Considering a bag with tomato seeds, in the description you can see the type of plant growth, which can be determinant or indeterminant. For novice gardeners, these terms are not always clear and they are not taken into account when choosing a new variety. Sown previously unknown tomato on the garden without taking into account the type of growth can give either a strong thickening of the plants, or an almost empty area, which negatively affects the overall yield. Therefore, the question arises: indeterminant and determinant tomato, what is it? Consider in detail these two concepts.
The meaning of the term determinant variety
The term “determinant” itself comes from the word “determination”, which in Latin means restriction, therefore “determinant” means “limited” and “indeterminant” means “unlimited”.
With regard to the type of growth of tomatoes: determinant - having a limited growth, indeterminate - unlimited growth.
What are the determinant tomatoes limited by? The growth limit of the top center is a flower brush. This happens as follows: at the end of the shoot an ovary is formed with the fruits, and then it stops growing. Further growth of tomato occurs from the strongest stepchild in the lower axil of the leaf.
Indeterminate tomatoes have no such limitation. The growth of their central apex occurs without limitation by a floral brush.
What is the difference between determinant and indeterminate tomatoes?
Indeterminantnye easy to distinguish from determinant tomatoes before the appearance of flowers and fruits.
When seedlings emerge in 3-4 days, the cotyledon knee expands and the type of the future bush can be indirectly determined by its length. In indeterminate varieties, it is longer (3-5 cm) than determinantal (1-3 cm). However, with a lack of light, the seedling can stretch a lot and then it will be difficult to determine which bush will be. In the photo, a seedling of an inderminant tomato, the semi-nuclear knee is rather long.
When the seedlings reach the age of appearance of the first flower brush, you can easily determine the type of the future bush. Indeterminate tomatoes form the first brush after 8–9 true leaves and above, determinant tomatoes –– after 6–7 true leaves and below. An example of an indeterminate variety is seen in the photo, already 9 true leaves, but not a single flower brush.
When the plant has been planted long ago, it has grown well and has several knotted brushes with fruits, it is difficult to determine the number of leaves before the first ovary, since the seedlings could be buried and part of the stem remained underground.
Indeterminate varieties lay flower through 3 leaves. In determinant tomatoes between tassels there are always less than 3 true leaves.
On a plant of determinant varieties, it is always possible to find an escape, the growth of which ends with the ovary; the indeterminant will not have such a case. The only erroneous adoption of an indeterminate tomato as a determinant can be the case when during the formation of a plant the pinching of the shoot immediately follows the flower brush and it seems that the shoot on it has finished growing. Therefore, it is necessary to be careful and count the leaves between the ovaries as a test.
In the photo you can see how indeterminate varieties grow.
Indeterminate tomatoes are thought to have tall shrubs, and determinant tomatoes form low-growing plants. This statement is partially correct, but there are exceptions.
There are tomatoes for greenhouses, which form tall plants, but are determinant varieties of tomatoes, forming a brush, less than 3 leaves. This is the most modern greenhouse hybrids. There are also stem indeterminantnye tomatoes that have a low-growing shrub, for example, the well-known late-ripening variety Volgograd 5/95.
The scheme of various types of bush is shown in the diagram.
The stem type of the bush is in no way connected with branching, the formation of brushes and has corrugated leaves and a thickened central stem, which keeps the plant in an erect state even with a large number of fruits and does not require a garter. An example of a stem determinant variety of tomatoes, the photo of which is located below, shows how compact this shrub is.
Varieties of determinant tomatoes
The group of determinant tomato varieties is 4 species of plants, which differ in the degree of growth limitation and have their own characteristics:
- Semi-determinant. These tomatoes can often be confused with indeterminantnymi and is an intermediate type of branching plants. They limit their growth after the formation of 10-12 flower brushes, but they are bookmarked every 2 true leaves, but there are also gaps with 3 leaves. Therefore, it is believed that semi-determinant varieties lay the ovary after 2-2.5 leaves. The first flower brush is laid in 7-8 leaves.
