The Tumi cucumber variety is characterized by high yield. On average, up to 20 kg of excellent quality fruits are harvested from 1 m2. They are easy to grow, even a beginner can do them.

Characteristics of the cucumber variety Tumi

Care is traditional and consists of watering, weeding, maintaining temperature conditions, and fertilizing. Correct growing technology is the key to an excellent harvest.

Characteristics and description of the variety

The Tumi F1 variety was bred by Dutch breeders of the company Enza Zaden Beheer BV. It was included in the state register of the Russian Federation in 2015. Its main feature is resistance to different climatic conditions, so the variety can be grown in any region, including both southern and northern.

Did you know? Maximum fruiting occurs in the first wave of ripening

-
40 days after emergence.
Further, the Tumi F1 variety continues to bear fruit, but in smaller quantities. Characteristics of the variety:

basic: mid-early, salad, self-pollinating (parthenocarpic) cucumber hybrid of the first generation with good fruiting;
ripening: 38–42 days after sprouts appear;
yield potential: high, about 13 kg/m²;
Disease resistance: high to cladosporiosis and powdery mildew.

Can be grown in open areas and in greenhouses. Cucumbers have good taste and keeping quality. They are used in salads, as well as in preparations for the winter.

Features of the bush and fruits

The bushes are formed by vines of medium length. At the same time, the main vine produces the main harvest, and the creation of additional lateral shoots can increase the yield by 20–30%. The plant produces female flowers. They often grow in bunches, 2 per node.

Characteristics of the cucumber plant:

bush: medium branched, with strong vines, indeterminate;
leaves: dark green, small;
fruit: short, cylindrical, finely tuberculate;
color: green, with a lighter spot and stripes at the ends;
peel: slightly rough, with white spines;
fetal weight: 120–150 g;
size: 15 cm;
pulp: without bitterness, aromatic.

Zelentsy are resistant to yellowing and deformation. The variety is tolerant of cool weather and temperature changes.

Fruitfulness

Due to the branching of the bush, Tumi is extremely productive. The originator declared the yield to be 13 kg/m², while gardeners achieve results of 20 kg/m². On average, one bush per season can bear up to 6 kg of fruit. The variety is characterized by uniform ripening of vegetables.

Ripening and flowering dates

Cucumbers originate from the tropics, although they have adapted to more moderate temperatures. But this does not prevent them from ripening quite early. Tumi is a mid-season variety. Its fruits fully ripen in 38–40 days after the first shoots appear, but they can be eaten earlier.

Important! When the air temperature drops below +15° C, plants

“
freeze
”
in growth.
The distinctive feature of Toomey is that he does not shed the ovary in such a situation. Sowing seeds in the ground should be carried out:

in the northern regions - at the end of May or beginning of June;
in central Russia - in the first ten days of May;
in the south - in the last ten days of April.

Shoots will appear on about 5 days, but the plants will begin to bloom in 20–25 days. To speed up fruiting, in regions where there is a large gap between day and night temperatures, plants must be covered with a film or agrofibre cover at night.

Did you know? Cucumbers began to be cultivated in India and Mesopotamia 6,000 years ago. According to Indian legend, a cucumber contains exactly 60,000 seeds, which is exactly how many children the Raja is credited with having

“discovery”
of cucumber as a vegetable crop.

Strange things started from landing

I have a special love for cucumbers. They sprout for me only in sawdust. No matter how hard I tried to grow them in the ground, they either didn’t sprout or were somehow sick.

This is where things got weird. I sowed them in regular soil in plastic cups. Because even 1 bush would be enough for me for the experiment. I sow new varieties and hybrids in limited quantities.

But all 5 seeds sprouted and the seedlings developed very powerfully. She was stocky and grew faster than other cucumbers with the same care.

Sowing preparation and technology

Cucumbers can be planted either by direct sowing of seeds in the ground or by seedlings. Cultivation in greenhouses and open ground is allowed. Seeds are sown both dry and germinated. The choice of methods depends on the personal preferences of the farmer.

