How To Keep Mums From Blooming Too Early

You will know how to keep mums from blooming too early if you understand what factors affect their blooming. Unlike other flowers, mums or chrysanthemums are prone to premature budding, making their finishing short and initiating flower buds before even the reproductive stage. This can be stressful for gardeners because it affects productivity, and the plants will not perform well. 

The good news is that mums are relatively easy to grow, and their optimal conditions are easy to meet, especially in a controlled environment like a greenhouse. Their hardiness zones are from 5 to 9, making them one of the hardiest flowers to cultivate. However, the best time for them to bloom in the fall, so take the time to understand their blooming factors and keep them from doing it prematurely.

How To Keep Mums From Blooming Too Early

Learn How To Keep Mums From Blooming Too Early

The main reasons for the early blooming or premature budding of mums are temperature, day period, and maintenance. As you can notice, these factors are straightforward to control, especially with a greenhouse. This is also the reason why commercial manufacturers grow flowers indoors



Exposure to extreme conditions like high temperatures, excessive rain, and low relative humidity can cause mums to bloom early. Therefore, indoor cultivation of these flowers can protect them from these conditions and maintain optimal requirements instead. This is also the same reason why it’s not best to plant or even transplant chrysanthemums outside too early because the cold temperatures outdoors will inevitably trigger early flowering. 

The plants will end up finishing too short, especially during the vegetative phase. The excessive rain can also damage the roots, and low relative humidity causes stress, which are both causes of premature budding in mums. If you’re using a greenhouse, what are the optimal conditions for mums?

The recommended temperatures for mums are from 65 to 70°F, while the relative humidity should be 70 to 90%. But what about the timing for transferring mums outdoors without encouraging blooming too early? This will depend on your location’s climate, but generally, be on the lookout for mums being exposed to harsh weather. 


Day period

Manipulating the day period is also another way to keep mums from blooming too early. For example, having 4 hours of night interruption will maintain the plants in their vegetative phase. And if you are in the deep south, light your cuttings in propagation year-round. 

Using Florel can also help in delaying the flowering, depending on your varieties. Apply it a week after transplanting or when the mums are fully rooted. However, gardeners recommend using lighting and temperature to prevent premature budding because of the various limitations with Florel. 



As previously discussed, the temperature and light both affect the time when mums bloom. However, maintenance also plays a role in premature budding. The stress from heat or root loss from harsh weather is preventable by misting the plants. 

Keeping mums well hydrated until they are 60% of their final size will prevent early blooming. Additionally, low fertility will also restrict your plants’ vegetative growth, pushing them into reproduction before reaching the ideal size. Therefore, keeping mums well-fed after transplanting should promote vegetative growth and overcome premature budding. 

Experts recommend a phosphorus-rich fertilizer, especially when you just transplanted chrysanthemums. This will promote rooting and encourage them to grow and develop lateral breaks instead of undergoing reproduction. However, be wary of control-release fertilizers because high salt also halts plant growth and causes stress on your plants. 

If you notice that your mums indeed start blooming too early, you can pinch flower buds and apply fertilizer. When done early enough, you shouldn’t experience a significant delay in their growth. 


Why Is It A Problem When Mums Bloom Too Early?

It’s a gardener’s headache to see mums blooming too early, but why do we have to prevent premature budding plants? Let’s say that you are growing mums for commercial use. If they bloomed too early, then you’ll also be too early from your target sales date. 

It can also be stressful when some mums reach budding earlier than others, especially when you have a schedule. If the plants cease growth earlier than necessary, you’ll end up with dead flowers and lower quality. Even if they don’t die, you have a smaller plant with short stems without even developing leaves. 

Remember that mums are known for having a beautiful round growth, and premature budding will cause a lopsided shape instead. The good news is that proper knowledge of mums’ conditions and growing them in a controlled environment in a greenhouse should prevent them from blooming too early. 



If you want to achieve high-quality, healthy, and rounded mums, it’s vital to prevent premature budding. Learning how to keep mums from blooming too early is quite simple in the sense that you understand three factors that affect the flowers’ budding. They are temperature, day period, and proper maintenance. 

These considerations are all easy to control in the greenhouse. You have to understand that cold temperature, harsh weather, low humidity, lighting, and even insufficient water and fertilizer contribute to premature budding. In the greenhouse, you can maintain the optimal indoor conditions so the mums don’t undergo stress that can encourage them to bloom early. 

If they are well-watered and fed, they will also continue to grow instead of quickly experiencing the reproductive phase.

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.
