What the editor wants to bring to you in this article is how to cultivate and maintain the naked root eight Immortals with a high survival rate. Let's take a look at it.

1. Cut off the dead roots, rotten roots and dried roots. It is best to cut it into a bevel so that the root can fully absorb nutrients. Then put it into the soil and water it well and put it in a cool place.

2. Planting in the open field should be planted in shady places where the sun does not shine directly, such as under the big tree, on the side and behind the house. It is suitable to be planted in clusters at the edge of the grass path, and it should be matched with other flowers and trees to form the flower diameter.

Planting methods of bare-root eight Immortals

4. Baxian flowers like fertile, humus-rich, well-drained slightly acidic to slightly alkaline soil. In open field cultivation, mature organic fertilizer was applied before sprouting in early spring to ensure exuberant growth and breeding of flower buds. Pot planting should be carried out in the north, and the potted soil should have enough fertility. Therefore, the basin soil is generally changed every 1-2 years to supplement fertility, and dilute liquid fertilizer is irrigated once a week during the growth period.

5. under the condition of sufficient fertilizer and water, the flowers grow fast and the flowers are big and colorful. If the color of the sterile flower is yellow after anthesis, the flower head should be cut off in time, and the branches should be cut short. Generally, only the basic two sections are left to promote the germination of new branches. when the new branches grow to more than 10 cm, they will be coring, keeping 2-3 nodes, and at the same time removing weak branches, so that nutrients can be concentrated on strong branches to ensure their growth and fullness, so as to ensure large and plump flowering in the second year.

6. Prune before winter, then move into indoor management, and control watering, stop fertilization in preparation for overwintering. If the indoor temperature can be kept above 15 ℃ and a certain humidity can be maintained, it can be placed in front of the window with sufficient light to continue to cultivate, strengthen the management of fertilizer and water, not only keep leaves from falling, but also continue to blossom, and watch leaves and flowers in winter.

1. Reproduction: the eight Immortals can easily survive and can be propagated by cutting or dividing plants. Cuttings should be carried out in spring and summer, with 1-year-old branches, cut into 10-15 cm long segments as cuttings, cut into sand beds, rooting for about 20 days, and then transplanted and cultured in a basin. The split-plant propagation of taxis should be carried out before the germination of the plant in early spring, and it can be divided into several plants according to the root potential of the mother plant, cut off the clever root and overgrown root, transplant it in a basin prepared in advance for cultivation and management, and prune at the same time.

2, fertilization and watering: Baxian flowers like fertilizer, generally every 15 days need to apply mature thin cake fertilizer water, the application of cake fertilizer should avoid summer days, so as not to cause diseases and insect pests and damage to the root system. In order to keep the basin soil acidic, 100 grams of ferrous sulfate can be added to every 50 kg of liquid fertilizer to irrigate; at the same time, frequent watering of alum fertilizer can make the plant branches and leaves green, and the application of 1-2 potassium dihydrogen phosphate solution during the bud period can make the flowers bright.

Baxian flower has hypertrophic leaves, luxuriant branches and leaves, and needs more water. In spring, summer and autumn, it is necessary to irrigate enough water to keep the basin soil moist. Especially in hot summer, due to the large amount of evaporation, in addition to watering enough water, but also spray water to the leaf surface once a day or every other day. Eight Immortals for fleshy roots, too much water is easy to rot roots, so watering should not be too much, after the rain to pour out the stagnant water in the basin. After September, the weather is getting cooler, it is necessary to gradually reduce the amount of water to make the branches grow strong, in order to facilitate winter dormancy.

Frosts Descent moved into the room and kept the room temperature at about 5 ℃ to promote its dormancy. The leaves should be removed before the beginning of winter to avoid rotten leaves. Starting from mid-December, he moved to Xiangyang one after another, and Grain Rain left the room the following year.

3, turn the pot to change the soil: potted eight immortal flowers, generally turn the pot to change the soil once a year. It is generally appropriate to turn the basin and change soil in spring. The culture soil was prepared with rotten leaf soil, garden soil and sandy soil according to 4:4:2, and then an appropriate amount of rotten cake fertilizer was added as base fertilizer. When changing pots, it is necessary to prune the roots of the plant, cutting off rotten roots, rotten roots and overlong roots. After the plant is moved into the new pot, the soil should be compacted, then watered thoroughly, placed in a shaded place for about 10 days, and then moved outside for normal management.

4. Pruning and shaping: in order to make the potted eight Immortals beautiful crown, correct plant shape, and more flowering, it is necessary to prune the plant. As the flower head of the eight Immortals is too large, a bracket should be set up in time, which can not only keep the flower plant erect, but also make the plant appear plump.

The eight Immortals are vigorous in growth and resistant to pruning.

The eight Immortals usually bloom on biennial strong branches. after flowering, the old branches should be cut short and 2-3 buds should be retained to restrict the plant from growing too high and promote the growth of new shoots to facilitate flowering in the coming year. Cut off the top of the new shoots after autumn to stop the branches from growing so as to survive the winter. In early spring and March every year, the disease and insect branches and weak branches should be cut off from the base, only the strong branches should be retained, and the strong branches should be cut short (2-3 buds per branch) to promote new branches and make them bloom and flourish.

After the above pruning and shaping, the tree is compact, full, symmetrical, with many flowers, big flowers and colorful flowers.
