How are strawberries grown in the open field in the Netherlands?

Dutch strawberry cultivation technology allows you to harvest all year round. This is a profitable idea for small businesses, but recently it has also attracted the interest of those who grow strawberries in their personal plots. It is important to consider all the details of the process.

Method of growing berries in a greenhouse all year round: the essence of the method

From the name it is clear that this method was invented and used in Holland.

This technology creates a certain microclimate in the greenhouse, which minimizes losses from plant death and disease. Seedlings are also planted all year round.

The main difference from the standard breeding method is that the plant is used once, after fruiting it is replaced by another. As a result, the owner of the greenhouse has a constant harvest and no losses from dead plants.

Seedlings must be planted constantly, this is the only way to ensure a continuous harvest. To grow all-season strawberries in greenhouses, you will need specialized equipment.

When choosing a variety, it is desirable dwell on self-pollinating repair varieties. The primary seedlings can be purchased in special stores, the subsequent one can be grown from the mustache. Seedlings are also grown from seeds, but this is a more laborious process.

One of the features of the method is lack of contact of fruits with the ground... Therefore, they do not deteriorate and do not get sick.

To save space, use a vertical landing. This helps to efficiently use small areas for maximum profit.

The varieties have advantages: Selva, Maria, Baron, Darkness, Tribute, etc.

Beyond the obvious advantages in technology there are also difficulties:

  1. Providing a constant flow of planting material. Seedlings should be all year round. It is profitable to grow it for small volumes of production, and to buy it on an industrial scale.
  2. Indoor lighting and climate. Daylight hours are artificially extended, and the temperature must be constantly comfortable.

Breeding strawberries using Dutch technology step by step

First you need equipment:

  1. Container for growing strawberries... These can be plastic containers or ordinary flower pots. Special polyethylene bags with holes or propylene pipes are also suitable. At home, you can do it yourself. In the room, the boxes can be arranged in several tiers, the main thing is that everyone has enough light.
  2. Irrigation system... The most commonly used drip irrigation and devices to provide humidity in the room.
  3. Lighting... The choice of artificial light must be approached carefully, this is the basis of success.It can be daylight or professional lamps.

How are strawberries grown in the open field in the Netherlands?Necessary equipment: container for planting, irrigation and lighting system

Lighting

For a regular harvest daylight hours are desirable to extend to 12-16 hours... In the summer there will be enough natural light, and in other seasons you will have to use artificial lighting.

Fitolamps are installed in the greenhouse, or, as a more budgetary option, ordinary, energy-saving ones.

Standard filament bulbs are sometimes used, but they are very expensive in terms of electricity bill.

Watering

For greenhouse irrigation watering is used, in which moisture does not fall on the ground parts of the plant... Consequently, they do not get sick, and water consumption is saved.

The greenhouse is installed drip irrigation system... The equipment can be purchased from specialized stores.

For a small production or for a home garden, you can use plastic bottles in which there are straws.

When adjusting irrigation, achieve a flow rate of 3-4 drops per minute. In this way, a sufficient humidity level can be achieved.

Seedling soil

Simple land is not suitable for such a growing technique. For the manufacture of the substrate, you will need perlite Is a rock. It is mixed with peat.

The soil is cleaned soil, preferably loamy and with a low degree of acidity, with an admixture of river sand and compost. Plus a glass of ash and sawdust with urea.

Microclimate creation

The efficiency of the process depends on the overall climate that is created in the greenhouse. Ideal temperature for growth and fruiting - 18-25 degrees.

At temperatures below 12, growth slows down and the formation of berries stops. Excessive heat is also not welcome.

To prevent fungus from forming on the ground, the air humidity should be monitored and, if possible, ventilated the greenhouse. Spray regularly.

Air humidity is maintained in the region of 70-80%... To maintain the desired moisture level, it is practical to use reservoirs with water, placed in different corners of the greenhouse.

Planting and leaving

Staggered strawberries... The distance between the plants is about 25 cm. If ready-made chilled seedlings are used in production, they must first be brought into a warm room.

Strawberries are planted at a slight angle... The distance between the bushes cannot be reduced, since the berry will turn out to be small with frequent planting.

If the varieties do not self-pollinate, a pair of beehives should be installed in the room where it grows. If this is a home production, pollination can be done by yourself using, for example, fans, blowers or a brush.

