Cucumbers Kurazh – variety description, photos, reviews

How the variety appeared

When Russian breeders were tasked with developing a new variety of cucumbers that would meet the wishes of gardeners in our climate, agro specialists got down to business. Breeders have developed a variety that is distinguished by a bouquet type of ovary placement, resistant to many diseases, and does not require pollination by insects - parthenocarpic. The variety was named Courage and registered in 2002.

The variety went “to the people”, was tested in the beds of Moscow gardeners and received recognition. Many bunches, in which 10-12 fruits were located at once, ensured a good harvest, and they required space and care, as for an ordinary cucumber - this made the variety popular.

To better understand what the “Courage f1” variety is, you can view the following photographs.

Description and characteristics of the variety

Cucumbers of this variety are pimply, have medium tubercles, usually even, dark green in color. Mature fruits reach a length of 10-14 cm and a weight of 100-120 g.

Productivity directly depends on the care of the bush and growing conditions:

in industrial greenhouse conditions, the yield can reach 50 kg per 1 sq.m.;
on private farms, a cucumber yields 20 kg per square meter, which is quite a lot.

The flowers are located in the axils, form a bouquet ovary, and a lot of fruits are set.

The variety is quite early ripening. The first fruit can be picked 35 days after planting, but the bulk ripens in 45 days.

Important! Cucumbers can be picked at the ripening stage that is convenient for consumption. There is no need to wait for maturity; this fruit is not used in its ripe form.

If Courage is grown in a greenhouse, fruiting begins earlier and lasts a long time. The productivity of one bush increases. The variety can also grow in an ordinary garden bed in open ground. The hybrid is characterized by the fact that it can give good results under the most unfavorable conditions.

Cucumber has a wonderful taste, it can be pickled, pickled, used in salads, or eaten fresh.

Greenhouse care

Cucumber Courage F1 requires stem formation. If the crop's side shoots and foliage are not removed, it will look like dense thickets. The hybrid requires support, so it is best cultivated on a trellis. The description of the variety will tell gardeners how best to care for the crop so that it can grow normally and produce a high yield.

Spraying and watering

In dry weather, the plant must be irrigated with water daily in the evening, spending up to 5 liters of liquid per bush.

The crop especially needs abundant watering at the stage of ovary formation and fruit ripening. During this period, cucumbers should be sprayed daily with water, preferably not chlorinated, but rainwater.

Top dressing

After planting the plant in a closed soil layer, it needs to be fed in the form of mineral components and organic compounds. After 14 days, the cucumbers will need to be fed with a nitrogen supplement in the form of 30 g of urea mixed in 10 liters of liquid. At the beginning of the flowering period, the crop needs to be infused with an infusion of meadow herbs and wood ash. When the ovaries form, the plant needs to be given nitrogen fertilizer based on phosphorus and potassium. In 10 liters of liquid, 35 g of superphosphate and potassium sulfate should be diluted.

Tying up

30 days after the bushes have grown noticeably, they need to be tied up. To do this, use fabric strips or twine. Cucumber Courage F1, like all bunched varieties, is formed into 1 stem.

Each stem should be tied to a trellis at a height of approximately 15 cm from the surface of the ground. The stem itself will need to be carefully wrapped around the rope.

Topping

The first 6 internodes must be removed along with the inflorescences or blinded. Additionally, 3 internodes need to be pinched at a distance of 2-3 leaves from the first node with ovaries. Afterwards, 2 bunches should be left on each shoot up to the trellis. When the bush reaches the length of the trellis, the main cucumber stem must be pinched or thrown over it. Then you will need to pinch at a distance of about 50 cm from the wire.

Next, you should leave 2 shoots that need to be wrapped around the trellis, removing all the side shoots.

Optimal conditions

Cucumber must be cultivated in a well-lit area. However, it should be taken into account that the cucumber does not prefer places that overheat under the rays of the sun, because the plant really likes moisture. During the hottest period, a little shade is recommended for the crop. Seedlings normally tolerate temperatures from +15 ℃ to +25 ℃.

