Indeterminate tomatoes: characteristic features, common varieties, nuances of cultivation


Almost every gardener grows tomatoes on his own personal plot, if the climate allows it. But often it is quite difficult to choose a specific variety or hybrid without getting confused in the variety of varieties bred by breeders. Many of the tomatoes belong to the category of indeterminate, that is, not restricted in growth. They have certain advantages, but they are not devoid of disadvantages. It is advisable to familiarize yourself with these characteristic features in advance so that the choice is deliberate.

Indeterminate tomato variety - what is it?

The main feature that distinguishes indeterminate tomatoes from determinant ones is the growth of the stem during the entire season of active growing season. When cultivated in a climate suitable for a plant, it can stretch up to 4 m in height, in less suitable conditions its length reaches 2 m.And it is also characterized by the presence of a powerful developed root system and the active formation of a green mass. There is a growing point at the top of the stem, not a flower brush, therefore, upon reaching the desired height, it is usually pinched, limiting further growth.

The main feature of indeterminate tomatoes is unlimited stem growth

A long period of fruiting is also characteristic of them. If these varieties are planted in heated greenhouses, the plants yield a harvest throughout the year and even more, forming 40-50 brushes during this time (and this is not the limit!).

Indeterminate tomatoes ripen 30–35 days later than determinant ones. Accordingly, such varieties are best suited for southern regions with a subtropical climate. There they can be planted both outdoors and indoors. In central Russia, it is advisable to cultivate these varieties in greenhouses, and in regions where the summer is very short and cool, not to plant them at all.

Fruit clusters in indeterminate tomatoes are formed along the entire length of the stem, respectively, this has a positive effect on yield

It is possible to distinguish indeterminate tomatoes from determinant ones already at the stage of growing seedlings:

  • when the seedling of the indeterminate type straightens, an elongated cotyledonous knee is visible (the place below the cotyledonous leaves, sometimes it is called the subcotyledonous knee) - up to 3-5 cm instead of 1-3 cm. Further, as the plant develops, the first flower clusters are formed at the level of the 9-12th sheet, the interval between them is 3 sheets or more;
  • in determinant varieties, fruits begin to form lower, the distance between them is less. Sometimes several brushes are formed at once in one axil of the leaf.

Contrary to popular belief, not all indeterminate tomatoes are tall, and determinant ones are short. This is true in most cases, but there are exceptions. There are determinant hybrids with a stem reaching a height of about 2 m, as well as low indeterminate varieties that can be classified as standard. Standard tomatoes are distinguished by the presence of a very powerful stem. Both determinant and indeterminate varieties can have such a feature. But if in the former the trunk can easily withstand the severity of the harvest, then the latter still need support.

Advantages and disadvantages of indeterminate varieties

Like any plant, indeterminate tomatoes have their pros and cons.

Dignity

These varieties are characterized by a long fruiting period and, as a result, a high yield (the yield rate for them is about 14-17 kg / m²). Tomatoes in the open field continue to ripen until the first frost, in greenhouses - until the end of September or even until October. The experience of gardeners shows that from 10 bushes of indeterminate varieties and hybrids, 2-3 times more fruits can be removed than from 20 bushes of determinant tomatoes.

Provided that proper pruning is carried out, the bushes take up very little space. However, unlike determinate varieties, they are not suitable for balcony or home cultivation.

Plants that are not overloaded with fruit clusters have better immunity than determinate tomatoes, which often suffer from fungal diseases, unless they have genetic protection. And they are also less sensitive to growing conditions - they do not pay special attention to temperature changes, drought or an abundance of precipitation, heat.

Disadvantages

Indeterminate tomatoes also have disadvantages. From the gardener throughout the growing season, competent agricultural technology will be required, especially with regard to the formation of plants. Tall bushes must be tied along the entire length of the stem. Accordingly, a trellis or other type of support will be needed. Plants need to provide uniform lighting and good aeration.

If the bushes of indeterminate tomatoes are not tied to a support, you can not count on a large harvest - the fruits simply will not have enough heat and light

The harvest ripens much later than that of determinant varieties, by a month or even more. Therefore, when deciding to plant such varieties or hybrids in the open field, be sure to take into account the peculiarities of the climate in the region and choose the right variety. Among the early indeterminate varieties are:

  • Alkor F1 - ripens on the 106th day from germination;
  • Andryushka F1 - ripens on the 95th day from germination;
  • Diana F1 - ripens 90-100 days from germination.