Plant care is not difficult. All that is required to maintain the humidity of the air and soil at the desired level. Monitor the temperature.

After harvest you can use the plant to get seedlings. To do this, the resulting mustache is rooted.

After that, the mustache is carefully removed. Then they are sorted by the number of peduncles and strength. And then they are sent for storage at a temperature of 0-2 degrees.

For constant photosynthesis need to maintain carbon dioxide levels... This is done by lighting candles.

Growing strawberries using the Dutch method is very effective and helps you get a harvest in just a month.

With proper care and adherence to all the nuances up to 50 kg of berries can be harvested from one square meter of the greenhouse.

Fragrant red strawberries can be called a real symbol of the coming summer, because at other times of the year it is unlikely that there will be an opportunity to feast on the berries of local crops.And yet there is a technology that allows you to get crops all year round, even in less than ideal conditions.

The essence of Dutch technology

Breeding strawberries in the Dutch way provides a stable profit, because the crop can be harvested all year round.

How are strawberries grown in the open field in the Netherlands?

When growing strawberries using Dutch technology, the berries do not touch the ground.

The essence of the method can be reduced to several main points:

  • Indoor cultivation... Strawberry bushes are planted in containers, boxes, pallets, while the fruits do not come into contact with the soil, which means they avoid the development of many diseases and retain their presentation for a long time.
  • Regular planting of seedlings (about once every 1.5–2 months, after successful fruiting). Such measures ensure continuous productivity.
  • Creation of special conditions for the growth and development of culture (equipment, lighting).
  • Regular feeding of strawberries.

Advantages

How are strawberries grown in the open field in the Netherlands?

Harvested every 1.5-2 months.

The advantages of this growing method are obvious:

  • stable harvest;
  • absence of diseases and injuries caused by pests;
  • attractive presentation of berries;
  • excellent taste;
  • profitable use of minimal areas;
  • return on investment.

Maximum use of the usable area is achieved by vertical transplanting... For an even more efficient organization of the process, the best varieties are selected, planting material is grown independently, an optimal microclimate is created.

Varieties for cultivation

How are strawberries grown in the open field in the Netherlands?

Self-pollinating strawberry varieties are needed for cultivation using Dutch technology.

The best varieties for growing in the Dutch way are:

  1. Darkness.
  2. Baron.
  3. Selva.
  4. Maria.
  5. Tribute.
  6. Polka.
  7. Sonata.
  8. Marmalade.

Difficulties

How are strawberries grown in the open field in the Netherlands?

For commercial cultivation of strawberries, you will have to purchase ready-made Frigo seedlings in large quantities.

Challenges that farmers may face:

  • constant provision of planting material;
  • lighting and microclimate.

On a small-scale farm, it is more profitable to grow planting material on your own. If we are talking about an industrial scale of agricultural holdings, then it is more expedient to buy seedlings in large wholesale lots.

Necessary equipment

How are strawberries grown in the open field in the Netherlands?

A greenhouse is needed to grow strawberries year-round.

Speaking about the necessary equipment, a novice agrarian will need:

  • a place to install a greenhouse;
  • containers for seedlings and containers for growing crops;
  • irrigation system;
  • good lighting.

Lighting

For a stable harvest, it is necessary that daylight hours last at least 12-16 hours. In the summer, you can save a lot by using natural light, but the rest of the time you will have to shell out significant sums for electricity consumption.

LED lighting for strawberries.

Some experts insist on using in greenhouses special phytolamps, however, it is also acceptable to use conventional and energy saving varieties. Standard filament fixtures add a significant increase in lighting costs.

The range of lighting fixtures should be close to sunlight, then after 10 days it will be possible to observe flowering, and after 35-37 days - fruiting varietal strawberries.

Drip system

The drip irrigation system has many advantages:

  • localization of water supply;
  • reduction of evaporation losses;
  • elimination of water losses;
  • weed reduction;
  • maintaining air-water balance;
  • simultaneous feeding;
  • process automation;
  • the ability to use in any soil and topography;
  • use in windy weather;
  • low energy consumption;
  • reducing the level of fungal diseases and infections.

The flow of moisture directly to the root system of the plant does not allow the soil to swamp or dry out. Water does not hit the leaves and does not cause sunburn.The optimal level of watering is 3-5 drops per minute.