- Determinant. In these tomatoes, the formation of brushes occurs strictly less than 3 leaves, and after they have grown 5-6 pieces - the shoot finishes its growth with a floral brush. Bookmark the first peduncle occurs after 6-7 true leaf. In the photo of the determinant varieties of tomatoes, it can be seen that there is no longer a top on the bush after the ovary, and growth continued from the axillary bud at the lower leaf.
- Super determinant. These varieties are precocious. Floral brushes are laid in 1-2 leaves, and after their formation in the amount of 4-5 pieces, a sprout appears, limiting the growth of the plant by the peduncle.
- Supersuper determinant. These include super-dwarf and super-early varieties. They can form 2-3 flower brushes in a row without any gaps from the leaves. Escape restricts its growth after the formation of 3-4 flower stalks. The first brush appears after 5 true sheets and after 1 sheet the next one can form.
Pros and cons of determinant varieties of tomatoes
The positive features include the following:
- early ripeness, as the flower brush is laid through a smaller number of leaves than in the indeterminate ones, the ripening of the first fruit occurs earlier.
- high early yields, because of the laying of the ovary through a smaller number of leaves than indeterminant varieties, then a larger number and efficiency of yield of the crop is higher per meter of stem.
- a more consistent return of the crop than that of the indeterminant varieties, since several brushes are tied almost simultaneously at the same time.
The disadvantages of these tomatoes are as follows:
- less overall yield, since growth is limited to the brushes, the bush can be completely closed and the plant stops growing in height and form new ovaries.
- requires increased mineral nutrition, due to the frequent formation of brushes, more fertilizer is needed to form the crop.
- require less work on the formation of the plant, due to the restriction of growth of the peduncle, it is necessary to remove more stepsons and not to overload the plant with ovaries.
- susceptibility to disease, in a plant that is more loaded with ovaries, and this is the usual condition of determinant varieties, decreases resistance to infections, therefore, an increased use of chemical remedies is required.
Hopefully, the article revealed the features of different types of bush, as well as the pros and cons of determinant tomato varieties.
Diagram of the formation of determinant tomatoes
Formulation of indeterminate tomatoes
Indeterminate Tomato Varieties
Such a term refers to varieties that can grow to quite impressive sizes. That is, the bush can "grow" to the greenhouse ceiling and continue to grow, tying up with all new and new brushes. Otherwise, these varieties are called tall.
Under suitable conditions, indeterminate varieties can grow throughout the year. At the same time on one bush can be up to fifty brushes.
Bloom like varieties begin after 10 sheets appear. The seedling is grown for two months, and the first fruits can be tasted about three and a half months after planting.
Determinant Tomato Varieties
These varieties do not tend to grow endlessly. They are able to form a limited number of brushes (up to eight), after which the growth stops.
Determinant varieties are divided into two groups: medium tall and short stunted.
Standard varieties are low enough and have thickened stems. They mature early enough. The age of seedlings in them reaches 45 days, and fruiting begins in 70-90 days. Standard varieties are given up to three brushes from one bush.
Tomatoes of medium height can grow to a height of one meter. The recommended age of seedlings is about 50 days, the bush begins to bear fruit after 100 days. Such varieties are quite fruitful: 7-8 brushes appear on one bush.
Differences in care for determinant and indeterminate tomatoes
Any gardener will have a logical question: which varieties should be preferred for your plot? The answer depends on what goals you are pursuing and how much strength you intend to invest in caring for plants.
Among the main advantages of indeterminate varieties, the following can be singled out: they can bear fruit for quite a long time. Crop they will give gradually, while with proper care can get up to one bucket of tomatoes from each bush. However, it is necessary to take care of the formation of a bush into a single stalk, regularly eliminating stepchildren and excess foliage. In addition, tomatoes indenominant varieties need to be tied up regularly so that they do not break under their own weight.
