Despite all the difficulties associated with growing cabbage seedlings, many gardeners still heroically wish to overcome them. And this is no coincidence, since self-grown seedlings bring special joy and faith in their own strength. True, in the case of cabbage, those who live on their own land and have the opportunity to create the necessary conditions for seedlings are most fortunate. City dwellers of multi-storey buildings, especially if they do not have balconies and loggias, are less fortunate, since for them growing normal cabbage seedlings is an almost impossible task. Therefore, most often complaints about the fact that it withers cabbage seedlings, come precisely from residents of apartments with central heating, who, with all their desire, are usually not able to provide cabbage seedlings with the conditions under which it is able to develop normally.
Even if you are not the happy owner of such structures, you can always come up with something on your site: install arcs with double shelter, make improvised greenhouses from scrap materials, and finally, install boxes with seedlings on the veranda, terrace or in any other cool room.
What is needed for cabbage seedlings
What conditions are necessary for cabbage for good health and active growth and development?
- Probably everyone, even novice gardeners, know that cabbage is a cold-resistant plant. After all, not every vegetable crop that came to us from the warm Mediterranean can withstand frosts down to -8 ° C. Young cabbage plants are also comparatively resistant to cold weather, in the seedling phase they can withstand a short-term temperature drop down to -5 ° C.
- At the same time, temperatures from + 16 ° C to + 20 ° C are ideal conditions for growth and development.
- But cabbage tolerates high temperatures very poorly. Already at an air temperature of + 25 ° C and above, it feels depressed, and at + 35 ° it loses its ability to form a head of cabbage, and young seedlings are likely to die.
- Cabbage is also a light-loving plant, it also needs long daylight hours and bright good lighting. With insufficient light levels, seedlings will develop poorly and slowly.
- Cabbage is quite demanding on watering and humidity of both air and soil. But she needs the greatest amount of moisture during the period of head formation.
During the growth of the leaf outlet, the moisture requirement of cabbage is quite moderate. The soil should dry out slightly between watering procedures. True, the complete drying out of the soil can lead to the death of young plants. - Finally, cabbage is the most demanding of all vegetable crops for nutrition. She needs constant regular feeding, without which a good harvest cannot be obtained. But the need for them appears mainly after the development of 5-6 true leaves, that is, after planting cabbage seedlings in open ground. In the very first phase of the development of seedlings, fertilizing is needed in minimal quantities and she can get everything she needs from the nutrient soil in which she was sown.
Causes of wilting
"Why does she wither?" - ask the lovers of cabbage. Now try to imagine or even check in practice what temperature is formed in a room of an apartment with central heating on the sunny windowsill of a south-facing window.It is in these conditions that cabbage seedlings most often live, since it is also a light-loving plant. For some time she still holds on with her last strength, but then sooner or later she dies, unable to cope with adverse conditions.
And novice gardeners cannot understand what happened, because they did everything, as with other vegetables. They placed the seedlings in a warm place, provided the maximum amount of light, even supplemented them with special lamps. Water abundantly, as required by cabbage. And she still disappears. Tomatoes and peppers grow side by side in the same conditions and do great, but cabbage does not.
Perhaps they even sow seeds for seedlings over and over again, but the situation repeats itself and no one can quite figure out what to do.
It is often remembered that cabbage is very susceptible to various fungal diseases, and its seeds must be treated before sowing with special fungicides, in extreme cases, with a solution of potassium permanganate. If this has not been done, then they usually calm down, thinking that they have finally found the reason for the failures with cabbage, and next year everything will definitely work out. But even the next year, after all the seed treatments and additional spilling of seedlings with biofungicides, nothing changes, the seedlings again wither and die.
But the fact is that all varieties of cabbage, especially white-headed species, have one more feature in the care at the seedling stage. Cabbage seeds germinate well, quickly and amicably enough at a temperature of about + 20 ° C and even higher.
For white cabbage, it is better if the temperature does not exceed + 8 ° C + 10 ° C, for a more thermophilic cauliflower, the maximum can rise to + 12 ° C + 15 ° C, but for any cabbage this period of lowering the temperature is strictly required at least at night time. Otherwise, we can assume that your seedlings are gone again. And, unfortunately, this will happen sooner or later. Therefore, if you grow cabbage seedlings in an apartment and you have a balcony, even unglazed, then you need to do the following. Immediately after the emergence of seedlings, build a frost protection for the seedlings from several layers of film and, without hesitation, put it on the balcony for 5-10 days.
Difficulties after transplant
But even if you go through this first stage of cabbage development correctly, then you will face several more tests. One of the most common problems when growing cabbage is its unhealthy appearance after being transplanted into other containers or outdoors. As a rule, after this procedure, the lower leaves of cabbage seedlings turn yellow, and she herself withers to one degree or another. This is a completely natural reaction of plants to some damage to the roots, which is inevitable when transplanting seedlings.
It is also better to replant in very well shed soil, practically liquid mud. Several days after transplanting, the seedlings must be shaded from the bright sun and kept in warm conditions at a temperature of about + 20 ° C.
This can be done when picking seedlings in separate pots in the rooms. On the street, it is enough just to protect it from the bright sun until it fully survives in new conditions.
Of course, the sight of withering cabbage seedlings cannot but torment the hearts of the gardener, but in the case of its transplant, you can be sure that in a few days it will definitely recover and begin to develop further with renewed vigor.True, this will happen only on condition that a few days after transplanting, the cabbage seedlings will be returned to cool conditions, preferably not higher than + 16 ° С- + 18 ° С.
For these purposes, you can simply open the window for ventilation and put the seedlings under a stream of cool air. You should not be very afraid of drafts, for cabbage stuffy and hot air is much more dangerous. Nevertheless, if the seedlings were overly pampered from the first days of life, then drafts can be dangerous for them. But the best thing is to find a place for her with a constantly cool temperature, ideally if there is a difference of five to ten degrees between day and night temperatures.
Solution to the problem
So what happens in 90% of cases with cabbage seedlings? From the very first hours, she finds herself in unfavorable conditions that are too warm for herself. As a result, the root system is not able to fully develop, the stems are strongly stretched, and the plant immunity drops to zero. As a result, even the slightest mistakes in care, which in the normal state of the plant would not have noticed, lead to an even greater deterioration in the condition of the seedlings. It begins to fade, turn yellow, sometimes immediately fall.
And what about the remaining 10%? They just represent those cases when the seedlings were affected by any infections or pests. Perhaps it was planted in soil with a more acidic reaction than it needs.
If all agronomic measures for seed processing and care for cabbage seedlings are carried out on time and correctly, then such situations can be almost excluded. After all, cabbage, like all vegetables, strives to grow, develop and delight with its harvest. It is only necessary to take into account its peculiar requirements and everything will be in order.