Cucumbers are quite light-loving, so regardless of the choice of sowing method, for cultivation you will need a well-lit area, drained fertile soil and regular watering.

Optimal conditions for the growth of the Tumi variety:

air temperature - +21°...+23°;
humidity - 60%;
illumination - an area with bright sun;
watering - once every 5 days;
loosening - a day after watering;
fertilizing is mandatory during the growth, flowering and fruiting phases.

Cucumber is heat-loving. Therefore, depending on the climatic characteristics of the region, the timing of planting seeds will differ. In temperate climate zones, cucumbers are planted in ridges in May - from the beginning to the middle of the month.

You will be interested to know how to properly grow cucumbers on the windowsill and balcony.

In areas with colder climates - from the end of May until the 10th of June. It is not worth planting cucumber seeds at a later date - the crop does not tolerate heat well. And this can affect the formation of fruits.

In the open ground

Start sowing by preparing seeds, soil and containers for seedlings if you want to speed up the time of obtaining the first greenery.

Seed preparation includes:

Grain calibration. This is soaking the seeds in a warm solution of table salt. The floating seeds are thrown away as they will not sprout. The rest are washed from salt.
Disinfection in a pale pink solution of potassium permanganate for 30 minutes. In this case, the death of pathogenic bacteria occurs.
Treatment with “Fitosporin” to strengthen plant immunity. The drug is used according to the instructions.
Germination within 3–4 days. Place wet gauze in the tray, place the seeds on it and cover them with another layer of gauze. Moisture should not dry out.

If stable warm weather with night temperatures not lower than +15° C has established, the seeds are sown in the ground. If the soil in which the sowing will be carried out is poor in composition, then after digging up the area and removing the weeds, fertilizers are applied. These can be substances of both organic and inorganic origin. The application rate for manure is 5 kg/m².

If possible, ridges are formed from north to south. This provides better lighting to each plant. An excellent option for borage are “warm” ridges 25 cm high. They consist of several layers. One of them is rotted manure with the addition of ash. It creates a kind of thermal cushion. Plants on such a cushion grow faster and bear fruit more actively.

Hybrid characteristics

Tumi cucumber F1 is a hybrid that, thanks to grafted parthenocarpy, actively bears fruit in protected and open beds. The culture forms greens no later than 1.5 months after the sprouts appear.

The plant is characterized by continuous growth in length and active formation of shoots on the main stem. The distance between nodes is short. Cucumber has low foliage. Two female flowers develop in one leaf axil.

The fruits are compact - up to 12 cm. Their external characteristics are clearly visible in the photo. As you can see, the cucumber is not without tubercles and thorns. The degree of tuberculation is average. The skin is uniformly green in color. The taste of greens is highly rated. It is not bitter, juicy, and the seeds cannot be felt when chewed.

Features of care

Care consists of:

regular watering;
weed removal;
applying fertilizers;
mulching;
stepsoning.

Water the cucumbers at the root with water at “summer” temperature. On the second day after watering, borage is weeded, removing weeds. Weeding must be done carefully so as not to damage the surface root system.

Some gardeners use mulching between rows to prevent the soil from drying out quickly and stop the growth of weeds. Dry leaves, wood chips or other materials are used as mulch, laid in an even layer 3–5 cm thick.

Watering and fertilizing

Proper care of cucumbers is compliance with the irrigation regime and the correct microclimate. The water should be warm (+20°…+25° C). It will be useful to water the cucumbers with rainwater. During periods of too hot weather, when the soil is overheated, it is recommended to water with cool water. The best type of irrigation is drip.

At the same time, the water slowly moistens the soil, saturating it near the roots very well. Watering is carried out as the soil dries out, approximately once every 5 days. Water consumption is 8–9 liters per 1 m² for the entire period of bush growth. When the cucumbers begin to bloom, watering is done once every 7 days. In the development phase of green plants, it is again made more frequent - once every 3 days. Water consumption increases to 25 liters per 1 m².

