant. Chilli is very sensitive to water. If they don’t get a good amount of water, the growth degrades a lot. Chilli flowering but no fruit is a very basic thing seen on the plant due to water.
- Sometimes there are many growth factors in the plants responsible for fruiting. One can easily get these chemically synthesized chemicals from the market and use these for use. Cytokines, Auxin and other chemicals are growth initiating hormones.
Conclusion
Dropping of flowers from the main plant is a very common phenomenon and sometimes it is even very natural. Chilli is so sensitive that even a tinge of variation in the conditions and your fruits are spoiled. The best a person can do is to make the situations favourable and more worthy for the plant.
