Reasons for the Dropping of Tomato Blossom

Reasons for the Dropping of Tomato Blossom

There are few things in the garden that cause the gardener as much anxiety as the fall of their tomato flowers. One day the plants are blooming like crazy, and the next day the flowers are shriveled, lying on the ground next to your plant. You are wondering what you did wrong and how to prevent it from happening again. Rest assured, there are reasons why tomato flowers sometimes fall off plants and there are ways to avoid this. In this article, I will share 6 reasons for the fall of tomato flowers and offer practical solutions.

Should you be worried if you see tomato flowers falling?

Fewer tomato flowers means fewer fruits, so your first reaction to the fall of the flowers will of course be worry, disappointment and maybe panic. A few flowers that fall from time to time are natural (as you will learn below), but if you notice that a significant number of your tomato flowers are falling, you may need to take action.

As with everything that happens in the garden, there are things under our control (watering, fertilizing, etc.) and things that are not (humidity, temperature, etc.).). By discovering the 6 reasons why tomato flowers fall below, you will see that some of them are under your control, while others are not. Focus on the “why”, and if it is within your control to remedy the situation, your concern will disappear knowing that the problem can be solved. But if the “why” is out of your control, know that this is probably a temporary situation and that with the right measures you can still harvest a lot of tomatoes. Read on to find out more.

What to do if you see tomato flowers falling

Almost all tomato plants are exposed to some type of plant stress that can lead to short periods of flower fall. When you see tomato flowers falling from your plants, start looking for the possible cause(s). Only then can you take measures to solve the problem. Don’t panic. Instead, think logically about what could be the reason for this. Explore the possible causes below and be honest with yourself about how to take care of your tomato plants. Again, some of these causes are under your control and the solutions are simple.

6 Reasons why tomato flowers lose weight

There are a few factors that can be the cause of the fall of tomato flowers in your garden. Most of us are familiar with other common tomato issues, such as apical rot or fruit cracking that can make tomatoes inedible, and just like these two conditions, flower droplets come for a reason. Here are six possible causes of tomato flower loss.

1. Lack of pollination

Tomato flowers are perfect, which means that each flower has both the male part (stamens and anthers) and the female part (stigma and pistil). Each flower is self-fertile, which means that the flower can be fertilized with its own pollen (although sometimes cross-pollination occurs). However, the pollen does not automatically pass from the anther to the stigma of a flower; it must be “bumped” to be released. This release of pollen can occur during a windstorm, when the plant or flower is shaken, or due to the vibratory action of bumblebees or other pollinators.

Pollination by bumblebees is known as sonication, and it is the most effective way to pollinate a tomato flower and improve fruit set. The bee vibrates its flight muscles by feeding on the nectar of the flower. The resulting vibration shakes the pollen and fertilizes the flower.

A lack of pollinators can lead to the fall of tomato flowers. If a flower is not pollinated, it shrinks and the plant throws it away. This is also called an aborted flower.

If it is very hot, pollinators may not be active; if bee-damaging pesticides are used, there may not be enough healthy bees nearby; or if there are simply not enough pollinators nearby, usually aborted flowers can be spotted in the garden. Plant tons of bumblebee favorite flowering plants in and around your vegetable garden (sunflowers and echinacea are especially good candidates) to support as many pollinators as possible. Do Not Use Pesticides.

If necessary, you can use an electric toothbrush or an electric pollinator to pollinate your tomato flowers by hand. It is a tedious job, but effective, especially in tunnels and greenhouses where there may not be wind or pollinators present to loosen the pollen.

2. Large-fruited varieties

Some varieties of tomatoes produce very large fruits or produce abundant fruits. Plants with very high fruit production can cause flowers to fall (or reduce the production of future flowers). This allows the plant to shift its resources to the ripening of the fruit already on the plant.

Large-fruited tomatoes in particular are very sensitive to flower drops. That is why many of these varieties, such as ‘Dr.Wychee’s’ or ‘Cherokee Purple’, produce so little, but very large fruits. This is a kind of protective mechanism, because if too many large fruits are allowed to fully develop on the plant, the stems will break or the plant will not have enough resources to move.

3. Lack of resources

And speaking of resources, the fall of tomato flowers can also be caused by a lack of growth sources such as light, nutrition or water.

Light: Tomato plants need at least 8 hours of full sun a day. If the plants are too shaded, they may not be able to perform enough photosynthesis to promote the development of many fruits, causing some tomato flowers to fall off the plant.

Nutrition: if one of the macro and/or micronutrients is not found, the plant only has the resources available to support a limited number of fruits. As they grow, tomatoes need a constant supply of phosphorus, potassium, calcium, nitrogen, and other nutrients. On the other hand, too much nitrogen can lead to a lot of lush green foliage with limited flowers and fruits. Use a tomato-specific fertilizer combined with an annual addition of compost to ensure that your plants have enough nutrients in the right balance.

Water: The third source of concern is water. It is also very important to limit the loss of tomato flowers. The root systems of the tomato spread widely, but they do not necessarily have deep roots, which means that the plant has access to water only from the first 6-8 centimeters of soil. If the soil moisture is not sufficient or constant, the result may be the fall of tomato flowers, because the plant knows that it does not have the means to support the ripening of the resulting fruits.
Water your tomatoes deeply, directing the water directly to the ground and letting it soak. Do not let your plants dry completely between waterings (Hello, terminal rot!), and mulch them well. Here is a detailed article on how often to water tomatoes.
