"Swing" for seedlings

Photo 1. Swing for seedlings

As you know, there are many crops, high-quality seedlings of which are quite difficult to obtain indoors. This is, first of all, our beloved queen of the garden - cabbage. Also, for example, I have never been able to achieve success in growing seedlings of kochia and asters at home.

There are several reasons for this. First of all, it is a lack of light. Well, where in city apartments with double windows dusty after winter (especially in the so-called "wells") there can be enough light for such light-loving crops!

The next reason is the temperature regime. All of the aforementioned cultures will not develop normally at our 25 degrees apartment, especially with a lack of light. The phrase from the anecdote immediately comes to mind: "Vasya, open the window, Vasya, close the window" ...

And another important reason is humidity. The air in city apartments is very dry. Now the so-called evaporators - air humidifiers have appeared on sale, but I do not have such a device yet, so every day during the seedling period I start with spraying all crops. The main thing here is not to overdo it, especially at first, and even to the "black leg" not far.

In addition to all the above-mentioned objective reasons, I also have one more, indirect, and, I think, not one of me - a catastrophic lack of space on window sills, seedling racks, hanging shelves ... What gardeners do not come up with, but there is still no place enough.

For many years, on long winter evenings, I racked my brains over how to somehow defuse the density of crops on the windowsill, as well as create optimal conditions for growing light-loving crops. I washed the windows in February to make it even a little lighter, put foil screens to reflect light, placed bowls with cabbage and asters seedlings between the windows - it is lighter and cooler there.

Two years ago I even made a light for seedlings. All the same, she did not achieve the desired result. The light of fluorescent lamps (even a special Osram Fluora) is very different from sunlight. Both asters and cabbage had to be sown at the end of April in a heated greenhouse, where the seedlings grew of a completely different quality. But late April is pretty late for cabbage. At least June cabbage, having sown seeds at the end of April, in June you are unlikely to eat ...

Last winter I once again thought about this question. I read a lot of literature. With some irritation, I saw that early cabbage is not recommended to grow in our region if you do not have a heated greenhouse.

Since I go to the dacha all year round - to feed the birds and get goat's milk for a child, I noticed that already in February the sun begins to warm in a completely spring-like way, and, reflecting from the snow, and generally blinding. But the temperature is still low. Unfortunately, I don't have any installations for heating greenhouses, so I decided to do the following. In the last decade of March, I covered the pepper greenhouse with Svetlitsa film - by the way, I recommend it to everyone, I haven't found anything better for myself yet - and filled the beds with first-year manure.

A week later I arrived - it smells in the greenhouse in spring! But I already know from experience - do not put manure, and the earth thaws very slowly after winter. Therefore, I did this: I put two strong ropes through the ridge of the greenhouse and tied the ends of each to make a loop. Then, through these two loops, I passed a piece of a regular board. It turned out like this "swing" for seedlings (see photo 1).

That year I made them small, because the first time I built something like that. At the same time, I put arcs on one of the ridges of the greenhouse and covered it with spunbond - let the soil warm up.

I chose three crops for sowing - white cabbage (early - a hybrid Kazachok F1 and a Podarok variety), asters of the Princess variety and kokhia seeds (samosbor). The soil for the seedlings was made by itself: one part - the earth from the home "worm", one part - dung humus and one part - coconut substrate with sand.

Before filling the seedling containers with soil, I thought about watering - I can come to the dacha only once a week. I solved the problem with a regular piece of jersey, tearing it into long narrow strips.

She laid one part of the improvised wick along the bottom of the seedling container, and left the other to hang freely. And so she did with each of the three bowls. Then she filled them with earth almost flush with the edge, so that there was no unnecessary darkening from the edges of the container. She sprinkled aster seeds just a little with coconut substrate, sowed cabbage and kohija deeper.

As soon as I finished sowing, I put all the bowls on a swing, and placed a small bucket of water in the center, into which I lowered the wicks from each seedling container. She wrapped the whole structure with SUF17 spunbond in several layers and went home. A week later I arrived, unwound the spunbonded "cocoon" and could not believe my eyes - the first loops appeared! And this is how the seedlings looked like two weeks after sowing (see photo 2).

