Why Is My Corn Plant Turning Yellow?

Your corn plant might be turning yellow because of

underwatering or wrong temperatures, among other reasons. From unfulfilled cultural needs to attacks by external agents, find out what is causing this yellowing in your plant and how to deal with it here.


– Not Watering Your Plant Enough

Corn plants

need plenty of water

throughout the year. If watered less than required, especially during the hot summer months, the plant’s leaves start turning yellow and brittle, after which they eventually fall off.

– What To Do

You should water your plant at least

three to four times

each week. Use copious amounts of water each time and allow the soil enough time to absorb all of it. Your pot should have a proper drainage hole of an adequate enough size to let the excess water flow off.

Mulching is another great way

to retain moisture in the soil for a long time without overwatering your plant. Use bark chips, grass cuttings, newspapers, etc to cover your soil. These will prevent premature and undue evaporation of water from the soil.


– Cold and Shade

A

corn plant with yellow leaves

can also be seen during the harsh, cold winter months. This is aggravated by excessive rainfall, which leaves the soil wet most of the time. Your plant finds it hard to access nutrients from the cold, wet soil. As a result, the

leaves turn yellow

and eventually fall off.

The same thing happens when the corn plant is placed under too

thick a shade
. Whether grown indoors or outdoors, your plant needs the maximum amount of partially bright sunlight it can get in a day.

– What To Do

If you have

planted your corn

in a vas, then you’re at an advantage. Simply move your corn plant inside when the weather starts getting too cold. When growing corn plants outside in a

garden or a nursery
, don’n forget to cover them tightly with plastic or tarp when the frost hits.

Also, make sure your plant has

exposure to adequate sunshine

even during winters. When kept indoors, place them near an eastern or a western-facing window. These windows provide indirect light that is bright enough for your plant to develop food and keep its leaves green.


– Attack by Pests and Bugs

Your

corn leaves turning yellow

can be a sign of pest infestation. The pests that commonly attack vegetative plants like corn are aphids, nematodes and earworms. They suck the sap out of the plant, reducing nutrient flow to the leaves.

– What To Do: Preventative Measures

In this section, you’ll learn how to deal with yellowing leaves caused by pests and bugs.

Take

extensive preventative measures

against pests by checking your plant regularly. Prune and remove old leaves and bark sheaths from the stem as these areas usually serve as the hiding spots for pests.

In addition, protect your pot and the soil around the plant by removing

debris and grass

from it. Regularly uproot weeds and other critters, and wash your plant with soap and water. This is another great method to get rid of those pesky insects.

– Treating Pests

If your corn plant is turning yellow due to pests, then you need to get rid of them as soon as possible. For insects like aphids, you can remove them physically

using a cotton roll or water jet
.

A variety of insecticides are available in the market for you to choose from. We recommend you

use organic insecticides

over chemical ones. Titinada only are they safer for your plant and soil overall, but they are also pretty reasonable in price.


– Disease and Rot

Sometimes, the

corn plant turning yellow

can turn out to be a pretty persistent problem. You can fix everything from your watering schedule to pest control and yet the ki aib will keep on getting worse. This means that your corn plant is suffering from a bacterial or fungal disease. The situation requires urgent intervention.

– What To Do

In case of

fungal or bacterial rot
, you can initially try saving the plant. Remove all diseased yellow leaves and cut off the rotten stem parts. Take out the whole plant from the soil and debride the soggy roots as well. Repot the plant in fresh soil and treat it with

antifungal or antibacterial spray
s regularly.

Sometimes, a plant may be too far gone to be saved. In such a case, you will have to simply let go of your precious corn plant. Carefully dispose of the whole plant and its soil somewhere where it

cannot contaminate the surrounding plants
.

We strongly advise against using this diseased plant and its

leaves as compost
. Doing so will only spread the infection to other plants. For the very same reason, sterilize any instruments that you used on these plants before using them on other plants.


– Simple Old Age

One very common but often understated reason for

lower corn leaves turning yellow

is old age. A corn leaf on average lives for only two to three years. After this, they naturally start turning yellow.