Important! With irregular watering, cucumbers begin to taste bitter. And with a lack of moisture, they become small and deformed.

This is due to the fact that a cucumber consists of more than 86% water and for good fruiting it definitely needs a lot of liquid. In hot weather, without rain, containers with water are placed between the rows of bushes to increase air humidity. During the rainy season, watering is reduced and watered as the soil dries. By the end of summer, less water is irrigated, not only because the main crop has been harvested. Nights become cooler and less moisture evaporates.

The nutritional value of the soil is important for cucumbers. In household plots, as well as in fields, soils are depleted by long-term cultivation of various crops. To restore soil fertility, fertilizers are applied. There are fertilizers of organic and inorganic origin. Each type has its own advantages. So, organics are products of animal and plant origin: manure, meat and bone meal, peat, straw, green manure, algae, ash.

They decompose gradually, which is good for ensuring stable plant growth. Inorganic fertilizers are obtained from minerals through chemical reactions or the influence of natural processes - weathering, exposure to water or volcanic activity. Fertilizers in this group are presented in granules, powders or aqueous solutions. They are quickly absorbed.

Also read about how to properly feed cucumbers with urea, iodine and yeast.

Therefore, they are used if you need to quickly increase the nutritional value of the soil. When planting, it is preferable to use rotted manure. It is a source of nitrogen, a microelement necessary for the growing season of a cucumber plant. Ash is added to it. It is a source of potassium, necessary for intercellular metabolism in plant tissues.

The rate of manure application is 5 kg/m².

If you prefer inorganic fertilizers, the composition may look something like this:

nitrogen - 30 g per m²;
potassium - 45 g per m²;
phosphorus - 12 g per m².

It is advisable to fertilize cucumbers three times during the growing season. The first feeding is carried out 14 days after planting in open ground, the second - at the moment of ovary formation, the third - during the period of active fruiting. If cucumbers are harvested until autumn, then some farmers also use a fourth feeding .

Garter and bush formation

Cucumbers are vines that grow in the warm season in our climate. For convenience, they need to be provided with support. The stems in each internode have special tendrils for attachment to supports. With their help, the plant climbs to any height.

Important! It is forbidden to prune before the stems reach a height of half a meter. If an underdeveloped plant is pruned, it may refuse to bear fruit and lose color.

The purpose of tying is to lighten the weight of the fruit that the cucumber vine must hold. The structure for fixation can be a pole, a horizontal or vertical trellis, a trellis, a small fence or a fence. A garter is needed after the shoots reach a length of 0.5 m and is carried out as the plant grows. 3-5 weeks after the cucumbers are planted in the ground and begin to grow, it is time for pruning.

Scheme for tying cucumbers. The length of the stems will be at least 0.5–0.6 m. Side shoots, unnecessary leaves, and damaged parts of plants must be removed. The cucumber is formed into one stem, which wraps around a support. Side shoots are removed by pinching them above the first leaf and the first ovary at the bottom of the plant. 2 leaves and 2 ovaries are left in the middle, and 3 leaves and 3 ovaries are left in the upper part. The side shoot is cut at an angle of 45 degrees.

Soil care

The soil under cucumbers must be loosened and weeded to remove weeds at intervals of 5–10 days. The treatment is carried out with a garden hoe, deepening it no more than 5 cm, so as not to damage the roots of cucumber plants. Weeding is carried out as weeds appear, and loosening is carried out after rain or watering.

Read more about what to do if cucumbers do not grow well.

If there is mulch on the ground, then weeds do not grow, the soil does not become compacted and does not require loosening. This is practical, especially if the gardener does not have enough time for additional actions on his site. During the summer, the mulch will have to be renewed periodically, as the lower layer will decompose, enriching the soil with humus.

Reviews

When describing cucumber varieties, gardeners pay attention to resistance to weather conditions and the taste of the fruit. Toomey scores well on these measures.

