Who can talk about marigold?

Wanshouxiang is actually making incense: scientific name: Jiexiang, also known as Jiehua and Huang Ruixiang.

Originated in Shaanxi, Henan, the Yangtze River basin and even the southwest. The branches of deciduous shrubs are tri-branched, soft and jointed. Flowers are yellow and fragrant; In early spring, the leaves open first and there are all kinds of red flowers. Hardy. I like a semi-cloudy environment with good drainage, because fleshy roots avoid waterlogging.

Propagation can be divided into plants or cuttings in early spring and early summer. It is a common flowering shrub in gardens, and can also be potted and bent. Xiang Jie belongs to Daphne, and Xiang Jie is a deciduous shrub. Originally from China, it is distributed in the Yangtze River valley and Henan, Shaanxi and Southwest China. It is a common early spring flower in China gardens, with a height of 1? 2 meters, the small core is reddish brown, thick and soft, and can be knotted continuously, hence the name "knot flowers and trees". Usually trigeminal, yellow filiform villous. Leaves alternate, usually clustered at the top of branches, oblong, 6? 20 cm, entire, leaving prominent leaf scars after defoliation in late autumn. The flowers are yellow and fragrant, and 40-50 clusters form a pseudo-head, which is born at or near the top of the branch, drooping, and the total stalk is thick and short. Perianth is cylindrical, with four teeth at the apex and petal-shaped. Drupe ovoid, like a honeycomb. After the leaves fall in late autumn, the buds hang down from the branches, and the leaves open first in the next spring. Xiang Jie is a warm temperate tree species, which likes semi-shade, but also endures sunlight. Like warm climate, poor cold tolerance, so it is cultivated in the northern greenhouse. Fertile loam with good drainage grows better and avoids saline-alkali land. Fleshy roots, not resistant to water and humidity, poor drainage, easy to rot roots. Xiang Jie is propagated by ramets and cuttings. The ability of budding and tillering is strong, which is beneficial to the propagation of ramets, and buds and tillers are clustered around the mother plant. Plant division should be carried out before germination in spring. This method is simple and convenient. To choose a vigorous mother plant, just cut off the roots connected with the sprouting branches, pay attention to the newly separated plants with roots and plant them directly in the nursery. Cutting is usually carried out in February-March. Select the middle and lower parts of robust annual branches and cut them into 10? 1.5 cm skewer is inserted into half of the soil, compacted, fully watered and kept wet, but not too wet, shady or semi-shady. They can take root and sprout in the rainy season and survive easily. They can grow to be 50 years old that year. 70 centimeters tall. Cutting period can also be carried out in June-July. The cultivation of incense is very easy and does not require special management. Whenever the old branches are aging, they should be pruned and updated in time. Transplantation takes place in winter and spring. Generally, bare roots can be transplanted, and clumps of seedlings should be brought with mud balls.
