How To Get Rid Of Thrips On Roses: 3 Easy Steps


Step #1. Inspect roses

The first step to eradicate thrips is to inspect your roses. The control of pests is more effective if prevention always stays in your management practices. And once you notice where they are prevalent, you can make the next move, eradicating. 

What are the signs of thrips infestation on roses? Distorted leaves, swollen blossoms, and discolored petals are all indications that thrips are present on the roses. According to the University of Maryland, thrips are active in June, so always check your roses this season. 

You can use sticky cards above the roses to confirm your suspicion. They should effectively trap adult thrips since it’s tricky to see these tiny insects. In the greenhouse, ensure that you also maintain cleanliness such as weed removal because thrips can hide in them


Step #2. Isolate and remove thrip damage

The most common way to control thrips is by merely removing infected plants and pruning the damaged parts. The plants themselves can stay in another area, isolated from the other plants, to prevent pests’ spread. This will help you slow down their activity and lower the population as you treat the infected roses. 

It would also be best to remove thrip damage on leaves, stems, and blossoms and keep them together in a sealed plastic bag. It’s highly likely that these portions have nymphs and adult thrips, so it’s best to do this as soon as you suspect thrip infestation. However, don’t forget to practice proper sanitation, especially with the pruning shears and other materials to not bring thrips on other roses. 


Step #3. Treat with insecticide

After thrip removal comes to the final step, which is treating the roses with insecticide. The greenhouse makes a suitable environment for treating plants with pests because it’s easier to apply the pesticides and target the infected parts. Still, it’s worth emphasizing the need to read the insecticide label first for you and your plant’s safety.

Many gardeners often frown at the idea of using an insecticide, but sometimes, the number of thrips get very high and hard to control. After all, using an insecticide early on means it can eradicate the thrips soon, and you can stop using chemicals much early too. And if you think about it, thrips cause damage at such a short period that using insecticides is undoubtedly the lesser evil of the two. 

A systemic insecticide should work well for treating thrips on roses. You can sprinkle half a cup of it over the soil where the rosebushes are to kill the pupas on the ground. This way, you can prevent the addition of adult thrips in the days to come. 

After the soil, use the insecticide on the rosebushes until the product covers the plant entirely. This is crucial to ensure that the insecticide comes in contact with all the thrips. You can then apply insecticide once a week throughout the growing season in case some thrips survive. 



Controlling And Preventing Thrips On Roses

The key to pest management is always to aim to prevent having them in the first place. For example, you can grow your roses in the greenhouse to create a more controlled environment. Then, maintain cleanliness and sanitation to prevent the introduction and spread of thrips. 

If you remember, step number one pertains to the inspection of roses. This is a necessary practice not only when you suspect thrips, but even as a preventative measure altogether. Make it a habit each week to check your roses, not just on thrip season. 

Regular inspection will put you ahead of the thrips and control them faster. Perhaps the simple removal and pruning of infested roses would be enough, and you don’t have to use chemicals. More so, pruning regularly will help prevent thrips and is not only useful for eradication. 

You can also consider adding predatory mites in the greenhouse that can feed on thrips in the early stages. If the infection is not that severe, but you see thrip damage, neem oil makes an excellent solution before immediately trying insecticides. 



Even roses are not safe against pests. If you notice discolored petals, distorted leaves, and swollen blossoms, you might need to learn how to get rid of thrips on roses as soon as possible. Start by inspecting the roses and removing thrip damage. 

The greenhouse makes these steps easier because of space, but make sure to have another area for isolating infected plants. Depending on the severity, you might get away with pruning away the infected parts, using neem oil, or adding predatory insects. However, systemic insecticide would be the best choice if the population is hard to control.

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.
