Planting broccoli seedlings

Cabbage has long been one of the important components of the human diet. There are many varieties of the popular vegetable, but each has its own subtleties when grown by seed. How is broccoli planted correctly for seedlings and what are the basics of care? Let's analyze the most important points of agricultural technology of culture.

Proper planting broccoli seedlings

Preparatory procedures

Seat selection

Before planting broccoli cabbage for seedlings with seeds, choose a suitable place for growth. Like white-headed species, these varieties prefer to develop in the lighted parts of the garden with little shading in the form of bushes or young trees. Culture does not like closely adjoining groundwater and acidic soil. The recommended alkaline reaction of the earth should be within 6.7-7.5 units. If the indicators are higher, it is advised to alkalize with lime.

Planting a certain culture in one place every year, it is difficult to achieve the productivity of the variety. There are plant species that have the same diseases and pests.

Adverse predecessors

According to the rules of crop rotation, planting seedlings for growing broccoli is prohibited after:

  • radish;
  • watercress;
  • Tomatoes
  • radish;
  • any kind of cabbage.

The culture will not be able to develop normally and give a plentiful harvest in this area for 4 years.

Favorable predecessors:

  • cereals;
  • cucumbers
  • siderates;
  • legumes;
  • potatoes.

Site preparation

In autumn, the future planting site is carefully dug up, weeds are removed and fertilizers are applied. For 1 square. m need about 4.5 kg of manure or compost. In the spring, the plot is again loosened, and 3 weeks before the plants are planted in the ground, the ground is sprayed with a 3% solution of Bordeaux fluid.


For effective growing vegetables you will need high-quality seed. First of all, carefully inspect the seeds, discarding specimens less than 1.5 cm: they have too few nutrients, so it is difficult to get healthy plants.

Before sowing broccoli for seedlings, all seeds are hardened: they are dipped in hot (not more than 50 ° С) water for 3 minutes, after which they are cooled in a cool liquid at the same time. To protect against fungi, the seeds are soaked in a solution of any fungicide (Fitosporina-M, Maxim Dachnik).

The growth activator helps to improve germination - “Epin”, “Zircon” or “Kornevin”. The material is left in the preparation, diluted according to the instructions, for 6-8 hours, after which it is pulled out on a napkin and dried. During the procedure, some grains may float, indicating their non-viability.

Those who plan to grow broccoli cabbage for seedlings should pay attention to the ripening dates. For warmer regions, later varieties are relevant, characterized by a long keeping time and a long growing season - from 120 days or more. In a temperate climate - from 100 days. In Siberia and the Urals, it is better to give preference to early plants that can reach within 3 months.

Growing seedlings

Seedlings in a few weeks

In the domestic climate, cultivation takes place both by direct sowing in the soil, and by seedling method. The latter method allows you to fully control the development of young shoots for several weeks. If you follow the rules, the seedlings will grow strong and healthy.


The planting dates are as follows: after hatching from the grains, the crop will need 30-45 days, therefore, planting in the open ground in the middle lane occurs in late April and early May, and seedlings are advised to be planted in late February and March. In cooler regions, stable heat arrives 3-4 weeks later, so individual dates are corrected.

You can plant broccoli cabbage on seedlings from seeds in a container with prepared soil. An hour before the procedure, the earth is thoroughly irrigated, the water is drained from the pan. Holes are made in the soil, the depth of which should not exceed 1.5 cm and with a distance of 3 cm. 3 grains are placed in each hole, after which they are buried. If everything went right, the sprouts will come out in 5 days.

Before emergence, the box is kept at a temperature of 20 ° C in a shaded place. After biting, the seedlings are rearranged into the light, and heat is reduced to 16 ° C during the day and 11 ° C at night. So that the plants do not get sick with a black leg, they monitor the soil moisture and the presence of ultraviolet radiation. If you provide the culture with a cool development and illumination with a phytolamp, the seedlings will not stretch.


For several weeks, cabbage provide the correct regime. The first top dressing is applied no earlier than 21 days after emergence. At a younger age, organic and mineral fertilizers can cause root burns, which causes diseases and death of crops. Professionals recommend performing the procedure not by watering, but by spraying on a sheet.

After 3 adult plates are formed on the plant, they begin to dive. This optional event is optional, however, most gardeners in such a simple way slow down the development of tops. The disturbed bushes cease to grow foliage and proceed to the regeneration of the underground parts. By the end of the cultivation of seedlings, strong specimens with a developed root system are obtained.

After picking, broccoli seedlings are protected for several days from the sun by building shelter, the temperature in the room is increased to 21 ° C.

Be sure to monitor the soil moisture. At low temperatures, dry ground and insufficient lighting, ailments such as the black leg are activated. To protect the plantings, it is advised to irrigate as needed and water the Fitosporin-M bushes every 3 weeks.


