Upon assembly these necessities, you’ll procure the benefits of nursery planting amid the conditions exterior.

Now and then, cultivators lean toward establishing petunias rather than developing them from seeds. In this strategy, you need to root the plants for 2 to 3 weeks between 64 to 75°F.

The advantage of establishing or utilizing cuttings is that the plants you’ll grow are comparative to the initial and sprout prior.


The Optimal Temperature For Growing Petunias

Petunias are generally low-maintenance plants, but they can survive as they were inside a particular temperature. It’s necessary to ensure your plants from the harsh climate if you’re living in an area with extraordinary warm or cold.

Whereas petunias can resist intensely warm, hot weather leads to expanded water vanishing. Amid hot summers, deliver your petunias additional water. The soil ought to be wet to the touch, but not excessively damp or sloppy.

Most petunias solidify to passing at approximately 30 degrees Fahrenheit. So what are the optimal temperatures in a greenhouse for growing petunias? Petunias develop in locales where up to 210 days out of the year are over 86 degrees Fahrenheit. That’s the society’s most noteworthy conceivable assignment for warm resilience.

Petunias are tolerant of warm, so you don’t need to water them frequently. Constant watering should be adequate once a week (unless there are drawn-out periods of a dry spell in your region). Maintain a strategic distance from watering shallowly as this empowers shallow roots.


Why Temperature Is Important?

Temperature is one of the most natural components that influence the plant’s digestion system. Considering that plants are attached to the stem, their survival depends on resistance reactions’ proficient actuation to warm push.

Extreme temperatures influence plant development in various ways; the foremost self-evident is the impacts of warm on photosynthesis. Plants utilize carbon dioxide to create oxygen and breathing, an inverse handle in which plants use oxygen to produce carbon dioxide.

The impact of temperature on plants shifts broadly by variables such as introduction to daylight, dampness waste, rise, the distinction between day and night temperatures, and nearness to encompassing rock structure.

Temperature has huge effects on most plant forms, counting photosynthesis, transpiration, breath, germination, and blossoming. As temperature increments (up to a point), photosynthesis, transpiration, and breath increment.

When combined with day-length, temperature influences the alter from vegetative (verdant) to regenerative (blooming) development. Depending on the circumstance and the particular plant, the temperature either speeds up or moderates this transition.



Petunias are not the easiest plants to grow, but you won’t have too many issues when you understand how to cultivate and care for them. Temperature is one of the major components so having enough knowledge is a massive start in growing petunias.

We hope this article about what are the optimal temperatures in a greenhouse for growing petunias helped you to achieve that!

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.
