However, the problem with petunia is that they often start to wither and wither.
After doing a lot of research, I have finally furnished myself with the reasons and causes of this problematic situation.
Petunias are extremely popular flowering plants that grow amazingly in pots as well as bedding garden plants.
With a diverse variety of colors, these flowers can be found in any specifications you desire. These blossoms light up your summer garden with vibrant colors, which is indeed a treat to the eyes.
However, with these beautiful flowers comes a troubling situation of sudden death and wilting.
Generally, it has an easy fix, but sometimes, dying petunias are a sign of something serious. To know what causes your petunias to die and find solutions for how to fix them, keep reading this article.
Why are my petunias dying?
Petunia is a very beautiful garden flower that is easy to grow and maintain. The only problem with the flower is its sudden withering that often makes gardeners worry. Take a look at some reasons why your petunias are dying:
Dying petunias can be a sign of too much water. When the soil around the flower is overly damp, it causes it to wilt.
Overwater petunias are a very common mistake gardeners make.
Waterlogged conditions hamper the drainage of the flower. If there is too much water in the soil around the plant, there is a possibility of the flower drooping.
Contrasting this reason, another potential cause of dying petunias is under watering your plant. When the soil around your plant is not properly watered, an insufficient amount of water reaches the plant making it deficient. This results in the plant dying.
The soil condition is related to the water requirements.
If you overwater your plants, the soil around them will get water-clogged, not allowing proper drainage. This will lead to the development of fungus and attack your plant’s roots, making it wilt.
Similarly, soil that is not well-watered will not be able to nourish the flowering plant with the required amount of water and nutrients.
As a result of which the plant will dry out and eventually die.
Check if your flowers are overgrown.
Overgrowth in petunias results in weak and leggy flowers, making them appear like they are about to die.
To overcome this situation, you have to cut the areas of overgrowth and damage, which is approximately half the flower’s size, and you will be able to remove the weakened parts as well as allow newer growth.
Lack of nutrients is another potential reason causing your petunias to die.
If the soil where you have planted your petunias is of poor quality and is unable to provide the flower with the amount of nourishment it requires, your flowers are likely to die.
Due to the vigorous blooming habits of petunias, a lot of nutrients are necessary for sustenance.
Fertilizing your soil regularly will help to solve this issue.
Fertilizers boost the quality of soil, encouraging more substantial growth with enhanced quality of flowers. Therefore, you can make up for the deficiency in nutrients with an adequate amount of fertilizers.
Petunias are very prone to diseases and fungi. As gardeners, our job is to identify these diseases and find their proper cure.
Botrytis Blight causes discoloration leading to brownish-grey spores. This disease is a result of overwatering the soil, making it waterlogged.
Petunias often develop powdery mildew when there is not enough room for proper ventilation.
Flowers that are too close to each other constrict the airflow and lead to this problem. You should look for white, powdery spots and spores that cover the leaves and flowers completely.
Fusarium is a common problem in petunias. It is a fungus that attacks the roots of the plant and drains away from the water essential for it, making the petunias dry out and die.
This is one disease that cannot be treated. Petunias that are infected with this fungus should be carefully pulled up from the soil and disposed of. The area in the soil should be covered with dark plastic in summers allowing the heat to kill the fungus.
Insects and fungi
Insects and fungal attacks are some of the most common reasons that cause our petunias to die.
Insects like Aphids, budworms, and slugs feed on petunias, creating spores in the leaves, making a pathway for the disease. Discard slugs from your garden. Spray insecticides and pesticides for aphids and budworms.
Diseases like white mold, gray mold, black root rot, and verticillium wilt can cause the plant to die.
These disease-causing insects can be carefully gotten rid of if your petunias are watered regularly, early in the morning.
This will ensure that the water does not sit on your leaves or flowers for a long time, making them prone to infections. If your petunias are attacked by fungi, remove the damaged parts and apply fungicides.
How do you revive a dying Petunia?
Reviving petunias is an easy task. It requires some time and patience. A lot of causes lead to dying petunias. Our first and most important job is to identify the cause. After that, it is merely a work of taking corrective measures to cure your flowers.
These are the following ways you can revive dying petunias:
Soil condition is the most important attribute of your petunias. Water-clogged soil will lead to fungal infection, and dry soil will lead to a lack of nutrients.
Therefore, to revive your plants, get the optimum soil requirements.
You can re-pot if the situation starts getting out of hand. Otherwise, add fresh soil to the plant till it starts improving.
Keep up with your watering schedule regularly, and soon you will have good quality flowers. Petunias grow best on acidic soils with a pH of 5.4 and 6.0.
Too much proximity often constricts airflow leading the flower to catch diseases. Aim to have a lot of space between your flowers so that they have enough places to breathe.
Cut back foliage
We often end up with poor quality petunias that die quickly of overgrown plants.
Prune your plants to the tip of the pot, removing all the dead bloomed and withered leaves. This will significantly help revive the petunias, and only in a few weeks will your petunias be as good as new.
If you have problematic soil, use fertilizers, insecticides, and pesticides to solve your problem.
Fungal infections can be treated with the help of neem oil. Add a sufficient amount of fertilizers and revive your petunias quickly, without much trouble.
These were some of the techniques by which you can quickly revive your dying petunias and get a good-quality flower.
The process is relatively easy. Have patience, and you will soon see the results for yourself.
Why do petunias suddenly die?
If your petunias are abruptly dying, the first thing you need to do is find the cause behind it. There are many possible reasons why your petunias are suddenly dying.
Verticillium wilt is a fungal infection that is very common in petunias. The edge of the leaves starts turning yellowish-brown. Eventually, the plant starts to dry and finally dies.
To cure this, you have to trim the affected parts of the leaves and allow newer growth. Further, keep in mind to have the soil clean of any plant debris.
Another possible reason is the ineffective water and soil situation. Over or underwater, your petunias will lead them to wither. Also, take a look at the growth.
If your plants are growing too much, cut down the growth as it makes the plant inferior in quality.
Free your garden from plant feeders like slugs and snails as they eat up your plants and allow various diseases to form inside of them.
Healthy petunias are rarely affected by pests or insects. You should plant petunias in porous, well-draining soil where there is an adequate amount of sunlight.
When bloomed properly, petunias are a summer delight! Water the plants thoroughly once a week in hot weather, allowing the moisture to penetrate 6 to 8 inches in the soil.
Keep a frequent eye on your petunia tubs or hangers, as in the summer season, the soil tends to dry out faster than usual.
Petunias are flowering plants; therefore, they need heavy nourishment to sustain.
Incorporate the right amount of fertilizers into the soil to enhance the growth of your petunias. Regularly feed the plants throughout the entire season by adding one tablespoon of water-soluble fertilizer in one gallon of water.
Petunias lighten up the garden with their vibrant variation of colors during the summer season. These flowers are a great piece of decoration for your garden.
These flowers thrive with little care. Nevertheless, the issue of dying and withering petunias can be troublesome, especially if you are a beginner.