If the summer is unfortunate in terms of weather, the harvest may not wait at all.

The nuances of culture care

Indeterminate tomatoes require a certain method of placement in the greenhouse and constant maintenance.

Location in a greenhouse or garden bed

High productivity in indeterminate tomatoes is impossible if you do not engage in bush formation throughout the season. If you regularly pay attention to pruning, you can greatly save space in the greenhouse, planting one plant even 30 cm². However, it is still recommended to provide the bushes with a large area for food.

It is most convenient to place them in a checkerboard pattern, in two rows. The optimal distance between tomatoes is 45-50 cm, row spacing is 65-75 cm. However, there are also varieties with especially powerful bushes - the so-called tomato trees, or standard tomatoes. In this case, the spacing between plants is at least 80–90 cm, and between rows - 1–1.2 m.

When planting standard tomatoes, the interval between plants is at least 80-90 cm

The height of the greenhouse in which the bushes are planted must be at least 2 m. Otherwise, the plants will become cramped already at an early stage of development, which, in turn, will negatively affect the yield.

Upon reaching a height of 45-50 cm, the bushes begin to tie up. The support must be strong enough and securely fixed, because the total weight of the crop is quite significant. You cannot use thin wire or twine for tying - the stems are cut or frayed.

Removing stepchildren

Throughout the growing season, indeterminate tomatoes regularly, once every 10–12 days, remove the shoots that grow in the leaf axils - stepchildren. If they have not yet reached a length of 5–7 cm, they can simply be broken out. Otherwise, they are cut with sharp scissors as close to the growth point as possible. This is a mandatory procedure, otherwise the greenhouse will quickly turn into something resembling impenetrable thickets in the jungle, and very few fruits will grow on the bushes overloaded with green mass - they simply will not have enough food.

Tomato's stepson is a lateral shoot that forms in the leaf axil

Bush formation

Formation can be carried out in two ways:

  • in one stem;
  • steps.

The easiest way to form a bush is in one stem. It is as follows:

  • all forming stepchildren and lateral shoots are regularly removed, leaving only the central trunk and fruit brushes;
  • cut off all the leaves below the first bunch of tomatoes. But you should not be zealous with this - a maximum of three sheets are removed at a time;
  • when grown outdoors at the end of July or in the first half of August (depending on the climate in the region), the stem is pinched so that the already formed tomatoes have time to ripen before frost.

When properly formed into one stem, tomatoes take up very little space.

Experienced gardeners also advise removing the two lowest brushes when forming the first inflorescences. Practice shows that tomatoes of most varieties ripen on them for a very long time. Getting rid of them in time, you can increase the number of fruit ovaries and accelerate the ripening process of tomatoes located higher on the stem.

The step formation is somewhat more complicated. It is carried out in this way:

  1. During the active growing season, the main shoot is replaced by a lateral stepchild several times. For the first time, the stepson is left in the bosom of the fourth or fifth leaf, choosing the most developed one.
  2. As soon as the fruits are tied on the lateral shoot, the main stem is pinched, leaving 2-3 leaves above the last brush.
  3. After that, the stepson begins to lead as the main escape.
  4. If he reaches the ceiling of the greenhouse, somewhere in the lower third of his stem, one more stepson can be saved by pinching the new mother shoot too.

Indeterminate tomatoes can be formed in two ways: in one stem and in two stems

It is much easier to form tomatoes into one stem, but step pruning can significantly increase yields and extend the fruiting period

Any mechanical damage is a gateway for all kinds of infections. To minimize the risk of infection, it is advisable to carry out the procedure early in the morning and leave small stumps 2-3 mm in height, which have time to dry out in a day. All used instruments and wounds must be washed with 1% potassium permanganate solution or other suitable disinfectant. If the leaves and stepchildren break off with their hands, care must be taken not to damage the skin on the stem. It is best to bend side shoots to the side, leaf plates down.

Indeterminate tomato varieties

There are many varieties and hybrids of indeterminate tomatoes. Some of them have already been tested by time and several generations of gardeners. Breeding novelties are constantly available in the public domain. All of them have certain advantages, but not without disadvantages. Accordingly, you need to familiarize yourself with the description in advance so that there are no surprises during cultivation.

Indoor

In greenhouses, indeterminate tomatoes are most often cultivated in central Russia, as well as in the Urals, Siberia, and the Far East. This allows you to provide the required temperature regime. We must not forget that the room will have to be regularly ventilated, the stale humid air is a very suitable microclimate for the development of many diseases.

