Garden uses

The crown of the fragrant tree is spherical and the branches and leaves are beautiful. It is suitable for planting in the garden or as a potted plant for viewing. The whole plant is used for medicinal purposes; the bark can be used for fiber, which is used to make paper; the branches are soft and can be used for basket weaving.

The knotted incense has an elegant posture and its soft branches can be tied into knots. It is very attractive and suitable for planting in front of the garden, roadside, waterside, between rocks and in wall corners.

In the north, there are many potted plants for viewing. The branches are soft, can be bent and knotted, and often formed into various shapes.

Propagation and cultivation

Jiexiang

Ziexiang is propagated by division and cutting methods.

The tiller sprouting ability of Yuxiang is very strong.

The sprouting tillers form clusters around the mother plant.

This is a favorable condition for division propagation.

Dividing should be carried out before germination in spring. The method is simple. Select a strong and healthy mother plant. Just cut off the roots where the tillering branches are connected to the mother plant.

Pay attention to the new divisions. All plants must have roots and can be planted directly in the nursery.

Cutting is usually carried out from

2

to

3

, and strong annual branches should be selected. Cut the middle and lower parts into skewers of

10

—

15

cm,

Insert half of the plant into the soil, press it firmly, water it thoroughly, and keep it moist, but it should not be too wet, shaded or semi-shaded, or moldy.

It can take root and survive in the rainy season. It is very easy and can grow to

50

—

70

cm tall in a year. The cutting period can also be carried out from

6

to

7

months.

Cultivation of knotweed is very easy and requires no special management. Whenever the old branches become senile, they should be pruned and renewed in time. Transplantation is carried out in winter and spring. Generally, bare roots can be transplanted, and large seedlings in clumps should be brought with mud balls. The branches are sparse, thick and soft, brown-red, and not easy to break.

Because the branches are soft and can be knotted continuously, it is named Jiexiang. Branches once a year, each branch producing

flowers are gathered into drooping false flower heads. After flowering, there are leaves, which are alternate with entire margins, oblong, and clustered at the ends of the branches. Drupe is oval. The fragrant nature likes a warm climate and is tolerant of semi-shade and sunlight, but not cold. The roots are fleshy and

are afraid of water and moisture. They grow well in fertile and well-drained soil, and tillers tend to grow on the root neck.

Propagation includes ramification,

cutting, layering and other methods.

Division

In early spring, before germination, take the thick seedlings and cut them off. The roots connected to the mother plant can survive if they are planted in the ground again

and can be transplanted the following year.

Layering

Choose thick tiller branches,

peel the side pressed into the soil in a semi-circular shape,

deep into the xylem ,

Buried in the soil,

The branches are slightly exposed,

Keep them moist. The mother branches can be cut off and cultivated separately the following year. Transplantation should be carried out in winter and spring. Can be transplanted with bare roots. Keep the soil moist during cultivation. Drought can easily cause leaf fall and affect flowering. The old branches of adult knotweed should be pruned to maintain the fullness of the tree.

Function

It has fragrant, soft branches and long leaves, elegant posture, many flowers in clusters, and overflowing with fragrance. It is suitable for solitary planting, row planting, and cluster planting in front of the courtyard, along the road, in the corner of the wall, in the lawn, or dotted next to rockery rocks, or as a potted plant. In addition, knotweed has an insect repellent effect, and its roots, stems, and flowers can also be used medicinally, with the effects of relaxing muscles and activating blood circulation, reducing swelling and relieving pain.

Cultivation Points

The knotweed grows robustly,

has strong adaptability,

has few pests and diseases,

needs Special management can also bloom.

To make the flowers more abundant and fragrant, you must pay attention to:

Sandy loam soil is best cultivated with fragrant fleshy roots.

No matter the location It is better to plant potted plants in well-drained and fertile sandy loam soil.

Avoid

saline-alkali soil. For potted plants, a layer of broken bricks must be placed at the bottom of the pot to facilitate ventilation and drainage. Transplanting or repotting should be done after the flowers fade. Before the new leaves

open, remove the soil balls to avoid affecting next year's flowering. Watering and fertilizing should be moderate. It is advisable to water regularly during the growing season to keep it slightly moist.

Standing in water can easily cause root rot, and excessive dryness can easily lead to leaf fall, which will lead to fewer flowers the following spring. Apply a fertilizer based on nitrogen fertilizer once after flowering to promote the growth of branches and leaves. Apply a compound fertilizer based on phosphorus and potassium fertilizer once in autumn to promote the differentiation of flower buds. No fertilizer is applied during the rest of the time.

It likes semi-humidity and sun protection. It likes semi-shade. Plant or place it against the north wall and face south to avoid the scorching sun in midsummer.

It can bask in the sun in winter. For the best. Potted plants should be placed in a place with better sunshine from autumn to spring, and in a semi-shaded place in summer. Over-exposed leaves will easily turn yellow and there will be few flowers; over-exposed shade will cause the flowers to have a weak fragrance.

It is a temperate tree species that likes warmth and is cold-resistant. It likes a warm climate, but it can also withstand freezing temperatures within - 20℃

south of Beijing.

Overwintering outdoors,

Only in winter -

10

℃ to -

20

In places with ℃,

the flowering period should be postponed to

3

month to

4

In places where the temperature is lower than -

20

℃

in winter, it is only suitable to plant in pots. In winter, place indoors A south-facing windowsill will do.

It is easy to propagate by cuttings from ramets. The fragrant wood is loose and will age after about 10 years of cultivation. You should pay attention to propagating new plants to replace them.

The cuttings from the ramets are easy to survive.

The ramets can be combined with potting and filling with soil.

The daughter plants that have sprouted from the roots of the mother plant can be cut off and planted again

. Cuttings can be made when the ground temperature is

15

℃ or above. Select the middle and lower parts of strong annual branches and cut them into

, water and place in a shaded place, spray water frequently to keep warm.

It can take root in about 50 days

and can be planted on the following spring equinox.

For home propagation, it is better to use divisions.

The flowers will be visible in the next spring.

For flower farms, it is best to use cuttings.

Reproduction coefficient Large,

but flowers will not appear until the third year.

Disease prevention and control

. Vitiligo

High temperature, high humidity and poor ventilation are likely to cause this disease.

Prevention and treatment methods:

①Choose healthy and disease-free plants.

② Remove diseased residues or other organic residues and weeds from the soil, which is not conducive to the development and growth of sclerotia.

③ Pay attention to drainage and apply more organic fertilizer to promote the healthy growth of fungus and wood and improve disease resistance.