Larisa, Volkhov: “We have a cool and not very sunny climate. The weather has no effect on the appearance of fruits and a huge number of shoots, the old ones of which must be removed. You don’t need insects for pollination, it’s convenient.”

Igor, Mozhaisk: “The Tumi cucumber grows equally well in a greenhouse and in open ground. The fruits are large and beautiful, as in the photo on the package. Good taste - the flesh is juicy, dense and without a bitter aftertaste.”

Disease and pest control

Major plant diseases occur due to improper air exchange and moisture. Thickened plantings create excellent conditions for insect life and fungal growth. Moist air after rain will promote their development. Therefore, farmers begin planning borage by choosing varieties for planting and studying the disease resistance of one or another variety.

Tumi is resistant to cladisporium and powdery mildew. Farmers also note its resistance to other fungal diseases. The manifestation of diseases is accompanied by spots on leaves or fruits, rotting, and wilting. In such a situation, crops are treated with fungicides. Most often these are copper-based solutions - Bordeaux mixture 1% or copper sulfate. Copper ions form a protective layer that destroys pathogens.

We recommend that you learn how to get rid of plaque on cucumber leaves.

Main diseases:

Alternaria or dry spotting - a fungal disease that manifests itself as small brown spots (2 cm) on the leaves. Develops at high temperatures and humidity. For treatment, double spraying with Bordeaux mixture is recommended with an interval of 10 days.
Anthracnose - This is also a disease of a fungal nature, in which yellow and light brown spots appear on the leaves. The conditions for the development of the fungus and its treatment are similar to Alternaria.
White rot occurs more often in greenhouses. White mycelium of the fungus develops on the affected fruits. To prevent infection, the soil is treated with Trichodermin. This is a highly effective drug. Its action is based on the introduction of a beneficial fungus into the soil, which destroys rot pathogens and creates a favorable environment for the development of beneficial microflora. Infected plants are destroyed, and the rest are treated with Roval or Sumilex.
Cladosporiosis or olive spot often affects borage. Light brown spots with an olive border appear on the outside of the leaves. The Tumi variety is resistant to this disease.
Root rot appears due to improper watering. If moisture often stagnates at the roots, then the plants begin to wither and rot. To prevent the problem, control the water temperature and frequency of watering. Destroy diseased plants.
Downy mildew is a fungal disease that appears as yellow spots on cucumber leaves. For prevention and treatment, borage is sprayed with Strobi and Quadris.
Powdery mildew - the most common disease. Appears as a silvery coating on the leaves. Tumi is also resistant to this disease.
Rhizoctoniosis or black scab forms black spots on leaves and fruits, which leads to the death of plant tissue. To prevent the disease, it is necessary to disinfect the soil and treat it with preparations such as Trichodermina. Plant protection is carried out by spraying with copper sulfate or Ridomil Gold.

To protect cucumbers from diseases, be sure to remove plant debris from the site, disinfect the soil and observe crop rotation, and also plant disease-resistant varieties.
Did you know? If you place several pieces of cucumber in an aluminum container and place it on the garden bed, the smell resulting from the chemical reaction will repel pests. It is not felt by people, but insects catch it well.

The main pests of cucumbers are aphids, mites and other sucking insects. The result of their activity is damage to the leaves, a sticky coating left by aphids. The insects themselves can often be found on the underside of the leaf. In this case, the crops are treated with appropriate insecticides.

Main pests:

melon aphid - one of the most dangerous pests. It appears at the moment of flowering, destroying the flowers and then the leaves of the plants. Weed control reduces the likelihood of aphids in borage. For treatment, spray with a solution of insecticidal soap. Treatment rate: 2 l/m². The procedure is repeated after 7 days.
Action spider mite manifests itself as small light dots on the leaves and the presence of small cobwebs. The main preventive measure is to maintain constant humidity at least 60%. The tick does not tolerate moisture. For treatment, plants are treated with Fitoferm and Karbofos.

