Why spring and summer. Why are plants planted in the spring? Solar activity and heat

From the beginning of spring, people involved in gardening begin a hot season. Some plants are sown at home as early as early March, so that they have time to get stronger by the time they are planted in open ground in May - June, when the earth warms up properly. It's about mainly about heat-loving species, whose homeland is warmer latitudes than those in which they are sown by people. Tomatoes, cucumbers, zucchini, and many other plants familiar to the gardener are sown in advance, at the very beginning of spring.

But shrubs and fruit seedlings are also planted mainly in spring. Why do people act this way? People who are not too keen on gardening and horticulture may well have such a question.

Solar activity and heat

In autumn, experienced people do not even plant onions on the windowsill. And all because the short daylight hours do not contribute to photosynthesis and vegetation of the plant. Germination, and even more so, flowering, fruiting require strength from him. The sun gives energy to plants. When it is not enough, it is necessary either to create artificial lighting, or to refuse to grow plants. In most cases, people simply postpone such tasks to a more favorable time for this. At the end of winter, daylight hours increase rapidly, solar energy becomes enough, you can sow the first seeds. In most regions of Russia, snow still lies at this time, so the plants are planted in containers and kept at home or on insulated loggias. As soon as the snow melts and the soil warms up enough, it makes sense to check the weather forecast for the coming weeks and make sure that no frost is expected. After that, the plants can be planted in open ground.

Can plants be planted in summer?

Spring is auspicious time when plants have enough solar activity, and melted snow provides a sufficient amount of moisture. So planting better in spring- they take root well, tolerate the stress of transplantation more easily, grow vigorously. Many crops can be planted in the summer, providing additional watering if necessary. Fertilizers play an important role, you should not forget about them either. But in summer, the transplant is more traumatic, and the seeds show a lower percentage of germination. In addition, crops planted in the summer may not have time to bring a harvest. It takes quite a long time for the fruits to ripen, and summer in Russia passes quickly.

Cucumbers planted in the form of seeds immediately in the ground will not have time to bear fruit if they are planted in late spring or summer. But planted in containers in early spring the plants will have time to go through the growing season, breed and provide the gardener with a good harvest.

Why are some shrubs and trees planted in autumn?

If speak about fruit trees and berry bushes, some ornamental plants - for example, a rose, then they can be planted in the fall. In this case, they work with seedlings in late autumn, but not before frost, so that they have at least a week or two to adapt and prepare for winter. During this time, the plants have time to gain a foothold in the ground, then they simply hibernate under the snow. If wintering goes well, buds bloom in spring at shrubs or trees.

At autumn planting perennial gets more time to adapt, which means it will bloom and bear fruit a season earlier than its counterparts planted in the spring. The practice of gardeners shows that in some cases autumn planting is more effective than spring planting. But there is a risk of plant death from frost or lack of moisture. When planting in autumn, seedlings should be insulated for the winter, although each variety has its own recommendations.

Interesting fact: other crops are sown in autumn. In particular, there are plantings of wheat, called winter wheat - they are just sown in the fall. Many farms use both winter and spring planting methods, selecting crops for which one or another sowing option is recommended.

Thus, plants are planted in the spring due to the fact that they take root better during this period. The spring sun gives them energy for germination and vegetation, and then they have the whole summer for flowering and fruiting. Spring planting is most promising for those who want to get a big harvest, or grow beautiful flowers. In northern latitudes, you have to start growing seedlings at home, because spring does not provide enough heat for planting in the ground.

But despite all the inconvenience that may be associated with this, gardeners still adhere to this scheme for heat-loving plants and for crops that need a long time to form fruits. The spring sun powerfully spurs the vegetation, and plant lovers do not want to miss this favorable period.

I've always been the type of person who thinks the sun does the most damage in summer time . But what was my surprise when my first sunburn I received in the spring.

The problem is that many people are confident in the safety of the spring sun, so they neglect sunscreen. In fact, the spring sun radiates no less ultraviolet than summer. Getting on unprotected skin, it can provoke it premature aging, burns and various diseases. Do not forget that ultraviolet also enters the retina, which can lead to its burn. But this does not mean that in clear weather you need to sit at home and wait for the sun to go down. In the spring, subject to all safety rules, it is advisable to spend as much time as possible in the sun to replenish supply of vitamins which were lacking in winter time.

Why in the spring and summer outside the city, in the country, where fresh air and spring water, many again sneeze and cough, as in a city apartment? Spring ... Naturally, everyone normal person this couple evokes the most pleasant emotions: the sun, the first greenery, the birds sing. What else, tell me, does an average Belarusian, exhausted by long halads, need to be happy? By the way, there is a group of people who are not happy with the arrival of spring, and then summer, on the contrary, they are worried. These pakutniks are allergic, who react to the awakening of nature with an exacerbation of the disease. It is called "Hay fever", or palinozam. What a misfortune - an allergy! Allergy is perhaps the most common disease. No wonder it is called the disease of the new century. The statistics are sad: every fifth inhabitant of our planet suffers from it. This is very strange, because air washers have already been invented that can solve all problems.

But if we take into account that not everyone who sneezes and coughs has the appropriate records in the medical card, then the dimensions of this phenomenon look velizar. Allergens - those same irritants that stuff up the nose, watery eyes and itches the whole body - everyone has their own. and we know them well. Therefore, in advance by phone, we ask you to close the cat on the balcony if we are visiting. We do not use chocolate, oranges and are treated only with those medicines that have been tested many times. and yet, from time to time, allergy symptoms remind of themselves. Without warning. For no specific reason. And most importantly, where they can least be expected, including at home, in the country. Palinosis with enviable regularity comes to allergy sufferers in the spring, accompanies them in the summer and says goodbye only in the fall. By the way, this disease selects each victim purposefully. Someone already reacts in April-May to the smells that come from the inflorescences of birch, alder, hazel. The second suffers in June, when they "dust" cereal herbs, the third - in July-August, when the weed begins to bloom - ambrosia, wormwood and quinoa. For those who are especially unlucky, they can prachhats and prapkats (these are the most frequent manifestations of palinosis) all spring and summer.

What kind of torment this is, perhaps only the allergy sufferers themselves know. The food of the gods causes asthma An allergic reaction to plants that bloom, according to doctors, is one of the most dangerous diseases. It reduces the immunity of a person, makes him dependent on medicines, from the weather, even from the breath of the wind. At least last year in August in Zaporozhye, about 200 people were admitted to the ambulance in one night with complaints of unforeseen suffocation. Later it became known that the ragweed pollen, which was raised into the air, was to blame for everything. strong wind. People almost simultaneously reacted to the pollen, which deprived them of the ability to breathe normally. The fact is that ambrosia, which is also called the "food of the gods", does not grow at all in heavenly crowns, but on sinful earth, and contains the most malicious allergens - provocateurs of bronchial asthma. Ambrosia begins blooming in August and “poisons” the entire area almost until the first frost.
