Growing a Grape Vine In a Greenhouse in Details

Grapes are not too challenging to grow. There are two ways of growing a grape vine – in a greenhouse and outdoors. According to experts, the best quality grapes are those which are grown outdoors because sun rays are essential for the fruit to ripen fully. Grapes vines are climbers in nature, so they fundamentally require substantial support to climb. The tendrils need sturdy support such as wires, trellis, posts, and a lot more on a well-built wall.

If you are residing in the US, you can cultivate grapevines both outdoors and inside greenhouses. In Canada, farmers practice grafting and various other mechanical techniques like soil slotting. Nowadays, people seek an interest in organic farming by raising sustainable vineyards through an ecologically sensitive approach. 

If you are a real gardener at heart with an overwhelming passion for growing trees, it is more likely that at one point or the other, you will have a desire to grow grapevine at an open or enclosed garden. Who knows! One day you may become the sole owner of a vineyard yielding extraordinary grapes giving people the chance to buy the best grade fruits. Even restaurateurs will start purchasing the product from you as grapes are significantly used to prepare desserts. 

Have you ever had a close encounter with grapevine?  The fully grown grapevine is truly delightful to watch as it grows bigger with beautiful leaves covering the fruits, especially during the autumn season.

Grapevine cultivation in Greenhouse


Grapevine cultivation in Greenhouse


It is said that the best grapevines are those cultivated in Greenhouse because most greenhouses in the US comprise a structure made of galvanized tubes with polyethylene foil; the enclosures invite maximum sunlight; thus, helping grapevines to thrive better in a controlled temperature. 


Planting methods


Planting the roots outside the Greenhouse

Studies say it is considered to be one of the best-practiced methods. The process involves the planting of grapevine with its roots placed outside of the Greenhouse. The approach renders the plant a whole lot of advantages alongside a set of disadvantages.

    1. The plants can be watered easily and sometimes naturally due to rain.
    2. One of the disadvantages is that the process may go slower down the plant growth as the roots which are surrounded by soil turn colder since the temperature cannot be controlled.


Planting the roots inside the Greenhouse

When the roots of grapevine are planted inside a container, it shows up some advantages and disadvantages, like the following. Get a quick view now: 

    1. As the temperature remains controlled, the soil becomes warmer, which ultimately leads to quicker and steady growth.
    2. Proper blending of soil is primary for improved growth of grapevine. A blend in a proportion constituting 20% coarse grit, 60% loam, and 20% peat is ideal. The bone powder can also be blended with the mixture for better results.


For both set-ups, you will need to ensure that there is sufficient drainage of excess water. Also, proper maintenance is a must. 


Sunshine and space

One of the most important factors which play a vital role with regards to maintaining the quality of grapes, their sweetness, ripening, attractiveness, is the exposure of the plant in sunrays. 


To grow grapevine, you don’t need a huge space; even a small, organized area works fine for cultivating grapevine. If allowed, grapes ramble, forming bigger clusters. Meanwhile, you will need to execute proper knowledge to foster pruning, which will ultimately help the plant reap better quality fruits. Furthermore, you must remember that land plays an important role in boosting grapevine growth, just like its application in commercial vineyards.


Methods of growing grapevines

Firstly you will require a supporting frame and tie the vine to it; as it’s a climber, it requires strong support; or else there are other methods used for fixing grapevines at sides of a greenhouse. These suitable methods are applicable based on individual requirements and situations. Additionally, you must note that all these methods will involve usage of three strong wires tightly tied at 18 inches of interval till the length reaches 6 feet.


Two methods of growing grapevines


Cordon (Guyot) process

It is one of the simplest of processes requiring much less space. It focuses mainly on the development of one or two primary stems. Post vine planting, the plant is trimmed to one-third of its actual growth. If there is a growth of any side lateral, the same is trimmed back. Vines are expected to thrive during the summer season, keeping in mind that you will need to trim the side shoots and organize them at regular intervals.

When the second autumn arrives, trim the vines to 36 inches. Also, don’t forget the side laterals. They need to be pruned to one bud only, especially from the primary stem.

You will then see the primary stem thrive again during the same growing season. By the end of the year, the stem is needed to be trimmed to half its size. The Maximum length of side shoots must not extend beyond 1 inch.

Untie the grapevine when January arrives. Make sure you pull down the upper portion of the stem towards the earth which will, in turn, allow the upward movement of the buds, at that very moment you need to release the stem so that it can go back to its original position.

Now that the grapevine is ready to bloom and bear fruits, all you will need to do is trim down the growing tips just above the flowers. The primary shoot will continue growing strongly; only it needs to be tipped when it reaches a desirable height.

Meanwhile, during the month of December, the laterals need to be trimmed to an inch.


Fan (Spur & Rod) process

For this process, all you will need is to allow the development of a single primary stem. It should be further taken into account that the shoots on either side should not have more than 1 or 2 leaves. Upon completing a year, the primary stem requires a trimming, so that it stays at the height of 15 to 18 inches from ground level.

