. Planting periods in the open ground. When planting corn in a particular climatic zone, you can get a good harvest of this valuable delicacy. Growing this culture is easy. It does not require special attention, and in the second half of the summer season, it will delight with its tasty fruits.
Features of the
type Given that corn is home to South America, the normal development of a plant is possible only with sufficient heat and light. Depending on the climatic conditions, the time of planting the culture varies significantly in different regions. At the beginning of the growing season, for two months, the plant practically does not use natural resources of the plant. As a result, growth is very slow, and the question arises of changing the seeding time.
The soil temperature should be at least 10 ° C.On average, the vegetative period from the moment of emergence to full maturity of the cob lasts from 70 to 120 days. With this in mind, it is necessary to correctly calculate the time when to sow corn for seedlings. Today, various hybrids are available that have a short growing season and are resistant to cold. They are great for growing in the northern regions of Russia.

Getting a crop a few weeks earlier than usual is very important for areas where spring comes late and summer is very short. Seedlings planting method allows the fruit to ripen before the onset of cold weather. He enjoys particular popularity in Siberia, the Urals, and the Far East.
The locals in the northern regions know well when to plant corn on seedlings, sowing seeds a month before transplanting seedlings into open ground. Cultivation is carried out as follows:
- Given that the plant prefers breathable, loose soil, the substrate is prepared from mixed in equal parts of turf land and compost. Using a standard peat mixture for vegetables, it will be necessary to feed twice during the growing process.
- Fungicide-treated seeds are first germinated on wet gauze or filtered paper.
- After they are hatching, they are planted in prepared peat pots with a substrate of 3 seeds in each to a depth of 3 cm. From above they are covered with a film, removing it only after the emergence of shoots.
- When 3 to 4 true leaves are formed on the sprouts, the seedlings are placed on a warm place illuminated by the sun.
Transplanting seedlings to a permanent place.
When warm weather is established, when night frosts stop, seedlings are transplanted into open ground.
Corn cannot be allowed to grow in pots. This delays further development and adversely affects the future harvest.
In order to accelerate the formation of secondary roots, the planting depth is made a bit more. After planting seedlings in the ground it is necessary to feed it with mineral and organic fertilizers. For this purpose, humus and compost are well suited. The composition of mineral fertilizers must necessarily include potassium.
Damage to the roots should be avoided when corn is planted. This culture is very sensitive to the slightest damage to the root system. Therefore, to grow seedlings, it is best to use peat pots, which are simply dug into the soil.

The time when planting corn in open ground depends on the weather conditions typical for the growing region.
There are several natural zones in the country - steppe, forest-steppe and forest. Accordingly, the sowing time will be different. In the steppe zone, planting of corn begins in mid-April, in the forest-steppe zone - at the end. The climate of the forest zone is more severe, so it is recommended to sow in early May. The timing of when to plant corn in the spring in Ukraine is conditional. If the soil is well warmed( up to 10 degrees of heat and above), you can engage in sowing.
A large amount of plant residues on the soil surface makes it difficult for heat to pass. Land for planting corn must be cleared of debris.
In the middle lane and in the south of Russia
The optimal time when planting corn in open ground in areas of the Moscow region is mid-May. At this time, almost all heat-loving crops are planted. Many gardeners sow cold-resistant hybrids already at the beginning of the month, but this requires a temporary shelter of film. In the south of the country, sowing is carried out when the average daily temperature becomes more than 5 ° C.Usually this period falls on the end of April - the beginning of May. It is safer to plant corn when the air temperature is constantly warm and the soil warms up to 10–12 ° C.
