Cabbage is propagated using seeds that remain viable for four years. Cultivation is carried out by seedling method and planting seeds in open ground.

Seedling cultivation

Sowing seeds for seedlings is carried out from March 15 to April 10. Before sowing, the seeds are treated with a 1% solution of potassium permanganate to prevent fungal diseases and soaked for three hours in the growth stimulator “Heteroauxin” to increase germination.

Seeds are recommended to be sown in separate cups. This will facilitate the transplantation of seedlings to a permanent place of growth and protect against damage to the roots.

Prepare the soil for sowing seeds by mixing the following ingredients:

  • sod land;
  • humus:
  • peat ;
  • sand.

These components are mixed in a ratio of 2:1:1:1 Before use, it is recommended to keep the soil mixture in a microwave oven for 20 minutes to destroy pathogenic microbes and larvae of harmful insects.

The prepared soil is poured into cups with a hole made in the bottom to remove excess moisture, and one grain is sown in each, deepening it into the ground by 10 mm.

Cups with seeds are covered with cling film, which is not removed until the seeds germinate. Place containers in a well-lit room with a temperature of + 20-22 degrees. The first shoots will appear on the fifth day. After the appearance of sprouts, polyethylene is removed from the cups and the temperature is lowered for three days to +12 degrees. In the future, seedlings are grown at a temperature of +18 degrees.

For good growth and full development, you need to take care of bright, but diffused lighting. With a lack of light, the seedlings will stretch, and subsequently the thin stem will not withstand the load.

Care

Cabbage seedlings love moist soil . Watering should not be frequent, but plentiful. Cabbage responds well to spraying with a spray bottle with warm settled water. There should not be much moisture, otherwise the plant will get sick with a black leg.

To improve growth, seedlings need top dressing. The first dressing is applied when the seedlings have two true leaves. To do this, two grams of nitroammophoska are diluted in one liter of water. Seedlings are watered with the solution. The second top dressing is carried out 14 days before transplanting seedlings to a permanent place of growth.

Transplantation in open ground

In early May, if the seedlings have three true leaves, it is planted in a flower bed . Two weeks before transplanting, the seedlings begin to harden, taking out for a short time in fresh air. Gradually, the time the seedlings stay on the street is increased.

For good growth of seedlings, it is necessary to choose the right site for further growth. When choosing a site, the following nuances should be considered:

  1. The place where seedlings will grow in the future should not have an accumulation of moisture.
  2. The site should be well lit, as with a lack of lighting, the brightness of the leaves can not be expected.

Planted plants according to the scheme 40X40. Transplant in cloudy rainy weather, or in the evening, so that the seedlings have time to adapt. The seedlings are buried in the ground to the cotyledon leaves, the soil around the stem is compacted so that voids do not form around the roots.

After planting cabbage in a permanent place of growth, it is necessary to immediately introduce nitrogen-containing top dressings and organic matter. It is not recommended to fertilize young seedlings with manure, as this can cause the plant to lose its decorative color.

Outdoor seedling care

Caring for ornamental cabbage includes a number of the following activities:

  1. Abundant watering is carried out every four days. Every day in the evening, it is necessary to spray the leaves with a spray bottle.
  2. The soil after watering must be loosened to prevent stagnation of moisture in the soil and the formation of a crust that prevents the penetration of oxygen to the roots. This will help prevent root rot.
  3. Regular removal of weeds is essential. To reduce the number of weeds, the soil around the seedlings should be mulched with sawdust.
  4. Twice during the summer period it is necessary to apply complex mineral fertilizers under the root and perform one spraying of the foliage.
  5. To prevent the attack of harmful insects, cabbage is recommended to be sprayed with insecticides for prevention.

Sowing seeds in open ground

In open ground, seeds are sown from May 15 to June 15. The soil is prepared in the fall, introducing when digging for 1 sq. meter the following fertilizers:

  • compost – 3.5 kg;
  • ammonium sulfate – 20 grams;
  • superphosphate – 42 grams;
  • potassium chloride – 15 grams.

To normalize the level of acidity in the soil, it is recommended to add lime.

Sowing seeds is carried out in early April. Seeds are sown to a depth of 15 mm with an interval of 5×5 cm. The area with seedlings is covered with polyethylene to create greenhouse conditions. After the appearance of the first sprouts, the polyethylene is removed. If the seedlings have four true leaves, it is necessary to thin out, leaving the strongest, well-developed specimens. Less developed seedlings are transplanted to another place and grow. The distance between the remaining seedlings should be at least 35 cm.

Seed collection

Seed collection

Ornamental cabbage reproduces by seed. To get seeds, you need to dig a bush with a clod of earth in the fall, cut off the lower leaves, leaving only the top and dig it in the sand. Moisten the sand, and place containers with rosettes in a dry room with good ventilation. So that the roots do not dry out, the sand must be periodically moistened.

In the spring, as soon as good weather sets in, the cabbage is planted in open ground. For good pollination, you need to plant several bushes nearby.

The flowering period begins in June. As soon as the inflorescences fade, seed pods appear in their place. So that the birds do not peck the seeds, the pods must be covered with material. When the pods begin to dry out and change color, they should be plucked, bundled, and hung from the ceiling in a dry, well-ventilated area. Spread newspaper under the bunches of pods. You need to wait two weeks for the final drying. Then split the pods and collect the seeds.

Difficulties in growing ornamental cabbage
