Green Leaves Have Yellow Veins: Reasons For Yellow Veins On Leaves


By: Amy Grant

If you have a plant with yellow veins on the leaves, youmight be wondering why on earth the veins are turning yellow. Plants use thesun to make chlorophyll, the stuff they feed on and responsible for the greencolor of their foliage. Paling or yellowing of the leaf is a sign of mild chlorosis;but if you see that your normally green leaves have yellow veins, there mightbe a larger problem.

About Yellow Veins on Leaves

When a plant’s foliage creates insufficient chlorophyll, theleaves become pale or begin to yellow. When the leaves remain green and onlythe veins are turning yellow, the term is called veinal chlorosis.

Interveinal chlorosis is different than veinal chlorosis. Ininterveinal chlorosis, the area surrounding the leaf veins becomes yellow incolor while in veinal chlorosis, the veins themselves yellow.

Along with this major difference, the causes of chlorosisdiffer. In the case of interveinal chlorosis, the culprit is often a nutrientdeficiency (often an irondeficiency), which can be diagnosed through testing and usually fairlyeasily remedied.

When a plant has leaves with yellow veins due to veinalchlorosis, the culprit is often more serious.

Why Do Green Leaves Have Yellow Veins?

Pinning down the exact cause of yellow veins on leaves maytake some serious sleuthing. Veinal chlorosis is often the next step in seriouschlorosis issues. It may be that your plant was lacking in iron, magnesiumor other nutrient and conditions went on for so long that the vascular systemof the plant started shutting down, no longer creating chlorophyll. A soiltest can help determine if the plant is lacking in nutrients and, if so, aproper amendment can be made if it isn’t too late.

Another reason for leaves with yellow veins is insecticideor even herbicide use around the plant. If this is the case, there isn’t toomuch that can be done, as the plant has essentially been poisoned. Of course,in the future, restrict or eliminate the use of these chemical controls aroundthe plants.

Another reason for green leaves with yellow veins might bedisease or injury. Several diseases, such as certain species-specific mosaicviruses, can restrict the uptake of nutrients which may result in yellow leafveining.

Additionally, soil compaction, poor drainage, root injury orother damage can cause veinal chlorosis, although this is usually precipitatedby interveinal chlorosis. Aerating the soil and mulching may provide somerelief to a plant that has yellow veins on leaves.

Excess Water

Symptoms: The leaves look yellow and pale, apart from the fact that you know perfectly well how often you water your tomato plants. Excess water causes the roots to rot (little by little) and can also cause fungus.

Solution: If you have a pot and you can put drainage without suffering much the plant, well, if not you already know for the next time. If it is a pot or container, check that it has holes in the bottom and raise the container a few inches off the ground, so the water will be eliminated little by little. You can also add sand to the substrate to absorb excess water.

Lack of Water

Now let’s go to the opposite of the above.

Symptom: The leaves dry out and some of them are crunchy.

Solution: Water with more water and more regularly, remember that the water must penetrate to the root so that it can be absorbed. Also, try to avoid the hottest hours of the day, you may water correctly, but most of it will evaporate.

Lack of Light

How I detect it: The leaves look discolored and decayed. Keep in mind that the ideal is 5 hours of sun, so that the tomatoes evolve correctly, although with some less they also develop.

Solution: Change the location of your plants. If they are planted in the ground, and already have a flower, forget you should not repot it because surely, you will ruin the fruit and it is not worth it, try to pamper them so that they evolve and give fruit in the place you have them and for the next plantation you already know to write it down.

Leaf-eating Insects

How you detect: Usually under the leaves, there are small insects that devour the leaves or suck the sap leaving it yellow until it becomes transparent.

How you can solve it: Use an ecological insecticide such as Neem oil or you can apply potassium soap.


Nitrogen deficiency may cause yellow leaves on tomato plants. The first symptoms usually affect older, more mature leaves, and gradually the yellow color progresses to more and more leaves. Young leaves tend to stay green but may be smaller in size. In some cases, a red or purple cast can be seen on the veins. Usually, applying nitrogen fertilizer helps the new growth grow normally, but already yellowed leaves will not become green.

Sulfur deficiency can cause yellowing of the leaves. The symptoms can be easily mistaken for nitrogen deficiency because leaves the yellow and veins take on a reddish tone. However, leaves usually retain some green color the yellow color is more uniform over the whole plant rather than just the older leaves. The red color is often found on the underside of leaves, and the petioles take on a more pinkish tone. The red coloring is less pronounced than with a nitrogen deficiency. The yellow leaves may also become distorted, brittle and twisted as the deficiency goes uncorrected. Sulfur is usually found in most commercial fertilizers.