Determinant middle-aged tomatoes begin to bear fruit much earlier. They do not need a regular garter: it is enough to tie up the bushes only once. Shrubs are smaller and do not clutter up the greenhouse space. Of course, with proper care, these varieties can give out one bucket from a bush, but you will have to make a lot of effort to do this.
Standard varieties give the first harvest in early summer. Garter bushes are not required, in addition, such tomatoes feel great in pots. Care they require a minimum amount. However, there is a rather significant disadvantage: such varieties will give only one crop, after which they will only decorate your garden plot.
Before you buy one or another brand, ask yourself a few questions. How many tomatoes do you want to get? Are you going to grow them for sale or just to pamper yourself and your family? Do you intend to preserve tomatoes for the winter? It is also necessary to take into account the climate in which the cultivation will take place, as well as the presence or absence of a greenhouse.
In areas with a cold climate, tomatoes are never grown without shelter, and determinant tomatoes are better suited for greenhouses. During the short summer they will be able to give a good harvest. In the middle lane, determinant tomatoes give excellent yield in the open field, and indeterminant ones are recommended to be additionally protected from the cold. In the southern regions in the open field will feel great any variety.
Very important is such a parameter as the age of planting seedlings in the ground. If you want to get an impressive crop, you do not need to sow the seeds at the same time. From the date the seedlings are transplanted into the ground, subtract the recommended age and add the seven days that will be required to germinate the seeds. Remember that if you sow seeds too early, the plant will not be able to get the energy it needs. If you sow tomatoes too late, the plants will not be able to realize their full potential.
What does determinant tomato mean?
What is it expressed in? Growth restriction occurs by the appearance of a floral brush, on which flowers first appear, and then fruits will begin to tie. Further growth will occur from the strong stepson, which will appear from the leaf bosom located immediately under the brush on the top of the bush.
Determinant variety of tomatoes
Determinant tomatoes are also divided into:
- Semi-determinant - includes varieties and hybrids with an intermediate type of branching,
- Super Determinant - this includes a group of early ripening varieties,
- Supersuperterminantnye - this includes super early ripening varieties with dwarf growth.
it tall tomatoes, which should be mechanically limited in growth. Since such a tomato vine grows up to 4 m. Height. But since the warm season is short and the tomatoes above 2 m. The marks do not have time to ripen, then the top is removed at this height.
These are such industrial varieties of tomatoes, which are grown on large areas for further sale or processing of tomatoes. They do not require a garter, have a thick stalk and the first fruits receive on day 75 after the first shoots of seedlings.
Tomatoes of this type are starting to ripen. already at the end of June.
Standard grades are used for industrial cultivation, they are unpretentious
Differences between them
Differences and differences between bushes become noticeable at the stage of growing seedlings. In the indeterminate ones, on the 4th day after peking, the cotyledon knee is clearly visible. Later, when growing a bush, the first ovary of the indeterminate appears above 9 leaves, and the determinant after the 5th leaf plate has the first ovary of a tomato.
Seedlings of determinant varieties in the presence of 5 leaf plates begins to form a floral brush.
Determinate Variety Growth Scheme
The formation of a tomato bush also varies significantly - indeterminate forms in one stem, and determinant varieties in 2-3 stalks.
Which varieties are better
It is difficult to say which varieties are better and which ones are worse. Everyone chooses not only for their taste, but also for the region of growth. It is also important where the tomato will grow in the open field or greenhouse. Therefore, any type can be useful when growing tomatoes.
On one site can grow different types of tomato.
How to distinguish between plants what kind of
Here are examples, disassembled by the type of bush and belonging to the variety. Actually in appearance it is difficult to distinguish which type the bush belongs to. Since it could deepen before planting or pinch escape. But if the gardener himself acquires seeds, then the package will indicate the type tomato plant.
The type of variety is indicated by the manufacturer on the seed package.