These will lead to results during seasons like spring and summer when new shoots will evolve, which will further need to be vertically trained during their growth process. By the end of autumn of that same year, tie up one shoot horizontally down on the left side and another on the right side; also, one vertical shoot should remain at the left.

Trim down the stalk to 3 or 2buds. Now the vines will resemble a “T” shape. Although the shoots will remain tied down, they will still stay pliable and flexible.

During the next summer, you will see two or three shoots rising from the central stem, which again needs to be trimmed after they reach the desired height. Now, from these horizontally tied shots, several new shoots will start growing vertically upwards, some of them will require tying again while the rest will need to be trimmed off. You will then see the vine will resume a pleasing shape.


Feeding the plants

Like various other plants in a garden, grapevines require proper feeding to reap the best-grade fruits. Good quality fertilizers need to be added to the soil in February or March before growth occurs. You can use at least 2oz’s/sq yard. Take around ½ oz of potash for better results. 

Also, the plant can achieve larger berries simply by watering the vine at regular intervals and during the right season. March end till mid of April is ideal for watering the plant. Also, you will need to water the earth once a week to get good results. Morning is considered as the perfect time for watering.

During early autumn, make sure you have cut off excess watering, which may lead to the splitting of grapes. You can use Netafim’s sprinkler to spray water.  


Yielding the grapevines

Hold your patience! Wait till the time arrives. The taste of grapes enhances with ripening. If you are harvesting grapes for desserts, take some time off your busy schedule and taste a few fruits at regular intervals. Make sure you taste them after the grapes have started showing that they are fully ripened. Cut out the weighty bunch with sharp and sleek scissors as manual pulling might cause damage.

Grapes used for wine-making do not require being ripe, which is otherwise necessary for preparing desserts. Seeing to it that the fruit has a desired level of juiciness is mandatory.

If you are harvesting grapes in Greenhouse, there is no need for you to worry; keep a tab on how it is growing.

Growing grapes on the WEST or SOUTH facing walls always gives better results than growing them on the NORTH or EAST walls because the former allows the vine to receive ample sun rays, which are essential for its growth. Grapes growing under shades lack taste.


Fungal attack

It is one of the greatest threats to grapevines. You need to take proper care and conduct regular checks to avoid the dreadful fungal attack. Poor air circulation leads to fungal attacks for vines grown in Greenhouse and those grown outdoors.

To keep away from fungus, you can use the anti-mildew spray at regular intervals, which will keep the fungus at bay. Secondly, the Pruning method of cultivation can be practiced to prevent fungal growth. As pruning method does not allow too much clustering, hence the fungus cannot spread.


Insect attack

Little insects sometimes damage the leaves of the grapevines by digging out small holes in them. As soon as you notice such signs, rush to the site without wasting time, as you will need to apply insecticides as a preventive measure. 

Sometimes whiteflies are also noticed attacking the grapevines, which are grown under a shade; hence proper care needs to be taken by applying anti fly spray or powder to prevent loss.



From mid or towards the end of summer, grapes start swelling up quickly. You should take proper care of grapes at this point, or else the berries’ size might vary. It might get stuck to a smaller size instead of growing up juicy. If you want larger grapes, you need to perform proper thinning, which will lead to the growth of grapes.

Sleek, sharp scissors are an essential tool to perform thinning, removal of inner and rotten fruits; this should be practiced while keeping the outer and shoulder portions intact. Also, the method should be practiced regularly to achieve good results.


How to grow seedless grapevines

With the evolution of modern technologies, seedless grapevines are increasingly cultivated. The seedless grapevines grow well in the southern parts of the world than compared to other countries. 

They do grow well in covered areas as well as in the Greenhouse.


Different types of grapes

Following are the tasty varieties of grapes people like to have:

  1. Royal Muscadine
  2. Theresa 
  3. Bacchs
  4. Buckland Sweetwater.
  5. Boskoop Glory
  6. Alicante.


Pots and container used for growing grapes:

Few things are to be kept in mind while growing grapes in a pot or a container. The size of the container should be taken care of for the best results. Around half a barrel is a perfect size. A proper drainage system is essential for better results. All kinds of grapes can be grown in a pot or a container. The quality totally depends on the skills of the cultivator. You need to take care of the watering aspect, as frequent watering helps the grapevines grow faster. Every morning during the season of growth, which extends mainly from April end to October, make sure you have watered the plant, enough.

During autumn, the fruits start to ripen; however, you need to pay attention when it comes to watering the plants, as excess watering can lead the grapes to split.


Other ways to cultivate grapevines

Grapevines can be successfully cultivated if they receive a significant amount of sun rays and a suitable support system for them to climb and grow. Tree trunks telegraph poles, and low walls are places where grapevines can also grow. Sunshine is a significant factor that needs to be considered to ensure the maximum growth of vines. You might see delayed cropping in these cases, yet the yield will be good if it gets going.

You need to provide a proper support system such as bamboo frames or strong wires which they can use to climb up the wall. Once vines get the support, they are expected to give desired results.

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.
