Conditions for growing corn
Heavy, crusty soils are not suitable for corn. She prefers loose and fertile soil: light and medium loamy, breathable and moisture-intensive, but does not tolerate excess moisture. The area allocated for corn should be well lit and warmed up by the sun.
Sowing corn for seedlings
If you grow corn seedlings, seeds should be sown in late April — early May. After frost (about June 10), the grown seedlings can already be planted in open ground (it is good to combine these works with planting seedlings of cucumbers ). It is desirable that the root system has mastered the entire container, but do not keep the seedlings at home for longer than the 3rd true leaf phase.
Already 2-3 weeks after the emergence of seedlings, corn seedlings are ready for planting in a permanent place. You should not let her change in a pot — this delays the development of plants and affects the yield. Planting depth should be slightly more than the one at which she grew up. This will improve plant survival and stimulate the formation of secondary roots. Planted carefully so that the root ball does not crumble, then the plants are watered and spud.
Sowing corn in open ground
Before sowing corn in open ground, corn seeds are heated for 4–5 days in the sun, and then soaked in warm water to speed up germination. Corn germinates at temperatures above +8 °C. Seedlings of corn are able to endure small frosts, in a week they already grow new leaves.
Based on this, it is necessary to determine the timing of sowing in open ground. For tall varieties, the row spacing is made at least 65–70 cm, the distance in the row is 35 cm. 3–4 grains are sown in each nest.
Japanese corn with decorative leaves is sometimes planted in flower beds.
Corn care after planting
At first, corn grows very slowly, so the aisles must be constantly weeded.
Corn loves organic fertilizers (humus, compost), but the need for mineral nutrition, especially potassium, is also great. Compost is applied at the rate of 5 kg per 1 sq. m. All mineral fertilizers are used in the spring, before planting. But if you notice that the corn has suddenly stopped growing, feed it with mineral fertilizers: the first time — in mid-June, the second — in the first decade of July. The plant uses the bulk of nutrients in the second half of summer.
Maize care includes 2–3 loosening of row spacings, and the higher the plants, the shallower the soil must be cultivated, preventing damage to the roots. On plantings, it is possible to artificially pollinate plants, transferring pollen from male flowers to female ones. This operation is repeated several times.
In wet weather, corn often develops side shoots that need to be removed. Although the plant tolerates drought, it is still recommended not to allow strong fluctuations in humidity. It consumes the most moisture shortly before it starts throwing panicles.

Tips for growing corn
- A bed of corn will serve as a good stage for cucumbers . It is placed on the windward side — where the wind most often blows on cucumbers. Carbon dioxide is actively released from the soil, which cucumbers require a lot for photosynthesis. The «fence» of corn prevents the dissipation of carbon dioxide from the surface layer of air and helps cucumbers develop better.
- Often they sow corn and pumpkin for seedlings in one pot and also plant them together in the garden (the period in this case is determined by the readiness of the pumpkin for planting in a permanent place). Corn roots quickly wrap around a clod of earth in a pot and protect pumpkin roots during transplantation. In the future, the plants do not interfere with each other, on the contrary, the pumpkin, covering the soil with its wide leaves, does not allow it to dry out and compact.
Corn pest control
Corn is one of the most attractive crops for the wireworm (larvae of the click beetle) . They just appear on the white light in late May — early June, they are very voracious and capable of destroying young plants. Therefore, during spring digging (enough for a shovel bayonet), you need to carefully select and destroy pests, add lime or ash to acidic soil , and treat heavily contaminated soil with a special preparation.
If you do not want to mess with «chemistry» once again, you can go the other way. Cut into large slices potatoes, carrots, beets and bury to a depth of 10–15 cm. Check the baits every 3–4 days and destroy the wireworms that have gathered in them. To make it convenient to get the traps out of the ground, stick wooden twigs into them before burying them.
Depending on the variety , from two to four ears are formed on one plant. They are broken out at the stage of milky-wax ripeness. It is very easy to determine this period: if you press your fingernail on an amber-colored grain and milky juice splashes out of it, then the corn can be harvested. Since this period does not last long, in order to extend the time of harvesting the cobs, you can sow corn at several times.
Sweet corn grows well not only in the south of the country, but also in more northern regions, however, its ripening period should not be long.