Angel F1

One of the relatively new domestic hybrids. There are no restrictions on the growing region in the State Register of Breeding Achievements of the Russian Federation. Ripening early, according to the purpose of the fruit - salad. The harvest ripens in 95-105 days.

The fruits are almost round, regular in shape. The average weight is 150–170 g. The peel is uniformly red, even the typical yellowish-orange spot at the stalk, typical for most varieties, is absent. The pulp is firm, but juicy. The yield is very good - up to 19.9 kg / m².

Tomatoes Angel F1 - very presentable fruits, distinguished by excellent taste

The hybrid is characterized by the presence of immunity to fusarium and verticillosis, but it is often affected by apical rot.

Diana F1

Another Russian hybrid, in the State Register of Breeding Achievements of the Russian Federation - since 2010. Suitable for growing in any region where gardening is possible. The crop ripens early, in 90-100 days. The bushes are quite powerful, but they cannot be called densely leafy.

Fruits are spherical or slightly flattened, with slightly protruding ribs at the stalk, medium in size, weighing about 128 g. The skin is bright pink, firm, but not coarse. This leads to very good transportability. The taste is excellent.

Tomatoes Diana F1, due to their good transportability, are in demand not only by amateur gardeners, but also by professional farmers.

The yield cannot be called a record high - it is 17.9 kg / m².

Icarus F1

Medium ripening hybrid. The crop can be removed 98–110 days after the first germination. The State Register of Breeding Achievements of the Russian Federation is recognized as suitable for cultivation throughout the territory of the Russian Federation. Possesses innate immunity to fusarium and tobacco mosaic virus. He suffers from other diseases typical of the culture quite rarely. And also the hybrid firmly tolerates the vagaries of the weather - drought, waterlogging, low temperatures. Not too many stepsons are formed on the bush.

Fruits are noticeably flattened from the sides, similar to plums, with a dense glossy skin. Even fully ripe tomatoes retain a pale light green spot at the base of the stalk. Fruit weight - 130–150 g. The pulp is very fleshy, there are few seeds.

There are not too many stepchildren on the bushes of Icarus F1 tomatoes

The purpose is universal - tomatoes are suitable both for fresh consumption and for home canning, including whole-fruit. The yield for an indeterminate variety is rather low - 10-12 kg / m², but the taste is excellent.

Belfast F1

A very popular worldwide hybrid from the Netherlands. It entered the State Register of Breeding Achievements of the Russian Federation in 2014. In terms of ripening, it is early ripe: the crop is harvested 90–100 days after germination or 55–60 days after planting the seedlings in a permanent place.

The plant is powerful, but the foliage is medium. Its height is limited to 1.5–2 m. The first fruits on the lower clusters ripen rather quickly, which is, in principle, not typical for indeterminate varieties. The bushes are immune to cladosporium, fusarium, verticillosis, tobacco mosaic virus, but all types of nematodes have a special love for the hybrid.

The tomatoes are in the shape of an almost regular ball. The ribs at the stalk are almost invisible. The flesh is not particularly dense, but thanks to the harsh skin, the hybrid has good keeping quality, it tolerates transportation well. Fruits rarely crack. The presence of many cameras is characteristic. The average fruit weight is 208 g, some specimens reach 300 g.

Tomatoes Belfast F1, very popular all over the world, quickly fell in love with Russian gardeners.

The yield is high - 26.2 kg / m². This indicator is little affected by the weather, including low temperature and lack of light.

F1 chart

One of the novelties of the selection, the hybrid was bred in the Netherlands. In terms of ripening, it belongs to the early ripening: the fruits are removed after 100-105 days. Productivity - up to 4.5 kg per plant.

The fruits are of the correct spherical shape, the ribs do not always appear, in any case they can be distinguished only at the stalk. One tomato weighs on average 180–230 g. The taste is excellent, with a slight refreshing sourness. An almost complete absence of non-marketable fruits is characteristic, the percentage of rejects is only 0.5%.

Tomatoes Diagram F1 almost always look very presentable, the percentage of substandard fruits is minimal

The bushes can be recognized by their unusually long, light green leaves. The variety cannot be called vigorous; internodes for an indeterminate tomato are unusually short. From their creators, these plants have gained immunity to the tobacco mosaic virus, a fungus that causes brown spot. Relatively rarely, they are affected by verticillium, fusarium, root rot.