Equipment for installing a drip irrigation system can be purchased in specialized stores, or you can assemble it yourself using the simplest materials at hand.

Planting strawberries

How are strawberries grown in the open field in the Netherlands?

Strawberries are planted in a specially prepared substrate, the main components of which are perlite and cleaned soil.

Dutch technology requires special soil.

  • To obtain it, purified soil in a low degree of acidity is mixed with river sand, compost, ash, sawdust and urea.
  • But the main "secret" element of the mixture is perlite - a rock of volcanic origin.

In a summer cottage, you can take loamy sod soil as a basis. Ash is often replaced with chalk or dolomite flour. But organic matter is also used: manure, humus. As for the amount of river sand, its volume should not exceed 10% of the total mixture.

Before planting seedlings, the soil is well mixed, all foreign inclusions are removed, the soil is saturated with oxygen and nitrogen.

Seating is carried out in a checkerboard pattern at a distance of 25-30 cm from each other... Finished seedlings first "rest" by raising their temperature to the air temperature of the greenhouse, as the planting material is stored in a cool, dark place.

Tips

How are strawberries grown in the open field in the Netherlands?

Strawberries in separate pots.

  • Do not reduce the distance between landings., wanting to save money and plant as many bushes as possible. This will affect the size and taste of the berries.
  • In the absence of self-pollinated varieties in the greenhouse, it is required to install a hive or pollinate yourself with a brush and fans.
  • The main thing to remember is temperature and watering.... After the first fruiting, the plant is replaced with a new one. The "old man" is used to obtain seedlings by rooting a whisker. The carbon dioxide level can be adjusted by lighting the candles regularly.

Containers for planting

How are strawberries grown in the open field in the Netherlands?

Options for homemade strawberry containers.

A little about containers for planting seedlings. The latter can be used containers, boxes, polypropylene pipes with special holes, plastic bags... The main thing to consider is the distance between the bushes, which is sufficient for the normal development of the root system.

Strawberries in horizontal PVC pipes.

Vertical beds of strawberries.

Plants must be well ventilated... This will allow them to resist various putrefactive infections, and will also have a positive effect on the tasting properties of the berries.

Microclimate

How are strawberries grown in the open field in the Netherlands?

In the greenhouse, it is necessary to maintain a certain temperature regime.

According to Dutch technology, the optimal microclimate ranges from +18 ° C to +25 ° C... However, during the period of mass flowering, the air temperature should be kept at around +21 ° C.

Low temperatures cause a prolonged flowering period, high temperatures cause low pollination and ovary formation.

Air humidity

Air humidity is 70–80%.

With a lack of moisture, spraying is carried out, with an excess - ventilation. Excessive moisture can lead to the development of fungal infections, which is why it is so important to monitor these indicators. To accelerate the growth of seedlings, you can increase the% of carbon dioxide.

conclusions

In fact, Dutch strawberry cultivation technology is not as complicated as it seems at first glance. Most of the nuances of cultivation are taken into account when breeding crops in open field conditions. The main advantage of this method is high yields all year round. If all the requirements of agricultural technology are met, up to 50 kg of juicy sweet berries can be obtained from one square meter of the greenhouse, and this is already a month after planting.

Garden owners are accustomed to growing vegetables, herbs and flowers in greenhouses. But what about the other half of the horticultural pie, strawberries? Experts have developed techniques that allow greenhouse owners to produce berries in the off-season. Among others, the method of growing strawberries according to the Dutch technology, as well as the Finnish agro-method of cultivating berries, stands out. Thanks to them, you can grow juicy fruits all year round. Let's consider their advantages and disadvantages.

Nuances of growing strawberries in winter

The Dutch method of cultivation consists exclusively in greenhouse cultivation, while according to the Finnish method, the berry was originally grown in the open field. Only in recent years have the Finns started to actively use their technology for cultivation in greenhouses.

How are strawberries grown in the open field in the Netherlands?

Dutch strawberries yield very high yields

The methods of growing strawberries all year round are quite simple. To obtain a rich harvest indoors, special equipment is required that will control humidity, lighting and temperature conditions.

An off-season Dutch strawberry farming technique has been designed to produce large quantities of fruit for sale. To use it "for yourself" is fraught with large material costs.

If you have a desire to get a harvest of berries in winter, it is recommended to test your capabilities in small areas. And it is better to start from the windowsill or balcony. In case of failure, the impact on the budget will be minimal.

