An in-depth explanation of the pruning methods and related knowledge about the cultivation and precautions of Zhusuan for concerned netizens. Let's follow the editor to take a look!
Zhusuan belongs to the Chloranthaceae family as an evergreen small shrub, with branched stems and prominent nodes. The leaves are opposite, contain oil cells, are waxy, dark green, and glossy. The flowers are small, terminal, paniculate, greenish-white, rice-like in shape, with a strong fragrance, and often used for roasting tea. Zhusuan tea is a high-grade fragrant tea. The blooming period is from June to July, and it can be slightly extended. Zhusuan prefers shade and grows well in dry and cool places. It is propagated by division, layering, or cutting, with layering commonly used in Wuhan.
1. Division: When the plant is 20-30 cm long and each pot has 10-20 branches, division can be carried out. Separate the plants with fine roots, carefully plant them in pots, place them in a greenhouse, water thoroughly, and then water every other day. When the branches and leaves recover vitality, water with a dilute liquid manure.
2. Layering: Pass the Zhusuan branches through the soil-filled pot and place it next to the large pot of the mother plant. Secure the pot with wire, and when roots form, cut it away from the mother plant to form a new seedling.
3. Cutting: Conducted during the plum rain season. Cut the current year's sturdy branches from the base into sections about 10 cm long, remove the lower leaves, and then plant them. After they survive, transfer them to the pot and cultivate them under the greenhouse. The next year, they can be moved to a sample pot.
Zhusuan is usually cultivated in lake soil in Wuhan. Watering varies with the season. Since it grows in a greenhouse, the amount of water is less than that of Bai Lan and Jasmine, aiming to keep the soil slightly moist. In spring (February, March, April), water once at noon every day. In the flowering period (May, June, July), water twice a day if the temperature is high, and water again if the soil is dry at noon. In August, September, and October, when the plant grows slowly, there's no need to water every day, about once every 4-5 days. In winter, let the water sit in the sun to slightly increase the temperature and water on sunny days to avoid frostbite. For fertilizing Zhusuan, it's best to apply thin fertilizer frequently. Zhusuan is usually repotted every 1-2 years in spring. When the tree is 14-15 years old, with fewer flowers, it's best to propagate new seedlings.
In the mass production of Zhusuan fragrant flowers, it is necessary to set up low greenhouses, hang the flowering branches with jute thread, known as "hanging flowers," to ensure good ventilation and increase flower yield. For small-scale cultivation, using bamboo stakes to support is also fine. In summer, Zhusuan grows in greenhouses and should spend winter in a greenhouse. During the plum rain season, Zhusuan is prone to rust disease, which can be prevented by spraying 0.8% Bordeaux mixture or a 1000:1 dilution of carbendazim from April.
That's all for the illustrated pruning method and related information about the cultivation and precautions of Zhusuan, hoping it helps you!
