Growing cucumber seedlings at home

When to plant this crop outdoors? To answer this question, gardeners take into account the peculiarities of the weather and the sowing calendar. In the first case, you can understand at what time you can safely plant in the soil, and with the help of the second, the most suitable date for such an event is selected.

When can you plant cucumbers at home

This is best done at a time when the soil warms up to fourteen to fifteen degrees Celsius. Here it must be borne in mind that if the temperature is kept at a minimum value, the vegetable will hardly begin to grow. Simply put, the beds should be warmed up even better. Otherwise, the plant will be exposed to growth only in the daytime, under the sun's rays. And on cool nights, the process will pause.

It is quite natural that the decision to land is perceived by many with great caution. More experienced gardeners prefer to trust their own experience. So when fifteen degrees of heat in the ground is established, you can safely start planting, because in the spring the thermal regime will only increase, which will provide favorable conditions for growth.

In the middle regions of our country, the soil composition in the greenhouse warms up by mid-May. At this time, you can land without much risk, and there is always the opportunity to arrange additional heating. For this purpose, manure, overheating hay or sawdust, is laid on a half-meter depth of the beds. A simpler option is to cover the beds with plastic wrap.

You can speed up the harvesting somewhat without waiting for the May period.

For this, seedlings are pre-grown. For planting seeds for seedlings, the time is determined simply - a three-week period is counted from mid-May. This time will be quite enough to get perfectly formed sprouts. This method of determining the planting is good if you plan to use a greenhouse for further growth. Seedlings intended for open ground are recommended to be sown in early May.

What days is correct landing possible

Sowing time can be divided into three periods:

    • early. For planting in open ground, you must wait for the fifth of June. But if the soil is warm enough and the climate in your area is warm, then sowing can be done between the fifteenth and twenty-fifth of May.
    • middle. This sowing is carried out in June, until about the tenth. Any cucumber varieties are suitable for him. The first crops can be harvested with the onset of August
    • late. For this period, it is recommended to sow varieties intended for salting. The advantage of this sowing is that fresh cucumbers will delight you before the onset of frost.

Cucumbers planted at a lower temperature will either stop growing or die completely.

This year's lunar calendar has determined the following landing days:

monthauspicious daysconditionally favorable days
March1, 6 – 7, 29 – 314 – 5
April9 – 10, 27 – 281 – 2
May26 – 272 – 3
June8 – 93 – 4

Preparing cucumber seeds for sowing

This procedure is required at home. In order for the seeds to swell, they should be placed in water at room temperature for ten to twelve hours, changing it several times. Many gardeners advise to warm up the seed fund a couple of months before planting. Before sowing, the seeds are disinfected with a manganese solution and additionally treated with a drug that enhances growth.

Rules for growing seedlings at home

For this, it is recommended to use peat pots, paper or plastic cups, cassettes.

Seedlings do not tolerate transplanting well, for this reason, picking must be excluded.

To create ideal conditions, the soil is best composed of garden or turf soil, adding humus or sawdust. Prepared seeds are planted in a couple of pieces in each container to a depth of about one and a half centimeters. The pots are placed on a pallet, sprayed with water, covered with foil or a piece of glass, and placed in a warm place.

So that the sprouts do not stretch too much, the temperature in the room should be within twenty degrees of heat for several days. Then it is allowed to increase it by three to four degrees. It is also necessary to completely exclude drafts, which are contraindicated for seedlings.

Seedlings are transferred to well-lit places; on cloudy days, additional supplementary lighting is organized.

Watering is carried out every two days, for which they use rain or boiled water. Before transplanting seedlings into the ground, they begin to harden it by opening a window or taking containers outside for several hours.

If necessary, seedlings can be fed using complex mineral formulations. But you have to make sure that the solution does not get on the sprouts themselves.

The main reasons why cucumber seeds do not germinate

The most common are the following:

  • low temperature conditions of the soil;
  • great depth to which the seeds were embedded;
  • the ground is heavy and dense enough;
  • dry soil;
  • severe waterlogging;
  • the use of numerous methods of preparing seeds for sowing;
  • violation of storage conditions for seed.