How to choose planting material for a rich harvest

The methods of growing strawberries in a greenhouse all year round are based on the constant planting of new seedlings (maximum period 1–2 months) so that the crop ripens constantly. But where to get seedlings in the offseason?

How to prepare seedlings

Throughout the year, agricultural firms offer at an overpriced a special type of seedlings - "frigo", which you can easily prepare yourself on your site.

Such seedlings are well-developed strawberry bushes, dug out in time in the fall and "frozen", that is, artificially cooled. They are stored at temperatures close to zero in the refrigerator or in the basement, and when it is time to disembark, they are removed and planted.

Under natural conditions, strawberries are "canned" on their own, under a cover of snow. The main task is to recreate the atmosphere for "artificial hibernation" in order to "awaken" dispersion if necessary. This is the main secret in the technology of growing strawberries all year round. After receiving the fruits, the seedlings are discarded.

Selection of planting material

It does not take much investment, effort or time to harvest seedlings. It is quite possible to grow it in the country. It is advisable to prepare a plot for breeding seedlings in the fall. For this:

  1. For one hundred square meters, 5 kg of superphosphate, 6 buckets of manure, 2 kg of potassium chloride and about 15 kg of lime are introduced. The soil will be ready by spring.
  2. It is advisable to plant plants on ridges about a meter wide at a distance of 35-45 cm.
  3. In the first year, all whiskers and peduncles are removed from the mother plant. The next year, from each bush, you can get 20-25 whiskers, which must be rooted.
  4. The resulting sockets are removed in October or earlier (at t somewhere around 0 ° C).
  5. Next, the seedlings are cleaned of the remnants of the earth and dried leaves.

The structure of the strawberry bush strawberry

Remember! The roots must not be shortened and washed with water.

Then the planting material must be sorted according to the following principle:

  • class A - 12-15 mm in diameter, with two peduncles;
  • class A + - 15-20 mm in diameter, up to four peduncles;
  • class A extra + - diameter exceeds 20 mm, and the number of peduncles is more than four pieces.

This classification demonstrates the amount of the expected harvest that can actually be obtained in the season:

  • class A = 150 g;
  • A + = 200 g;
  • class A extra + = 400 g per bush.

If you did not succeed in sorting the seedlings, do not be discouraged: each class has its own advantages. For example, bushes with a large diameter require careful and constant feeding, because they quickly lose nutrients, and small seedlings give a smaller but stable yield.

On a note! The day before disembarkation, the seedlings are brought into the room for defrosting.

Strawberry seedling classes

What varieties to use

You need to choose high-yielding varieties for breeding seedlings, preferably self-pollinated. You can use Dutch strawberry varieties: Tristar, Selva, Elsanta, Maria, Tribute, Octave, Sonata, Polka, Honey, Mrak, Marmolada, Baron Solemacher, Darselect.

Please note! Even in unheated film greenhouses, early strawberry varieties ripen a couple of months earlier than in open ground.

Mainly the choice depends on the purpose for which the strawberry will be grown. For year-round cultivation according to the Dutch method, remontant varieties of neutral light lighting are suitable, which are replaced only twice a year. If you are looking to produce berries for sale, choose varieties that are fairly dense, transportable, and of the same size.

Dutch strawberry cultivation method

The basic principle of growing strawberries using Dutch technology is to plant seedlings in a container with soil. It can be:

  • plastic bags;
  • boxes;
  • flower pots;
  • pallets;
  • special bags.

Microclimate and irrigation requirements

The Dutch cultivation technique is called forcing. Having awakened and planted strawberry bushes, they need to be provided with nutrients, a special solution with which is supplied to the containers by drip irrigation. Plants can be placed horizontally and vertically. The choice depends entirely on the available space and desire.

Lighting occupies a special place in Dutch strawberry cultivation.

For greater productivity and quick ripening of fruits, plants of 6 m² are enough one daylight bulb for 50-60 watts. It is necessary to light the planting for 16-17 hours. To increase the efficiency of greenhouse lighting, gardeners are actively using reflective materials.

