How To Grow Orchids In Water In 3 Easy Steps

Do you know that you can learn how to grow orchids in water by preparing the plant and container and maintaining the plant? These three easy steps are excellent for novice gardeners, and you can add the skill to your arsenal for gardening. Additionally, hydroponic orchid growing or water culture is a useful remedy if your orchid seems weak. 

You can unpot the orchid and examine its roots for issues. Afterward, you can grow it in water to address the problems while keeping the ideal conditions. If you have a greenhouse, you can do hydroponic orchid growing inside as well. 

Remember that this environment is optimal for the growth of orchids, that even if you dye them blue, they will stay healthy. Additionally, most orchids are epiphytes, so one can expect that they are a bit meticulous to where they would grow.

How To Grow Orchids In Water The Best Way

As mentioned earlier, most orchids are epiphytes and picky in their growing environment. For hydroponic growing of orchids, opt for terrestrial orchids. Why terrestrial orchids?

Generally, they thrive in moisture, making them ideal for hydroponic cultivation. Growing orchids in water will provide this requirement from soaking while still preventing rot and other potential problems. It’s also worth noting that not all hydroponic or water culture of orchids are the same. 

For example, some gardeners use a culture pot for the plant and an outer reservoir pot for the nutrient solution. This method improves the airflow around the roots, and you can quickly check when or when not to water the orchids. 


Prepare plant

The water culture of orchids requires preparation of the plant itself. Remove the orchid from its pot and make sure that it is free from the previous media. If the roots are tangled, be gentle in teasing them out. 

After the initial removal of media, rinse the roots and check for any rotten parts. Use sharp and sterilized pruners to cut them out. You might also benefit from using hydrogen peroxide or anti-fungal powder to ensure the cleanliness of its roots.

This initial preparation is crucial because root rot will affect the success of your hydroponic orchids. Once you’re happy with the resulting plant, you can place it in the new container. However, ensure that it is big enough to accommodate the growth of the roots. 


Prepare container

What is the best container for growing orchids in water? Most experienced gardeners would recommend something with high curved sides that is also transparent for more comfortable viewing of growth and dirt. The container also stabilizes the plant and prevents it from flopping over as it grows. 

Speaking of supporting the plant, you want the orchid to stay upright. Use some clay pebbles at the bottom of the container to help the roots. As a bonus, this also prevents the rotting of the crown since it is off the moisture. 

Once you have the container, the next material to check is the water. Tap water is not advisable because some areas have contaminated sources with chemicals. Of course, these chemicals can be detrimental to orchids. 

The safe choice is using distilled or, better yet, rainwater. Before planting, make sure that it is lukewarm as well to prevent shock. 



Remember to change your water weekly or bi-weekly so that it is free of any contaminants or pathogens. This also makes an excellent time to fertilize the orchids. Otherwise, it can be feasible to soak the orchid for two days and then dry for five days if this will help with its growth. 

Using airstone can also help supply the orchid’s optimal oxygen requirements if you see signs of oxygen depletion. What about the other provisions of orchids? Using a greenhouse will not only encourage growth but also blooming of the orchids grown in water. 

For example, the temperature is easier to manage indoors, and you can conveniently place the grow light at the ideal distance from the orchids. As the University of Vermont Extension mentioned, these factors are influential to the growth of orchids. Check the specific requirements of your orchids and adjust the environment accordingly. 


What Is Passive Hydroponics For Orchids?

When growing orchids in water, you might also come across the passive hydroponics method. This process includes adding nutrients to the water, and the capillary system will bring it to the roots. Additionally, passive hydroponics uses perlite, gravel, clay pebbles, or charcoal to act as an inert and wicking medium. 

When the reservoir is low, you’ll flush the substrate with lukewarm water, so the air pockets deliver oxygen to the orchids. To further help with wicking moisture to the roots, the orchids’ container has side drainage holes and the reservoir at the bottom. 



Orchids are beautiful flowers, and they grow in a variety of mediums. If you want to skip soil, you can learn how to grow orchids in water in three steps. Prepare the plant, container, and ensure maintenance throughout the growth of the orchids.

It would be best if you also remember to use terrestrial orchids as they are more suitable for water culture. They thrive in moist conditions and will grow well in water compared to epiphytic orchids. The overall method of growing orchids in water is easy even for beginners, and you can also learn about the other techniques, be it using two pots or growing passively.

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.
