Yushu, also known as Swallow's Palm and Sedum, belongs to Sedum and Celastrus.
Originated in South Africa, it is cultivated all over the country. Evergreen shrub. The stem is cylindrical, gray-green and jointed. The leaves are opposite, flat, fleshy, oval, entire, slightly pointed at the top and rounded at the base. These flowers are red. Like warm and dry, sunny and well ventilated. I like loose sand. Avoid the soil from being too wet. Cutting is the main propagation method. Cuttings can be made of branches or leaves. Before cutting, cuttings should be dried in the shade. Cutting can be done in wet yellow sand or perlite in spring or autumn.
The cultivation and management of Swallow's Palm is simple and extensive, but there is indeed some work to be done to make the plants plump and strong and the flowers like mature trees. First of all, the swallows' claws grow very fast. Change pots every spring, add rich soil and keep them in sunny places for maintenance. Apply thin fat water every 10 day and a half, and water every 2 to 3 days, so that dry and wet will alternate. When the summer is hot, the swallows' palms are in a semi-dormant state, for fear that strong light will burn the leaves. At this time, it is necessary to do a good job of shading maintenance. Stop fertilizing in summer and pay attention to ventilation to prevent the leaves from turning yellow and falling off. If it rains heavily, avoid heavy rain and showers to avoid root death. From August to June, 5438+00, the autumn turned cold, and the phoenix tail palm began to grow again. It is necessary to strengthen the lighting again and remove the shading equipment. Fertilization and watering at this time are the same as in spring. Before the first frost enters the greenhouse, put it in a sunny place indoors and stop fertilizing and watering. Basically, water is poured once every half month, and the amount of water is half that of summer. Swallow palm is not cold-resistant in winter, and the temperature should be kept above 7℃. Prune once a year, change pots in spring or enter the greenhouse in late autumn to keep the plant shape elegant all year round.
Swallowtail swallowtail has less pests and diseases, and sometimes it will encounter anthracnose and leaf spot, so 70% thiophanate-methyl wettable powder 1000 times can be sprayed. If the indoor ventilation is poor, the stems and leaves are vulnerable to scale insects. When pests are found, they should be cleaned manually immediately. When the damage is serious, it can be controlled with 40% omethoate emulsion 1000 times solution.
The leaves of Yushu contain Euphorbia Euphorbia. When people touch the juice from the leaves, it will cause redness, swelling and pain, and even blindness if it is splashed in the eyes.
