How To Trim Petunias. The Best Guide

You can learn how to trim petunias easily, but it’s crucial to know what to consider, when to trim petunias, and why we should trim petunias. Trimming, removing faded flowers, or deadheading are practices that should keep your plants healthy and blooming beautifully. However, this doesn’t mean that your plants will require heavy maintenance; remember that some petunias are self-cleaning as well. 

You can also grow petunias in the greenhouse for added ease in maintenance. Compared to having petunias outdoors, you can keep them in a stable environment and avoid potential problems. More so, gardeners can find it more convenient to trim petunias in a greenhouse because it’s easier to monitor the plants indoors.

How To Trim Petunias: Three Questions To Ask

The trimming procedure of petunias is straightforward. You will cut back the tips two inches above the leaf sets at planting time. You can also pinch the tips by hand, and this will have the same result, which is encouraging the branching of the plants. 

But besides during planting time, pruning and pinching petunias are also feasible once a month while making sure to leave a set or two of leaves. Some gardeners cut ⅕ of the total length of stems as a maintenance practice because petunias can be prone to becoming leggy and having trouble in growing. When you cut these leggy and unproductive stems, you can help your plants focus their energy on creating new growth. 

According to the University of Vermont, you must also remember that some varieties don’t require cutting back to rebloom. The newer smaller petunias in the market can drop their own flowers, so you don’t need to deadhead them to continue blooming. On the other hand, the larger and double types of petunias will require deadheading for extended blooming and aesthetic purposes. 

 

Question #1. What to consider when trimming petunias?

As mentioned earlier, you must check the variety you have if it will need pruning. Generally, smaller petunias don’t require trimming compared to larger plants. This is why spreading petunias won’t require pruning because you intend to have them over the landscape or spill on planters, but mounding and Grandiflora varieties need trimming to look better and thrive. 

However, you may find that your plant will benefit more if you prune leggy and overgrown stems regardless of the variety. As with any other plant, letting them overgrow will not only look bad visually, but it also makes flower production unsatisfactory. You’ll notice that with pruning and deadheading, your petunias will be more productive.

 

Question #2. When to trim petunias?

In general, you can pinch at planting time to help encourage growth, and pruning itself is feasible in the middle of summer. This way, you don’t remove any potential new blooms. But what is the difference between minor and drastic pruning?

Intensive pruning is necessary if you notice your plants having trouble blooming, especially during the growing season. On the other hand, minor pruning is an option for the gardener once the plant is established. You’ll gauge if your plants need pruning or pinching, whether it’s to help with flower production or to retain a compact shape.

Intensive pruning can be the removal of two-thirds from the leggy stems and repeating it after a week. You’ll check if the plant is producing new blooms after trimming and if it grows more stem and leaves. Some gardeners also cut back late in the growing season, but keep in mind to leave some new growth on the branches. 

 

Question #3. Why trim petunias?

Trimming petunias is a useful solution for plants that are being unproductive. More so, it helps in keeping petunias healthy and looking bushy. You will also need to deadhead some varieties because they can’t drop the faded flowers on their own. 

Most gardeners trim petunias as soon as they plant them to encourage blooming. It doesn’t have to be intensive yet, as removing some stems weekly is practical. Clipping half of at least four stems of new petunias will encourage flowering. 

 

Maintenance Tips For Petunias

Besides pruning and deadheading, another good practice to prevent petunias from being unproductive or developing leggy growth is keeping them well-watered. More so, the ideal environment for them plays a significant role in their overall health. This includes proper lighting, spacing, temperatures, and regular checkup for potential diseases.

For feeding, a balanced fertilizer would work well for petunias. Depending on the variety, your plants may want to feed weekly or use a time-release fertilizer. The main takeaway here is always checking the specific petunia variety or cultivar you have and adjusting your practices to its needs. 

 

Conclusion

With the many varieties of petunias, you’ll indeed find the perfect fit for your garden. But to keep them looking their best and stay healthy, you must learn how to trim petunias. The good news is there are no plant-specific practices for petunias. 

Some varieties can even clean themselves. However, cutting leggy and unproductive branches, removing faded flowers, and pinching is not just beneficial for aesthetics. They also help your plant produce more flowers and stay healthy. 

In general, you can pinch and prune petunias once a month. However, the emphasis is necessary for understanding the three questions first. Identify what to consider, when to trim, and why trim petunias to create the ideal trimming practice for your plants.

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.

 

Conclusion

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.