Causes of Abutilon Leaves Turning Yellow

If you are a plant lover then you might know how frustrating it is to see your plant leaves turning yellow. As I mentioned above the several potential causes of abutilon leaves turning yellow, now you need to know them in detail.

Don’t worry, I’ll walk you through to identify the potential causes also how you can fix them.

Without further ado let’s dive in.

Potential Cause: Overwatering

Unfortunately, many indoor gardeners make mistakes while watering their abutilon. As a result, soil waterlogging can occur and a dangerous disease called root rot can develop. Root rot holds up the nutrient intake and abutilon leaves start to turn yellow.

Wet and humid conditions are favorable for fungal diseases. Root rot is caused by fungal agents and it becomes very difficult to save the infected plant. However, if you can identify before it’s too late you might save your abutilon from dying.

Signs of overwatering

Now, how do you know that your abutilon is suffering from overwatering? Well, all indoor plants have built-in “indicators” that signal a shortage or excess of certain mineral components, sunlight, oxygen, or water in the soil.

You just need to carefully look at your green pet. Here is one of the most important indicators of overwatering your abutilon plant.

Abutilon leaves began to fade and start yellowing. This occurs at the initial stages of waterlogging. Even the most experienced gardeners think that the plant thus indicates a lack of moisture in the soil, which is why they begin to water it even more intensively.

However, if there is a lack of water, your abutilon leaf tips will dry first. Keep this in mind, it will save your plant.

How to fix

Now, the question is how you can fix the overwatered abutilon. You need to be very careful when dealing with an overwatered abutilon. Here is what you can do to fix it.

1. Try to Drain The Soil

First, try to drain out all the moisture from the soil. Many gardeners will say that the first thing is to transplant the plant into a new container with a dry substrate.

However, do not forget that for a diseased plant, such a procedure can become extremely fatal. Therefore, you should try to drain the soil.

Some plants are not allowed to be transplanted at all.

To do this, move the plant to a new location. It should be warm, the sun should fall on it. The abutilon loves partial shade. So, create an additional source of shading.

I would recommend removing the yellow leaves from the plant. Then the plant will utilize more water to grow new leaves and buds. However, do not place your abutilon pot on the stove or radiators, so as not to burn the root system!

2. Transplant abutilon into a new substrate

Now, you need to bear in mind that the transplant procedure does not harm abutilon in any way. However, consider the fact that you have to replace the entire soil mix.

It is important to remove not only the whole earth but also parts of the root system that have been infected by root rot. You should also choose a new container for planting or treat the old with boiling water.

To make the root growth faster, you can treat them with growth stimulants. Make sure you add some soil substrate to make it more breathable for abutilon roots. For example, you can use sawdust or peat.

However, keep in mind that after transplanting you must not water the soil for several weeks. In addition, it will be necessary to take special care for your abutilon.

3. Proper Care for the Plant

If you have managed to save your abutilon from root rot, congratulations! You just have successfully completed the hardest part. Now, your abutilon needs more care for a few days after transplantation.

So, When exactly do you start to water the soil? This is the question that most concerns the indoor gardeners. Experts recommend starting this only when the topsoil is dry.

However, you must do this in small portions. As for the application of fertilizers, you should not carry out within two to three months. An exception may be the entry of a plant into the flowering phase.

Now, let’s move on to the opposite cause of overwatering that can cause yellowing abutilon.

Potential Cause: Lack of water

In the warm season, abutilon needs abundant watering. In this case, you do not need to wait until the soil surface in the pot begins to dry out.

In summer insufficient water can cause loss of buds and the whole plant looks unhappy due to the death of some roots.

Like other plants, abutilon also needs enough water to maintain physiological processes.

If your abutilon does not get enough water, it will start to show symptoms yellowing the leaves.

Yellowing leaves and shedding them is a plant defense mechanism against water stress.

In this way, your abutilon tries to save water reducing the number of leaves. Because the more the number of leaves more the transpiration (way of cooling down).

How to Fix

In order to restore your abutilon and return its former green charm to its leaves, it is necessary to water moderately and frequently.

You can determine water requirements inspecting the plant and soil. You have to make sure the regular supply of water to the root system. Water your abutilon when the topsoil starts to dry.

Potential Cause: Temperature Fluctuation

Abutilon has it’s comfortable temperature range to grow indoors. If you do not ensure proper temperature it will respond by yellowing of the leaves.

The optimum temperature level for abutilon in summer is 22°C/71.6°F to 25°C/ 77°F. In winter you should maintain 12°C/53.6°F to 15°C/59°F.

Now, If the thermometer drops below 12°C/53.6°F, then this can trigger the yellowing of your abutilon leaves.

How to Fix

Temperature change is very crucial for indoor abutilon. Do not keep your plants where it gets the direct cold flow of the air conditioner.

