How To Propagate Dianthus. 3 Best Ways

You have three options if you’re interested in learning how to propagate dianthus. This gorgeous flowering plant offers many varieties, including annuals, biennials, and perennials of different colors. And because you have three methods to propagate dianthus, every gardener can choose what they think is convenient for their circumstances. 

Dianthus is relatively easy to propagate and grow that they will even thrive well in pots. However, it’s worth noting that propagation means you’re starting from young plants, so their starting environment should be stable and optimal. Whether you’re sowing seeds or planting cuttings and division, consider rooting dianthus in the greenhouse until your outdoor environment is stable. 


How To Propagate Dianthus. 3 Best Ways

How To Propagate Dianthus Comprehensive Guide


Option #1. Seeds

Dianthus have capsule-like fruits, and you can collect them for seeds, but be careful in handling them because they get damaged easily. You can store the seeds in a sealed container that blocks light and then place it somewhere cool and dark. 

Sowing dianthus seeds is relatively safe and straightforward, especially when you start indoors at six weeks before frost. Fill a starter tray with a mix of potting soil, peat moss, compost, and sand. Make sure that this medium is moist and cover the seeds lightly after sowing. 

Place the trays somewhere bright but out of direct sunlight, and dianthus should germinate after ten days or less. However, they must be away from drafts and other extreme conditions. You can then transplant the seedlings when they reach around 4 inches in height. 


Option #2. Cuttings

Propagating dianthus from either cuttings or divisions is a sure way to create clones of your favorite plants. You can ensure that the young plants will be right to your parent plant’s characteristics, unlike seeds. However, make sure that the parent plant you’ll use is healthy so that it won’t get stressed after you take cuttings. 

When is the best time to take dianthus cuttings? The best time to do so is on a cloudy day sometime in June or July after the plants finished flowering. You can also prepare your parent plant by watering it well before you plan on taking a cutting. 

Select a healthy cutting with leaf nodes and dip its end in a rooting hormone powder. You can use a starter pot with a mix of vermiculite and sand, then make sure that the stem is well-supported after you inserted it. Maintain moisture and cover with plastic, then place it somewhere bright until transplanting when it grows new leaves. 


Option #3. Division

The final propagation method for dianthus is from division, and this is best for the perennial varieties of the plant. More so, the division is also part of maintenance as your dianthus plant matures, and you can do this in early spring while it’s actively growing. You can divide a mature plant every three years, which is an excellent way to produce more plants from a variety you love. 

To divide dianthus:

  1. Dig around the plant so you can lift the root ball comfortably without damaging it
  2. Remove the soil around the roots to make sectioning easier, and you should get around three pieces of section
  3. Throw away the dead portions and make sure to transplant the sections as soon as possible

For planting, use the same depth of where they are growing as measurement and support each division by pressing the soil around its roots. Much like with seeds and cuttings, you want to maintain moisture for the plant’s establishment. To prevent the divisions from drying, prepare the medium beforehand using moist potting soil or the same material it’s from if you’re planting in the garden. 


Caring For Dianthus

After propagation, you should also learn how to care for dianthus to ensure that they stay healthy and resilient against environmental challenges. In general, they are not meticulous when it comes to location. This is why after establishment, you can select an area with fertile and well-draining soil either under full sun or partial shade

Perhaps the most common mistake when caring for dianthus is overwatering. Much like other flowering plants, it’s best to only water dianthus when the medium is dry. You can also feed them every six weeks or use a slow-release fertilizer according to the label. 

Nonetheless, it would be best to know the specific needs of the dianthus variety you have. For example, some dianthus plants require deadheading because they are self-sowing. On the other hand, some types may not require additional maintenance practices. 



Dianthus is one of the most diverse flowering plants that you can get for the garden. Therefore, knowing how to propagate dianthus will give you the flexibility to create more of this gorgeous plant, regardless of the variety you have. You’ll be pleased to know that dianthus can root either from roots, cuttings, and division, so you have more options to choose from. 

With seeds, you can avoid the challenges of the climate by sowing indoors. You don’t need to do any pre-germination treatment, and dianthus should root within a week. On the other hand, using cuttings or division is a useful method for those with existing adult plants. 

With a healthy dianthus parent plant, you can take cuttings and root them directly. Those who have dianthus plants around three years old can also take sections and grow new plants. In general, dianthus doesn’t have many requirements to establish itself as long as you start in an ideal environment like the greenhouse before transplanting.

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.