Pink Paradise F1

A hybrid originally from France, it was included in the State Register of Breeding Achievements of the Russian Federation in 2007. In terms of ripening, it belongs to the mid-season. Fruiting in 110-120 days after germination or 70-75 days after transplanting. You can count on 3.9 kg of fruit per bush. Characterized by the presence of immunity to verticillosis, fusarium, tobacco mosaic virus.

Tomatoes are flattened, slightly ribbed. The skin is glossy, bright pink. The pulp is very dense, high in sugars, the seeds are almost invisible. The average weight of the fruit is 125–140 g, some specimens reach 200 g. The taste is excellent - a variety from the category of gourmet foods. However, almost all pink tomatoes are distinguished by their wonderful taste.

Tomatoes Pink Paradise F1, like all pink tomatoes, have excellent taste.

The height of the bush is about 2 m, it is densely leafy, it is imperative that you regularly pay attention to pruning. Sometimes it is formed into two stems - in this case, the first fruits will have to wait 12-15 days longer, but the yield will increase. The hybrid tolerates a short-term drop in temperature and its drops well. The fruits are characterized by very good transportability and keeping quality, they hardly crack, although the skin is thin, even tender. Suitable for making juice and puree - they turn out to be very thick, with an unusual raspberry hue.

Shannon F1

Another popular Dutch hybrid. Russian gardeners met him in 2003. The State Register of Breeding Achievements of the Russian Federation does not give recommendations regarding the growing region, but practice shows that it manifests itself best in warm southern regions. Medium ripening hybrid. The harvest ripens in 98-110 days.

The fruits are rather small, weighing an average of 107 g, some specimens - 160-180 g, in a bunch of 6-8 pieces. The shape is correct, rounded. The ribs are almost invisible. Taste qualities of ripe tomatoes are excellent. Keeping quality is also very good, even at room temperature the fruits will lie for at least three weeks.

Shannon F1 tomatoes in Russia are best planted in regions with a warm subtropical climate

The variety belongs to the category of indeterminate, but the first fruit cluster is formed low, already above the seventh leaf. The hybrid tolerates heat and drought very well, it is immune to verticillium, fusarium, brown spot, mosaic virus.

Cherokee

The variety is originally from the USA, at home it is one of the most common. Bred in the 19th century. It is appreciated for its consistently high yield, excellent taste and the presence of a very good (although not absolute) immunity to diseases typical of the culture. In terms of ripening, it belongs to the medium early, it takes 110-115 days to ripen the crop. You can count on 4 kg per bush.

The height of the bush is usually limited to 1.2–2 m, it is usually formed in 2-3 stems. On each plant, up to 8 fruit clusters ripen, they have an average of 10 tomatoes, shaped like a heart. Their color is very unusual: in addition to the usual dull red color, the presence of a subtone is also characteristic - yellowish, purple, violet, chocolate. Sometimes it does not appear over the entire surface of the fruit, but in separate irregularly shaped spots.

The fruits are multi-chambered, the average weight is about 250 g, but depending on the growing conditions, it can vary from 150 g to 500 g. The pulp is very fleshy, juicy, sweetish, with an unusual smoky aroma. The skin hardly cracks.

Cherokee tomatoes look very unusual, but this has not scared off several generations of gardeners.

For open ground

When grown outdoors, indeterminate tomatoes will definitely need a support - a trellis or a net. The stems will have to be tied to it along the entire length. In the open field, these varieties can only be planted where the climate for gardening is more or less suitable, that is, in areas with a sufficiently long and warm summer.

Watermelon

Achievement of Russian breeders, in the State Register of Breeding Achievements of the Russian Federation - since 2004. Variety from the category of medium early: the harvest ripens in 107-113 days. The height of the bush without pinching exceeds 2 m. Thick foliage is characteristic. Plants are relatively rarely affected by late blight.

The fruits are flattened, the skin is glossy, smooth. Tomatoes are almost one-dimensional. The shape is rounded, with a pronounced ribbing at the peduncle. The yield is not bad - 4.2–5.6 kg per bush. The average weight of a tomato is 98–104 g, subject to competent agricultural technology, it reaches 550 g. The skin is very thin, the fruits are prone to cracking. The keeping quality and transportability of this variety is low.

