Why Are My Tomato Flowers Falling Off?

My tomato plant grew to be over 5 feet tall and produced many flowers, not a single flower turned into any variety of tomato. I was very disappointed because these are the only vegetables I like to eat fresh. 

They are not lacking in water as I have made sure that they are always looked after. I also gave them Miracle-Gro tomato fertilizer and bought a special soil to plant when I received them. As I said, I look forward to it every year. Find out why I never got tomatoes. Once the flower has fallen and the tomato begins to grow, nothing will come out.

Causes of tomato flowers falling off

Flower drop is a common problem when growing tomatoes that can be extremely frustrating for the home gardener. Healthy-looking tomato plants produce flowers. However, they merely wither and fall off the plant before a fruit forms. There can be many causes for flower drop, but the most common are temperatures that are too high or too low.

#1.High or Low-temperature ranges

The high temperature in summer is a common cause of the fall of tomato flowers. When the daytime temperature exceeds 85 degrees Fahrenheit for several days, tomato flowers will usually fall off the vine without fruiting. On the cool spring and autumn nights are temperatures below 55 degrees Fahrenheit can also cause the flowers to fall off.

 Low temperature can interfere with the normal development of tomato flowers and may lead to the formation of sterile pollen. High temperatures can cause defects in tomato pollen, which prevents fertilization and eventually forms unfertilized flowers. Dry and fall from the vine. The sudden temperature change from high temperature during the day to low temperature at night can also cause tomato flowers to fall off. 

#2.Shortage of water

Due to the lack of water or under watering to the tomato plant can be the cause of your tomato flower falling off is the most common reason and simply fix it with properly watering your tomato plants at least about 3 inches of water for a week provide with natural rainfall or with the manual concept.

#3.High winds

You can’t control the wind, but plant your tomatoes in reasonably sheltered areas. 

#4.Foliar diseases

Plants infected with foliar diseases can cause the tomato flower to fall. Some of these diseases include severe bacterial stains, botrytis fungus, and dot pressure.

#5.Improper pollination

If several plants aren’t properly pollinated, they’re going not to be able to bear fruit or produce new seeds to grow new plants. On a small scale, a lack of pollination can lead to an unsuccessful tree. In general, this can mean food shortages.

#6.High or Low humidity

Extremely dry or humid air will affect the fertilization of tomato blossoms. Tomato flowers exposed to dry or humid air with a relative humidity lower than 40% or higher than 70% may not be fertilized properly. Dry air causes pollen to stick to the stigmas of flowers, while moist air causes pollen to accumulate. Pollen cannot properly fertilize the flower, causing it to dry out and fall off the plant. 


Insects can cause tension to a tomato plant inflicting flowers drop. However, you have to keep away from the use of insecticides that can harm pollinators along with bees which might be essential in your vegetable garden.

#8. Heavy fruits set with too many blossoms

A tomato plant may have too many flowers competing for resources, causing the plant to drop several flowers, but once the first tomato is harvested, this problem should go away.

#9.Over pruning of tomatoes

If you remove those inevitable suckers from tomatoes that emerge from the branch unions. 

When you let them grow, they will become branches and stick to the plants, blocking light and flow of air. These branches will produce fruits, but the results may be too good. 

All these extra tomatoes are competing for the limited available nutrients, resulting in smaller fruits and lower quality. You need to remove the sucker by squeezing it with your fingers on the day of planting the tomatoes. 

If not, it may be best to abandon those that have become branches; but continue to remove new suckers, because they seem to limit future branch growth.

#10.Lack of nutrients

Poor soil can face a lack of nutrients due to this poor growing condition. Roots cannot get a sufficient amount of nutrients. So, the roots can be injuries because of mechanical, insects, and disease.

Make sure that test your garden soil and if you get a lack of nitrogen use tomato fertilizer which is balanced the nutrients deficiency and you can also add compost to your soil for better results.


Too much nitrogen on tomato plants can cause flowers to fall off. Nitrogen application to tomato plants can promote the rapid growth of their stems and leaves. Tomato plants that are over-fertilized with nitrogen gas typically have slender stems that can’t support the burden of the tomato.

When planting plants, it is best to use fertilizers with high phosphorus content but moderate nitrogen content, and then avoid re-applying fertilizer before the fruit is set. 

#12.Inadequate irrigation

Tomato plants have a branched root system that is sensitive to dry growing conditions. If the soil around the tomatoes dries out, the flowers will dry out and fall off the vines before they bear fruit. Evenly moistened soil a few meters deep around the plant promotes a healthy root system and ensures that your plant gets the moisture needed for successful results.

Why does my tomato plant have flowers but no fruit?

It’s one of the defeats when you have tomato flowers but not fruits or only tomato plants but no flowers at all. Earlier, you could be produced tomatoes with a little extra from the normal harvest.

#1.Blossom drop

Air temperatures will play an essential role in the production of tomatoes which are sensitive to low temperatures and extremely high temperatures. In early spring fall flower, drops can occur due to slightly warm daylight and temperature will fall below 55 degrees Fahrenheit at the night as well as the same phenomenon will occur in summer also.

Here we use a shade cloth to block the direct sunlight that falls on the tomato plant at high temperatures.

For cold temperatures use red plastic mulch sheeting or organic mulch enough to promote fruiting.

#2.High humidity

Tomatoes multiply when pollen falls from the stamens and pollinates the stigma. Usually, this pollination occurs due to the wind, movement, and vibration of the bee’s wings. 

High humidity can interfere with this process by making the pollen too wet and unable to move freely in the desired location. 

If you live in high humidity climates, you can help pollinate tomato plants by lightly touching flowers or flower stems. Another option is to gently brush the pollen from flower to flower with a small brush.

#3.Poor air circulation

As I mentioned earlier, flowers self-pollinate and immobilize pollen grains through movement. If the airflow around the tomato is obstructed, the pollen will not be able to fall and pollinate the stigma. To improve air circulation, try some of these options. 

Remove some of the foliage.

Don’t plant tomatoes too close together.

Trim the tomatoes.

Plant tomatoes vertically to improve air circulation and don’t plant behind the building or structure.

Instead, plant tomatoes outdoors on all sides.

#4.Too many flowers

Too many flowers on tomato plants will cause competition between flowers for nutrients because as a conservation method, tomato plants will automatically wilt and fall flowers

 After your plants set fruit, this problem needs to be solved without long intervention for good soil.

#1. Use natural pesticides

Use natural pesticides which are environmentally friendly and it will pick out the affected buds from the plant before spreading the problem.

#2. Keep soil evenly moist

Be sure about the soil should be kept moist and not be retaining a huge amount of water and getting soggy, it shouldn’t dry as well. So, mulch can help to regulate the mulching process.

#3. Check soil pH level

Check the soil pH value and maintain it as per the requirement of the seed. If you feel a lack of nutrients in your soil then add a layer of compost to fulfill it. 

#4.Monitor temperature fluctuations

First of all, monitor the temperatures and maintain between 12 to 29 degrees Celsius. If you build wooden or plastic containers which can control the shade for your plant.

  • The right temperature
  • Water properly
  • Use fertilizers
