Other breeding methods of Iris flavescens

1. Bulb reproduction

The bulb reproduction of Iris is generally only one year old. After a year of growth, the nutrients of a bulb will be exhausted until death.

However, the bulbs produced by the development of the original bulb will still exist, and can continue to grow and develop, but also can produce beautiful yellow flowers.

2. Separate plant propagation

The ramet propagation of Iris flavescens can be carried out every 2-4 years, and usually in spring and autumn or after flowering. When dividing the rhizome, it is generally better to have 3-4 buds. If the ramet is too fine, it will affect the flowering of the second year.

If you want to grow yellow iris, you need to know how to reproduce it. The way to reproduce is not just to sow seeds. You can also learn about its other ways of reproduction, of course, the best time to plant should not be ignored, only in this way can we grow a healthy and luxuriant yellow iris.

Introduction to the breeding methods of Iris flavescens

Yellow iris like warm, moist and sunny environment, more cold-resistant, slightly shade-resistant, artificial planting is not difficult. We can spend the winter in the open field in the north, southwest and south of the Yangtze River. Yellow iris can be propagated by sowing and ramets.

Sexual reproduction is seed reproduction. Sow with picking and sowing, soak the seeds in warm water for about 12 hours before sowing, then remove the seeds that cannot germinate, then sow the soaked seeds on the culture soil that has been installed, then sprinkle a layer of sand or soil on it, add water 1-3cm, and cover it with glass to maintain the temperature and humidity in the basin, but leave a little gap to prevent excessive temperature from burning the seedlings. It can be germinated in about 20 days, and then separated and cultured after the seedlings come out.

Asexual reproduction is carried out before the Qingming Festival, first dig out the underground stem, clean it, remove the old root and stem, and then cut it into blocks with a sharp knife, it is best to disinfect it with Dysena. when cutting, pay attention to not harming the plant buds. It is appropriate to keep 4 buds in each piece.

Propagation method of Iris flavescens: ramet, sowing and bulb

Yellow iris is a kind of perennial herbaceous plant, the flower is yellow, it is very beautiful when it blooms, the flower contains 2 flowers, the flowering period is from May to June, we can see the figure of yellow iris in hillside grass and forest edge grassland, it has high horticultural value, the following is to learn about the breeding method of yellow iris.

Propagation method of Yellow Flower Iris 1. Ramet of Yellow Flower Iris

Ramet propagation is generally carried out every 2 to 4 years, in spring, autumn or after anthesis. Iris splits after anthesis (to avoid the rainy season). The flower buds can differentiate well before winter and blossom the following year. It is better to have 3 to 4 buds when dividing the rhizome. If the ramet is too small, it will affect the flowering of the following year. In ramet propagation, the upper leaves of the plant should be cut off and left about 20 cm for planting. Most varieties of Iris are suitable for shallow planting. The planting spacing varies according to the species, the strong species is 50 × 50 cm, and the general variety is about 20 × 20 cm.

A, applying sufficient basal fertilizer, the soil should keep high humidity during the growing period, especially at the flowering stage, the roots should grow in water, and the water depth 5~7cm is suitable.

B. Soil pH planting should be below 6.5. otherwise, the plant will grow slowly and yellowing may occur.

C. fertilize for 3 to 4 times during the growing period, and pay attention to the removal of weeds and withered yellow leaves. Summer high temperature, should often spray water to the leaf surface, increase air humidity, make seedling strong leaf green.

2. Sowing seeds of Iris flavescens

If the seed is used for propagation, it should be carried out immediately after the seed is mature, so that the seed is easy to germinate and can blossom in 2 to 3 years. Pot sowing from March to April, the optimum temperature for germination was 18-21 ℃, germinated 15-20 days after sowing, and transplanted when the seedling was high 5~6cm.

3. Iris flavescens bulb

After a year of planting and flowering, a seed ball will run out of nutrients and produce new roots, and there will be many bulbs around the new bulb, which can develop into a flowering ball after one or two years of planting. The world flower planting experts carry out tissue culture of axillary buds, bulbs, stem plates, flower stems and other different organs of Iris bulb to make it grow new bulbs, which provides a new way to accelerate propagation and cultivate disease-free strong mother balls.