Unripe tomatoes of the Watermelon variety are slightly similar to watermelon

The variety owes its name to the type of fruit in the ripening process. In addition to the usual dark green spot at the stalk on the skin of a salad color, longitudinal blurred stripes of the same shade are also clearly distinguishable. In mature tomatoes, they change color to brick or reddish brown, blotches of the same tone are visible on the cut in the pulp.

Cardinal

The variety has been listed in the State Register of Breeding Achievements of the Russian Federation for 20 years. In terms of ripening, it belongs to the middle late: the crop is harvested 120 days after germination. The variety is valued for its high resistance to late blight and consistently high yield, which is little affected by the vagaries of the weather. A tAlso, excellent germination of seeds is noted, including those collected independently.

Fruits are heart-shaped, with ribs clearly visible at the peduncle, in each cluster there are 5-7 pieces. At the top there is a characteristic spout. The skin is pink-raspberry, matte. The average weight of a tomato is 440 g, the very first fruits gain weight up to 850 g. The pulp is very juicy, sweet, with a slight sourness. The skin is firm but not hard. Productivity - 7.2–8.4 kg per bush and about 16 kg / m².

Cardinal tomatoes consistently yield crops no matter how lucky the gardener is with the summer weather.

Belongs to the category of semi-determinant, but differs in unlimited stem growth. The first fruit cluster is formed above the eighth-ninth leaves, the next - with an interval of 1-2 leaves. The bush does not branch very readily, the foliage is weak. It is recommended to stop its growth when it reaches a height of about 2 m.

Honey saved

A very popular variety among Russian gardeners. In the State Register of Breeding Achievements of the Russian Federation since 2006. Cultivated without restrictions regarding the growing region. In terms of ripening, it belongs to the mid-season: the first fruits are removed 110-115 days after germination. The variety is appreciated both for its excellent taste and for its unpretentiousness to growing conditions. Shrubs tolerate heat and drought well. Their height, as a rule, is limited at the level of 1.5–1.8 m. The presence of high resistance to phytophthora, gray rot, and the mosaic virus is characteristic.

The shape of the fruit varies from regular and round to kidney-shaped and cordate, the skin is smooth, glossy. Ripe tomatoes are colored in a beautiful golden orange or amber honey color. Sometimes, where the sun fell on them, a pinkish undertone appears. The pulp is sugary, very tender, sweet, with a subtle sourness and a light honey aroma. These fruits are not suitable for canning. There are very few seeds. The average weight of the fetus is 160-220 g.

Tomatoes Honey Spas - one of the most popular yellow-fruited varieties in Russia

The yield reaches 5.6 kg per bush, but only when planted in a suitable fertile soil. The fruits do not crack, they have a very good keeping quality and transportability.

Like other yellow tomatoes, this variety is characterized by a high content of beta-carotene and lycopene, and causes allergies much less often than classic red tomatoes. Such fruits can also be introduced into the children's diet.

Japanese crab

Despite the name, the variety was bred in Siberia and specially adapted to the climatic features of this region, although the State Register of Breeding Achievements of the Russian Federation does not give any restrictions on this criterion. In Siberia, it manages to give a crop even when planted with seeds in open ground. The variety has an innate immunity to root and apical rot, the tobacco mosaic virus. It is recommended to form bushes into one or two stems, pinching them when they reach a height of 1.5 m. They have very active stepsonding.

Fruits are noticeably flattened with pronounced ribs. The skin is dense, but not hard, pink-red or crimson, the stalk retains a dark spot. The pulp is dense, very fleshy, almost without juice, with a pronounced aroma. The fruits are ideal for making ketchup or tomato paste, and retain their attractive appearance in salads for a long time. The average weight of one tomato is 250-350 g, some specimens reach 900 g.

Japanese crab tomatoes are specially zoned for cultivation in Siberia

Productivity - up to 15 kg / m² and about 5-6 kg per bush.

De Barao

A variety bred in Brazil. It entered the Russian State Register of Breeding Achievements in 2000. It can be grown in any regions suitable for gardening. The height of the bush without pinching reaches 4 m. In terms of ripening, it belongs to late ripening. The fruiting period stretches for about 3 months, begins 115–125 days after germination. Accordingly, it is recommended to plant these tomatoes a week and a half earlier than other varieties.

Classic tomato De Barao became the parent of a whole group of varieties

Plants are immune to late blight at the genetic level; they rarely suffer from other diseases. The yield is very high even when grown outdoors (25 kg / m² or more), and in a greenhouse this figure rises to 40 kg / m². At the same time, experienced gardeners noticed that when planting a number of other varieties of tomatoes, it significantly decreases. The variety tolerates heat and cold well, as well as a lack of light.

