How To Propagate Coreopsis. 3 Best Ways

Do you know how to propagate coreopsis using seeds, cuttings, and divisions? Generally speaking, coreopsis is low-maintenance plants, and propagating them is incredibly beginner-friendly. You can even feel more confident in rooting them if you use a greenhouse to start seeds or cultivate parent plants for cuttings and divisions. 

Coreopsis or tickseed is Florida’s state wildflower that thrives in hardiness zones 3 to 9. This gives you an idea of the flowers’ ideal growing conditions, but the greenhouse should save you from getting worried about your vulnerable propagations. While coreopsis is hardy, remember that all plants at the beginning of propagation are still at risk with damages, so choose the best location and follow the methods below diligently. 

How To Propagate Coreopsis. 3 Best Ways

How To Propagate Coreopsis Correctly


#1. Rooting coreopsis from seeds

It’s not surprising that Cornell University recommends starting coreopsis seeds indoors instead of directly sowing them in the garden. Seeds are sensitive to fluctuating temperatures and weather, so it’s wise to start them in an environment you can control, such as a greenhouse. Afterward, you can move the more vigorous plants outdoors by checking your last frost date as per the area’s hardiness zone

Where can you get coreopsis seeds? You can buy them, but you can collect them from your existing tickseeds. Check the dead blooms, pinch them off from your plants, then store in a cool, dark, and dry place to get the seeds inside easier later on. You can then collect the seeds from the dried blooms when they rattle inside. 

The ideal time to sow indoors is in late winter, but Cornell University mentioned mid-spring is fine outdoors if you have no greenhouse. Just find a location that receives full sun with moist soil, and the seeds should take two weeks to germinate depending on the variety. Afterward, plant your coreopsis 12 inches apart, and they’ll bloom at around two months. 

For the greenhouse, you can use a seed tray with potting compost and then keep it moist. Place it where it won’t receive direct sunlight, and adjust the temperatures and humidity indoors. The seeds should sprout at six to eight weeks. 


#2. Rooting coreopsis from cuttings

If you have expensive or named coreopsis cultivars, then you know that vegetative propagation is preferable than using seeds. This is because you can’t assume what blooms you’ll get when you propagate from seeds, and if you want to preserve the true identity of a cultivar, cuttings and divisions would be the sensible choices. When rooting coreopsis from cuttings, you can take them from the parent plant in spring. 

Remember that regardless of what you’re propagating, the parent plant should be healthy and embody the characteristics you want to clone. This is where using a greenhouse is advantageous because you can ensure that you’ll have healthy coreopsis plants for taking the cuttings. Once you have your eye on a plant, make a 4-inch cutting at a node with a sharp and sterilized knife at a 45-degree angle. 

You want to keep the cutting bare and only keep some leaves toward the top. Dip it in a rooting hormone to help with growth and use a pot with moist and fertile soil. The pot should be in direct sunlight at temperatures around 65°F, and the cuttings should have rooted themselves by two weeks, ready for replanting. 


#3. Rooting coreopsis from divisions

If you want to get actual plants from your cultivars and hybrids, rooting them from divisions is a sure method to clone them. The University of Vermont recommends doing so in spring when you notice new growth on your coreopsis plants. You can also divide your plants consistently in early spring or even fall every 2 to 3 years, which will benefit your coreopsis in the long run. 

Be gentle in digging up your plants and then shake off the soil from the clumps. Divide the crown into sections so you’ll have new ones with roots. You can then plant these sections in the same growing environment as the parent plant, but remember to keep the divisions well-watered for weeks until they establish themselves. 


Maintenance And Care Of Coreopsis

Most university extensions praise coreopsis for being resistant against most pests and diseases. Therefore, you don’t need to do unique practices when caring for and maintaining them. You can, however, prolong your blooms by deadheading, which will also prevent reseeding. 

One can say that coreopsis requires deadheading as a non-negotiable task because it will ensure that the new growth will be healthy. Gardeners who want fall bloom should cut back late in summer and then let those bloom in fall be before cutting back again in early spring. You can also keep the seeds at the end of the flowering season for feeding birds.



You don’t need to live in Florida to cultivate the state’s wildflower. Learning how to propagate coreopsis is easy, even for a novice. You can root tickseeds from seeds, cuttings, and divisions, and all methods are quick and straightforward.

The best environment for propagation would be in a greenhouse because it’s suitable for starting vulnerable seeds or growing parent plants for cuttings and divisions. Like all plants, newly propagated plants are still establishing themselves, so you must get them vigorous enough for transplanting in fluctuating outdoor conditions.

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.
