How to plant blue flax seeds of Rosa subclass? How to cuttage? When will it blossom?

Lanhua Yaxi has sufficient light and strong cold tolerance. Because of its strong adaptability, it can be used as ornamental food, so how to grow blue flax seeds? How to cuttage? When will it blossom? It is understood that blue flax is a plant that likes light, its adaptability is relatively strong, and its cold tolerance is not weak. The requirement for the environment is to feel cool, and the soil is generally fertile and well-drained.

First, how to plant blue flax seeds?

1. Planting method

The seeds of blue flax are washed and soaked, then put into fine sand and mixed on the ground to dry, which can make the seeds grow better in the soil. After the seeds are dried, they are sown in the soil where the seedlings are cultivated, and the seeds are covered with fine sand and wetted. After the seeds germinate, the seedlings are moved to the normal basin soil for growth and development, and the stunted seedlings can be pulled out in this process.

During the planting period, weeds usually grow together, so pay attention to the growth of the grass, pull it out regularly, and fertilize a small amount of fertilizer many times.

2. Management methods

The growth of blue flax is inseparable from water and fertilizer. In the early stage, it is necessary to ensure the nutrients needed for growth, fertilizing and watering regularly. When the seedlings grow up, reduce the amount of fertilizer application, and the irrigation of water should still be maintained in an appropriate amount. The growing blue flax needs to remove the flower heart manually, so that it can branch and grow better, and the branched blue flax also needs to be coring. After two coring, the blue flax can blossom normally. At this time, the blue flax will appear particularly luxuriant.

Second, how to cut it?

1. The time of cutting

This kind of flower can be cut, and it is best to choose a period of good growth, but before flowering. Because during this period of time, no matter the temperature or the surrounding environment, it is more suitable for plant growth, and it is easier to survive after successful operation. It can grow well without too much control over its surrounding environment.

2. The process of cutting

The selected branches should not be too young, and if they are too young, they cannot be guaranteed to survive, because their ability to absorb nutrients is not enough to survive on their own. But you can't choose plants that are already sick, so there's no need to explain. You can't let them be sick from the beginning. But be sure to keep the temperature in the cutting process, because you don't like rooting if it's lower than 18 ℃. But not too high, more than 25 ℃ can easily lead to cut mouth infection with bacteria, may also cause cut mouth rot. So this noodle must be under control.

Before the start, it is best to carry out disinfection, and then apply the rooting reagent, and after the lower part of the plant is dried, you can cut it. Watering should be carried out immediately after the cuttage is finished, so that the substrate will combine better with the cuttings and ensure the moisture needed for the early survival of the plant.

3. Maintenance after cuttage

In the initial period of time, shading should be carried out, because the plant may not adapt to the surrounding environment. When the plant growth is relatively stable, the shading device can be removed slowly and enter the normal maintenance stage. In addition to this method, of course, you can also choose to sow seeds, but relatively speaking, this method is simpler and faster.

When will it blossom?

1. The flowering time of blue flax

Blue flax blossoms usually in summer. Its florescence is between May and July, and it is a biennial plant. When blue flax blossoms, the flowers bloom one after another, generally, each flower does not last for a long time, but the whole flower blossoms for a long time.

Blue flax flowers are very delicate, usually terminal or axillary, with five petals and the color is blue or light blue.

2. Florescence control of blue flax.

Blue flax is a more exuberant flowering, it has a large number of flowers, breeding needs appropriate fertilization, but not excessive, excessive fertilization will lead to its overgrowth, is the reduction of flowering.

In order to make it blossom better, how long the flower branches are, and the plant is plump, it is very important to pick the heart in time.

Generally, when the small seedlings of blue flax grow to 6--10cm, it is necessary to pick the heart once, so that how long the branches can be branched, wait until about 5 weeks after the first coring, and then the second coring can be carried out. At this time, the side branches of blue flax are coring, which can promote them to branch again.

If blue flax is to blossom again after blooming, it is necessary to cut off the upper part of the plant and retain 15--20cm in the lower part, so that it can grow new branches and blossom again in October.