A whole series of varieties has been developed on the basis of the classic De Barao red tomato. Now in Russia you can find De Barao gold (the most productive - up to 7 kg of fruits per bush), orange (with a high content of carotenoids), pink (less productive, but very tasty), black (with very dense pulp, almost complete absence of seeds and juice) and royal. The latter is a novelty of breeding; it was recently included in the State Register of Breeding Achievements of the Russian Federation. It has improved taste and bears fruit until late autumn.

Fruits are elongated, plum-shaped, on a brush of 8-9 pieces. The pulp is very firm, fleshy. Weight ranges from 30–40 to 100 g. Tomatoes are ideal for home canning. They do not crack in cans, retain their shape and brightness. But you won't be able to squeeze juice out of them.

Miracle of the earth

Sometimes it is called the Wonder of the World. Included in the State Register of Breeding Achievements of the Russian Federation in 2006, no restrictions on the region of cultivation are indicated. The ripening time of the crop is average. The yield is not bad - 13.9 kg / m². The height of the bush is 2 m or more. The variety exhibits a certain plasticity, successfully adapting to weather conditions that are far from optimal. These tomatoes crack very rarely.

Fruits are round or domed, with weak ribs. The skin is deep raspberry hue. A very low percentage of rejected fruits of a non-marketable type is characteristic - no more than 2%. The average weight of a tomato is 380 g, individual specimens - up to 700 g. On the brush, 5–6 of them are formed, one bush gives 8–10 bunches. The pulp is homogeneous, very tender, literally melting in the mouth, granular on the cut, reminiscent of a watermelon.

Tomatoes Wonder of the Earth successfully adapt to far from optimal weather conditions

The record holder is officially registered - the Miracle of the Earth tomato weighing 1200 g. To grow such a fruit, in the lowest brush you need to remove all the flowers, leaving only one. All forming flower buds are cut off, the plant is well watered, and top dressing is applied on time. A single hand must be tied to a support.

The variety is suitable mainly for fresh consumption, the keeping quality is very low. These tomatoes are also good in blanks, suitable for the preparation of tomato paste, juices.

Typhoon

The variety has been listed in the State Register of Breeding Achievements of the Russian Federation since 1997, its cultivation in the Black Sea region is recommended. However, in other regions it shows itself well, especially in central Russia. The harvest ripens in 99-117 days after germination - this tomato is considered early. Possesses innate immunity to cladosporium, Alternaria, tobacco mosaic virus. Does not make high demands on the quality of the soil substrate.

Fruits are regular in shape, almost round or slightly flattened. Average weight - 34–57 g. The first tomatoes on the lowest bunch can reach a mass of 80–100 g. The taste is very good, sweetish. They make excellent juice. The fruits cannot boast of keeping quality and transportability. The pulp is rather loose, so when canning tomatoes often turn into an unappetizing gruel.

Typhoon tomatoes have regular fruits, almost round or slightly flattened

This is a plant with a very powerful stem, standard. Branching and leafiness are average. When forming in several stems, it is imperative to tie up the side shoots - they are rather fragile. The height of the stem, as a rule, is limited at the level of 1.8–2.2 m. The first fruit cluster is formed low, above the 6–7th leaf. The total yield is 16-18 kg / m² or 4-6 kg per bush.

Chio-chio-san

It shows itself equally well when planting both in the open field and in the greenhouse. The State Register of Breeding Achievements of the Russian Federation (the variety has been listed in it since 1999) does not give any recommendations regarding the region of cultivation. In terms of ripening, it belongs to the medium early: the crop ripens in 110-120 days from the moment of emergence. You can count on about 4-6 kg per bush.

Fruits are ovoid or plum-shaped, smooth, without ribbing. The pulp is firm, but juicy. The skin is pink-red. The average weight of a tomato is 35-40 g. The structure of the brush is unique - it is very long and branched, up to 50 one-dimensional fruits are formed on each branch. The taste is excellent both fresh and canned.

Chio-Chio-San tomatoes during fruiting are easily recognizable by the characteristic type of brush

It is advised to limit the height of the bush at the level of 2 m. The plants do not differ in particular intensity of branching and dense foliage, nevertheless, one must not forget about the support. The tomato does not suffer from late blight, the creators have protected it from the tobacco mosaic virus.

