The Best sowing time of Iris flavescens

The best planting method of Iris chinensis is autumn sowing and autumn harvesting. The seeds should be soaked in warm water for half a day before sowing, so that the seeds will germinate more easily and grow seedlings in the spring of the next year.

In addition, seeds can be stored in sand until the following spring before sowing, this period of sowing yellow iris but relatively easy to survive.

Only know yellow iris seed reproduction is not very able to satisfy your desire for knowledge? Here are a few more ways to share the breeding of yellow iris!

Iris flower propagation method: Iris flower plant, seed, seed ball

Yellow iris is a perennial herb, flowers are yellow, flowers bloom very beautiful, flowers contain 2 flowers, flowering 5-6 months, we usually in the hillside grass, forest edge grass can see the figure of yellow iris, there is a high horticultural value, the following is to understand about the reproduction method of yellow iris.

Iris flower propagation method 1, Iris flower ramets

Ramets are generally propagated every 2 to 4 years, in spring and autumn or after flowering. Iris after flowering for plant division (to avoid the rainy season), before the arrival of winter flower buds can be differentiated sufficiently, the next year can flower. When splitting the rhizome, 3 to 4 buds are preferred. If the ramets are too thin, they will affect the flowering of the following year. When carrying out ramet propagation, the upper leaves of the plant should be cut off and left about 20 cm for planting. Most species of iris should be planted shallow. The planting spacing varies according to the species, with strong species being 50×50 cm and general varieties being about 20×20 cm.

A, apply enough base fertilizer, keep high humidity in the soil during the growth period, especially during flowering, the roots need to grow in water, and the water depth is 5~7cm.

b. Soil pH is best below 6.5, otherwise the plant grows slowly and yellowing may occur.

c. Fertilize 3~4 times during the growth period, and pay attention to removing weeds and withered leaves. Summer high temperature, should often spray water to foliage, increase air humidity, make seedlings strong leaves green.

2. Sowing of yellow iris

If seed propagation is used, it should be carried out immediately after seed maturity, so that seeds can germinate easily and flower in 2 to 3 years. Sowing in pots in March and April, germination temperature 18~21℃, germination 15~20 days after sowing, transplanting when seedling height 5~ 6 cm.

3, yellow iris seed ball

A seed ball will be depleted of nutrients after one year of planting and flowering, and new roots will be produced. There will be many seed balls around the new ball. After one to two years of planting, the seed balls can develop into flowering balls. The world flower planting expert carries on the tissue culture to the bulbous iris axillary bud, the bulb, the stem disk, the flower stem and so on different organ, causes it to grow the new corm, this provides the new method for the acceleration reproduction and the cultivation disease-free healthy mother ball.

Other ways of reproduction of yellow iris: one, seed ball reproduction

The seed ball propagation of Iris chinensis is generally only annual. After a year of growth, the nutrients will be exhausted after flowering until death.

But the seed ball produced by the seed ball development will still exist, and can continue to grow and develop, but also can produce beautiful yellow flowers.

II. Plant division propagation

The ramet propagation of Iris chinensis is generally carried out once every 2-4 years, and is generally carried out in spring and autumn or after flowering. When dividing rhizomes, it is generally better to have 3-4 buds. If the ramets are too thin, they will affect the flowering of the next year.

If you want to plant yellow iris, you first need to understand its reproductive mode. The reproductive mode of yellow iris is not only sowing! You can also learn about its other reproductive methods, of course, the best time to plant must not be ignored, only in this way can grow healthy and lush yellow iris.
