What To Do If Tomato Leaves Are Turning Yellow? My Efficient Cures.


I planted a few tomato plants in the spring in my garden.

But all of a sudden the leaves turned yellow and all withered.

Why are my vegetable plants turning yellow in the vegetable garden? What is the problem ?

It was my gardener grandfather who answered this question.

He explained all the causes to me and above all gave me the natural solutions to find tomatoes in great shape.

Here are the reasons why your tomatoes have yellowing leaves and especially how to fix it. Look :

Growing tomatoes isn’t always as easy as people say.

But one thing is certain, a tomato plant in shape must have very green and firm leaves.

It stands upright with branches that don’t fall down.

But, as soon as the leaves change color, it is one of the first signs of disease or poor living conditions.

As soon as you see a change in the color of the leaves, you must act quickly.

Here’s how:

1. Why are my tomato plants turning yellow?

A tomato plant with yellow leaves can mean different things:

Improper watering suffocates the roots

The tomato hates having its roots soaked in water. As soon as the earth is too wet, it forms a compact clod which suffocates the roots.

Consequences: the leaves of the plant turn yellow.

And it goes very quickly.

In just a few days, the whole foot can turn yellow.

Obviously, in this case, all you have to do is stop watering and aerate the soil with a small hoe.

A long drought

A lack of water also causes the leaves to turn yellow.

But this time, they dry up and shrink from the base of the plant upwards.

Yellow spoon leaves are a sign that should not be ignored.

In this case, it is enough just to water the plant a little.

But be careful not to drown it!

Exposure to hot sun

Yes, tomato plants need sun…but blazing sun doesn’t suit all varieties.

The sun can « burn » the leaves. They then become yellow, dry and brittle.

In this case, protect the leaves during the hottest hours of the day.

Too rainy weather

Tomato leaves hate getting wet.

When the summer is rainy, the leaves are constantly wet.

They eventually turn yellow. They may also have small brown spots on the top.

Another concern: the association humidity + heat is synonymous with fungal diseases for sure.

A weather problem against which nothing can be done.

On the other hand, tomato plants can be housed in a small greenhouse.

It’s even easier if they are potted, just move it under cover.

A soil that is too poor causes deficiencies that cause the leaves to turn yellow

If the soil is not rich enough, the vegetables will lack nutrients and trace elements.

Consequence: they do not develop well and have deficiencies.

Worse ! They’ll catch any diseases or parasites that pass by.

In this case, add a little fertilizer to your tomatoes to enrich the soil.

And don’t forget to « boost » the soil next spring before transplanting the vegetable plants.

The end of the season

With the onset of the first cold nights, the tomatoes suffer.

All the leaves begin to turn yellow, both young and old.

Sudden temperature changes damage fruit and foliage.

Unfortunately, there is not much to do. The arrival of autumn signals the end of good fresh tomatoes.

Don’t forget to harvest before it’s too late.

2. Why are my tomato plants wilting?

withered tomato leaves why and natural remedies

Tomato plants should have vibrant, well-standing leaves.

Withered leaves, what does that mean?

This means that they are soft and tend to fall down.

It is a sign of poor general health.

But, don’t just focus on the foliage, but look everywhere: the problem is in various places.

In particular the roots which are probably asphyxiated.

Here are some leads:

Poorly drained land

A soil that retains water forms a compact mass on the roots.

That does not let them breathe, they are then asphyxiated and no longer play their role.

The plant gradually suffocates.

Consequence: the foliage withers and rots.

If you have clay soil that drains poorly, the trick is to mix it with sand or add some gravel to aerate it.

Excessive watering

It is often the fairly young plants that are prone to wilting, especially when they are watered too much.

We want to do well, but the result has the opposite effect. We downright drown the young root system.

If the weather is not good, the leaves will wither and rot, leading to the death of the foot.

The remedy is simple: space out the waterings.

The « black ass » disease

The « black bottom » disease, also called « apical rot », forms a large soft black spot on the bottom of the fruit.

This spot can cover half of the fruit. It remains edible provided the rotten parts are removed.

It is the lack of calcium that leads to this disease. It may be present in the soil, but poorly absorbed by the plant.

The reason ? The plant has irregular watering.

Be sure to provide regular and constant watering to the tomatoes so that the soil is moist, but not soaked.

3. Why are my tomato plants turning white?

tomato leaf turning white cause and solutions

Turning white tomato leaves are a sure sign of a fungal disease.

That is to say, a small fungus that settles around the veins of the foliage and devastates it.

Here are some diseases and their treatments:

fungal diseases

Powdery mildew, tomato mold, mildew, or white dew are among the most common vegetable garden diseases.

Often linked to excess water in a hot environment…it’s paradise for the development of bacteria and fungi.

They cause the leaves to yellow or whiten…but the veins remain darker.

Fortunately, these diseases are fairly easy to treat, especially with this natural remedy, the recipe of which we give you here.

Golden rule: Do not forget to space the feet sufficiently between them so that the sun passes between each one.

This avoids contamination from plant to plant.

Tomato chlorosis

In Greek chloros means « green ».

Chlorosis is a disease caused by a virus that causes iron deficiency.

It is often linked to too calcareous soil.

It is recognized by spots of a green different from the leaf to the point that it is marbled.

The spots eventually spread throughout the plant.

Result: we notice the underdevelopment of the seedlings and a very late maturation of the fruits.

It can be treated by adding minerals and organic matter to the soil such as iron with dried blood powder for example.

Too nitrogenous soil

Rich soil is good…but too many nutrients can have the opposite effect on your vegetables.

The tomato hates excess nitrogen. It turns the leaves white.

To correct this excess, you can add a few handfuls of heather soil or peat.

The weaver spider mite

It is also called « red greenhouse spider ».

It is a pest that lives in colonies and weaves a web under the leaf preventing it from developing normally.

To the naked eye, it looks like a cottony red spot on the tomato plant. Foliage loses its normal green color.

Do not panic, we can get rid of it naturally.

A decoction of garlic to be sprayed on the affected areas is effective. Provided to renew the treatment every 3 days.