The most productive cucumbers

The desire of every amateur gardener is to see the result of his work, and for gardeners this result is productivity. When developing new varieties of cucumbers, breeders pay special attention to two indicators - the resistance of new varieties to characteristic diseases and the number of fruits during the growing season. However, among the whole variety of hybrids, there are those that occupy leading positions in quality and yield.

The best productive hybrids

When choosing seeds to obtain powerful seedlings, and then a high yield of hybrids, be sure to pay attention to the presence of the F1 symbol on the packaging. It means that these seeds are the best in terms of performance and are obtained by crossing two different varieties.

In addition, be sure to take into account that the hybrid must belong to the “early ripening” group and have a long growing season. Also pay attention to the ripening period of cucumbers - its choice depends on the purpose of using the fruit. For example, if you want to get early fruits for salads, then you need to focus on high-yielding varieties of the spring-summer period. If the purpose of cultivation is to preserve vegetables, choose hybrids with a ripening period of “summer-autumn”.

Seeds of productive cucumbers, highly appreciated by experienced gardeners:

Pickle F1

Shows good resistance to fungal and viral diseases, tolerates dim lighting in film greenhouses and greenhouses.

This early hybrid has proven itself to be the best when grown in film greenhouses and for open ground. The fruit ripening period is 1-1.5 months. Average size – 10-12cm. The fruits are dark green in color and have a thick skin.

Sparta F1

An insect-pollinated hybrid intended for cultivation in open ground conditions and in polycarbonate greenhouses with an opening top. Dense, juicy fruits reach sizes up to 15cm, perfect for salads, pickling and canning.

Zozulya F1

Long periods of growing season are maintained in greenhouses, and during the period of full ripening, up to 15-20 kg are removed from one bush.

Despite the fact that the variety is self-pollinating, the best early harvests can only be obtained when growing the plant in open ground conditions. Resistant to cucumber mosaic and olive blotch diseases.

Yield varieties of cucumbers

Seedlings of these varieties are intended for both open ground and greenhouses. The only thing that needs to be taken into account during the growing process is that almost every species presented is insect-pollinated.

Bush

The fruits are small (the weight of one fruit is from 80 to 100 g), but with proper care and feeding, up to 20 kg of cucumbers can be harvested from one bush during the growing season.

An early ripening variety with an average fruit ripening period of 1.5 months. The main feature is the bush method of cultivation. The variety is universal, therefore it is used for preparing salads and canning, and is grown in open ground conditions, greenhouses and greenhouses equipped with opening walls or a roof.

Voronezh

The variety is universal, suitable for canning, pickling and fresh consumption.

The variety belongs to the group of summer-autumn varieties, with a late ripening period. The seeds are grown in greenhouses, and then the seedlings are transferred to open ground conditions. The plant is insect-pollinated, but feels equally good both in beds and under a greenhouse film. During the ripening period, the cucumber reaches a size of 15cm and weighs 100-120g.

Pinocchio

A high-yielding variety that tolerates sudden temperature changes. The fruit ripening period is 1.5 months. The plant is insect-pollinated, so it is planted in open ground conditions. Early seedlings can be covered with film for some time. Buratino is one of the varieties that have proven themselves well during transportation and long-term storage. That is why it is preferable for those gardeners who sell vegetables. On average, the weight of a mature fruit reaches 100-120g, with a length of 10 to 15cm.

Fruiting varieties for growing in greenhouses

To obtain high yields in greenhouse conditions, it is necessary to choose seeds of early self-pollinating varieties. In addition, plants must be resistant to low temperatures and diseases, tolerate low light levels and long growing seasons.

Among all the diversity, the following can be distinguished:

Meringue F1

An early hybrid with a rapid ripening period. From transplanting seedlings into greenhouse soil to full maturation, it takes 35 to 40 days. A distinctive feature of Meringue is that cucumbers are large-lumpy, richly dark in color, and have medium sizes - the weight of one fruit is from 80 to 100g. The variety is resistant to cladosporiosis, powdery mildew, and root rot, characteristic of greenhouse plants.

