How to Propagate Dendrobium Orchids from Cuttings

Perhaps you’re wondering how to propagate dendrobium orchids from cuttings? Dendrobium orchids have more than 1,200 genera found globally. They are further classified into two types: deciduous and evergreen plants. Both have their differences, but you can successfully grow both types in a greenhouse.

If you’re new to planting orchids, it’s better to choose the deciduous type because they’re more resilient than evergreens. Evergreens are also a great option if you plant them inside a greenhouse because they’re easy to grow as long as you get the indoor climate right.

Generally, dendrobiums need minimum light requirements, but you need to water them more frequently. As they are growing, place them under partially shaded areas where they can get enough sunlight during certain times during the day.


How to Propagate Dendrobium from Cuttings

If you want to propagate dendrobium orchids from cuttings, here’s how:


Step #1: Cut the Spikes

Dendrobium produces flowers on the short spikes that grow from the nodes found on the stem. Cut the spikes once the flowers fall, but make sure to dip your shears in rubbing alcohol between each cut to avoid spreading possible infections.


Step #2: Cut the Stems

When the flowers have died back, pick the stems that are about a foot long. Remove them from the parent plant and cut them into sections with at least three nodes in each.


Step #3: Prepare the Rooting Tray

Get a rooting tray and add a layer of pebbles and choose from a sphagnum moss base or bark. If you decide on moss, make sure to soak the moss in water until it’s soaking wet. Drain the water from the moss and spread it evenly on the rooting tray. Place the orchid cuttings on top of the moss and spray it with water. Keep your plants humid by covering them with a plastic wrap and place the rooting tray in a warm location away from sunlight.


Step #4: Care for the Cuttings

To ensure that your orchids are propagating well, the room temperature should be around 75 to 85 degrees F. Spray the orchid cuttings with water to keep them moist at all times but not soaking wet. For the first two months, spray your cuttings with water-soluble nitrogen fertilizer every two weeks until you can see leaves and roots sprout from the cuttings. Make sure to follow it up with a light spray of water. Remove anything that shows rotting.


Step #5: Potting

Once you see shoots and roots, cut the stem between the sprouts using sterilized shears. Transfer them to pots where they can grow. Dendrobium orchids grow best in small flowerpots. Place them in two-inch pots using a planting medium of weathered volcanic rock, bark, or sphagnum moss. No matter which medium you choose, soak it in water until moist. 

Plant the cuttings and make sure the old stem is erect, and the shoots are facing sideways or upwards. You can add a stick for support if necessary, so it remains upright. New leaves will eventually sprout, and the roots will grow into the medium.


Why Grow Your Plants in a Hobby Greenhouse?

To ensure that your orchids will grow healthy, you can place them inside a hobby greenhouse. There are many reasons why gardeners invest in a greenhouse, such as:


Keep plants away from harmful pests

If you’ve been growing orchids for quite some time, you’d know that they are susceptible to insects, such as thrips, scales, aphids, mealybugs, and two-spotted spider mites. Keeping them in an enclosed space prevents these pests from munching on your orchids. Additionally, plants inside a greenhouse are safe from infectious diseases that may be affecting garden plants.


It comes in different sizes

When people think of greenhouses, they automatically think of large, glass-walled greenhouses. However, greenhouses come in different shapes and sizes – from greenhouses, you can place on tabletops to greenhouses as big as a barn. Unless you’re a prominent plant grower, gardeners generally use mini-greenhouses.


Great for people with small garden spaces

If you want to grow different crops, but you only have limited garden space, a mini greenhouse is a perfect solution to small spaces. With a standard size of six feet, you can place a mini greenhouse on balconies, decks, and patios. There are smaller options as well if you want a more compact gardening solution. Even though these greenhouses are relatively smaller than usual, you’ll get the same benefits.


Start planting early

A greenhouse allows gardeners to start plant growth even before the planting season begins in your area. Regardless of the weather, your plants will thrive inside the greenhouse. Once the weather warms, you can transplant them into your garden if you want to.


Protect your plants from bad weather

Bad weather can instantly damage your months’ worth of hard work. A greenhouse is also useful in keeping your plants safe from inclement weather, such as storms, high winds, frost, snow, and more. You can place them in a greenhouse where they can grow and thrive.


Final Thoughts on How to Propagate Dendrobium Orchids from Cuttings

You need to know how to propagate dendrobium orchids from cuttings if you want to grow beautiful orchids. With these tips in mind, you’ll enjoy plentiful blooms at any time of the year.

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.