Quite a lot of varieties and hybrids of tomatoes belong to the group of indeterminate ones. These are both old time-tested varieties and new selection. Each of them has undeniable advantages and some disadvantages. Their main feature is the unlimited growth of the stem, which necessitates the garter of the plant and its correct formation throughout the season. With proper care, these varieties are distinguished by high yields, the time spent on them fully pays off.

What are indeterminate tomato varieties and what is the difference and difference from determinant tomato?

At the beginning of winter, novice gardeners have the question of which type of tomato to give preference to when growing, which varieties should be cultivated in a greenhouse, and which ones in an open garden. To get acquainted with the types and varieties of tomatoes, you need to know what an indeterminate type of tomato is, since it is often used for growing in small areas.

Tall tomatoes have a number of advantages:

  1. Care. Indeterminate tomatoes are easy to care for. Usually it is enough to form a bush in time and periodically get rid of stepchildren.
  2. Disease resistance. To date, breeders have developed varieties that have good immunity to a variety of diseases and viruses.
  3. Bountiful harvest. High growth encourages the formation of more brushes. Under favorable conditions from 1 sq. m you can collect up to 16 kg of fruit.
  4. Long-term fruiting. Unlike low-growing varieties, indeterminate tomatoes bear fruit from July to October.
  5. Versatility. Tall varieties of tomatoes are suitable for both outdoor and greenhouse cultivation.

Along with the described advantages, indeterminate tomato varieties also have disadvantages:

  • tall plants are susceptible to overload, so the pinching procedure should be carried out regularly
  • a long period of fruit ripening requires sufficient daylight hours or additional lighting equipment
  • to prevent fruit rotting, it is imperative to provide support.


Growing features

These characteristics are so important that they largely determine the fate of your future harvest.

Location in a greenhouse or garden bed

It is advisable to grow indeterminate varieties of tomatoes in a high greenhouse (up to 2 m). With a long fruiting period, they produce crops for most of the year.

Important! Regular airing of the greenhouse will create optimal conditions for pollination and protect tomatoes from barren flowers.

Determinant and low-growing standard varieties of indeterminate tomatoes are more suitable for growing in the open field.

Seedling care

An error in the timing of planting and placement of seedlings on the site, ignorance of the rules for caring for them can minimize the result of your efforts.

Sowing dates

Planting tomatoes in the ground or greenhouse is preceded by the cultivation of seedlings. Seeds of indeterminate varieties are sown in early March. After 65-75 days, the seedlings are ready to move to the garden bed.

Determinant varieties are sown at the end of March. The seedlings ripen for 55-60 days.

Important! The optimum soil temperature for planting tomatoes is not lower than 15 ° C.

Stepping

In caring for tomatoes, it is important to promptly remove non-fruiting branches (stepchildren) from the bush, located between the base of the leaf and the main stem. This agronomic technique (pinching) is aimed at eliminating the irrational distribution of nutrients by the plant. The correct formation of the bush increases the yield.

Indeterminate varieties need pinching to a much greater extent than their undersized counterparts. Extra shoots are removed every decade throughout the growing season. The stepchildren gently break off, leaving a stump 1-2 cm high. Further, the bush is formed in one of the ways: only the central stem with fruit clusters is left, or the most developed stepson is chosen as the main one.

Important! Having chosen the stepson as the main shoot, after the formation of fruit ovaries on it, pinch the former main stem (pruning is not recommended). This will stop its further growth.

Determinant tomatoes are not prone to uncontrolled growth of green mass. For them, pinning is greatly simplified. Since the first three inflorescences bring the main crop, the process is aimed at accelerating their ripening. It is enough to remove all stepchildren below the branch on which the ovaries have formed. The bottom two stepsons should be left, otherwise the plant will stop developing and stop fruiting. This type of bush formation is called "three-stem" and is recommended for determinate varieties.

Important! The efficiency of the process will increase if you do not allow the growth of the stepsons to be removed more than 7 cm.


What is the difference between seeds

When choosing seeds, pay attention to the manufacturer's instructions - pure variety or hybrid.

Hybrids should be preferred. They have high productivity and early maturity, disease resistance.

They adapt better to changes in climatic conditions. The most important thing is to decide on the timing of sowing.

Seeds are planted at different times in different regions. For the middle lane, sowing dates:

  • indeterminate tomatoes - early March
  • semi-determinant - mid-March
  • determinant - end of March.
