How To Cut Back Petunias. 3 Things To Master

Knowing how to cut back petunias is not limited to trimming, but it also encompasses deadheading and pruning heavily. As a gardener, you must master these maintenance practices to rejuvenate your petunias and encourage healthier blooms. This way, your plants will grow much more vigorously, and you may enjoy an extended blooming period. 

The good thing with petunias is that they are also generally easy to grow. Therefore, the maintenance of these plants will not be meticulous and demanding. However, it might still be beneficial to provide petunias a stable environment such as the greenhouse if your climate gets extreme. 


How To Cut Back Petunias. 3 Things To Master

Comprehensive Guide On How To Prune Petunias


Technique #1. Deadheading

The first technique that you must master to prune petunias correctly is deadheading. Sometimes, cutting back refers to merely the removal of faded blooms on your petunias. Like other flowering plants, petunias will benefit from deadheading because removing the dead blooms will help them grow healthier flowers. 

This way, the plant gets to focus its energy on making new flowers since the faded blooms don’t compete with the new ones. You’ll also be preventing seed formation, so the flowering season gets longer. And as a bonus, removing the faded flowers on petunias will keep them looking neat throughout the season. 

When should you deadhead petunias? You’ll notice petunias that have faded flowers during the flowering season and will begin to wilt downward. Their colors look less lively, and instead of the trumpet and upright shape, they hang low. 


Pinch or snip

To remove these old blooms, use your thumb and index fingers to pinch the stem behind the blossom. This will make it easier to pull the dead flower from the plant. Continue checking your petunias and remove the wilted flowers by hand.

Some gardeners also use scissors to remove the faded flowers. However, be sure that you disinfect it first, and it’s sharp enough to provide a clean cut on the stem behind the bloom. Any plant is prone to acquiring diseases and fungal infections if the tools are not sanitized. 


Technique #2. Trimming

Another way to cut back petunias is to do it lightly by trimming them. This is an ideal maintenance practice to maintain their size and shape and also rejuvenate the plants. Trimming petunias is no different when trimming other plants as well. 

You want to choose an area where smaller stems branch from the main stem and cut them close to the node. Choose those stems that no longer produce flowers or have an underwhelming amount of foliage and trim them. Much like with deadheading, trimming these branches can encourage flower production. 

You’ll also help rejuvenate the plant and develop new growth that has healthier foliage. You can trim your petunias in the middle of the summer with sharp and sterile tools as well. Be mindful of providing a clean cut to avoid disease transmission among plants. 


Technique #3. Cutting back

Finally, cutting back petunias all the way through the entire plant is perhaps a heavier way to trim them. Sometimes, deadheading nor trimming will not be enough to rejuvenate the plant. Cutting back the plant to the ground can help you regrow leggy petunias with underwhelming blossoms and yellowing foliage. 

To cut back petunias heavily, you want to start above the stem node with sterile and sharp pruners. You can prune as far as you like depending on how long and overgrown the stem is. Just remember that the branches are two inches from the base to allow the plant to generate new growth. 

More so, remember that some plants only produce flowers at the end of the stems, and these petunias will benefit if you clip some branches weekly as soon as you planted them. Don’t be afraid to remove stems and cut above a node even though they bear gorgeous-looking flowers. Over time, you’ll notice new growing tips below where you cut, and they will bear healthier flowers. 



How To Help Your Petunias Regrow

You can further encourage your petunias to regrow if you keep them in the ideal environment and perform maintenance practices to keep them healthy. Suppose your region experiences challenging weather or harsh temperatures; consider keeping the petunias protected in the greenhouse. You must also maintain soil moisture without letting the medium gets soggy. 

Proper hydration will help your petunias recover from pruning quickly. Some gardeners also fertilize their petunia to boost their blooms. Depending on the type you have, you can feed every two weeks in July. 



Petunias are one of the best flowering plants to grow, but they require maintenance to ensure healthy growth. Therefore, you must learn how to cut back petunias and master the three techniques, which are deadheading, trimming, and cutting back itself. Pruning petunias will rejuvenate the plants’ leggy growths and even produce better-looking flowers. 

You can pinch or snip off the faded blooms to deadhead petunias, and this should maintain healthy-looking plants during the season. On the other hand, light trimming will suffice when you notice branches with underwhelming foliage and flowers. And lastly, you may need to cut back your plants heavily if the previous two techniques don’t lead to changes. 

Overall, just remember to sterilize your tools and check for their sharpness. This will ensure a sharp and clean-cut for the neater end product and prevent disease transmission among the petunias.

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.
