How to grow blue flax planting methods and matters needing attention

Blue flax is more common in life, its flowers are small and delicate, petals are blue around the white core, beautiful and generous, especially suitable for ornamental flowers and plants in flower beds. Although blue flax is delicate and beautiful, it is not delicate. It is a very good farmed flower. Let's learn the planting method of blue flax with Xiaobian.

How to grow blue flax

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.

Planting methods and matters needing attention of Blue Flax

1. Water management

Sufficient water is needed during germination and seedling stage, and water is sprayed once or twice a day to keep the soil layer moist. With the growth of seedlings, the times of watering gradually decreased. Pay attention to replenishing water when the climate is dry, and do a good job of winter irrigation before winter, which is conducive to overwintering and turning green.

2. Fertilization management

If the sowing plot is very barren and needs proper fertilization, it is generally combined with soil improvement before sowing, and it is best to use organic fertilizer or low-nitrogen compound fertilizer. Pay attention to avoid excessive fertilization, otherwise Bay U will be conducive to the growth of weeds, resulting in the excessive growth of flowers and flowers, reducing flowering.

3. Weed control, seedling intercropping and seedling transfer

Weed control is the most important problem in seedling and later maintenance. If there are many weeds in the sowing area, it is suggested to control the weeds in two steps. the first is watering before sowing to promote the germination of weeds and spraying herbicides or eradicating them after germination. The second is to remove weeds after flower seed germination so as not to spread, and the growing period can be managed extensively. When the growth of seedlings is dense, it is necessary to alternate seedlings properly, which is beneficial to the growth of seedlings. At the same time, the seedlings are replanted to the scarcity place, so as to maintain a better overall landscape effect.

4. Pruning

In order to make the blue flax plant type plump, the coring treatment can be carried out during the growth process. Generally, the top tip is removed when the seedling height is 6 ~ 10 cm, which promotes the formation of branches. 3 ~ 5 weeks after the first heart extraction, the lateral branches can be removed for the second time. Coring can not only adjust the plant type, but also increase the number of flowering. If you want to bloom for the second time, you can leave the rhizome 15 ~ 20 cm after flowering in May ~ June, cut off its upper part and promote new branches, which can blossom again around October.

How to cut Blue Flax

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.

When does blue flax blossom

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.

As mentioned above, blue flax is easy to breed, so many people grow blue flax, and blue flax is not only beautiful and exquisite, but also edible, especially delicious, fresh and delicious leaves, high nutritional value.