It is recommended to remove side shoots with excess foliage so that the fruits can receive much more light if the bushes climb up. Therefore, cucumbers need to be provided with optimal lighting, otherwise overgrown specimens growing in the shade of tall plants will produce tasteless and small fruits. Cucumber Courage F1 is cultivated in greenhouses with artificial lighting in winter. Daylight hours should be at least 12 hours. Under these conditions, fruits begin to ripen 50 days after germination.

Advantages and disadvantages

Judging by the characteristics and description of the cucumber variety, F1 Courage has a number of advantages over other varieties.

Advantages

high taste qualities;
lack of bitterness;
resistance to common diseases;
The photographs show that there are a lot of cucumbers in the ovary, the variety has excellent yield, the bushes yield the harvest together;
perfectly adapt to any conditions;
low maintenance requirements;
the hybrid is recommended for industrial production;
good keeping quality, long shelf life;
early ripening;
does not depend on the presence of insects, since it pollinates independently;
good for vertical cultivation - saves space and increases productivity.

Flaws

since the variety produces large yields, it needs good care;
bush formation is required;
photophilous, in poor lighting the root system dies;
This is a hybrid, which means there is no way to collect seeds from your own crop;
In the absence of care, the yield drops sharply.

Disadvantages are typical not only for the Courage variety, but for any plants.

The variety is suitable for cultivation in open and closed ground. In greenhouses the fruiting period is longer; in open ground the bushes are stronger and more resilient.

Harvest and storage

Cucumbers require frequent harvesting - once every 2-3 days. It is necessary to free the bushes to form new fruits so that over time they do not lose their taste. When frost sets in, the entire crop should be removed from the bush.

There are several ways to store cucumbers:

in open boxes in a cool, dark place;
in the refrigerator in an open form;
in cool water (it is important to keep it clean);
the fruits can be coated with egg white and stored at room temperature.

Planting cucumbers

For greater fruiting, cucumbers should be grown in seedlings. Let's consider the technique of growing seedlings.

To avoid confusion, beginners are offered the following planting plan:

the seeds are treated with a growth stimulator (zircon, epin), then disinfected - dipped in a solution of potassium permanganate for 1-2 hours;
seeds are planted to a depth of 1.5-2 cm in heated soil in boxes;
the boxes are placed in a sunny window;
until germination, the box with plantings should be kept at a temperature of 25 degrees;
when the first leaves appear, the temperature is reduced to 18 degrees - it is under such conditions that the sprouts do not stretch, become strong, and acquire a rich green color;

You need to water the seedlings as the soil dries out; drying out and flooding the soil is detrimental to plantings;
when the seedlings produce 2-3 leaves (in about a month), they can be transplanted into a greenhouse.

Important! Courage is very light-loving. Choose the sunniest place for planting. If there is little light, the number of cucumber ovaries in the bunch is reduced.

Planting scheme: per 1 sq.m. – 2 plants.

It should be planted on cloudy days or in the evening, when there is no scorching sun rays. Roots that have not taken root will not yet be able to provide the plant with moisture; the bushes will die immediately.

Important! To correctly calculate the timing of planting seeds, remember when the soil in greenhouses or open ground warms up to 15 degrees, count a month from this time - during this time you can plant the seeds.

Preparing the planting site in the greenhouse

Cucumber Courage F1 (the description will tell novice growers of the crop how to properly prepare a planting site in a greenhouse) is well cultivated in light soil cover, which contains a high volume of humus. Fertile black soil, sandy loam or loamy soil layer is suitable for the plant. Before planting cucumber seedlings, it is necessary to prepare the soil cover in advance.

To do this, follow these steps:

In the autumn, organic compounds will need to be sent into the ground. It is necessary to mix 70 g of nitroammophoska with 3 glasses of ash and 3 buckets of manure. The composition is designed for 1 m2.
With the arrival of the spring season, the soil layer needs to be dug up using the bayonet of a shovel.
Then the soil should be fed with compost. For 1 m2 you will need 1 bucket of organic composition.

The cucumber will be cultivated normally in the area where carrots, cabbage, onions, potatoes and legumes were previously grown. Melon crops with pumpkin, melon and watermelon are considered bad predecessors.

