The method of split-plant Propagation of Brazilian Iris

Brazilian iris can be propagated by ramet and sowing methods, but because Brazilian iris is prone to variation in sowing and reproduction, it is generally used to cultivate new varieties, so Brazilian iris is mainly propagated by individual plants.

Iris sibirica

It can be carried out when the rhizome is elongated, once every 2-4 years, after flowering in spring and autumn. After anthesis, the flower bud can differentiate in autumn, and the flower bud is better in the next year. When dividing the rhizome, it is better to have 2-3 buds for each piece, with at least one bud. Sowing should be carried out immediately after the seed is mature and blossom 2 ~ 3 years after sowing.

Brazilian iris is often propagated by bulbs, and the bulbs can be harvested every 2 ~ 3 years. After harvest, put it in a ventilated, dry and cold place. The bulbs and fibrous roots attached to it should not be separated or removed, otherwise the wound will rot and should not be separated until it is planted in autumn. New corms can also be cultured by tissue culture with different organs such as axillary buds, axillary plates, chassis, flower stems and so on.

Split-plant method and sowing method

Propagation of Brazilian Iris by split-plant method

Plant division is the most commonly used method for the reproduction of Iris brasiliensis.

First of all, it is necessary to select healthy ramets, dig the rooted flower stem seedlings, prepare containers and loose, nutritious pot soil, plant the flower stem seedlings, and fertilize them after planting. The fertilization period is about 3 months. Brazilian iris should remove withered leaves and yellow leaves in time in order to protect the plant growth environment, which is also conducive to ventilation and promote the healthy growth of plants.

Propagation of Brazilian Iris by sowing method

The first thing the sowing method should do is to collect the seeds of Iris brasiliensis, prepare the planting containers and nutritious substrates, dig a few small holes in the substrate, spread the seeds evenly in the dug holes, cover them with a layer of loose soil, then water them thoroughly, apply a certain amount of fertilizer and cover them with a layer of fresh-keeping film, preferably covering the top of the plant with a shade net. Ensure a good growth environment for the plant.

How to raise Iris brasiliensis

Brazilian iris is native to Mexico, alias Iris orchid and jade butterfly. Brazilian iris leaves are bright and green, with a strong sense of lines, and the flowers have a short life span but bloom in turn, so the ornamental effect is good. How do you raise Brazilian irises? Next, let's learn how to cultivate Brazilian iris.

First, how to raise Brazilian iris

Brazilian iris is easy to plant and has a strong tolerance to the environment. It can grow well in all-day light, half-day light and bright scattered light, but if you want the leaves to grow verdant and flourish, it is better to grow in a half-day or shaded environment. Therefore, the wall, under the shade, or the bright interior are all ideal places for cultivation. Brazilian iris likes to keep the soil moist, and it should be careful not to lack water in summer, otherwise the leaf tip will dry up and affect the ornamental value. When planted in Taiwan, growth stops only when it is low in winter, but it grows vigorously in the rest of the season and always stays dark green.

2. Culture methods of Brazilian Iris

The soil quality of Brazilian iris cultivation is fertile loam or humic soil, and the drainage is good. All-day sunshine and half-day sunshine can grow, but the sunshine in semi-shade is about 6070%, and the leaf color is better. Fertilizer can be applied with organic fertilizers such as soybean cake, oil meal or three elements, once every 1 to 2 months. Like dampness, culture soil should always keep humidity, drought and poor fertility. Sex likes high temperature and humidity, the suitable temperature is about 20-28 degrees Celsius C, warm and sheltered from the wind in winter, cold spell below 10 degrees C needs to prevent cold injury, dry air will lead to scorch of leaf tips. The tufted plants that have been cultivated for many years are overcrowded and should be planted in separate plants.

Ramets only need to dig the rooting flower stem seedlings and plant them separately. Fertilization can be done from spring to autumn with Huabao No. 2, 1000 times liquid, once every two weeks, and apply long-acting fertilizer to the basin, such as Haokangduo No. 1, once every three months. Need to regularly remove yellow leaves, old leaves, in order to maintain a clean environment and conducive to plant ventilation, if the plant growth is too dense, need to plant sparsely.

The above is the introduction of Brazilian iris culture methods, like Brazilian iris friends can learn, hope to help you breed Brazilian iris.
