Also known as Yushu, its branches and leaves contain a lot of Euphorbia. People who touch the juice of branches and leaves will cause redness, swelling, pain and blistering of the skin, which may lead to blindness if accidentally splashed into their eyes.
Yu Shuhua
Jade tree flower, also known as phoenix tail palm, is native to southern Africa. I like a warm, dry and sunny environment. Not cold-resistant, afraid of strong light, slightly resistant to shade. The soil is fertile sandy loam with good drainage. The temperature is not lower than 7℃ in winter.
type
Common cutting propagation. In the growing season, the full top branches with a length of 8- 10 cm are cut off, slightly dried and inserted into the sand bed, and take root about 3 weeks after insertion. You can also use single leaf cutting and dry it after cutting. Then insert it into the sand bed, take root about 4 weeks after insertion, and put it into the pot when the root is 2-3 cm long.
cultivate
Change pots and add rich soil every spring. Swallow's paw grows fast. In order to keep the plant plump, it is not advisable to have too much fertilizer and water. Water 2-3 times a week during the growing period, and strictly control watering in hot and humid July-August. Poor ventilation or excessive water shortage in midsummer can also cause leaves to turn yellow and fall off, so they should be maintained in a semi-shady place. After autumn, watering gradually decreases. When cultivating outdoors, avoid heavy rain, or there will be too much water in the roots, which will easily lead to the death of rotten roots. When changing pots every year or putting houses in autumn, attention should be paid to shaping and pruning to make the plant shape more elegant.
plant diseases and insect pests
The main diseases are carbon spot and leaf spot, and 70% thiophanate-methyl wettable powder 1000 times can be sprayed. The indoor ventilation is poor, and the stems and leaves are vulnerable to scale insects. Use 40% omethoate emulsion 1000 times solution for spray killing.
App application
Yushu flower has a tall and beautiful crown, green stems and leaves, and white flowers at the top, which is very elegant and chic. Decorative coffee tables and desks are more attractive if they are made into small bonsai with basin frames and gravel.
Yushu pruning can be done according to everyone's hobbies. If the crown is round and plump, the long branches will be cut off when pruning, which will make the crowded branches overlap too much, so that the external crown of the plant is complete and the internal branches are properly spaced. If the tree is long, the old trunk is thick and the crown is not round, it can be trimmed or stump bonsai, and some branches and leaves can be cut off according to the needs of modeling. Yushu is easy to raise, mainly to get more sunshine. Don't water it too much.
Yushu has strong adaptability, extreme drought resistance and lax requirements for soil. It is only necessary to keep the basin soil slightly moist and ventilated during the growth period, and it is not advisable to water it too much. If you water it after it is dry, the accumulated water in the basin will cause rotten roots. In summer, if the pot soil is too dry, it will also cause defoliation. Generally, little fertilizer is needed in the cultivation process, and only 1-2 times of dilute liquid fertilizer is needed throughout the year.