Cucumber care

The cucumber hybrid Courage is not capricious, but requires regular care. Some rules must be followed.

Watering – water the cucumbers when the top layer of soil dries. Do not overfill - fungal diseases may appear. Lack of moisture causes the plant to wither, drop its fruits, and die.
Loosening, weeding - loosening is necessary so that an earthen crust does not form, blocking the access of air to the roots. Loosening is carried out after watering, when the water is absorbed. Then it is convenient to carry out weeding - the roots of the weeds are easily pulled out and do not remain in the ground.
Feeding – cucumbers should be fed with organic matter until the ovaries form. If you feed while the fruit is setting, the cucumbers will acquire an unpleasant taste.
Forming a bush - the procedure is necessary so that the plant does not waste energy on growing unnecessary green mass. Extra shoots and leaves delay the ripening period, thickening appears, fraught with fungal diseases, and the yield sharply decreases.

Attention! Harvesting bunched Courage cucumbers must be timely. If you delay harvesting even for 1 day, new ovaries will not form, the yield will drop, and the fruits will reduce their taste.

To rejuvenate the cucumber and increase productivity, experienced gardeners use its characteristic feature - the formation of roots at the nodes of the shoots when in moist soil. The shoots are buried with loose, fertile soil mixed with humus. The soil is kept moist, stimulating root formation. An additional root system increases the level of mineral nutrition of the cucumber plant from the soil. Old roots with a reduced ability to absorb minerals are compensated by young ones.

Gardeners' advice! The filling of cucumbers is accelerated if you place a container with fermenting grass in the greenhouse. This will increase the humidity and give the cucumber the carbon dioxide it needs.

Method for increasing yield

Courage is a vigorous, light-sensitive hybrid that tends to shade itself. In conditions of high humidity, sufficient heat, but lack of light, it forms leaves that are too large - “lazy”. A lazy leaf shades the plant even more - the working leaves of the middle and lower tier reduce productivity.
Experienced summer residents recommend periodically removing some of the lazy leaves (1 - 3 leaves at a time) leaving the petiole, improving the illumination of the bush. This technique allows you to increase the efficiency of solar radiation by working leaves, increasing the productivity of the cucumber. The fruits grow and ripen faster, the yield and harvest time increase.

Diseases and pests

The undoubted advantage of the Courage F1 hybrid is increased resistance to diseases most typical of cucumbers. This achievement of breeders practically does not suffer from true and downy mildew, mosaic disease (green cucumber mosaic), olive spot, as well as from all types of root rot. But the list of fungi, viruses and bacteria that infect cucumbers is not limited to these diseases.

