How to Grow Hardy Hibiscus from Seed

Are you looking to find out how to grow hardy hibiscus from seed? Hardy hibiscus (Hibiscus moscheutos), also known as swamp rose mallow, are naturally found in swamps, marshes, or in moist areas nearly around rivers and ponds. These plants grow from at least two feet tall up to a maximum of ten feet tall, with flowers that are four inches to ten inches wide.

The Hibiscus genus belongs to the mallow family (Malvaceae) and it contains several varieties of shrubs, plants, and trees. These plants originated in tropical climates, but they can survive when planted indoors and in containers as well. Many gardeners grow hardy hibiscus because of the beautiful flowers they produce, while others plant them because of the fiber they produce that could be used to make clothing.


How to Grow Hardy Hibiscus from Seed


Hardy hibiscus seeds take a long time to germinate, so you may need to take the seeds indoors or in a greenhouse for about two to three months before frost occurs. To speed up the germination process, you can use a sharp knife to nick the round end of the seed coating, allowing moisture to enter. Soak the hardy hibiscus seeds for about eight hours in lukewarm water.


Planting/Transferring of germinated seeds

After the germination process, the next step is to plant the seeds into a tray, small containers, or straight into a garden bed. Choose a potting soil or seed-starter mix for your hardy hibiscus seeds. Plant the germinated seeds for about a quarter-inch deep in your seed-starting mix or potting mix, keep it warm, and in sunny conditions – at least 75 to 85 degrees Fahrenheit.

If all goes well, your planted germinated seed will sprout after two to three weeks. If you planed your hardy hibiscus plants indoors, you will need to place them into medium size pots to manage and accommodate their growing size. Young hardy hibiscus plants are extremely fragile particularly in their stems, so you must be careful in moving them outdoors; yard, bed, big pots. Do not plant them outdoors unless they are strong enough to survive in adverse temperatures.


Last Frost Date

After the danger of frost has passed you may start to harden-off your hardy hibiscus seedlings that have already grown. You can take them outside to acclimate for a few hours a day. Keep in mind that hibiscus plants naturally grow in swampy and moist areas. This means you’ll need to create a climate similar to warm, swampy areas.


Find a Fixed Area to Plant Them In

Hibiscus plants can grow up to ten feet tall, so you need to set an area where you can plant permanently your growing hardy hibiscus flower. Transferring the hardy hibiscus seedlings must be handled carefully.

Dig a hole in your fixed area where you want to transfer your hardy hibiscus flower, loosen the soil up to one foot deep. Set your hardy hibiscus inside the hole with soil then temporarily stop for a while at the halfway point. You must avoid placing any soil on top of the root ball to prevent suffocating the plant that will cause damage and failure to grow.


Water Your Plants

When your hardy hibiscus flower plants are transplanted properly, it’s important to water them carefully. Since hardy hibiscus naturally grows in watery or moist areas, you should make sure that it will not get bone dry. The soil should remain moist at all times, but not wet to avoid root rot.


Tips on How to Take Care of Hardy Hibiscus Plants

Like other flower plants, particularly perennials, you must have at least a few minutes every day to check on your hardy hibiscus plants. They grow healthier when carefully maintained. At least having mere time taking care of your plant, in return, expected bloom and produce are assured.

Considering the weather conditions of planting such as perennial type plants, will help you to have a lesser tendency of failed growth. Frost dates are dangerous to this type of plant and taking note of it is necessary to have a proper dated schedule in planting plants like this.

It’s important to regularly examine your plants for pests. Most pests are too small, so you’ll need to really get in there to be able to see harmful insects that are attacking your plants. Also, look for symptoms of diseases that can affect your plant. If not mitigated as soon as possible, your plant may not be able to survive for long.


The Benefits of Growing Hardy Hibiscus in a Greenhouse

There are several reasons why you need to consider growing hardy hibiscus inside a hobby greenhouse. For one, greenhouses protect your plants from pests and diseases that want to eat and damage your hardy hibiscus. It also protects your plants from the effects of unpredictable weather. Snow, heavy rain, storms, and high winds can easily damage a month’s worth of hard work. A greenhouse shields them from bad weather conditions so they can keep growing and producing more flowers.


Final Thoughts on How to Grow Hardy Hibiscus from Seed

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.