If the seeds were obtained from a neighbor in the dacha, then it is necessary to clarify the name and then look on the Internet or in print media to which type this variety belongs.
Indeterminate Tomato Varieties
These are tall tomatoes that reach a height of two to three meters. The first brush of tomato is usually formed above the ninth leaf. Growth can be long depending on weather conditions and usually the top of the bush is pinched in order to keep the fruit set.
In medium-sized regions, this variety is quite popular too. It is grown both in open ground and in greenhouses. Of course, they are suitable for greenhouses and northern regions, but compared with the determinant varieties, the fruits will be later. You can easily guess this sort in your garden or in a greenhouse. This tomato will be the highest, almost resting on the roof of the greenhouse.
The advantages of indeterminate varieties:
- Tomatoes of this variety are very high. Trunks tie up vertically. This allows the plant to increase the number of brushes. That is, from a small area of these tomatoes, you can collect a large number of fruits. The harvest of this variety can give up to sixteen kilograms from one square meter.
- Tomatoes are less susceptible to disease. Tall tomatoes must be tied to the trellis, remove the lower leaves and stepchildren. This gives access to uniform lighting and air circulation.
- The fruiting of these tomatoes lasts longer, unlike the determinant varieties. This allows you to enjoy the harvest from July to the first frost.
- The variety is quite easy to maintain. It will be enough for you to form it. You just need to leave one stalk and remove the stepsons.
- It is more convenient to work with the plant and harvest, standing, and not in the pose of a summer resident.
Disadvantages of indeterminate varieties:
- It is necessary to have supports for the plant. Otherwise, it will lie on the damp ground, which will lead to the decay of the fruit.
- Fruit ripening takes longer. This variety requires a long summer period or additional lighting and heating.
- Needle staking. It is necessary to constantly remove stepchildren on the plant so that they do not overload it.
Advantages of determinant varieties:
- These varieties of tomatoes are one of the earliest.
- Not very picky in the garter. A single tying is enough, and some tomatoes of this variety do not require a garter at all.
- Grade unlike indeterminant more compact. They do not create a "jungle" in the greenhouse.
- The variety is widespread and very popular.
- Fruit ripening happens more amicably. This variety is suitable for mass preservation.
- The best grade for northern regions. Выращивая этот вид томатов в тепличных условиях, можно получить быстрый и большой урожай. Успевает отдать урожай и в открытом грунте в условиях короткого лета.
Недостатки детерминантных сортов:
- Меньшая урожайность. На растении формируется несколько кистей, и оно прекращает свой рост. After the fruit ripens, if the plant is still completely green, it will have to be removed. May continue to form the crop on the stepsons.
- We need more mineral fertilizers, as new brushes are constantly being formed.
- Fruits of different sizes. The first ones are larger, the next smaller, but for personal consumption it is an insignificant disadvantage.
The choice of varieties of indeterminate tomatoes is huge:
Large selection of different varieties in the article "The best varieties of tomato with photos and descriptions". Many tall varieties in the article - "Tomato varieties for polycarbonate greenhouses"
- «Wonder of the earth"- it is an early ripe grade. It grows up to two meters. Productivity to four kilograms. Fruits are heart-shaped, weighing about half a kilogram. Differs drought tolerance. Fruits do not crack, transportable. Variety corresponds to its name.
- «Christina Plume"- tomato type tiger cream. The plant grows to a height of two meters. With one bush with good care, you can collect up to eight kilograms of tomatoes. It has a sweet taste and high yield.
- «Cherokee»This variety is very popular. But one brush ripen to eight fruits. This variety has an excellent presentation. Fruits keep their shape, do not crack.
- «Star gold"- This is a miniature fruit to thirty grams. The variety is distinguished by its unpretentious, golden shade of the fruit and sweet taste.
