How To Root Begonia. 2 Best Ways

Those who need to learn how to root begonia can choose from two methods. This diverse group of flowering plants can root either in water and soil. This is why even newbie gardeners shouldn’t feel intimidated in starting begonia plants themselves.

If you think starting begonias from seeds is too meticulous, you can use cuttings from your favorite mature plants instead. These cuttings should root quickly, but more so if the environment is stable. This article will guide you on rooting begonias without drawbacks. 


How To Root Begonia. 2 Best Ways

Comprehensive Guide On How To Grow Begonia

Before anything else, it’s worth noting that you have many propagation methods to choose from in starting begonias. They include division and cuttings, but using the latter is more advantageous. One can say that rooting begonias from cuttings is easier and more straightforward compared to other techniques.


In water

In general, rooting begonia cuttings is already easier compared to most plants because they develop roots quickly. One way to do so is to grow them in the water, which is the best technique to do if you are a beginner gardener. What makes begonias even better for rooting in water is that you can use this method to grow healthy plants from leggy stems. 


Step #1. Taking the cutting 

Choose a mature begonia plant, and you can take sections of its stems for rooting. As for maintenance, you can even remove the leggy stems from the plant and use them for propagation. Take stems around four inches long below the node using sharp and sterile scissors for a clean cut and to prevent disease transmission.


Step #2. Preparation and submersion

Before placing the cutting in water, you want to prepare it first to ensure root development. Much like when propagating other stem cuttings, remove all the leaves except some at the top. This way, they won’t get wet and rot when you place the cutting in water. 

You also want to remove all the flowers, so the begonia focuses its energy on growing roots. Remember that if the cutting still has flowers, it can encourage seed development instead. Once the cutting is ready, place it in a glass with water, and you can expect roots after a month. 


In soil

A more traditional way of rooting begonias is in soil. Perhaps growing cuttings in water is more desirable if you want to transplant leggy stem sections later on. Otherwise, rooting begonias in the soil might be the better choice if you have specific varieties that you want to propagate. 


Step #1. Taking the cutting

Similar to rooting begonias in water, you want to take 4-inch cuttings from a healthy parent plant. You can use a pot with moist vermiculite and then let the water drain thoroughly from the medium before planting. Stick the cutting in the container and ensure that it stands upright. 


Step #2. Maintenance

You can cover the pot with a plastic bag to maintain a humid environment to encourage root development faster. Place the containers somewhere bright and warm, and you can expect roots after a month or less. If your region has fluctuating temperatures, you can consider placing the cuttings in the greenhouse until they are ready for transplanting. 



Transplanting Rooted Begonias

Whichever method you chose for rooting begonias, remember only to start transplanting them when they have matured enough. This means only planting them when the roots are around two inches long to guarantee that they can establish themselves. If you rooted begonias in water, you should feel confident that they can stay there for some time if necessary. 

Where should you transplant begonias? A pot with moist potting soil is ideal, but make sure that it is large enough to anticipate the roots. Set the cutting in the container so that its root base is an inch below the rim.

Water the transplant and let it drain from the pot before placing the cuttings somewhere bright to encourage establishment. You can also prune new growth when you notice them encourage a bushier begonia. More so, be mindful of your watering practices are begonias are susceptible to root rot. 


Caring For Begonias

To ensure that your begonias will thrive, place them somewhere humid and warm, around 65 to 72°F. They should also receive morning sun to bloom well. When it comes to feeding and watering, you can fertilize once a month and maintain the soil moist. 

Remember that one of the common problems that can damage begonias is overwatering, so always check the medium before watering. Should you prune begonias? Overall, you can deadhead the plant to help extend its blooms and create healthier flowers. 



Those who have mature begonia plants have the option to propagate more plants from cuttings. You can quickly learn how to root begonia either in water or soil, and you can expect root development in a month or less. But whichever technique you choose, you may find it easier to grow begonias in the greenhouse to protect them from fluctuating conditions. 

A four-inch section should suffice for rooting. Remove the bottom leaves to prevent rot, and make sure to trim any flowers as well to help the plant focus its energy on rooting. Set the cutting either in water or soil, and they should be ready for transplanting when the roots are two inches long.

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.
