Why Are My Tomatoes Falling Off The Vine?

As a farmer, the last thing you want to see is your plant dropping its fruit before harvest.

Whether you farm tomatoes, oranges, mangoes, apples, or even hot peppers, this is a painful experience.

Tomato growers are passionate about their fruits.

They put in a lot of funds, energy, and time to ensure that their tomatoes blossom and ripen.

Regrettably, not all tomatoes are harvested as some fall off the vine before they even ripen.

Why Are My Tomatoes Falling Off The Vine

Are your tomatoes falling off the vine before ripening and harvest? Worry not as you’re not alone.

We’ve faced a similar situation before.

For this reason, we embarked on helping other tomato farmers not to face the same situation again.

We did thorough research and even talked to a Pomologist.

Without wasting more time, here are some of the causes of tomatoes falling off the vine and what you should do?

Extreme Temperatures

If you grow your tomatoes in extreme temperatures, you may see the tomatoes falling before their rightful time.

Excessive high and excessive low temperatures hamper the smooth growth of your plant.

High temperatures of more than 90 degrees F during the day put a lot of pressure on your plant.

If the high temperatures continue like that for several days, then the fruit may fall off.

Besides, extremely low temperatures can also make the fruit to drop before it ripens.

Cold nights with temperatures below 55 degrees F will make the tomato to drop if it persists for several days.

Also, extremely high temperatures during the day and extreme cold temperatures at night will put a lot of stress on the plant.

What Should I Do?

Find out the best time to plant tomatoes in the area that you live. Also, plant the right type of tomatoes in your area.

Tomatoes that blossom in hot temperatures may fail to flourish cold temperatures and vice-versa.

What’s more, you can grow your tomatoes in a greenhouse or grow room so that they are not affected by adverse temperatures.

Lack Of Essential Nutrients

A common problem that makes tomatoes drop their fruits is the lack of certain nutrients.

The primary nutrients tomatoes need for healthy growth are nitrogen, potassium, and phosphorus.

Nitrogen is needed for growth and making of food, while phosphorus helps them to grow and handle stressful conditions.

So, if your tomato lacks any of these nutrients, it may result to slow or stunted growth.

In some cases, leaves may dry, and fruits may fall.

If your fruits drop and you notice yellow leaves, this is a sign of deficiency in chlorophyll.

Additionally, if the bottom of the leaves changes to yellow first, then it is an indication that your plant needs magnesium.

What Should I Do?

Knowing which nutrient your plant needs is vital if you’re to salvage other fruits on the vine.

If its magnesium, you can add Epsom salt to the plant.

Make sure you do not overfeed them as you will cause more problems.

Excess Nitrogen Fertilizer

Another common reason that can make your plant to drop its fruit is feeding it with excess nitrogen.

Even though tomatoes need nitrogen for growth, feeding it with excess fertilizer brings more harm than good.

The tomato plant will be lush and green with a lot of leaves, but the vines will drop the fruit.

This is because the stems will be thin and elongated and will not support the fruits.

What Should I Do?

Always feed the recommended amounts of every fertilizer, regardless of whether it is nitrogen, magnesium, iron, potassium, or phosphorous.

Over/under Watering Your Plant

Yes, your tomatoes need water to grow.

But did you know that overwatering your tomatoes may cause the roots to rot? Now you know.

On the contrary, you should not underwater your plant as it will also suffocate and die.

What Should I Do?

Provide your plant with the right amount of water weekly. The soil should not be waterlogged or too dry.

Water the tomatoes in the morning so that the water gets to the roots before evaporating.

Also, avoid watering on top of the plant, but instead water low close to the soil.

Overproduction Of Fruits

Many tomato farmers would be happy seeing one plant produce a lot of fruits.

But do you know that this puts a lot of pressure on the plant? As a result, some plants may not handle all of the blossoms, and that’s why they drop them as they grow.

The tomato plant only remains with the fruits it can support until the time of harvest.

What Should I Do?

There is nothing you can do about this as the plant is trying to protect itself. Just ensure that all conditions are right for the plant to flourish.

Insufficient Light

For your tomato plant to grow steadily and produce better yields, it needs at least 6 hours of direct sunlight every day.

This is quite challenging for some areas as they receive sunlight for a few hours.

The problem is worse in winter. Sunlight is essential to tomatoes as they convert it to energy to make their fruit.

So, if they don’t get sunlight, the fruit won’t develop properly, which might end up falling.

How To Fix It

Plant your tomatoes in an area where they will receive direct sunlight.

If you live in areas that receive less sunlight, then you should acquire a grow tent or greenhouse.


If you want to prevent your tomatoes from falling off the vine, then you need to take extra care.

No farmer is perfect as a small mistake, such as adding excess nitrogen can cause your tomato fruit to drop.

Now that you know some of the possible causes of your tomatoes falling, you should be able to detect what’s affecting your tomatoes.

Note that the conditions vary from one region to another.

When fixing the problems in your garden, don’t expect instant results as it is a process.

However, you should start seeing a change after a few days.