What to do if the cucumbers did not sprout

If you did everything correctly and avoided the main mistakes mentioned above, but cucumber seeds still did not please you with their good germination within two weeks, it is best to reseed them. It should also be remembered that cucumbers respond well to organic fertilized soil. It is recommended to add a certain amount of humus to the natural soil during new preparation.

Naturally, everything seems simple and straightforward. But anything can happen, and if you did not get on an auspicious day, you should not panic. Plants can be saved by covering them with special material or polyethylene. Please be aware that the planting dates given here are not final - in each region they are adjusted by climatic conditions. Therefore, your own growing experience should not be discounted!

Sowing seeds at home can be carried out from the end of February. If you are growing varietal cucumbers in the open field, then, most likely, you harvest the seeds of the varieties you like in advance. With proper storage, planting material for cucumbers can last up to 8-10 years, but the best and most reliable seeds are those aged for 2-3 years. Experienced gardeners and farmers recommend planting them. When storing cucumber seeds for a long time, it is important to observe two rules: the air temperature in the room must be at least 200C, and the air itself must be dry. Before planting in the ground, the grains are subject to mandatory sorting, soaking in disinfecting solutions and hardening. The statistics of surveys conducted among summer residents suggests that at home the best cucumber seedlings are obtained from the seeds of self-pollinating hybrids. This does not mean that planting seeds harvested from our own crops is futile, just a little more tinkering with them.

How to properly grow cucumber seedlings on the window so that it does not stretch out

There are undoubted advantages in the seedling cultivation method:

  • Increased fruiting period
  • Guaranteed yield in cold areas
  • Getting early production.

It should be noted right away that a delicate cucumber is extremely painful for transplants. Diving is simply contraindicated for him.

Land preparation

Vines with edible fruits need light, but moisture-consuming soils. In addition, the soil mixture must be breathable and drained. Mineral and organic composition is introduced in accordance with the standard.

Some gardeners are of the opinion that if the cucumber seedlings ripen quickly enough, then additional feeding is not needed before transplanting. It is quite enough if the sowing is carried out in sufficiently fertilized soil.

Summer residents who do not have sufficient experience, as well as gardeners who want to reduce preparatory work, purchase disinfected mixtures at retail outlets. Those who like to tinker with the ground are pleased to prepare the necessary soil on their own.

In the standard order, 4 ingredients are included in the soil mixture:

  1. Sand
  2. Mature compost
  3. Leaf land
  4. Horse peat.

In the absence of peat, they often do without it. Homemade mixture is disinfected by freezing, calcining, steaming. After the disinfection process, nutrients are added for rapid root formation. It is also necessary to add drugs that suppress pathogenic fungi and microflora.

A glass of ash, 2 tablespoons of phosphorus fertilizer, 3 tablespoons of nitrophosphate are added to a bucket of prepared soil.

Also, agronomists advise to carry out treatment with biofungicides: Fitosporin, Trichodermin.

Seed preparation

In addition to the soil, seed is also subject to preparation. Presowing preparation increases the yield, makes plants more resistant to stress, and accelerates germination.

Correct storage of the material guarantees its suitability for 10 years. The highest quality seeds are 4 years old.

When self-collecting seeds, the following points are always taken into account:

  • Annual seeds do not guarantee generous yields
  • Varietal samples are repeated according to the yield of the year in which they were harvested.

Packaged sunflower seeds come for sale mostly processed. Your own seeds need pre-planting preparation.

  • Disinfection... The seeds are kept in a manganese solution.
  • Soak... The seed nodule is placed in a humid environment until pecking.
  • Hardening... For two days, a wet bundle with seeds is kept in a refrigerator at zero temperature, after which it is immediately planted.


After completing the preparatory work, they begin sowing. The containers are filled with soil mixture to the level of 2/3 of the height, having previously provided them with drainage. They carry out generous watering, allow excess moisture to drain, and the soil to ripen.

The soil ready for planting should be crumbly, moist, but not sticky.

A couple of seeds are placed in the center of each container and sprinkled with the remaining soil or sand. The powder is easily compacted with a finger and slightly moisturized.

The container with plantings is covered with a film, arranged in a room with a temperature of + 26 ... + 28 ° С.

First shoots, what to do

When sprouts appear and cotyledon leaves begin to open, the temperature drops to + 20 ... + 22 ° С during the day, and 4-5 degrees lower at night. In accordance with the ambient air, the soil must also be warmed up.