I cannot say that the seedlings were friendly, but they were. And they had enough light, water, and heat. But it was still only mid-April! On April 19, in the already more or less warmed up soil in a greenhouse, I made the main sowing of cold-resistant crops - seeds of all types of cabbage that I bought for the season - white cabbage of different ripening periods, colored, broccoli, Beijing, kohlrabi and ornamental.

In addition, she sowed asters, radishes, turnips, carrots, beets and lettuce. On April 23, I disassembled the swing, spreading the seedlings from them to the garden bed in the greenhouse next to the main crops. I threw the ropes on the skate - they will come in handy next year. In this form, the cabbage seedlings from the swing went to their permanent place of residence (see photo 3). And such a cabbage was in the second decade of June (see photo 4).

Photo 5. Cochia

At the end of June, we ate the first head of cabbage of the Kazachok F1 hybrid. Thus, my dream came true to eat early cabbage in June. Of course, high-quality seedlings alone are not enough to get full-fledged forks on time. But this is a completely different topic. In conclusion, I would like to show you a photo of a kochia that has grown from a "swing" (see photo 5), and wish you not to be afraid to experiment. I also want to quote my favorite quatrain (alas, I don’t know the authorship), which helped me to look at many things in a completely different way:

In all matters with maximum difficulty
The approach to the problem is still the same:
Desire is a multitude of possibilities
And reluctance - many reasons ...

In the new season, I wish everyone good results in the beds and in the garden!

Seedlings of cabbage - when to plant seeds for seedlings

That an adult plant, that young seedlings easily tolerate cold weather. Therefore, even a novice gardener can grow cabbage seedlings. Growing them in a polycarbonate greenhouse, which can now be found in almost any summer cottage, you can easily breed strong and healthy seedlings. Therefore, sowing seeds is the most crucial moment. And you need to start growing them on time, so that by the time they are transplanted to a permanent place in open ground, they have already grown well and strong. In order not to damage them during transplantation and at the same time so that they do not overgrow. Overgrown plants adapt worse to new conditions.

When calculating the time of planting seeds, know that seeds germinate in 3-4 days. And it will take another 30-35 days for the seedlings to grow and get stronger before planting in open ground.

The optimum temperature for growing is + 8-10 º at night and + 12-15 º C in the daytime. It will not work to grow strong and healthy plants in an apartment (house), therefore it is better to grow them in closed polycarbonate greenhouses, on a glazed and insulated balcony. But it will not be possible to achieve such temperatures the same everywhere, since in each region spring comes at different times. Much more depends on the variety and type of cabbage itself.

4. Choosing the optimal sowing time for cabbage seedlings

There is no point in sowing cabbage seedlings in early January - it's too early, or at the end of May - it's too late. Every gardener knows this common truth. But, although we know the approximate dates for sowing seeds, sometimes it is quite difficult to determine a specific date. Let's talk about everything in order. Remember:

  • early varieties of cabbage should be sown for seedlings from the beginning of March until about the 25th-28th of the month,
  • seeds of medium varieties can be sown approximately from March 25 to April 25,
  • well, cabbage of late varieties - from the beginning to the 20th of April.

The main thing is to sow on time

If such dates for sowing cabbage seeds seem to you excessively blurred and incomprehensible, then you will appreciate the recommendations from the article When to sow vegetables for seedlings - it describes an algorithm that helps to calculate the optimal sowing time for your conditions.

Well, I will give one more hint: you can determine the time of sowing cabbage for seedlings based on the fact that about 10 days pass from the time of sowing the seeds to the emergence of seedlings (plus or minus a couple of days), and from the emergence of seedlings to the time of planting, about 50-55 days. Based on this, it is necessary to sow cabbage for seedlings 60-65 days before the desired planting in the ground.

Our market, which contains offers from the largest online stores, will help you choose seeds for sowing cabbage for seedlings. Select white cabbage seeds.

Seedlings of cauliflower.

Seedlings of cauliflower.

Growing cabbage seedlings - the process is almost the same for all its types.