Table: diseases that may affect Kurazh cucumbers

Disease	Symptoms	Preventive measures and treatment
Cladosporiosis	Dark gray or brown spots of an almost regular round shape appear on the leaves of cucumbers. Over time, the affected areas of the leaf dry out and die, and holes form. As the fruits ripen, the fungus spreads to them. Eating cucumbers is almost impossible because of the unpleasant taste.	For prevention - daily ventilation if cucumbers are grown in a greenhouse. To cure plants, they and the soil need to be sprayed with a 1% solution of Bordeaux mixture (100 ml per 10 l). Treatment is carried out at intervals of 8–12 days. The norm per plant is 0.3–0.5 l.
Sclerotinia (white rot)	It affects lashes, leaves and cucumbers. First, barely noticeable white spots appear on them, resembling a thin coating, then the tissues become soft, translucent, and watery. If the problem is not dealt with, the plant will rot completely.	Carefully follow the recommendations for watering, do not turn the greenhouse or garden bed into a swamp. If the disease has not gone too far, the affected branches, leaves and fruits are simply cut off, and the sections are disinfected with a 2% solution of copper sulfate. When the bush has rotted almost entirely, the only way out is to tear out and immediately dispose of the plant. The soil in this place is sprinkled with crushed coal or slaked lime (200 g/m²).
Ascochyta blight	Yellowish-brown or beige-brown spots appear on the fruits and leaves. Then these areas quickly turn black and die. Leaves and cucumbers become deformed.	At the first sign, spray the affected plants with a 2% solution of Bordeaux mixture or any other fungicide (Topaz, Bayleton, Strobi).
Anthracnose	Beige or yellow areas of dead tissue appear on the leaves. The fruits have not too deep, but wide dents filled with pinkish mucus or covered with a coating of the same color. Over time, pink turns to black. You can't eat these cucumbers, they are too bitter.	The bushes are sprayed with a 1% solution of Bordeaux mixture or a 0.5% solution of copper oxychloride once a week, no earlier than 3-4 days before the next harvest. Spraying is repeated until the problem is resolved. If most of the bush is affected, the procedure will have no effect. Another option is a bleach suspension. Take 30–35 g of the substance per 10 liters of water, mix well and spray the cucumbers every 10–12 days. After such treatment, the harvest can be harvested no earlier than 3 weeks later.
Fusarium	The disease develops at lightning speed. An absolutely healthy-looking cucumber bush can wither within a day or even half a day.	There is no effective treatment. For prevention, the soil can be spilled with boiling water or a bright pink solution of potassium permanganate before planting seeds or seedlings.
White cucumber mosaic	Small yellowish and whitish star-shaped spots appear on the leaves, with white ones clearly predominant. The fruits have thin longitudinal white and yellow stripes.	It is useless to fight the disease. You can try to transplant very young plants to another place, having previously disinfected the soil.
Bacteriosis	Small “ulcers” appear on the cotyledons, and brown spots of a characteristic shape with sharp corners appear on the leaves. They are slightly convex, as if there is some kind of liquid inside. If there is high humidity in the greenhouse, cloudy drops of a dark brown color are visible on the back of the leaf. Then the affected tissues die and holes form on the leaves. The disease spreads to whips and cucumbers.	Protect plantings from cold drafts. Leaves showing signs of disease are immediately plucked and destroyed. Bordeaux mixture (2–3% solution) will help to cope with the problem.

With bacteriosis, the leaves become covered with “ulcers” and gradually die off.

There are no effective control measures against white cucumber mosaic - focus on prevention

Fusarium can destroy a completely healthy cucumber bush in less than a day

Anthracnose is easily recognized by spots on the fruits of a pinkish tint and a coating of the same color on the underside of the leaves.

Ascochyta blight is a disease that leads to deformation and drying of shoots and fruits

If measures are not taken in time, the cucumber bushes will completely rot under the influence of the white rot fungus.

Cladosporiosis is a fungal disease that makes the crop completely inedible.

Cucumbers are loved not only by people, but also by pests. The Courage variety is no exception. And here the breeders are powerless. They are not yet able to protect their achievements from insects.