Crop determinant varieties:
- «Rocket»Elongated oval tomatoes. Fruit weight ranges from sixty to one hundred grams. Bushes of this variety are compact. Six to seven bushes can be planted on one square meter.
- «Nevsky»Tomato. One of the earliest bushes. The form is flat-round. Color is light red. Tomato weight up to fifty grams.
- TomatoWhite filling". The variety is very juicy, weighing up to one hundred thirty grams.
When considering all of the above, you can determine which variety is best for you. Think about why you need tomatoes. Just pamper yourself or for canning?
If you decide in your garden to grow both determinant and indeterminate varieties of seeds, then you should pay attention to the sowing of seeds. Indeterminate varieties ripen longer. Tall seedlings are recommended to be planted in the ground on the sixtieth day. Therefore, when sowing seeds for seedlings, first indeterminant varieties are sown, and after two weeks you can start sowing determinant varieties.
How to distinguish which sort of plants
If you suddenly mixed two varieties when soaking seeds for sowing, do not worry. At emergence of shoots in three-four days the seed-bearing knee of a seedling is straightened. You can easily distinguish varieties by its length.
In indeterminate varieties, the knee is longer about three to five centimeters. Determinant variety will be about a centimeter. When diving tomatoes, you can correct the situation by planting different varieties in different boxes.
Choosing a variety of tomatoes for planting
Even when choosing a variety, you need to take into account your climate zone and growing conditions. Will it be open ground or greenhouse.
If you live in the northern regions, you can use determinant varieties grown in greenhouses. They ripen quickly and have time for a short summer to bring you a harvest.
In the middle lane, you can grow determinant varieties in open ground and indeterminate in a protected.
Both varieties will feel great in the southern regions.
Therefore, make a choice in favor of the desired variety. Now you know the differences between determinant and indeterminate tomato varieties well. Good harvest.
Determinant Tomato Varieties planted in early April. Seedlings are grown in wooden boxes. When the second and third leaves, the plant is transferred to the greenhouse.
Feed tomatoes with different types of slurry in small quantities. It is necessary to form plants only in special conditions with optimum indicators of humidity and temperature. Despite the fact that determinant tomatoes are unpretentious, the soil for them is of great importance, especially in the early stages of growth.
Before planting, the soil is treated with water with bleach. A good option would be the soil on which cucumbers were previously grown. To do this, remove the top ten centimeter soil layer and lay cucumber soil. Hay and compost are laid on top with a layer of fifteen centimeters.
Good conditions for growing determinant tomatoes can be created with burnt out between two layers of hay. Every year, the soil should be updated, add layers of hay and carrying out protective spraying from insects.
In no case should manure be added to the soil. This can lead to the process of fattening plants. If the leaves are thick, the ovaries will become smaller and the yield will decrease.
In the fall, superphosphates, lime and ash must be added to the soil.
Planting in the greenhouse
It is possible to plant tomatoes in a greenhouse in different ways, thanks to the flexibility and easy survival of this crop.
A non-primal stepchild can take root immediately, even without the necessary care. In the case of the planting of determinant middle-grown tomato crops in the greenhouse, they can regulate their own growth. On the main runaway, in the process of the formation of four or five inflorescences, they are punched and growth stops. The branch part is laid after the sixth leaflet.
The plant is originally grown in pots with sufficient space for the full development of the roots. Various varieties can be planted not only in the wells, but also in the furrows to a depth of 15-17 cm, leaving a tip with two to four leaves on the surface.
The appearance of the crop on the determinant plants has a cyclical dynamics. The first, the earliest fruits appear on the main shoots, then the growth of tomatoes continues on the side stems. Limiting on the main shoot the growth of tomatoes, reduce the period of fruiting plants.
This technique is used for determinant varieties in the open field. The formation of tomatoes depends on certain factors. It:
- regional weather conditions
- cultivation target
- type of cultivation facilities.
