How To Propagate Oleander. 2 Best Methods

If you want to know how to propagate oleander, you can choose between two methods. One shouldn’t feel intimidated in starting oleander plants themselves because they should germinate or root readily. You can also grow in the greenhouse to ensure the faster establishment of vigorous transplants. 

Even though oleander itself is easy to care for, you still want to create the ideal growing environment for the seeds or cuttings. This will ensure germination or root development compared to starting them outdoors with challenging climates. Once you have the seedlings or rooted cuttings, you should be ready to transplant oleander outdoors.


How To Propagate Oleander. 2 Best Methods

How To Grow Oleander


Method #1. Seeds


Seed collection and preparation

You can make use of your oleander plants after the blooming period and collect seedpods. However, the emphasis is necessary on wearing gloves and handling the plants correctly when you gather the pods because the plant can be toxic and irritating. And once you have the seedpods, let them dry up to split open on their own. 

You should end up with fluffy-looking seeds, which you have to rub against a screen to get rid of the feather-like parts. This is a faster way to collect the seeds, but you can also pick the fluffy parts yourself. Once you have removed the feather-like parts, you should be ready to sow oleander seeds.


Sowing and germination

The best way to guarantee success in growing oleander from seeds is by starting them indoors. Remember that temperatures below freezing will damage the seeds, so those in regions with true winters are better off sowing in the greenhouse instead. Once the danger of frost has passed, you can transplant your seedlings or start the seeds in the garden.

To start oleander seeds, use a seed tray with moist peat and then press them on the surface. You don’t need to cover the seeds with soil, but you want a humid environment to encourage germination. You can achieve this by covering the container with plastic wrap and maintaining the greenhouse temperature around 68°F. 

It would also be advantageous to use grow lights to help the seeds further. At this point, your maintenance would be spraying the medium to keep it moist, and your seeds should sprout after a month. You can then remove the plastic cover and transplant them outdoors once your oleander plants have grown true leaves.


Method #2. Cuttings


Cutting collection and preparation

If you want a quicker way to ensure copies of your favorite oleander plants, you can propagate them from cuttings instead of seeds. Select a healthy oleander plant and take new growth tips any time during the growing season for faster rooting. However, some gardeners also take cuttings in fall, but instead of green growth, you’ll be getting semi-woody ones, which will root slower than green wood.

Take a 6-inch section below a leaf node, but don’t forget to wear gloves when handling your plants. Prepare the cutting for rooting by removing the lower leaves to ensure that they won’t contact the soil and cause rot. You can also dip the end in rooting hormone before planting for faster root development.



Stick the cutting in moist potting mix and then place the container in a heat mat. It’s also advantageous to have them in the greenhouse to guarantee stable conditions ideal for rooting. And to create a humid environment, cover the pot with clear plastic and regularly check the medium’s moisture until the cuttings develop roots.

You should be ready to transplant outdoors in the fall if you used greenwood cuttings. On the other hand, semi-woody cuttings would make ideal transplants in spring. These timings are crucial so that you’re confident that the oleanders have already established themselves to survive the outdoor conditions.



Growing And Caring For Oleander


The most important consideration

As discussed earlier, it’s crucial to wear protective clothing when handling oleander plants. Wear gloves and long sleeves to avoid direct skin contact. Remember that these plants are poisonous and irritating that even burning their debris is dangerous since inhaling the resulting smoke is toxic. 

Be mindful of pets and children as well because ingesting any plant of the part is also fatal.



The ideal location for growing oleander is somewhere with full sun and in neutral, fertile, and well-draining soil. Besides propagation, the greenhouse is also excellent for maintaining oleander plants because it will protect them from challenging climates. After all, frost will damage the plants.



Oleander plants can tolerate drought, but if you want eye-catching blooms, you want to keep them well-watered. You can also feed them with balanced fertilizer occasionally for additional boosts. Finally, like most shrubs, oleanders will benefit from pruning, especially when you see many damaged parts or if the plants are overgrowing the area.



With proper safety in handling, one shouldn’t be intimidated in working with oleander plants. You have two methods to choose from to learn how to propagate oleander. They are sowing seeds and rooting cuttings.

You can do either technique in the greenhouse so that the conditions are stable. This should guarantee germination or root development, which should help you get established transplants. Afterward, maintaining oleander is smooth sailing.

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.