Usually, cucumber shoots are not long in coming and are shown on 3-5 days. After mass germination, containers with seedlings are rearranged to the most lighted places.

How to grow cucumber seedlings: watering, feeding and hardening

Seedlings of cucumbers in the greenhouse do not need to be supplemented - the plants are already powerful and stunted.

When the cotyledons of all plants fully open, they are first watered with warm, settled water. It is best to do this with a teaspoon so as not to accidentally wash the seedlings out of the soil.

Cucumber seedlings are watered in the morning every other day or two and only with warm, clean water. I advise you to use magnetic or melted water. You need to water generously, but try to keep the water out of the leaves.

Small cucumbers respond well to watering with a very weak solution of potassium permanganate.

Top dressing of cucumber seedlings is usually combined with watering.

The first time the plants are fed 1.5-2 weeks after full germination, that is, at the stage of 1-2 true leaves. The next top dressing is done 2-3 days before planting in the ground.

In one of the dressings, I recommend using a complex mineral fertilizer - nitrophoska, Aquarin, Solution. The solution is prepared at the rate of a teaspoon per 5 liters of water. The next time the plants are given some kind of organic fertilizer - BIUD (1:20), mullein (1: 15-20), chicken droppings (1: 25-30).

If you fill the seedling medium well with fertilizers and the plants develop normally, you can skip fertilizing with organic fertilizers.

In the first feeding for every 4-5 plants, a glass of nutrient solution is consumed, and in the second - two.

Regardless of whether you use top dressing or not, every 7-10 days, it is advisable to water the seedlings of cucumbers with a solution of Black Yeast or Rizoplan (1-2 tablespoons per liter of water) and spray with Epin.

After disembarking on an open bed, for the first 1-2 weeks, the cucumbers are covered with a film or cut off bottles from under the water

After such procedures, the plants show great resistance to temperature extremes. They also tolerate poor lighting conditions on a windowsill more easily.

A week before moving to permanent residence, they begin to harden the cucumber seedlings. Plants are taken out onto an unglazed balcony or a window is opened - they are taught to fresh cool air and direct sunlight.

It is important that during hardening the seedlings are not exposed to drafts.

A good seedling ready for planting has a vigorous appearance, short internodes, intense green color and 2-4 true leaves. In this case, the roots of the seedlings entwine the entire inner space of the seedling containers.

There are many schemes for planting cucumbers in the ground: ordinary, tape, square-nested. You can find out more about them here. We usually place cucumber seedlings in the garden so that during a cold snap it is convenient to cover it with a film or non-woven.

Cucumbers do not tolerate transplanting well - try to carry out transshipment from pots without disturbing the earthen coma.

The landing site is prepared in advance. Fertilizers are applied to the prepared pits and watered with a hot pink solution of potassium permanganate. After planting, the soil around the plants is mulched to avoid crust formation. If these conditions are met and the temperature is favorable, the seedlings will take root quickly and without problems..

How I grow cucumber seedlings in April in a cold greenhouse, I told and showed in the video.

Seedling care

For seedlings to grow healthy and strong, they need constant care.


Seedlings of cucumbers require frequent watering: either a little every day, or in large quantities every 2-3 days. The soil in the cups should be neither dry nor too wet. Water for irrigation is taken warm (at least 25 ° C), from cold water plants can get sick.

Top dressing

It is carried out after the appearance of the first true leaf (5 g of urea or ammonium nitrate per 1 liter of water) and then after 1.5-2 weeks with complex fertilizer for seedlings. Cucumbers respond well to foliar feeding on the leaf - fertilizers reach the plant faster.

In the case of hot weather, foliar feeding is undesirable, since the seedlings usually stand on a window or on a loggia / veranda and are well lit by the sun - moist young leaves can get burns.


It can be carried out when the sprouts have already grown and become stronger, then their roots will not suffer. Loosening should be very careful, not close to the stems.


A week before planting in the greenhouse, the seedlings of cucumbers are hardened by taking them outside (or opening a window on the loggias), first for 2-3 hours, then for several hours, for the whole day. Before planting, the seedlings can be left outside overnight.

When hardening, do not leave seedlings in direct sunlight - this can destroy them.

