Seedling raising methods of oleander

Oleander, also known as willow leaf peach, oleander is an evergreen shrub. Like light, warm and humid climate. It is lax in moisture requirements, has strong adaptability to soil, and can resist smoke and dust and some toxic gases. Oleander is like bamboo leaves and peach blossoms, and it blossoms when there are few flowers in summer, and the flowering period is long, especially the tree is strong. It is an important greening tree species in poor soil conditions, such as street, green belt, industry and mining. There are cutting, striping and other methods of propagation, mainly cutting. (1) hardwood cuttings shall be carried out in spring or early spring. Select thick branches with a diameter of about 1-1.5 cm (can use sprouting branches), cut cuttings with a length of 15-20 cm, tie dozens of cuttings in sequence, and immerse the lower part of the cuttings in 3 places in water for about 10 days. Should change water frequently, do not make immersion deterioration, when the cuttings are white, the top sticky, take out, insert into the seedbed. After immersion treatment, the cuttings grow fast and have a high survival rate. Generally, they can take root 15-20 days after cutting. Oleander can also be watered. Put the lower part of the cuttings in 20 ℃ water for 30-40 days, often change the water, and it is easy to take root. Then the cuttings after rooting are planted in the seedling bed for cultivation, but it is best to give shade. (2) it is easy to survive when oleander is used for strip propagation. Generally in the rainy season, before pressing, the branches close to the ground are injured and pressed into the water, which can be separated from the mother plant after about 60 days, and a new plant can be obtained.