Proper formation is necessary for better pollination of flowers, for fruit binding and increasing yields. Tomatoma is characterized by the presence of lateral shoots. Each shoot is an additional stem bearing fruit. However, if the plant will give a lot of power to the stepsons, the fruit will linger and yield will decrease.
On this basis, in order to grow a good crop, the bushes should be properly shaped. Formation is carried out taking into account the characteristics of a particular variety.
Compact low bush will bring good results. For ultra-ripe tomatoes no shaping needed. But for highly superdeterminant varieties, the formation is very important. Breaking the side shoots should be once a week.
Single-stem tomatoes on the vine will produce fruits 2 times more than the bush. Therefore, these plants, forming a single stalk should be planted as often as possible. For tomatoes growing more intensively, the formation of two stems. In such cases, stepchildren growing from the leaf axes, located under and above the first inflorescence, are left. After the 8th inflorescence appears, the growth point is pinched.
Gardeners get the smallest yield from a single plant when they form one stem without a pin. Other methods include the availability of intermediate variants with different ripening terms. Forming bushes, you need to consider that the smaller the number of stems, the thicker the planting.
Protection against diseases and pests
To protect the plant from fungal infections and other diseases, special preparations are used: "Ridomil Gold", "Infinito", "Tattu", "Alette".
One of the most dangerous diseases for tomatoes is top rot. It causes blackening of the tops of plants. Struggling with the disease, splashing the seedlings while planting calcium nitrate.
From insects for tomatoes dangerous pests: winter scoop, Colorado potato beetle and aphid. The remedies for these pests are: “Act ovit”, “Fitoverm” “Confidor”. To get rid of aphids, in place of its accumulation send a strong jet of water and wipe the leaves with ash.
What is included in the concept of determinant variety
Determinant is a concept from linear algebra. Its literal translation means "determinant".
As applied to plants, the name determinant means - defined. ROst plants stop with the appearance at the top of the flower brush.
For gardeners who do not aspire to the industrial scale of growing tomatoes, they want an early harvest - determinant tomatoes are an ideal choice.
If the task is to get as many fruits as possible - the choice is for indeterminate (unlimited in growth) varieties.

The main differences between the determinant and indeterminate and other tomatoes
Sometimes sellers of seeds indicate in annotations: short, medium tall or tall. Such a definition is erroneous and misleading inexperienced gardeners. Among indeterminantny grades there are undersized. Determinant tomatoes, bred specifically for growing in greenhouses, have a high stem.
The main difference is not the height of the plant, but its development during the formation of floral brushes. Indeterminate tomatoes grow up and bear fruit throughout the season. Determinants have a peculiarity of stopping in growth with the formation of a certain number of inflorescences.
What is the difference between seeds
When selecting seeds should pay attention to the manufacturer's instructions - a pure variety or a hybrid.
Preference should be given to hybrids. They have high yield and early maturity, resistance to diseases.
Better adapt to changes in climatic conditions. The most important thing is to determine the time of sowing.
In different regions, planting seeds is carried out at different times. For middle band sowing time:
- indeterminate tomatoes - early march,
- semi-determinant - mid-March,
- determinant - the end of March.
The difference in seedlings
Of great importance is the age of seedlings.
Determinant varieties are planted in a permanent place for 55-60 days after sowing. Non-determinant ready for landing later - after 65–75 days.
The type of future bush is determined by seedlings. On the determinant brush is tied with the appearance of the 5th or 6th leaf, on the indeterminant after 8-10. Some varieties of determinant tomatoes can be planted, bypassing the seedling stage directly into the ground.
Due to the fact that this species has mixed properties, it is sometimes confused with indeterminant varieties. Height from 1.5 to 2 m allows more efficient use of the area of greenhouses, Garter is required to do.
The first inflorescence appears after 7-8 leaves on the main stem and 3-5 on the lateral. The brushes are usually fastened from 10 to 12, after which the central stem stops growing. The following brushes are laid in 2, rarely - 3 sheets.
