How To Pollinate In A Greenhouse Correctly

It’s crucial to know how to pollinate in a greenhouse manually, using bees, or via devices. Pollination is necessary for plants to have a productive greenhouse. After all, it is how they reproduce, so it’s only right for the gardener to know how Pollination occurs indoors. 

It won’t be enough only to learn how to start plants in the greenhouse. But to truly capture the essence of nature indoors, you might have to intervene with Pollination. Successful Pollination will lead to better yield, which, in turn, provides a sustainable profit. 

How To Pollinate In A Greenhouse Correctly

Definitive Guide on How To Pollinate In A Greenhouse

Before learning about manual Pollination, using bees, or device pollination, one aspect of the greenhouse also plays a role in success. For example, self-pollinating plants will rely on the movement of air. But it also keeps the plants healthy, so even those that don’t self-pollinate require this in the greenhouse. 

It’s also important to know that some plants don’t require Pollination. This article will discuss some examples of these crops later on.


Manual Pollination

If you have a small-scale greenhouse, the best way to pollinate is through manual intervention. However, those who have a bigger greenhouse can still do it manually, but it will take time and effort. Manual Pollination, from the name itself, requires the intervention of the gardener.

Generally, manual Pollination is when you move pollen grains from the male flower to a female flower. This is a common practice in growing zucchinis in the greenhouse and other plants like tomatoes. Some plants have male and female parts, while others require two plants in cross-pollinating crops. 

Depending on the type of plant you have in the greenhouse, the method for manual Pollination varies. Some use an electric toothbrush to mimic pollinators, while others gather pollen with a soft brush. If you want to speed up the fruiting of your crops, manual Pollination will also be useful. 


Use of bees

A more natural way of pollinating the greenhouse is by introducing bees. Bees are one of the most reliable pollinators, so, logically, having them indoors will help with your plants. If you also have a bigger greenhouse, using bees will save you more time.

How do bumblebees help with Pollination? The hairs on the bee’s body attract pollen grains, which helps with pollen transfer for successful Pollination. It’s successful because it’s typical for one bee to focus on one plant only.

Some examples of crops in the greenhouse that will benefit from bee pollination are berries, eggplants, and tomatoes. If you’re cultivating flowers in the greenhouse, it’s also beneficial to have bees throughout the growing season. However, do note that if your greenhouse uses pesticides, you can assume that using bees for Pollination would not fit.

If you indeed think that bees are appropriate for your greenhouse, a cost-effective yet efficient way to introduce them is using hive boxes. However, bumblebees can visit your greenhouse as long as you provide an enticing environment for them. Manipulate a bee’s behavior by having a water source nearby and a location in the south or southeast for their hive. 


Device pollination

If the manual and natural Pollination doesn’t seem fitting for your greenhouse, you can also pollinate using devices. There are specific devices that will help spread pollen to guarantee that your yield indoors will be optimal. There are also electric pollinators you can use to vibrate onto the plant so that it releases pollen. 

If you’re a bit more imaginative, leaf blowers can also help increase the greenhouse yield. However, note to use it at a low setting, three feet away from the plant for 20 seconds, so you don’t damage the crops. Gardeners are impressed with using leaf blowers towards flowers in particular. 


Which Plants In The Greenhouse Require Pollination?

If the crops you have in the greenhouse produce fruits and seeds, you can assume they require Pollination. To get the optimum yield, you need to ensure that your plants get pollinated. For greenhouse gardening, self-pollinating plants like tomatoes, eggplants, and peppers are more straightforward to cultivate since they can fruit without other plants’ needs. 


Which Plants In The Greenhouse Don’t Require Pollination?

If the plants in your greenhouse don’t produce seeds, they don’t require Pollination. Some examples of these crops are green leafy vegetables, herbs, and root crops. Therefore, lettuce, kale, cabbage, broccoli, brussels sprouts, rosemary, basil, ginger, onion, beets, and potatoes can multiply without needing Pollination. 

If all of your plants indoors are composed of these crops, you can skip the need to pollinate; however, if you have different plants in the greenhouse, gauge which pollination technique matches your needs. 



If your greenhouse crops produce fruits and seeds, you need to learn about Pollination to guarantee good yield. Knowing how to pollinate in a greenhouse means studying which type of technique you think is suitable for you. For example, small greenhouses can thrive with manual Pollination, while using bees can help those with large-scale fruit production. 

Pollination is a simple process to understand. Depending on your plants and if you think you need to intervene, you can choose the appropriate method to keep your greenhouse productive. Like the many adjustments to mimic mother nature indoors, your plants’ reproduction also requires knowledge on your part.

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.