But you need to pay your attention to growing cauliflower seedlings ... If a white cabbage seedlings easily tolerates low temperatures and this does not affect the quality and future harvest, then growing cauliflower seedlings under unfavorable temperature conditions, it leads to a decrease in yield, the heads are often small and loose. Average temperature growing cauliflower seedlings 6 - 8 ° C higher than that of white cabbage.

How can you grow cabbage seedlings in a greenhouse

One of the favorite crops of gardeners is cabbage. Despite the fact that this culture is quite capricious, summer residents willingly grow it. Just from fresh cabbage, you can cook delicious cabbage soup or cabbage. Cabbage can be grown not only in vegetable gardens, but also in a greenhouse. How to grow cabbage seedlings in a greenhouse, we'll talk about this.

Features of further care and cultivation of cabbage seedlings

To grow healthy cabbage seedlings at home, you need to create optimal conditions. Otherwise, the seedlings will have an unsightly pale appearance.

Temperature regime

Remember! Cabbage is a cold-resistant plant. The only exception is cauliflower: it needs more room conditions, but it does not tolerate too high temperatures.

As soon as the cabbage seedlings hatch and friendly shoots appear, the temperature of the content must be set in this range (recommended for white cabbage and other types of cabbage, except cauliflower): in the daytime - + 14-18 degrees, and at night - + 8-12 degrees. Such a regime will help curb the excessive growth of the aerial part (prevent it from stretching) and will allow the root system to grow.

Therefore, it is advisable to take out containers with seedlings to a balcony or loggia. Or, if you only have a window sill, then slightly open the windows, setting them to the winter ventilation mode.

In general, as a rule, cabbage seedlings are placed in a greenhouse.

But the seedlings cauliflower It does not tolerate low temperatures well, therefore, for its successful cultivation, the temperature both in the daytime and at night must be 4-6 degrees higher, i.e. in the daytime - + 18-22 degrees, at night - + 14-18 degrees.

Interesting! Cauliflower really comes in different colors, but it got its name not because of this, but because it is the flowers (tightly pressed buds) of this plant that we eat, and not the leaves.


Cabbage is a light-loving crop, so any slight darkening can lead to the death of seedlings. For the full growth of cabbage seedlings, daylight hours should be within 12-15 hours.

Planting containers with seedlings should be placed on the southern windowsill, or at least on the southwest or southeast. And in the evening or morning hours, if possible, provide backlighting phytolamps.

Watering and humidity

Watering the cabbage planted on seedlings should be carried out as the topsoil dries up, avoiding overflow and drying out of the roots. In this case, water should not fall on the leaves.

Note! It is strictly forbidden to water cabbage seedlings with cold water, only warm or at least room temperature. The optimal water for irrigation is rain or melt water. Ordinary running water, passed through a filter and settled for 24-48 hours at home at room temperature, is also suitable for watering cabbage.

Top dressing

Fertilizers must be applied to keep cabbage seedlings strong and healthy. This will help her to develop more actively and fully.

However, if you initially prepared a nutritious soil (with humus or compost, wood ash), then, in principle, no additional fertilizing is required. Of course, if the appearance of the plants does not require the opposite.

Cabbage seedlings are fed in the following order:

  • at the stage of appearance of 2 cotyledonous leaves (7-10 days after germination)
  • 10-14 days after the first (in phase 2 of these leaves)
  • 10-14 days before disembarkation in open ground.

By the way! If you are growing with a pick, then the first top dressing should be done 7-14 days after it was carried out.

First feeding You can do yeast infusion... Dissolve 10 grams of dry yeast in 1 liter of water, add 3-4 tbsp. tablespoons of sugar, let it brew for 4-6 hours and pour under the root.

The second dressing should contain a lot of nitrogen. For example, you can sprinkle with herbal infusion (for example, from nettle) or use mineral fertilizers (for example, ammonium nitrate or urea).

You also do not want to bother, then for feeding cabbage seedlings it is recommended to use complex mineral fertilizers containing nitrogen, phosphorus and potassium in equal proportions. Or prepare such a top dressing from various fertilizers, for example, taking 3-4 g of urea, 3-4 g of superphosphate and 3 g of potassium sulfate per 1 liter.