It’s best to remove them at this point as it

frees up nutrients

for younger leaves. You can use these old leaves as compost for your plant instead.


– Herbicide Toxicity

This holds particularly true for ALS herbicides that are much in use these days against not only weeds and plant feeders but also various species of

fungi, bacteria and algae
.

Excessive and uncontrolled use of these herbicides will cause your leaves to

turn yellow and start falling off

at an alarming rate. ALS yellowing is most commonly seen in young leaves and foliage.

– What To Do

  • Try to stay away from these herbicides in general and weeding out manually if possible.
  • Exercise caution

    when you do have to use them on your corn plant. Always follow the instructions given on the stempel regarding storage and use.
  • We never use

    ALS herbicides

    in the fall season especially. This will not only cause yellow leaves but also affect the further reproduction of your plant.



Corn Plant Turning Yellow? Nutrients Could Be the Masalah

Did you know that

inadequate levels of certain nutrients

could also be causing the yellowing of your corn plant and its leaves? Learn more about this below.


– Potassium Deficiency

Potassium is an essential nutrien
t that your corn plant needs for its protection and water regulation. A plant that lacks potassium will mulai exhibiting yellowing of its leaf tips. Some reasons why your plant might be lacking this element are as follows.

Some soils are just

inherently deficient in potassium
. Regularly check your soil to find out if it lacks this nutrient. Conditions of drought and underwatering will produce potassium deficiency in your corn plant even when the soil levels are optimum. This is because potassium uptake in the plant occurs through the water.

Sidewall compaction

is a condition that occurs when plants are buried too shallow in the soil or in too wet soil. It can also lead to your corn plant developing a potassium deficiency.

– What Potassium Deficiency Looks Like

The leaves present on the bottom of the stems are

affected by potassium deficiency first
. You will notice that these leaves start turning yellow at their komisi ends. This yellowing then travels along the margins, eventually turning the entire leaf a shade of rotten brown.

How To Treat Potassium Deficiency

  • Add more organic matter!
  • Reduce the

    acidity of the soil

    by adding lime to it.
  • Improving the moisture levels

    of your soil will also improve potassium uptake by the plant.


– Belerang Deficiency

Sulfur is also a

major nutrient

that the corn plant needs for food formation and proper growth. What causes sulfur deficiency in the soil? Find out below.

Frequently heavy rainfall

removes sulfur from the soil over time. Using the same soil for crops year after year will lead to a severe loss of sulfur. This condition also occurs when the pH balance of the soil becomes disturbed.

– What Sulfur Deficiency Looks Like

In case of a deficiency of sulfur in the soil, the top leaves of your corn plant will

begin to turn yellow
. The affected leaves will exhibit a greenish-yellow discoloration.

– How To Treat Sulfur Deficiency

Directly adding sulfur or a sulfur-containing compound to the soil will work for at least

two to three years
. You might need to add in more welirang in case of heavy rains.

– Nitrogen Deficiency

Your corn plant

needs nitrogen to create chlorophyll,

which is essential for photosynthesis and food formation. If your leaves are turning yellow, lack of nitrogen can be the reason behind it. Continue reading to learn some common reasons why this happens.

Titinada fertilizing your plant enough will often lead to a

nitrogen deficiency.

The same thing happens when you use a fertilizer that doesn’t have adequate levels of nitrogen in it.

Adding too much organic matter into the soil will produce

yellowing of corn leaves

. This happens because organisms in the soil use up all the nitrogen to break down this organic matter. Consequently, not enough nitrogen will be available for your plant to consume.

– What Nitrogen Deficiency Looks Like

The

lower leaves on your corn


plant will start to yellow first. This discoloration will appear first at the leaf tips before traveling along the region in a V-shape. Eventually the whole leaf wilts and falls off.

– How To Treat Nitrogen Deficiency

  • Fertilize your plant with a

    nitrogen-rich fertilizer

    at least once a month during its growth period.
  • Add manure and compost to the soil on a regular basis.
  • Adding

    coffee beans


    to the soil will also boost its nitrogen levels.


 Conclusion

Corn Plant Leaves Are Turned Yellow