Planting cucumbers for seedlings

The dates have been calculated, the containers have been selected, now you can start planting. This work has several stages. Violation of agrotechnical standards on one of them can ruin the whole process, as a result, seedlings of poor quality will be obtained or not at all.

Seed treatment before sowing

In most cases, expensive seeds of varieties and hybrids are processed by the manufacturer, and therefore do not require preparation. Information about this is indicated on the bags, so read everything carefully before sowing. Knowing the weight of the seeds and the number of pieces in the package can provide important information. So, 1 g of long-fruited varieties contain about 30 seeds, and 1 g of short-fruited ones - about 44 pieces.

If the seeds are not processed, you need to prepare them for sowing yourself. For this, the following activities are carried out:

  1. Soak for 10-15 minutes in a saline solution (a tablespoon of table salt per liter of water). The seeds that have settled to the bottom are collected, and the rest are thrown away.
  2. Soak to swell the shell. For this, a bag of gauze is made, the selected seeds are poured inside, soaked and kept for a month at a temperature of about 30 ° C. The bag must be regularly moistened, not allowing it to dry out.
  3. They are treated against fungi with fungicides according to the instructions or with a red manganese solution for 15 minutes, then washed in running water and dried.

If desired, you can treat the seeds with a growth stimulant, for example, with the drug "Epin-extra". However, many gardeners ignore this recommendation and, according to their assurances, do not lose anything. Therefore, the use of growth stimulants is optional.

3 days before sowing the seeds, they are placed in wet gauze and put into the refrigerator, where they are kept at a temperature of 0 ... 2 ° C. When the day of sowing comes, they are taken out, placed in the ground without drying.

Preparation of soil for seedlings

It is undesirable to take unprepared soil from the garden: for a year it has become depleted, it may contain pathogens of diseases dangerous to the plant. Better to buy a ready-made mixture or make it yourself. In the first case, the compositions "Gumimax", "Hera" or the like are suitable.

In the second case, you can use the following recipe:

  1. Take in equal parts leaf or turf soil, rotted peat and humus.
  2. Add one part washed river sand.
  3. For 10 kg of the finished mixture, add a teaspoon of urea and potassium sulfate.
  4. Add 20 g of superphosphate and 80 g of wood ash.

Before adding mineral fertilizers, it is better to disinfect the mixture with "Fitosporin" or "Trichodermin", add the rest of the components in a day and start planting.

It is better to prepare soil, peat and sand in summer or autumn, pack it in bags and store it in a barn.

Features of sowing cucumbers

Sowing cucumber seeds for seedlings is not difficult. The soil mixture is poured into the containers so that 2-3 cm remains to the top, then it is spilled so that the soil is compacted and there are no voids. If necessary, the earth is filled up.

A hole is made in the center of the container, it is possible with a pencil, 2-3 cm deep. Seeds prepared in advance are placed inside and covered with the same soil mixture. If the soil in the cups was moistened, then watering on the day of sowing is not needed, but if the soil is dry, it is moistened. Until the seeds germinate, the containers are kept under the film, then it is removed.

It is better to water with a spray, so as not to wash out the soil and not expose the seeds.

Possible problems with seedlings and their solutions

The process of growing cucumber seedlings does not always go smoothly. Let's consider the main problems and methods of their elimination:

Such a nuisance occurs due to poor conditions of detention. The main factors are insufficient light, high temperatures, and excessive watering.

Install additional lighting for the plants, reduce the indoor temperature to 15-18 degrees, reduce the frequency and volume of watering. Sometimes the seedlings are pulled out in too tight pots or because of the increased acidity of the soil.

Yellowing of seedlings can occur due to a lack of light, improper watering (excessive moisture or drought), lack of nutrients, fungal infections, hypothermia, root damage, sunburn.

Water the plants in moderation, keep them in a bright place without direct sunlight, feed them in a timely manner, avoid picking by planting in separate containers, and then the seedlings will grow strong and healthy.

All diseases are based on non-observance of agricultural practices. The risk increases if you refuse to disinfect seeds and soil, watering with cold water, too high or low air humidity, exposure to drafts and temperature extremes. Most often, seedlings are affected by fungal diseases.

At the first signs, the plant must be treated with Topaz, Fitosporin or another fungicide. Viral and bacterial diseases are practically not amenable to treatment; diseased seedlings are destroyed.