The cold drafts can harm abutilon badly. Keep your abutilon away from the cold draft of the window. Also, the direct flow of the radiator in winter will cause your plant to wither and turn yellow.

Misting can help Abutilon thrive, if the humidity is low in winter.

Potential Cause: Insufficient Light

Lack of light is one of the common causes of abutilon leaves turning yellow. You might know that the leaf is green due to the presence of chlorophyll.

Plants harvest sunlight to make food for themselves through the photosynthesis process. Chlorophyll plays the leading part in the photosynthesis process with the help of light.

Now, if you can not ensure enough light for your abutilon, the chlorophyll will start to degrade. Therefore, abutilon leaves will turn yellow.

How to fix

If your abutilon is in a dark place or not getting enough light then you need to consider changing the placement of it. Place the plant in a place where it gets sufficient indirect sunlight.

When you place your abutilon in an open place for light, you should shade it for a few days. Eventually, it will adapt to the changing environment. Remember direct sunlight will cause sunburn of the leaves.

Also if your apartment does not get enough sunlight then consider using artificial light for your abutilon. The plant can do photosynthesis in artificial light without any issues.

Potential Cause: High Soil pH

Abutilon likes slightly acidic soil. So, if your potting mix for abutilon is alkaline or high in pH, then your plant leaves may turn yellow.

Alkaline soil is not good for nutrient availability, vital nutrients like iron, manganese, zinc are not available for plants in high pH. That’s why abutilon leaves turn yellow and fall off.

How to Fix

Maintaining desired soil pH for abutilon is important for better development and growth. In slightly acidic soil ( below pH 7.0) makes plants happy. Because within this range of pH plants can intake the essential nutrients from the soil.

How do you know your soil pH? Well, in the present-day everything became so easy. Just grab a soil pH meter (Amazon link) from the garden store. This instrument is very easy to use.

I often recommend gardeners to water abutilon plants with little bit lemon juice if the pH is high. Lemon juice or citric acid helps plant soil to reduce the pH level.

Potential Cause: Lack of Nutrients and How-To Fix

The plant needs the micronutrient elements for growth and development. If there is a lack of these nutrients then your plant will show symptoms like yellowing of leaves.

Following deficiency of nutrients cause abutilon leaves turning yellow:

Iron deficiency

You will notice uniform yellowing between the abutilon leaf veins due to iron deficiency. Symptoms appear primarily on young leaves. Veins remain green.

Then the color of the upper leaves becomes pale green or yellowish, sometimes whitish. Subsequently, young leaves grow pale green or whitish including veins.

How to fix

Use chelated liquid iron on plants. Check out chelated iron on Amazon. You can either spray on abutilon leaves or water with it.

Magnesium deficiency

Magnesium is a mobile element in a plant. So, when it is deficient, it moves from old leaves to young ones.

Therefore, old leaves of abutilon start yellowing. The leaves turn yellow from the edges of the leaf plates. Gradually, the whole leaf becomes chlorotic. Only the vein and adjacent area remains green.

If you do not address this issue, the edges of the leaf blade turn down, the leaf looks convex, curly.

How to Fix

Topdressing with magnesium sulfate according to the instructions.

Zinc deficiency

You’ll see adult leaves of your abutilon turning yellow because of zinc deficiency.

You may also find leaf spots in addition to the yellowing of leaves. Young leaves first grow small with yellow dots and then acquire a yellowish faded color.

Lack of nitrogen

With a lack of nitrogen, yellowing and lightening of the color begin with the veins and the adjacent part of the abutilon leaf plate.

Without nitrogen plants can not make chlorophyll, therefore abutilon leaves turn yellow. If your abutilon leaves turn yellow due to nitrogen deficiency, there will be no green veins.

The difference between a leaf with nitrogen chlorosis and an old one is that with aging, yellowing develops evenly. And leaf veins remain green, they turn yellow lastly before falling off.

How to fix

Apply Nitrogen fertilizer as per instructions.

Lack of sulfur

Signs of a lack of sulfur are similar to signs of a lack of nitrogen, appearing on young leaves of abutilon. Yellowing begins with the main veins of the upper leaves, later the entire leaf plate is involved in the process. And the veins look more green against the background of a yellowed leaf.


Viruses

Several untreatable viruses occur in tomatoes, causing severe foliar damage. Alfalfa mosaic causes yellow leaf blotches and mottling -- it is most common in tomato plantings near alfalfa fields. Curly top virus causes plants to stop growing completely, develop yellow leaves, stiffen and die any green tomatoes redden regardless of their stage of development. The tomato infectious chlorosis virus causes yellowing between the veins of tomato leaves that may also roll, eventually these leaves become thick, crisp and brittle. Tomato yellow leaf curl causes widespread leaf curling and yellowing, although veins may remain green. Affected plants are stunted and often fail to fruit.