Within 10 days, the bushes can bloom, and fruiting in this case will come in 35 days. In addition to lighting, plants are provided with:

  • Indoor humidity is around 75%. This is achieved by spraying, but must be suspended during the flowering period.
  • Strawberry bushes need regular ventilation. For large areas, a ventilation system is installed, and the presence of carbon dioxide is monitored using sensors.
  • Regular watering, often using a drip system.
  • The temperature is maintained at 17-21 ° C. During the flowering period 25-27 ° C.
  • If necessary, strawberry flowers are pollinated using an ordinary brush. You can use a regular school paintbrush. All that is needed is to gently run it through the flowers every day. There is another method, which is faster in time, - using a jet of air from a fan. In this case, the pollen will reach neighboring flowers on its own.

Varieties of homemade containers

Preparing the soil for planting

For the full development of strawberries indoors, a certain soil composition is required. The best option is a substrate that contains natural soil and synthetic elements. Overripe manure and sandy soil are excluded - diseases and pests are concentrated in them.

The substrate must be sterile and free from germs. Most often it is mixed with steamed peat and perlite, it is also recommended to add coconut fiber or mineral wool. This makes the substrate lighter and more porous.

Features of planting strawberries

Dutch strawberry cultivation technology is ideal for planting in confined spaces. The placement of plantings in hanging containers keeps plants at a safe distance from slugs, snails and diseases that persist in the ground. With this arrangement, the plants do not compete with each other to obtain nutrients and water. Moisture can be retained with water-retaining granules. The compost is checked daily.

A good option for planting is considered to be plastic bags, the diameter of which is a maximum of 15 cm. First, they are filled with harvested soil, and then cuts are made at a distance of 25 cm in a checkerboard pattern. The bushes are planted at a slope of 42 °. This method is very practical, since strawberries can be grown anywhere where it is possible to create the necessary conditions.

Finnish cultivation technology

The Finnish method consists of mulching, that is, covering the soil with a film. This method is used for planting in open ground, for cultivation in film tunnels and greenhouses. It makes it possible to get a harvest from rooted bushes within 1.5-2 months after planting.

Benefits and main ingredients for success

The main secret of the early ripening of berries is the rapid heating of the soil. The planting density is 25-40 thousand per hectare. The distance between the bushes is 25-30 cm. Growing strawberries using Finnish technology has a number of advantages:

  • mulching guarantees uniform heating of the soil and moisture retention;
  • an obstacle is created for the rooting of rosettes and the growth of weeds;
  • nitrate nitrogen accumulates on the soil surface, which enhances the nutrient medium;
  • microorganisms necessary for the full growth of berries intensify their activity;
  • ripe fruits do not get dirty with earth.

Finnish cultivation method

What is required for Finnish technology

The main functional material is a dark film. Mulch cover is used for plantings located in one or two rows. The first option requires covering with a film of up to 1 m. The second method of planting in two rows is more economical for a greenhouse; a film of 1.2–1.5 m is used to cover such plantings.

The film can be black or dark brown. This type of cover is very productive in strawberry cultivation. However, it actively attracts sunlight, which contributes to the drying out of the soil. But when using white film, you will have to fight weeds, and the harvest will appear much later.

Sometimes agrofibre is used, which prevents mold from developing, as the material "breathes". But when using it, you need to increase the number of irrigations, and the cost of the material is much higher than that of the film, which also speaks not in its favor. For Finnish technology, a drip irrigation system is required. This protects the crop from drying out.

Finnish method agrotechnics

  1. Before planting, the soil is loosened to enrich it with oxygen.
  2. Then it is fertilized with horse manure, compost or humus.
  3. A distance of 60–70 cm is kept between the rows.
  4. The soil should be stable within two weeks.
  5. At this time, an irrigation system is placed.
  6. Then the film is pulled and fixed.
  7. Strawberry bushes are planted in pre-made holes.
  8. First, watering the holes is done manually, and then with the help of an irrigation system.

After that, the control system will be carried out using timers. You just have to collect berries in boxes.

Finnish strawberry cultivation in a greenhouse

Dutch and Finnish year-round cultivation technologies are popular all over the world. To get fragrant and juicy fruits, you will need an enclosed space, some knowledge, and a great desire to complete what you have begun, despite mistakes.

How are strawberries grown in the open field in the Netherlands?

Have you ever wondered where fresh strawberries come from in supermarkets in cold weather? How is it grown? In most cases, this is the so-called "Dutch strawberry", the seedlings of which are planted year-round according to a certain technology, which is distinguished by a special method of irrigation, fertilization and planting.

