Curly kale sowing propagation time

Curly kale sowing propagation is usually done in summer, and early seeding can lead to yellowing of old leaves in the later stages of growth, making management more difficult and extending the management period. If the sowing propagation time is too late, it is easy to cause the leaf bush crown diameter can not reach the required specifications at the time of nursery.

Sowing propagation method of Curly kale  

The sowing propagation method of Curly kale can be done in the open. Generally used as a point or bedplate seedling these two methods. In order to drain the water in time during the heavy rainfall months of July and August, the seedbeds need to be raised to a height of about 20 cm above the ground.

Before sowing propagation method of Curly kale, it is necessary to set up the arch frame and prepare the plastic film. Once the heavy rain can be covered in time, so as to avoid reducing the emergence rate due to rain erosion. The seedling substrate can be 40% peat and 60% perlite, and carbofuran can be used to disinfect the soil and kill insects to reduce the occurrence of pests and diseases. Before sowing sowing propagation method of Curly kale, it is necessary to spray the soil with water first, and then directly sow seeds on it. The depth of coverage is appropriate to just cover no seeds. After sowing propagation, it is not necessary to water again. At a temperature of 15-20℃, seedlings can emerge in about a week.

Curly Kale Blue propagation care

After Curly Kale propagation, the ransplantation is usually carried out when 4-5 true leaves of seedlings grow, and transplanting is carried out in mid to late November, and 3-5 transplants are generally required. Curly Kale can be transplanted bare-root. When planting, strip off the outer old leaves, which not only accentuate the color of the heart leaves, but also reduce water consumption, and promote the plant to restore growth as soon as possible.

After Curly Kale propagation, there is a strong demand for nitrogen fertilizer in the early growth stage, so top dressing is required to ensure adequate nutrient supply. When planting, prepare plenty of base fertilizer. Topdressing can be started about a week after seedling transplantation. In autumn, the climate turns cool, the growth speed accelerates, and the nutrient absorption increases. At this time, we should also pay attention to providing adequate water and fertilizer. Stop applying nitrogen when the plants start to change color. The outer leaves showed yellowness and shedding after insufficient fertilizer.