Alekseich F1

The hybrid is not susceptible to infection by powdery and downy mildew, or fungal infections.

A universal early-ripening variety, specially bred for greenhouse and greenhouse cultivation. Fruit ripening period is 35-40 days. The fruits are small in size (8-10cm) and weigh up to 100g, so they are used mainly for canning.

Benefit F1

An early hybrid with high yield. Full ripening occurs within 40-45 days after transplanting the seedlings into greenhouse soil conditions. The average weight of the fruit is 100g, and the length does not exceed 12-14cm. The variety is resistant to fungal and viral diseases and retains commercial quality for a long time under long-term storage conditions.

Murashka F1

An unusual early hybrid, distinguished by its tufted ovaries. This creates comfortable conditions for gardeners with abundant harvests and long growing seasons.

The fruits have a coarse, dark green skin with small spines, and excellent taste. The hybrid is resistant to powdery mildew and powdery mildew diseases. The ripening period is 40 days, the fruit size is up to 100g.

Leaders of sells

A high-yielding variety that allows you to get 12-15 kg of cucumbers from one m2 during the period of fruit ripening. Tumi is characterized by high endurance, unpretentious to lighting and regular watering.

The skin of the fruit is dark green, dense and lumpy. An interesting feature of the variety is that when the ovaries are tied to a long stake, the crown of the bush can grow to an area of 2-2.5 m2. The ripening period is 45-50 days, the average length of the fruit is 10 cm.

Courage, Sigurd

The most productive varieties of cucumbers, which are the undoubted leaders in sales on Russian agricultural markets. Seedlings are planted at a distance of 1.5-2 m, since the varieties belong to the group of shrubs. Seeds are planted in late spring or summer, the growing season is 40-45 days. During the harvest period, up to 15 kg of cucumbers can be harvested from one bush. Both one and the second variety require a large amount of organic fertilizers, since the powerful and rapid growth of the plant quickly depletes even the most fertile soil.

Conclusion

In order to get a high-quality and large harvest, take into account the growing conditions, regularity of watering and fertilizing the plant with organic fertilizers. When choosing seeds, consider which variety or hybrid can best satisfy your wishes - the time of year and the amount of harvest, the purpose of its use. Pay close attention to the instructions for planting seeds and growing seedlings; most likely, the seedlings will require separately prepared soil with components such as soil or humus.

Harvest and storage

Cucumber fruits grow quickly. Harvesting must be done regularly, starting from the moment the first batch ripens. Cucumber plants are able to control the formation of ovaries, so unpicked cucumbers delay further formation of ovaries. Cucumbers are harvested in the morning, daily or every other day. The fruit is supported by hand and the tail is cut off with pruning shears, leaving about 1.5 cm.

Collected cucumbers are stored for 7–10 days without loss of quality in a cool, dry room. The air temperature in it should not exceed +10°C (in the basement, cellar). The box for cucumbers should have holes for ventilation of vegetables. Greens can be stored in a plastic bag in the refrigerator for about 14 days.

Learn how to preserve crispy cucumbers.

The bag will not allow the cucumbers to lose their elasticity and wither. Caring for cucumbers is not too difficult. If the site for cultivation is chosen correctly and basic agrotechnical measures are followed, then you can reap a good harvest of tasty vegetables.

Instant Harvest

I used to not believe in the fact that you can sow cucumbers in mid-May, and after 4 weeks you can see the first greens on the plant. And that’s how it all happened. Sowing May 11, 2022. The first harvest of 9 cucumbers at once is June 18, 2022.

Gradually the number of growing gherkins increased. And by the end of June we were collecting a 10-liter bucket of gherkins every other day from these 5 bushes.

All the fruits were as chosen - 8-10 cm in length.

Smooth, without emptiness inside, sweetish in taste. I haven't come across anything with bitterness throughout the entire season.

The number of cucumbers began to decrease around mid-August. This hybrid has a peculiarity - gherkins are formed mainly on the central stem in bunches of 3-4 pieces.