After 30-45 days, the seedlings are ready for planting at a constant place of growth. An indicator of developed bushes are at least 5 adult leaves on the stem and the formed root system. At least 10 days before the start of agricultural work, they harden the culture, gradually lowering the day and night temperatures, and they also accustom them to the rays of the open sun.

After the cultivation of broccoli sprouts has come to an end, they begin to prepare the beds. Between the rows leave 50 cm, and between the holes - 40 cm. The holes are dug 20 cm deeper than the length of the roots.

At the bottom put a nourishing pillow from:

  • compost
  • ashes;
  • dolomite flour.

There is enough fertilizer for the plant for 3 weeks of active development and the formation of tops. Landing is best done in cloudy weather or in the evening. 2 hours before the event, the pits are abundantly irrigated with water (not less than a liter), and then they begin work. Gently put the bushes on the “pillow”, after which they crush it with earth, then water it again and raise the fallen seedlings.

To protect vegetables from return frosts, at night planting is covered with polyethylene. If you grow a culture under lutrasil for the first weeks, the dangerous insect, cruciferous flea, will not pester young plants.

After 3 days, the soil is mulched at the roots.


Healthy cabbage

Broccoli is useful, so gardeners love to plant it on their own plot. To get a rich harvest, the plant needs to create all the conditions.


The culture is very hygroscopic, so in the summer, watering is carried out every 2 days, and in the heat twice a day. For the normal development and formation of inflorescences, the soil is kept wet at a depth of 15 cm. The event is carried out in the evening, after the sun sets. Ultraviolet light harms young growth, so in the first weeks it is better to shade the bushes.

Before each irrigation, the hardened crust is carefully loosened, weeds are removed. Due to the increased humidity, growing broccoli from seedlings requires extreme caution. It is important to ensure proper aeration of the roots, otherwise the underground parts will rot. To facilitate care, it is advised to mulch the beds.

Top dressing

In order to get an abundant crop of healthy vegetables, it is necessary to provide the plant with regular fertilizers. Broccoli belongs to the "gluttonous" crops, so there are 3 mandatory procedures:

  • After rooting. After the seedlings have grown, it is watered with top dressing. To do this, a glass of organic matter is dissolved in a bucket of water, gently irrigated under the root, trying not to get on the stem and foliage.
  • In two weeks. A matchbox of nitrate is diluted in 10 liters of liquid. For each bush you will need at least 1 liter of solution.
  • Head formation. During this period, potassium-phosphorus preparations are needed that improve yield. 10 g of potassium sulfate, 45 g of superphosphate and 20 g of saltpeter are added to a bucket of water. All components are thoroughly mixed, and then poured under the plants.

After the central head is cut, the lateral processes stimulate. Without fertilizers, this is difficult to do, so 35 g of potassium, 15 g of nitrate and 20 g of superphosphate are diluted in 10 l of liquid. If you reduce the dosage by half, the solution can be used for sheet processing. This procedure brings plant nutrients faster.

Fertilizing is carried out after irrigation, otherwise the roots suffer. The crop will have to recover from stress, which will delay the harvest. It is not recommended to get involved in nitrogen and organic fertilizing, as they provoke the appearance of root rot.

Possible problems

Mistakes in agricultural technology occur not only among beginners, but also experienced farmers. It is important to determine the ailment or pest, and then proceed to immediate action. The less time you spend growing, the more problems.


The most common broccoli ailments are fungi. Pathogens develop in moist soil with thickened plantings, therefore, it is recommended not to save space when growing cabbage. Among the popular diseases, there are:

  • rot (white and gray);
  • mosaic;
  • alternariosis;
  • peronosporosis;
  • Fusarium wilt.

Fungi are afraid of copper-containing preparations, therefore, in the early stages of development, treatment with Bordeaux liquid is allowed. During the formation of inflorescences, it is advised not to stress the plants and choose a more gentle method. The Topaz fungicide effectively fights against ailments, but the best option is to pre-soak the seeds.


Broccoli annoy cruciferous fleas, aphids or slugs. In addition, a large number of flies prefers to feast on leaves.

If there are few insects, then it is easy to assemble them by hand or crush on tops. With a significant lesion, the plants are sprayed with a soap solution with the addition of ash. To quickly get rid of parasites, insecticides are treated (Actellik, Rovikurt, Foxima).

A mixture of tobacco dust, lime and charcoal is poured from snails and slugs along the beds. Sometimes slate sheets installed overnight help. Under them, mollusks hide from the heat of the day, the agrarian can only collect guests and destroy them.

To grow broccoli seedlings from seeds, you need to know all the requirements of the culture. A plentiful harvest will go to the farmer, who will be able to properly plant and care for broccoli seedlings at home.