Where to get seedlings in winter?

Do you want to learn how strawberries are grown in Holland, and at the same time try this unique technology on personal experience in order to get ripe tasty berries by winter? To do this, you will need seedlings, plastic bags, a special substrate and a great desire to complete the work begun, regardless of possible mistakes. The cultivation technology is similar to the cultivation of strawberries in bags, but there are still some differences.

Since it is impossible to plant seedlings in open ground from autumn to spring, the Dutch method of growing strawberries is used mainly in greenhouses. At home - on the windowsill or on the balcony, you can also achieve a good harvest of sweet berries if you create an optimal microclimate and strictly follow a proven methodology.

How are strawberries grown in the open field in the Netherlands?

Growing strawberries in Holland

The Dutch method of growing strawberries is based on the fact that the seedlings are planted constantly, every month or two. Then the crops can be harvested almost continuously. But where to get seedlings in the cold season? Agrofirms all year round at high prices offer special strawberry seedlings "frigo", which you can prepare yourself from your own plot. After all, frigo seedlings are nothing more than well-developed strawberry bushes, dug out in the fall and chilled (hence the name). All winter they can be stored at low temperatures in the refrigerator, freezer or in a cool basement, and at the right time they can be taken out and dropped off.

In nature, strawberries are "canned" naturally, under the snow. Your task is to artificially create conditions for "deep hibernation" so that you can "wake up" the seedlings at any time. This is the main secret of the year-round cultivation of strawberries using Dutch technology.

Choose high-yielding varieties for seedlings, self-pollinated if possible. Dutch strawberry varieties, Tristar, Maria, Selva, Elsanta, Tribute, Sonata, Polka, Mrak, Marmolada, Darselect are suitable. Having planted strawberries of the listed varieties on the site (planting strawberries with seeds is possible), in the first year, cut off all peduncles and mustaches from the mother plants. Next year, each bush will have about 20 whiskers, which will need to be rooted - from them, by the fall, you will get strong young rosettes. Dig out the sockets when they are in a dormant period (from the second decade of October), at a temperature of -2 degrees. Remove all large leaves and vegetative shoots from the bushes, rinse the roots and cut them in no case! Your seedlings are now ready for long-term storage.

Optimal conditions for capricious strawberries

In order for strawberries using Dutch technology to develop well and delight you with a bountiful harvest, you need to prepare a suitable soil. It is better to take a substrate for this purpose, consisting of natural soil and synthetic elements to provide the seedling bushes with all the necessary substances. Sandy soil with rotted manure will not work - various diseases quickly accumulate in it and pests appear. The soil must be sterile, free from weeds and microbes. Most often, the substrate is mixed from steamed peat (it has a high absorption capacity and good porosity) and perlite, which improves the aeration of the peat. Even coconut fiber or mineral wool is used as a substrate.

You can plant seedlings in boxes, but the best conditions for growth will be provided by plastic bags:

  • take narrow plastic bags with a diameter of 15 cm;
  • cut holes in them for strawberry bushes in a checkerboard pattern every 25 cm, or in two strips with a distance of 40 cm (with strong thickening, the berries will turn out to be small);
  • fill the bags with substrate;
  • Plant the seedling bushes in the cut holes at a 45-degree angle.

Narrow bags are convenient because they can be placed on a balcony or in a greenhouse in several tiers, getting more berries.

Now you need to take care of watering. Since strawberries need regular watering, but at the same time, water should not get on flowering and fruiting plants, it is recommended to build a system of pipes through which water and fertilizers will flow to the roots of the seedlings. Creating such a system will take effort, but then it will be much easier to care for the strawberries. "Minitubing" can be made from tubes from droppers, taken out of a two-liter bottle of water to each bush. The water in the bottle must be constantly topped up as it goes down.

Secrets of a successful result:

  • to ensure an 8-hour daylight hours, it is necessary to organize supplementary lighting of strawberry seedlings using fluorescent fluorescent lamps;
  • the room temperature in the room must be constantly maintained at the same level, therefore, provide for the possibility of additional heating in advance if necessary;
  • plants also need fresh air - regularly ventilate the room with strawberry seedlings;
  • if you have planted non-self-pollinating varieties, you will have to manually pollinate the plants during the flowering period, brushing over the flowers with a small brush;
  • Plant seedlings in batches so that the entire crop does not fall at the same time.
