How To Apply Florel Correctly

To properly learn how to apply Florel, consider how much the ratio is for creating a solution before spraying it at specific periods. Growing in a greenhouse should help you get healthy and productive plants, but using a growth regulator that helps with branching and prevent budding can further improve your plants’ quality. After all, it’s common nowadays for gardeners to experience underwhelming branching and growth rates, especially with annuals.

It would be best if you also remembered that you shouldn’t be relying on Florel alone. Proper maintenance and practices are a must to experience great rewards from crops. Adjust the ideal conditions for your plants using a greenhouse and read below how to apply Florel correctly.

How To Apply Florel Correctly

Gardening 101: How To Apply Florel


Mixing the solution

To start, create a solution consisting of Florel and water. Three quarts of Florel in 40 to 100 gallons of water per acre will be your ratio. For a spray solution, you should have 300 to 750 ppm of plant growth regulator.

The concentration of the solution is a crucial aspect of the proper usage of Florel. Seasoned gardeners recommend starting at 500 ppm, and how much more or how less you should go depends on your plants’ reactions. Some plants like fuchsia and impatiens are particularly sensitive to Florel, so spray them with 250 ppm instead.

Another component is water and its pH level. The ideal is 4.0 to 4.5 for adding Florel. This is because the chemical tends to lower the water pH, which can burn and damage plants. 

In some cases, you may also need to add a buffering agent to prevent the pH level from getting too low; otherwise, the effectivity of the solution will reduce. 


Spraying application and intervals

Spraying should start immediately after you prepared the solution. Never hold it overnight, and the longest you can wait is 3 hours. The application itself is straightforward, and you should be aiming to cover all the leaves and stems of your plants.

The solution will have no use in the soil because the roots are not as effective as the leaves and stems are. You want to see the leaves wet for up to 4 hours to guarantee effect. In turn, this will also require you less spraying. 

The brand also recommends to have 10-day intervals when spraying and only harvest after 42 days of last application. Additionally, remember that you can only have six spray applications in a year.


When to use Florel?

It’s advisable to spray Florel when your plants have two to four leaves. However, the plants should also be healthy and not stressed as the chemical will exacerbate this condition. You’ll end up with weak plants and yellow leaves. To ensure healthy plants for Florel application, keep them in a greenhouse and water properly.

When to repeat the application of Florel? This will depend on the reblooming times of your crops. For example, geraniums can have only one application than lantana since the former takes eight weeks to rebloom.

You can also spray Florel during propagation when you are weaning the plants from mist to eliminate the need for pinching and increase branching. However, it would help if you stopped it two weeks before you’re going to collect cuttings. Otherwise, your propagations can halt development, which shows as rooting problems and yellowing of leaves. 


What Is Florel?

You are probably familiar with Florel as a growth regulator. But to further understand its proper usage, you should know more information about this chemical. What does Florel do for plants? 

Florel is a chemical that produces ethylene, which plays a significant role in plant growth and development. What it does for you includes taking off early flower buds and even increasing your plants’ branching. These effects eliminate the need for pinching, and your plants will still grow efficiently and provide you more cuttings. 

You can expect faster branching on your crops when you spray Florel immediately after potting when the plants root out or in propagation for more efficient stock production. Additionally, those that cultivate vegetative annuals will benefit the most with this chemical since it delays flowering and even takes off flowers, so the plant only focuses on growing. You no longer have to do the disbudding yourself, but this will still depend on the type of plants you have.


Other uses of Florel

Besides regulating growth and increasing branching, Florel is also useful for plant breeding and generally throughout the plant’s production stage. Remember that you can use it for stock culture, propagation, the young plant’s development, and when the plant finished growing. 

What’s excellent with this spray is that you expose or deliver ethylene inside the plant tissue in doses that won’t damage. And yet still, Florel application should give you the beneficial effects of ethylene discussed earlier on. 



Everybody wants a productive garden, and using and maintaining a controlled ideal environment should help your plants thrive throughout their life cycle. However, you must also learn how to apply Florel, as knowledge for beneficial chemicals goes a long way. For example, you can be more cost and time-efficient since it helps regulate your plants’ growth and branching.

Additionally, using Florel is easy as long as you follow the recommended solution and intervals. Think of it as benefiting from the chemical ethylene without the risk of potential drawbacks.

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.
