How To Revive Dying Petunias Successfully

Gardeners must know how to revive dying petunias by watering and cutting. It can be discouraging to see your flowers dying, but you can rejuvenate them back to health with proper techniques. You can also use a greenhouse to ensure that your plants live in an optimal environment and keep your colorful flowers thriving. 

Petunias are annual plants, but if you’re planting zones 10 to 11, it’s better to grow them as perennials. However, this makes them prone to becoming leggy in the middle of the summer. What’s great with these plants is that proper maintenance and care should bring them back to their glorious condition.

Two Best Ways On How To Revive Dying Petunias


#1. Watering

The first practice that can help revive dying petunias is as simple as watering. Sometimes, your plants don’t require cutting back, and watering should be enough to support the flowers to return to good health. But how would you know that watering is enough for dying petunias?

Typically, petunias with wilted and floppy flowers and leaves are just dehydrated and will benefit from watering. Add moisture to your soil so that the roots absorb the water quickly. If done right, your petunias should look better within hours. 

However, while this is a quick and straightforward solution, it’s more ideal if your plants do not experience wilting often. Petunias that wilt frequently will eventually get damaged because of the stress. Therefore, make it a habit to saturate the soil to the root level twice a week.

 If you are growing on containers, watering can be every day. Check when there are signs of wilting or if the soil looks dry. If you notice that the ground gets very dry and they pull away from the sides, submerge the pot in water until bubbles cease. 


#2. Cutting

Your second option for reviving dying petunias is cutting. This practice would be more suitable if your plants have passed the stage where watering isn’t enough to restore them. What signs should you look for in your petunias that signals cutting is appropriate?

Check the foliage of your plants and if they look dry and crunchy instead of wilting. Watering won’t be appropriate at this stage, but cutting or trimming the vegetation should do the trick. Depending on how much foliage has dried, you can trim your plants back at one to two inches of the base. 

After trimming, don’t forget to water the soil to help the plants further. You should expect new growth and blossoms after weeks as long as you water them well. Emphasis is necessary with watering because even after cutting, plants would not bloom and might die within days if they are dehydrated.

Cutting back the foliage when you notice brittle and yellow or brown leaves can help revive them. This practice is more common halfway through the summer, and shearing them back should help get a healthier new growth. Pinching off dead blooms or stems as soon as they wilt could also encourage flowering and force the plant to produce a fuller growth.


How To Prevent Petunias From Dying

As you can take from the previous information, watering plays a significant role in petunias’ health. It’s the common reason why the plant’s wilt, and even after cutting, plants will cease to recover if you failed to water them afterward. Therefore, adequate water is the primary practice to help prevent petunias from dying.

Like with other plants, you should also maintain the ideal conditions of petunias to keep them healthy. The greenhouse makes an excellent environment for all flowers alike because you control the temperature, light, and pests much more comfortably. You can also monitor your petunias quickly compared to growing them outdoors. 

The greenhouse can protect your petunias, especially during summer, where the heat can get intense. You can use watering systems to ensure that all your plants receive their water requirements in addition to having a cooling system if necessary. Overall, prevention and quick intervention should prevent petunias from dying. 

Do not forget to water petunias with an inch of water weekly and apply fertilizer at midseason. Mulching should also help in keeping the soil cool and hydrated to prevent heat stress. Lastly, you might need to use a greenhouse shade if the sun gets too harsh for the plants. 



Growing petunias in the greenhouse should ensure that your plants stay healthy and glorious-looking. But do you know how to revive dying petunias when you saw the signs? Don’t panic because watering and cutting petunias should rejuvenate your flowers back to life. 

Watering should be your first step and immediate response when you notice your foliage wilting. Petunias should bounce back after watering, and diligence should quickly help you prevent dehydration and wilting. Lack of water is the most common cause of dying petunias, so water the plants responsibly. 

Otherwise, dried leaves and brittle foliage means that cutting back petunias are the more appropriate response. After you trim the plants, remember to water the soil to support the new growth. Using a greenhouse should also help you maintain the plants, regardless of the weather. 

Adjust the conditions indoors and always monitor your petunias for signs of wilting or drying.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
