How To Divide Black Eyed Susans In 3 Steps

If you’re interested to learn how to divide black eyed susans, you’ll be pleased that it only takes three steps. While these plants easily tolerate challenging conditions, it’s always advantageous to know how to divide them. You can use this technique not only for propagation but also for maintaining mature black-eyed susans. 

You can then transplant your black-eyed susans in the greenhouse if the outdoor conditions are too risky for growing newly divided plants. Remember that while division itself is easy, you want to guarantee the establishment of the sections. Therefore, it’s better to grow them in the greenhouse until the outdoor conditions are stable. 


How To Divide Black Eyed Susans In 3 Steps

Propagating Black-Eyed Susans By Division


Step #1. Preparation

The first step in dividing black-eyed susans is preparing the plant and site. Remember that it should be at its optimal health, and the site is ready for the divisions when separating any plant. You don’t want to make the plants wait for too long, or their roots will dry up. 

The plant itself should also be free of any diseases and damages. Therefore, you can consider the greenhouse not just for transplanting the divisions but also for growing the black-eyed susans for the division. After you have secured healthy parent plants, you can consider dividing them at the beginning of spring or fall when they are around three years old for maintenance and propagation. 

Water your plants thoroughly on the day you intend to divide them and prepare the site before digging them out. You can grow the divisions indoors or in the garden as long as the site is free of weeds and debris. Loosen the soil and make the necessary amendments, if any. 


Step #2. Digging and dividing

To make the lifting of your mature black-eyed susan more comfortable, trim its foliage so that it’s 6 inches from the ground. This will make it easier to see where to dig around and lift the plant without damaging its roots. Allocate a distance of six inches from the plant when digging and lift the entire clump. 

If you are dealing with an overgrown clump, you can divide and lift it per section. Otherwise, shake off the root system to get rid of the soil or hose it down to see the roots. Divide the clump so that each section has at least three shoots using a sterilized knife or by hand. 


Step #3. Transplanting

Once you have divided the plant into sections, you must plant them immediately to prevent the roots from drying out. You can grow them in the greenhouse or directly in the ground as long as they’ll be at the same depth they were growing. More so, be mindful that you’re not burying the divisions too deeply as this can be problematic for their establishment. 

Firm the plant into place and water them to help with faster recovery. If you’re not planting indoors, remember to mulch them as well to protect from the temperatures. You can then fertilize in spring when they develop new growth to boost the plants. 



Other Ways To Propagate Black-Eyed Susans

If you don’t have mature enough plants for division, you can propagate black-eyed susans from seeds and cuttings. The best time to plant your black-eyed susans, regardless of the propagation technique, would be in spring or at the beginning of fall. This way, you can assure that they have established their roots before the weather gets challenging. 

More so, the plants will benefit if you start in the greenhouse until they are vigorous enough for transplanting. Afterward, allow your plants to thrive somewhere with good water retention and full sun. Depending on the variety you’re growing, you will need to do additional practices such as staking. 



You can grow black-eyed susans from seeds without much hassle. You can get them from centers, but remember that this plant self-seeds readily, so you can just let them drop the seeds themselves after the flowering season. Otherwise, sow the seeds in the greenhouse before the temperatures warm up to make germination easier. 



You can also grow black-eyed susans from cuttings of a healthy plant. Take six-inch sections below a node and stick them in containers with moist soil. You can also root indoors to protect the cuttings from harsh weather as they are developing roots. 



Division is an excellent way to maintain mature black-eyed susans and also propagate new plants. It only takes three steps to learn how to divide black eyed susans, and the process itself is relatively straightforward. The best time to do this is in fall or the beginning of spring when your plants are around three years old. 

Cut back the plant to make it easier to dig around and lift it. You can also divide the clump if it is overgrown, then wash the roots to make sectioning easier. Each division should have about three shoots, and remember to plant them immediately to keep the roots from drying. 

Finally, water thoroughly and fertilize in spring when you notice new growth. If you can’t divide your plants yet, you can also consider growing black-eyed susans via seeds or cuttings. Start them indoors and then transplant somewhere with full sun for optimal health.

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.