Advantages of this type: high resistance to diseases, yield and excellent quality of the fruit.
Semi-determinant varieties and hybrids are intended mainly for growing in greenhouses. Find out which varieties are suitable for greenhouses.
Early and ultra-early dwarf varieties with a strong stem. Lay 2-3 inflorescences, without waiting for the intermediate leaves. The first brush may appear after 3 sheets.
3-4 brushes are formed, then the growth stops. Height 30-35cm. The formation of the bush is not required. Usually planted in open ground. Care is minimal.
One of the most unpretentious and tasty medium-sized large-fruited varieties. Attractive shape, crimson color. Fruits are stored for a long time and ripen well. Tall Grown in a greenhouse and open ground. Resistant to frost. Not self pollinated.
The unpretentious, checked and reliable mid-season grade. The sweet fruits of the classic heart-shaped form, when ripe, are colored orange. Easily tolerates temperature extremes. Tall, requires a garter to support. When grown in open ground, most of the fruits ripen on the vine. From fruits get very tasty juice.
Promising early ripe determinant variety. Fruits are large dark red. Tastes excellent. Requires garters and pinching to increase the size of the fruit and accelerate fruiting.
Medium early variety. In the open field is recommended cultivation in the southern regions. Bush compact, medium-branched. Resistant to overheating and mechanical damage. Used for canning and getting juice. Fruits are medium orange-red. No staving and garter required. Resistant to gall nematode.
Hybrid for open ground and light greenhouses. Mid-season, tall. Resistant to diseases and temperature extremes. Under any weather conditions gives a lot of fruit. Shade tolerant Red medium sized fruits are stored for up to 2 months. Garter and bush formation are required.
For open ground
Very early, 30-60 cm high. The fruit is round, slightly ribbed red. Resistant to cracking. It develops well and bears fruit in low light and low temperature. More about tomato "Sanka"
Can be planted directly into the ground, bypassing the seedling stage. In the south, the fruits ripen in early summer, in the north - in mid-July. The period from disembarkation to maturation is 85 days. The variety is resistant to diseases. Fruits do not tolerate transportation.
"Superbomb" Mid-season novelty for open ground. Resistant to weather changes. Requires enhanced feeding and pinching. Fruits are large, fleshy 5-6 per brush. Gives in open ground a decent harvest.
A fruitful perspective early grade (vegetation of 85 days). Resistant to late blight, powdery mildew. Fruits are large, good taste, resistance to cracking. Universal in use.
The main crop of determinant tomatoes is the fruits of the first 3 inflorescences. For speeding up ripening, small stepchildren break off and pinch shoots.
When forming a bush, 1-2 side shoots are left near the main stem and tied under the first brush. 3-4 brushes are left on the central stem. On the side of the shoot form 3 brush, after which it pinch.
In the future, to continue the growing season form new shoots. In this case, timely feeding is necessary.
Planting and care
After the appearance of the second or third leaf planted in a permanent place. The soil by this time should warm up at least 15 degrees C.
Care is as follows:
- burying, tying, if the variety requires it,
- weed removal:
- loosening the land
- watering under the root of the bush, mulching,
- fertilizer, hilling,
- prevention and control of diseases and pests.
Possible mistakes when growing
- Planting varieties for greenhouses in open ground and vice versa.
- Wrong watering.
- When forming a bush, it was not the right time to hold the pinch and pinch the tops.
- Ignoring disease prevention.
- Formation of uneven ovaries, demolition of the bush under the weight, late blight of tomatoes, due to the fact that the bush is incorrectly tied.
- Growing in unventilated greenhouses leads to cessation of pollination, empty flowers. At temperatures above +33 degrees, tomato pollen becomes sterile, and fruit set up does not occur. Non-self-pollinated varieties of ovaries do not give.
- Too thick landing.
- Excess top dressing.
Whether or not to grow determinant varieties depends on what kind of result is needed.