Table: pests from which Kurazh cucumbers need to be protected

Pest	Symptoms	Preventive measures and treatment
Black and green aphids	Insects settle in whole colonies under the leaves, sucking the juice from them. In addition, aphids are carriers of all kinds of viruses, fungi and infections.	There are insecticides specifically designed to combat aphids - Strela, Inta-Vir. The solution is prepared according to the instructions and sprayed on the plants. The most popular folk remedy is hot pepper infusion. 3-4 pods are cut, add 200 g of dry tobacco crumbs (preferably grown yourself) and pour in 10 liters of hot water. Tobacco can be replaced with the same amount of sifted wood ash. The container is closed. After a day, filter the liquid, dissolve 25–30 g of finely shaved laundry soap in it and spray the plants. Aphids do not like strong odors. Therefore, in addition to pepper, you can use onion, garlic, and tomato tops to prepare the infusion. Next to the cucumbers in the greenhouse, plant dill, thyme, mint, rosemary, wormwood, marigolds and other strong-smelling plants.
Greenhouse whitefly	This small insect with whitish wings infects leaves and vines, which soon turn black and die, as the pest produces a sticky mass that interferes with the process of photosynthesis.	The drug Actofit works well against whiteflies. Cucumbers are sprayed at intervals of 8–10 days. Do not forget about such control measures as manual collection of pests and special adhesive tape.
Spider mite	Pests settle on the lower part of the leaf and feed on its juices, while simultaneously covering the leaf with a dense white web. The leaves affected by the mite first turn light green, then pale yellow and die.	Acaricides specifically designed to combat ticks are Acartan, Zolon, Metaphos, Phosfamide, Tsidial, Tedion, Talstar, Beacon. A significant disadvantage of the drugs is that the pest very quickly develops immunity to them. Therefore, during repeated processing, the products must be alternated. For prevention, loosen the soil more often to destroy future generations of mites. Folk remedies - infusion of yarrow, dandelion leaves and celandine. Chop the greens, fill the container about a third, fill it with cold water and leave for 3-4 days. The resulting infusion is filtered and sprayed on the cucumbers. After the final harvest, greenhouses and greenhouses are disinfected by closing all doors and windows and burning a piece of sulfur.
Root nematode	It settles in the roots and feeds on plant juices. If you dig up a bush, you can see small tubercles, growths, nodules and irregularly shaped swellings. The pest laid larvae in these places. The cucumber practically does not grow, the yield is reduced by at least half.	There is no effective remedy. Affected bushes are immediately removed from the greenhouse or garden bed and burned. A layer of soil at least 50 cm thick must be removed and replaced. For prevention, before planting, the soil is spilled with boiling water or treated with steam, all tools are thoroughly disinfected and only healthy seedlings are planted.
Sprout fly	Its larvae hatch in the spring and feed on seeds and young shoots. They don't disdain cucumbers either.	Strong seedlings or at least germinated seeds are planted in the ground. 3–5 days before planting, the soil is dug up or well loosened and watered with a solution of Fufanon, Kemifos, Novaktion, Iskra, Malathion. They also spray seedlings 5–7 days after planting in the ground.
Slug	Cucumbers affected by a massive invasion of slugs practically do not bear fruit, and the crop that is still harvested is poorly stored and rots, noticeably losing its presentability. Pests also carry spores, viruses and bacteria that cause other diseases. Sticky silver marks are visible on the leaves.	An option for the patient and attentive is manual collection. Be sure to use tweezers. Do not throw away the collected pests, but destroy them. You can set traps - several deep containers are dug into the ground, beer, sugar syrup or jam are used as bait. Once every 2-3 days, the bait needs to be changed and all pests that come across should be destroyed. There are also special drugs - Meta, Ferramol, Thunderstorm, Slug Eater, but they are harmful not only to slugs, but to people and pets. Surround the bushes with a low fence made of coarse sand, ground eggshells, ash, pine needles, and brick chips.
Thrips	Small insects attack leaves and vines, sucking out the juice. Rapidly growing spots of beige and yellow color with angular outlines appear on cucumber bushes. Then the spots turn brown and the bush dries out.	For prevention, you need to deeply dig up the bed or soil in the greenhouse every fall. Then the soil is sprayed with a 0.5% solution of Karbofos or Actellik. The plants themselves can be sprayed with the same product at intervals of 10–15 days. An infusion of hot pepper is suitable as a folk remedy.
Wireworm (larva of click beetle)	The wireworm penetrates the roots, and from there into the stem and feeds on the juices of the plant. The bush suddenly stops bearing fruit, dries out and dies.	A good preventative measure is digging up the beds, regular weeding and destroying all plant debris (cucumber tops, weeds) in the fall. In severe cases, use the chemicals Bazudin, Calypso, Diazinon.

Photo gallery: What pests should Kurazh cucumbers be protected from?

It is generally accepted that wireworm larvae prefer potatoes. But they won’t disdain cucumbers either

Thrips are small insects, but they are able to destroy an entire cucumber bush, even more than one

Slugs are carriers of pathogenic fungi, bacteria and viruses that can significantly harm cucumbers

Sprout fly larvae feed on any sprouted seeds and young seedlings, including cucumbers

Atypical deformations on the roots - places where the root-knot nematode laid larvae

Spider mites feed on cucumber juice, simultaneously weaving leaves and ovaries with thin threads resembling a cobweb

The sticky substance secreted by whiteflies interferes with the normal supply of oxygen to plant tissues

A massive invasion of aphids will leave cucumber bushes without greenery, and you without a harvest
