How to Prevent Root Rot – Causes, Prevention, and Control

Are you wondering how to prevent root rot? Root rot is one of the most common diseases that can affect almost every plant. It happens when your plant’s roots are affected by pathogens that can cause rotting. The roots will turn into mush and they’ll be unable to transport nutrients throughout the entire plant. If you can’t control the problem, root rot can be fatal.


How to Prevent Root Rot – Causes, Prevention, and Control

What Causes Root Rot?

Root rot can be caused by different types of fungi, viruses, oomycetes, and bacteria. There are two main reasons why this disease happens: poorly drained soil and overwatering. These bacteria thrive in wet conditions. Wet soil prevents oxygen from getting into the roots. Oxygen-deprived roots will die and the rot can spread to other unaffected roots.

Weak roots are more vulnerable to soil fungus, which also causes root rot. The fungus can be dormant in the soil but when the ground becomes soggy, they can come back to life and cause root rot.


How Can You Prevent Root Rot?

When it comes to root rot, prevention is always better than cure. Fortunately, it’s easy to avoid this problem. You just have to make sure that you properly water and drain your plants. Here are some of the tips you need to remember:


Tip #1. Water on a regular basis

One of the ways to keep root rot at bay is to water on a regular basis. Otherwise, your plants will not have enough time to dry between every watering, which leads to root rot.


Tip #2. Ensure proper drainage

If you choose to grow your plants in a container, make sure that it has enough drainage holes. In this way, the water will drain out from the pot completely. If water stays too long, it’s going to cause significant problems, including root rot.


Tip #3. Examine the soil

Be sure to examine the soil before you water the plants. The watering schedule depends on the type of plant you’re growing. Some plants prefer to dry out before they need to be watered again, while others like to be kept moist all the time.


Tip #4. Keep the soil aerated

Make sure there’s enough oxygen in the soil for the roots to grow. It also ensures that there’s enough space for water and oxygen to flow. Additionally, aerated soil prevents moisture from building up in the roots.



How Can You Fix Root Rot?

If your plants have been infected and you’ve spotted the problem early, you can still save it if you act fast. Here are some of the steps you can take to control the root rot:


Step #1. Pinpoint the issue

One of the signs of root rot is when your leaves start to yellow and turn to mush. Uproot the plant from the container so you can check the roots. If they’re soft, wet, darker than usual, or mushy, you’ll need to treat the roots as soon as possible.


Step #2. Wash the roots

Take the plants out of the pot and carefully remove the soil around it. Remove the affected roots with gardening scissors. Clean the healthy roots by placing it under running water to clean the roots of any pathogens.


Step #3. Repot the plant

Transfer your plant in another pot with enough drainage and fresh soil. If you’re planning to use the same container, make sure to clean them completely. To be safe, it’s better to use a new pot. If the root rot was serious and you had to remove most of the roots, you can prune your plants so the roots expend less energy.


Step #4. Place them in a sunny spot

Once you’ve cleaned the roots and repotted the plant, you can return to watering it and fertilizing it regularly. Your plant should grow and become a new and healthy plant.


Why You Should Grow Your Plants in a Semipro Greenhouse

Growing your plants in a greenhouse is one of the best investments every gardener should make. Here are some of the reasons why you need one:


Prevent root rot

With a greenhouse, you can control the indoor climate by reducing humidity levels when you need to. You can also heat the air and venting the warm air out of the greenhouse. In this way, your plants will use up the water much faster, preventing the plant stress and pathogens from developing.


Keep your plants safe from pests

Aphids, beetles, snails, rodents, and other animals and insects can harm your plants. You can keep them safe and healthy by keeping them inside a greenhouse. This reduces the risk of insects munching on your leaves and produce. It also lowers the risk of contracting infectious diseases that may be affecting neighboring plants.


Protect your plants from inclement weather

Bad weather can wipe your garden in an instant. Heavy rain, high winds, frost, and excess heat can easily damage your plants. A greenhouse protects them from inclement weather, keeping them safe and healthy inside the enclosure. Once the weather warms, you can transplant them into your garden if you want to.


Final Thoughts on How to Prevent Root Rot

Now that you know how to prevent root rot, it’s essential to check your plants for signs of the diseases regularly. Avoid root rot by planting them in well-draining pots and soil.

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.
