How Do Poinsettias Change Color

Why and how do poinsettias change color? It’s important to note that regardless of the cultivar, there is one trait all Christmas Stars share, which is the fading of hues.

While you would usually see the poinsettias in red, they actually come in different colors, and the tinted parts are, in fact, leaves or bracts, not flowers. They are desired by many as they are perfect for getting the vibe of the Christmas season.

Unfortunately, poinsettias are not fated to live long. Even if you somehow get to extend their lifespan, their vibrant tint is bound to lighten nonetheless. However, you don’t need to worry because there is a way to bring that pop of color back.

 

How Do Poinsettias Change Color

What Affects the Color of Poinsettias?

Although the fading of the colors of poinsettia leaves is nothing unusual, the process is not natural. Certain agents can influence the pace at how these plants change their color, and to some extent, these are controllable.

To fully grasp the science behind the gradual shifting of their colors, you have to know about photoperiodism. In simple terms, it pertains to the reaction of the plants when exposed or otherwise concealed from sources of illumination.

When there is not enough light, the leaves that are supposed to be tinted in green turn into red instead. However, there are also instances that the shades are lighter, like pink or white, for example.

 

How to use light to manipulate poinsettia’s color

If there’s exposure to light, then it can make the bracts of poinsettias green, although you might think turning them back to red may be as simple as denying them that illumination. However, that is not the case. Without light, your plants would not be able to absorb energy and will wither.

Since the formation of that pop of color you desire is encouraged by darkness, the plants still need light, so you balance both. During mornings, give them as much as they need, but completely conceal them during the night.

If you think letting them be would be fine as the sun would not be able to reach your plants in the evening, then you are wrong. Even artificial light can disrupt the process, so you have to hide them in total darkness and even cover them if needed.

Without missing one day, your poinsettias should be detached from any form of light for at least 12 to 14 hours. Remember, skipping once can render all your efforts useless. Start this routine two months before you intend to display the plants elsewhere.

 

How to turn poinsettia’s color back

Aside from the technique involving light, there are other things that you can do to bring vibrance back to your poinsettia plants. One of which is pruning. If you want to give the new growths the chance to showcase their colors, then remove the faded ones.

After doing so, you can transplant them in a pot that is appropriate for its size, or do this as soon as they outgrow their previous containers. It is your mission to aid your poinsettias in growing as healthy as possible.

Another factor other than the exposure to light and the overall plant condition is the temperature. Freezing weathers are lethal not only to their color but also to their life. Keep it steadily warm within the 60 to 70 degrees F range.

 

 

What Are the Benefits of Planting Poinsettias and Other Plants in a Mini Greenhouse?

There are many benefits that come with greenhouse gardening, but most people are hesitant to try because of the initial cost that comes with building or buying a greenhouse. However, mini greenhouses offer a more affordable solution while providing the same benefits as a regular greenhouse.

You’ll be able to grow beautiful flowers and other crops in it. Other benefits of planting in a mini greenhouse include the following:

 

Great for starting seeds

A greenhouse is a great place to start seeds before transplanting them to your garden. Greenhouses are perfect for seeds since it provides them with continuous warmth and protection. You don’t need to place them in garages, basements, or mud rooms.

 

Protect your plants from pests

Pest infestations can be bad for your plants. Deer, rabbits, raccoons, thrips, aphids, mealybugs, and other pests and animals can be persistent, and can easily damage your plants. placing your plants inside a greenhouse and placing screens and traps can protect your plants from these critters.

 

Extend your plants’ growing season

Extending the growing season is one of the many reasons why gardeners use greenhouses. You’ll be able to grow more and have a wide variety of plants to choose from. With a greenhouse, you can control the growing environment by using heating or cooling systems, grow lamps, fans, and more. You can use greenhouse equipment to create a warmer or colder environment, or whatever is suitable for your plants.

 

The Bottom Line: How Do Poinsettias Change Color?

While there are many answers as to how do poinsettias change color, light is indeed the main factor. However, that does not mean that you should focus on that aspect alone. Don’t forget to pay attention to the Christmas Star’s need for nutrients as well.

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.

 

Conclusion

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.
